Ductwork usually comes in rectangular or circular forms made from sheet metal. When a custom shape, such as a square, is required, you can build your ductwork from lightweight fiberglass duct boards. Sold in sheets usually 96 to 120 inches long and 1, 1 1/2 or 2 inches thick, the board can be cut and assembled to created custom duct shapes and sizes. The board also has insulating qualities that can improve duct efficiency over sheet metal.
In a typical heating and air conditioning system, you may encounter registers in the ceiling, on the wall, at the baseboard level or in the floor. Floor registers are common in front of patio doors or floor-to-ceiling windows. By placing the registers directly in front of the window, the air blowing out of them will "wash" up along the window, which helps prevent drafts. Once properly installed, you can walk across a floor register as if it were part of the floor.
Slab houses utilize a single layer of concrete that is several inches thick for the foundation. The slab rests on a bed of crushed gravel for drainage. On some older houses, the ductwork for the home may be under this concrete layer. This placement inevitably causes problems as the years pass and deterioration of the ductwork begins to affect conditions within the home.
Every home has ductwork to move the heating and air conditioning from the furnace to other rooms in the house. Pipes, electricity, gas, vacuum systems, security systems and other mechanical systems are also hidden inside the walls of homes. Most of the work to hide these necessary systems is done in the planning stages where the ducting, pipes and wires are routed through the various areas of the house to perform their functions -- ideally being set up using the least expensive duct runs within the parameters of the most practical layout.
A soffit is an enclosure that can create a tidy boxed look, especially in a basement, in place of leaving ductwork exposed. Soffits also refer to the underneath parts of eaves, arches, overhangs and staircases, coming from the Latin word “suffictus” meaning “to fasten underneath.” You can design your soffits so they come as close as possible to the ductwork without touching it, to avoid creating vibrations while keeping a good degree of headroom below the soffit.
Ductwork is shared by heating and cooling systems in most locales, even if separate units are involved. Some cool climates will have only heating systems, while warmer areas may have only cooling ystems. The basic design and layout of the ductwork is similar in all cases. Virtually all ductwork today is made of flexible flex duct, because it is easier and cheaper to install than metal ducts built on-site and is capable of the same or better airflow.
The firebox of an indoor fireplace is where you actually see the fire being produced. It will typically sit on a base and connect to the outside through a duct that goes through a wall. Installing a new fireplace is a difficult process if you haven't done it before, but one of the easiest steps is attaching the firebox to the ductwork, especially if that ductwork already exists.
Removing the gases generated by heating food, or the products of combustion from a gas stove, is important for the quality of air in your home. A stove with a downdraft ventilation system uses powerful blowers to draw these gases downward into the system and then out the ductwork. When installing a downdraft stove your current range hood's ventilation needs to be modified to extend the ductwork to the bottom of the wall.
A forced-air heating system, or heat pump combined with an air handler, requires a supply ductwork system to distribute heated air throughout the home. When building an addition, it may become necessary to tap into the existing system to install a branch line to heat the new room. Some larger room may also need an addition line to heat the space adequately.
Ductwork is used in every home and office building to deliver heated or cooled air to the structure. If you have noisy ductwork in your building or home, you can replace it. Over time, the ductwork can become worn or beaten. This will loosen the ductwork and make it noisy when air is moving through it. You don’t have to be a ductwork professional to replace noisy ductwork. You can do it yourself with little hassle.
Ductwork is a round or rectangular enclosed channel designed to transport gas, such as air, at low pressures. It is often necessary to reduce the diameter of ductwork for reasons related to location or performance. Generally, you can decrease the diameter of ductwork by installing a reduced fitting.
In areas of the country with low relative humidity, one of the most cost-effective air conditioning systems is a swamp cooler. Connecting a swamp cooler to the existing ductwork of a house involves placing the cooler in an area above the rooms to be cooled because a swamp cooler works by adding moisture to the air and having it evaporate to lower ambient air temperature. The moistened air is heavier than that of the dry air, so it descends into the lowest region available.
A tear in the ductwork can decrease the efficiency of heating and cooling systems and lead to a noticeable increase in heating or cooling costs. Despite its name, duct tape is one of the least effective ways to repair torn or otherwise damaged ductwork, as it will eventually dry and crack. Fortunately, it is possible to repair tears in ductwork with a combination of mastic and mesh tape. The repair process is straightforward and all of the materials needed are readily available at hardware stores.
Many people would rather let a professional handle the installation of cooling/heating ductwork, but some like to tackle projects of this nature themselves. Installing flexible ductwork may not appear to be that difficult, but prior knowledge alleviates some of the frustrations encountered along the way. It's important to consider that poorly-installed ductwork leads to increased electric bills. It can also cause your heating and air unit to work much harder, leading to a shorter life span of the unit.
Many basements, attics and converted industrial space will have exposed ductwork across the ceiling. The ductwork carries air conditioning and heating around the building, and it creates a decorating dilemma: How do you redecorate around duct work and what do you do with the ductwork itself? As long as you don't make the decorating too elaborate, you have a number of options for decorating the ductwork itself.
Modern apartments often show off the internal workings of the building, and refurbished industrial space sometimes leaves in original features. In particular, heating ducts, which snake across the ceiling, commonly remain exposed in these industrial and modern spaces. The easiest thing to do is embrace the ductwork as a feature, but there are a few ways to hide, conceal or simply improve on the appearance.
Central heating or heating and air conditioning systems use a system of galvanized ductwork to move treated air from the unit to the various rooms. The system consists of three components: return air, plenum and supply ducts. The return line pulls air from the living space into the unit where it's conditioned and distributed to the room. The plenum serves as a holding point for treated air. The supply duct delivers air from the plenum to the rooms.
Artificial limbs, computer parts, baby strollers and hundreds of other products are made from polyvinyl chloride, commonly known as PVC. According to the American Chemistry Council, 40 percent of the PVC molecule comes from petroleum while 60 percent is chlorine, from salt. Ductwork coated with PVC has durable underground applications that provide ventilation for crawl spaces and exhaust for toxic fumes, dust, bacteria and viruses.
Flexible ductwork is used to run air from a furnace or air-conditioning unit to vents in the house. Unlike regular ductwork, flexible ductwork can bend and fit into tighter areas. Over time, a piece or small section of your ductwork may become damaged and need to be replaced. When you are replacing a section of flexible ductwork, the most difficult task is getting to the section you are going to replace.
Ductwork in the crawlspace of homes commonly become damaged. Moisture is usually the problem in crawlspaces that causes steel ductwork to corrode. Once your ductwork has corroded, you must replace it to prevent air from escaping through the ductwork. For those without experience replacing ductwork, it can seem intimidating. Fortunately, with the right tools and directions, you can quickly replace the ductwork in the crawlspace and learn how to prevent it from corroding further.
Residential ductwork is usually shared by heating and cooling systems, but in some colder climates no cooling is required so the ducts are for heat only. The type of material used and the basic installation techniques are the same: use round ductwork whenever possible and make ducts as short and straight as you can. The most popular form of round duct is flex duct, a flexible material made of coiled wires covered with fiberglass insulation and sealed with a metallic outer coating. Round sheet metal ducts move air efficiently but lack the built-in insulation of flex duct.
Early ductwork systems for heating and air conditioning frequently lasted for long periods of time because of the materials used. Sheet metal and galvanized steel contributed to long-lasting reliability. However, modern ductwork particularly in homes, known by the industry as insulated flex duct, relies more on cheaper, more flexible tubing of plastic-wrapped insulation hoses. These easily can be damaged or snagged, requiring repair and replacement. Fortunately, the process is not hard if you're willing to get into tight places to do the work.
Ductwork is a system of ducts used in heating, ventilation and air conditioning. The ductwork attaches to the furnace or air conditioner and allows air to flow to different rooms in the house. Ductwork can be made of aluminum conduits or tubes that are snapped together. When you are installing a heating or air conditioning system, one of the first steps is sizing up the ductwork needed to keep the desired temperature in your house.
Industrial ductwork must be built to last. Instead of using thin aluminum ducts, commonly found in residential buildings, industrial buildings use steel ducts that are hung and secured with steel cables. This installation method ensures a sturdy, dependable duct system that is less likely to puncture and kink and that is positioned high enough away from employees to prevent danger should a puncture occur.
A basic knowledge of butchery allows any cook to enjoy preparing a wide variety of meats and meat cuts. A key implement in this endeavor is a high quality boning knife. Long a part of butchers' and professional chefs' arsenal of knives, they are now readily available to the domestic cook. Boning knives can be stiff or flexible depending on the meat they are being used to cut.
For people with asthma or allergies, duct cleaning is important. The U.S. Environmental Protection Agency states that duct cleaning doesn't necessarily have proven benefits, but it cannot hurt. Consumers must determine for themselves whether duct cleaning is an effective solution for their household health, but particulates in duct systems typically adhere to the inside of the duct and do not enter the home airspace. Cleaning companies can charge from $400 to $1,000 for a full duct service, according to EPA estimates. They use high powered HEPA filtered vacuums and sanitizers on the walls of the duct, clean the furnace unit…
Aluminum foil tape and aluminum flashing tape may look alike, but a closer inspection reveals technical differences that become very important in specific applications. The two types of tape should not be used interchangeably, as design, strength, and weatherproofing characteristics for the disparate adhesive products make them functionally dissimilar and inappropriate for use in select areas.
Joining ductwork is an essential part of installing or replacing a heating or cooling system. There are several different ways to complete the task, each with advantages and disadvantages. Professional installers use rivet guns and notched installation techniques, but a simple patch job is possible with duct sealant or even duct tape. There are even some twist lock systems available designed for installation without the need for extra hardware or tools of any kind.
Removing duct work is a challenging job for the simple fact that most duct work systems are located in hard-to-reach places. Ducts for heating and air conditioning systems are often placed in attics and small crawl spaces underneath the house. Duct work removal may be accomplished solo, but a helper comes in handy, especially when it's time to remove the duct work out of the space, or to remove clutter as the duct work is dismantled. A selection of basic tools and safety items are all that is required to remove most standard duct work.
Lining or insulating ductwork is a procedure that is gradually becoming more and more common with time. The process essentially makes use of fiberglass to insulate the interiors of ductwork. Installation is relatively quick, and can usually be completed within three to four hours in most home residences. This option is particularly appealing for many people because of the four primary advantages that it offers.
Homeowners need not rely on HVAC technicians to install air-conditioning ductwork. Anyone with patience and basic skills can complete the job at a fraction of the cost. Improve your chances of a successful installation by using flexible ducts, which compress and expand with ease and can be manipulated around existing fixed structures in your home. Consult experts at home improvement stores or friends with HVAC experience for tips, common mistakes to avoid and answers to any questions you may have.
Ductwork helps air flow through buildings to all rooms so that climate control systems can perform their functions correctly. For most modern houses, ductwork is installed along with building the basic house framework, so all costs are incorporated and overall expense for the project is lowered. But in older homes and houses without ductwork, owners may be interested in calculating the costs for an air conditioning and ductwork project separately so they can make future plans.
Planning ductwork is easiest when a house is under construction and you have access to framing elements to modify them to accommodate ducts. It is more difficult in an older house where central heating and cooling is just being added. The basics are the same, though: find the shortest, most direct routes from the heating/cooling unit to every vent in the house, size the ducts to handle the air flow needed and build a return system to collect "used" air from inside the house and drive it back to the unit to balance the unit's input and output.
Planning ductwork installation for an HVAC (Heating, Venting, Air Conditioning) system starts with a house plan, showing locations of ceiling and floor joists, wall spaces capable of containing ducts and obstacles to be avoided, such as water heaters and pipes and electrical boxes. It helps to have measurements; otherwise, measure potential routes with a tape measure to determine how much ductwork of each size is needed, where connectors will be located and how many are required. Use flexible duct, flexduct, wire cylinders covered with fiberglass insulation and sealed outside with a metallic barrier.
Look up in a building with exposed ductwork and you will likely see grilles cut directly into the side or bottom of the ductwork. You will also run into this situation in homes with unfinished basements. One or more grilles are cut into the duct trunks to help condition the basement air. Cutting in a grille requires a few common sheet metal tools available at any local home improvement store. A word of caution, though -- sheet metal ductwork is sharp and may cause severe cuts if you do not wear proper safety gear.
Ductwork design plays a key role in the ability of your heating and cooling system to evenly distribute air and maintain a consistent temperature throughout your home. Ducts that are poorly designed, improperly installed or inadequately sealed can affect temperature, humidity, indoor air quality and even be responsible for losing as much as 20 percent of the air you pay to condition.The goal of ductwork design should be to distribute air efficiently with minimal air loss or temperature fluctuations between the air handler and registers or returns.
Installing duct work for a room addition takes planning. Having the proper measurements to ensure the right amount of air reaches the room is important. For larger rooms, a home owner should determine whether or not the Heating, Ventilation and Air Conditioning (HVAC) unit is large enough to accommodate supplying air to another space. Measuring the length between the takeoff and the register in the new room will help to determine how much duct work is needed to complete the job.
The best heating and cooling unit won't work effectively in a home without proper ductwork to deliver conditioned air to the right places in the right amounts. Installing ductwork can be a major task in a finished house or fairly simple in one under construction, where walls, beams and cavities are exposed and easily accessible. Flex duct, a flexible cylinder formed around wires, covered in fiberglass insulation and shielded with a metallic heat and moisture barrier on the outside, is energy-efficient and fairly easy to install.
A plate heat exchanger is device that transfers thermal energy between two flowing substances. It is comprised of a central plate with grooves cut into it where the substances can flow and transfer heat between themselves. This type of heat exchanger is often the most efficient and compact, though it is also more expensive. You commonly find plate heat exchangers in computers and in condos, where space is at a premium and performance is needed.
Ductwork distributes heated or cooled air throughout a house. No matter how good the heating/cooling unit it is, it is not effective unless the ductwork functions efficiently. Good ductwork can save money; any leak or inefficiency is like sending money out the wall. Properly installed ducts last for years and lower your bills, but there are times when problems develop or changes in the house require duct replacement work. In most cases this is accomplished without major reconstruction.
In a plate heat exchanger, two substances flow through channels on each side of a plate and transfer heat from the hot substance to the cold substance. This type of heat exchanger is often used when space is limited and efficiency of the heat exchange is not very important, such as on-demand water heaters and high-powered computers. Mounting a plate heat can be really easy if screw holes are already provided or quite challenging if no holes are provided.
Sometimes nothing is better than a meal cooked to perfection on a charcoal grill on a beautiful summer evening. With the most basic grills, the level of heat is controlled with dampers. Learn how to best use your grill's dampers to keep the heat of the grill in harmony with the food you are cooking. Once you master the dampers, you can guarantee perfectly cooked meals for all of your friends and family.
Duct work is critical to both energy efficiency and comfort inside our homes, almost as much as the HVAC system it's attached to. If our heating and cooling equipment is the heart of our mechanical system, the duct work is the circulatory system that distributes conditioned air. When duct work runs through an unconditioned space such as a basement, garage or crawlspace, it is important that it be insulated to protect from heat gain or heat loss.
The design of ductwork is as important to a home heating and air conditioning system as the unit that powers it. Ducts that are improperly sized, installed with crimps or tight bends, have leaks or are not balanced between supply (conditioned air) and return ("used" air) will cause the system to operate inefficiently. Over time, such small problems may damage the unit. Ductwork is installed at the same time as the heating/air conditioning unit. If done properly, ductwork should last a lifetime.
Heat exchangers have just three parts: a container full of hot liquid or gas, a container full of cold liquid or gas and a means of putting them together. Heat moves from the hot medium to the cold. There are several types of heat exchangers with slightly different components; some with tubes within tubes, some with tubes in bigger vessels, and some special kinds of heat exchangers in which air and liquid meet or don't meet depending on the application.
Heat exchangers transfer heat between different mediums. You can use heat exchangers to heat air, steam, water or solid matter streams. They can be plate types, shell and tube, or plate and immersion designs. Heat exchangers can transfer heat from heated water pipes to radiators or heated steam pipes to heated air for warming homes and buildings. The standards for American heat exchanger specifications are set by the American Society of Mechanical Engineers (ASME) and American National Standards Institute (ANSI), their member organizations and the heat exchanger manufacturing industry.
An efficient ductwork layout is key to a good home-heating and cooling system. Ducts must be properly sized to distribute warm or cool air through the house. And a return system, to take "used" air back to the unit, must be balanced to handle the airflow from the supply side. Ductwork once was mostly metal; that still is used in some special situations, but the ducting of choice is a fiberglass product. The most efficient ductwork is flex duct, a round, flexible style formed of wires surrounded with fiberglass insulation and shielded with a metallic outer covering.
Ducts carry heated or cooled air throughout the home. Well-managed ducts prevent a lot of energy loss from your HVAC unit. After years of work, however, the adhesive and tape will begin to wear away. Holes may also appear when someone bumps the ducts, loosening the tape. The holes that appear should be patched to prevent energy loss from your system. Fixing your ducts is cheaper than the energy bills you'll get that result from a small leak.
Residential ductwork is almost always shared by heating and cooling. Installations which are only for air conditioning, in locales where heating is never needed, use the same basic techniques and materials. The material of choice is flex duct, a cylindrical duct formed with wires shielded by fiberglass insulation and wrapped in an air-tight blanket of metallic material. It is economical, easy to use and effective. It sometimes is combined with rigid ducts of sheet metal or rigid foam board in areas too confined for flex duct, but the round duct is more efficient at moving air.
Ductwork installation is easiest in a house under construction, especially if that house has a basement. Installation is trickier in a house built with a crawl space or on a slab and trickier still if the house is old and has never had central heating and cooling. There are similarities in all installations. Flexible duct is the ductwork of choice today, although sheet metal and fiberglass ductboard may be required in small or cramped areas.
Heat exchangers provide one predominant function both inside the home, for keeping rooms warm or cool depending on requirements, and for outdoor applications, such as geothermal energy production: They transfer heat to and from water or air supplies. Exact installation procedures depend on manufacturer and type of appliance, since heat exchangers have so many unique applications (furnaces, central heating, cooling systems in kitchens, swimming pools and even aircraft temperature controls), but many parts of the installation are common to all, so equip yourself with plenty of general information before you start your particular project.
Well designed duct systems are essential in conserving energy and preventing leaks in the home. A good duct system will also ensure that every room in your house maintains a comfortable temperature. If you find vast differences in the temperature in some rooms or leaks occurring in your home, it may be due to a poor air duct system. However, you can correct the issue as well as reduce your utility bill by minimizing the ductwork air flow.
Well maintained ductwork greatly improves the air quality in your home, saves energy and helps extend the life of air conditioning and heating systems. Do-it-yourself ductwork cleaning can save you money. The ductwork near the vent covers can be cleaned with regular household detergents and simple tools, for example. That said, sections deep in the duckwork require a professional cleaner due to the level of expertise and special tools required.
Duct board combines elements of sheet metal ductwork and flexible fiberglass ductwork sheathed with a plastic or metallic coating. Duct board is rigid, like sheet metal, but has fiberglass or similar insulation inside a plastic or metallic coating like flex duct. Duct board can be formed like sheet metal, but is easier to work with because it can be cut with a utility knife, although special tools are recommended, and has no sharp edges. It is used to replace large sheet metal outlets or plenums at the heating or cooling unit or in areas where flex duct is not feasible…
Proper ductwork is essential to efficient heating and cooling in a house. Ducts normally are installed during construction or when a new heating/cooling unit is installed. Often the vendor of the unit will install the ducts -- some won't give a warranty unless it does that work -- but a homeowner can install ductwork with some planning and effort. It requires no special tools but some help will be needed, especially if the house is large or has two stories. It's easiest if there is basement access.
A well-balanced duct work is mandatory for an effective air flow in a house from the heating or cooling unit. This requires a return system which takes used-up air back to the unit, and forces back conditioned air to circulate into your house. Typically, these supply vents are small in size and are found in the shape of rectangles, squares or circles. Return vents, though, are relatively larger in size and are located either on or close to floors, or close to the heating or cooling unit itself.
A water to air heat exchanger is a device that is used for a variety of heating and cooling applications. The device can fit into your existing hot air furnace's plenum. Install a water to air heat exchanger by placing it below your evaporator coil, cutting a hole into your ductwork the size of your unit and using tape and metal braces to secure your unit.
Good duct work is important, as it is vital to the efficiency of a heating and cooling unit. Ducts must be properly sized and installed for efficient flow of air from the heating/cooling unit through the house. Duct work has two elements: supply and return. The supply system is what carries heated or cooled air from the unit to the vents in various parts of the house. The return system takes "recirculated" air from the house back through the heating/cooling unit. When these elements are balanced and the return flow is equal to the supply flow, the system is running…
Ductwork in a house must be properly balanced to ensure an efficient flow of air from the heating/cooling unit. That means a return system, to take "used" air back into the unit, needs the same capacity as the supply system, which the unit uses to force conditioned air into the house. Supply vents are small, usually 10-by-12-inch rectangles or 8- or 10-inch squares or circles. Return vents are larger and usually located on or near floors and close to the heating/cooling unit.
Outdoor ductwork connects a heating or cooling unit with the indoor ducts. This ductwork supplies the heated or cooled air to the interior of the building. Since this ductwork is outside, there are some differences in installation, especially in protecting the ducts from the elements. While indoor ducts can be insulated with a wrap, outdoors a sealant and protectant are painted onto the finished installation.
Metal residential duct systems are fabricated using light-gauge galvanized steel. Home systems are usually low-pressure,1/2-inch water gauge with air movement measuring less than 1,000 feet per minute in the large, main ducts. Commercial and industrial applications are much larger and drive more air, necessitating heavier gauge steel and greater joint integrity. Joining metal ductwork in your home is done through attaching metal-to-metal joints called slips and drives, and fastening them with drive cleats and self-drilling, sheet metal, hex-head screws. Residential ducting is a combination of rectangular and round channels with adjustable elbows. Measurement and cutting is done on-site.
Residential homes often use heat exchangers to transfer heat more efficiently from one source to another. Double pipe, spiral, plate, and regenerative are just a few of the many types of heat exchangers available for purchase. You should always purchase your heat exchanger from a reputable heating contractor to ensure you have the proper sized exchanger to fit below your furnace and evaporator coil.
Good ductwork is key to energy efficiency. The best heating/cooling unit will not function effectively unless ducts distribute air efficiently throughout the house. Ducts must be routed to avoid obstructions, to connect all rooms and areas without too many branches or turns and to avoid any structural elements like piers, trusses or beams. Duct layout starts with an understanding of the capacities and functioning of the heating/cooling unit and its controls. It must include both supply and return ducts.
Leaking ductwork costs money every time the heater or air conditioner runs. Air conditioning duct installers close the duct's seams and wrap the joints with metal-backed duct tape before applying a mastic duct sealer -- not all local building codes require mastic covered seams and joints. The metal tape holds the duct together until the mastic dries. Metal duct tape sticks to fiberglass ductboard's outer liner, flexible tube duct's inner and outer liners and galvanized sheet-metal duct.
During home or office construction, builders must consider multiple factors, from how to arrange the electrical wiring to proper plumbing pipe installation. They also make decisions about ductwork, and whether they should install a flexible form of ducting.
Installing heating/cooling ductwork can be a really difficult job or a fairly easy task, depending on when and where the installation is. It is obviously easier in new construction or a major remodel, when floor and wall coverings are not present, but it can be done -- even in older houses not built for central heating/cooling. The most common ductwork today is flex duct, a round duct formed with wires and covered with insulation. It is efficient, easy to use and economical.
Learning about ductwork is a great way to educate yourself about air conditioning systems, whether it be for your own remodeling project or to start off on a career as an HVAC technician. Many home improvement stores offer free or paid classes that teach the basics of home ductwork where they will also touch upon ductwork fittings as part of their lesson plan. There are also dedicated HVAC trade schools that offer degree programs and individual classes.
Installing ductwork in a house is fairly simple, if you have adequate working space; it can be difficult if you have to work in tight areas, especially in older houses not built with central heating/cooling systems. Today's ductwork is mostly flexduct, a circular flexible material of wires covered with insulation. It is generally run between floor joists and fastened with metal strap hangers. If you're running it through an unfinished basement, it installs easily. If it must go in a crawl space or attic, it can be harder.
Maximizing ductwork in a small opening is a far more common situation in remodeling and building than in the past due to the increased heat load that personal computers are placing on A/C systems. Small openings normally restrict airflow because less air can get through but with the addition of a duct fan this restriction can be overcome. The duct fan creates a suction that increases the speed of the airflow to compensate for the smaller diameter ducting.
Both flashing tape and foil tape are made with an aluminum backing. The differences in the tapes come down to the components of the adhesive underside, as well as the applications for which they are used for. Flashing and foil tape are commonly used in construction applications because the adhesive acts as an efficient sealing component for devices suffering from cracks, holes and leaks.
A soffit is a type of bulkhead that is used to cover ducting that runs through your home. Ducting that cannot be placed in a wall or floor is typically routed along the edge of a ceiling. Hiding this ducting is done by concealing it in a soffit. To do this you will need to build or construct the soffit. Constructing a soffit is done by building a frame or forms that to go around the ducting.
Modifying a ductwork tube is sometimes a necessity, particularly if you meet obstacles in the path during the construction phase. Common ductwork is made from sheet metal. There are ready-made bend tubing sections to use, but bending it yourself allows flexibility in adjustments. However, flattening can occur in the radius of the bend, which normally requires specialized equipment to avoid. You can avoid this problem by using sand and heat to help bend your ductwork tube.
Ductwork is found in square, rectangular or round form. You may have occasion to measure the size of the ductwork. If you want to insulate your duct, measure it to cut the insulation to the right size. You may also want to know the measurements to accurately calculate the amount of airflow moving through the duct. Rectangular/square ductwork and round ductwork require different methods for calculating the measurements.
Ductwork is a system of flexible pipes or tubing that connects the individual vents of your home heating and air conditioning system to each room in your house. Ductwork is typically located in attics or crawlspaces in your home. From time to time, projects or work that you do in your attic, like laying insulation, will require that ductwork be moved or re-routed. This can be done very easily.
Many older homes have ductwork installed in or under the concrete slab foundation. When these ducts break or rust out, a homeowner is left with few options to deal with the problem. Installing new ducts through the attic is the best option. Running new ducts overhead is a permanent fix and much less invasive than trying to remove the old ducts by digging them out of the concrete and removing sections of walls if necessary. Ducts can also be coated with a fast hardening liquid PVC type of material in some cases if they are not too damaged. Only a…
Sometimes you have ductwork that just doesn't have any place to go. Building what is essentially a box, sometimes called a soffit, around ductwork or any kind of exposed piping, is a part of many home remodeling projects, especially basement ones. It can be time-consuming, and take a little patience, but you should find the finished look of a well-done soffit makes all the difference in the world to your project's appearance.
Heating, ventilation and air conditioning systems employ ductwork to direct air to and from a heating or air conditioning unit. Proper ductwork design and installation are critical steps in creating an efficient HVAC system.
Any home or office with a central heating and cooling system delivers air to each room and returns it again to the air handling unit through a series of insulated ducts. The condition of these ducts is a major factor in the overall efficiency of the system to heat and cool the building properly. Duct condition can also effect the quality of the air being circulated, as leaking ducts can introduce stale or polluted air into the system. Special measuring equipment can be used to determine any pressure loss in the ducts.
For maximum efficiency, ductwork needs to be insulated in certain circumstances. Ductwork warrants insulation when it is concealed above a drywall ceiling, above a suspended ceiling or in an attic. Basically, if you cannot visually see the ductwork serving the room you are in, it should be insulated. The main reasons for insulating ductwork are to maintain energy efficiency and to prevent condensation on the ductwork due to the temperature change. The above scenario always applies to supply air duct. Return air ductwork is insulated less frequently because it's basically room temperature air flowing back to the furnace. The only…
Choosing the ducting for a heating, ventilation, and air conditioning (HVAC) job depends on the desired effects of the duct work. Insulation is an important factor as heat loss or gain through the duct work can impact the efficiency of the system. Noise reduction can also be a consideration in jobs where the sound of the HVAC system must be reduced. Finally, moisture and condensation buildup on the ducts impacts the durability of the duct work and respiratory health as molds and bacteria can grow on the moist surfaces.
The ductwork in a home moves air throughout the house from the furnace or central air unit. Although filters in the furnace catch much of the dust and allergens, they cannot grab them all, leaving them to reside throughout the ductwork. Eventually the dust emerges through the registers and the return-air grills, leaving your house infested with tiny floating particles. With the right cleaning process you can lower the amount of allergens and dust in your home.
Ducts are the branches of the heating and cooling system of your home that provide the airflow from the main blower unit to the rest of the home. If an addition to the home is being made, or the system was inadequate due to age or other issues, new ducts or extensions can be added. Proper flow of air is the main concern. The system needs to be able to handle additional ductwork and it must be installed properly to get the benefit of duct extension.
Ducts are used in HVAC units for facilitating airflow. Airflow entails supplying, returning and exhausting air. Ducts are often called ductwork. Planning, designing, detailing, sizing, optimizing and finding the pressure loss are all part of the system called the duct design. Ductwork is insulated to enhance thermal performance and prevent dripping and condensation. The pipes used for ductwork are usually made of sheet metal, tin, flexible plastic or fiber glass.
Fiberglass ductwork is common in many households. Should you need to alter your ductwork the process is actually quite simple, requiring only a few simple tools in order to cut the ductwork to length. It's important that when you cut your ductwork that you always double check your measurements; or, as the old adage says, "measure twice, cut once."
Heating and cooling costs contribute a large percentage to the average home energy bill. Therefore, an energy-efficient house should have all ducts sealed properly to reduce the hot or cold air being leaked. Leaky ducts contribute to inefficiency and finding leaks in ducts should be a priority.
The proper installation of ductwork insulation is just as important as the insulation of walls and ceilings. Properly placed ductwork insulation can help save you money on heating and cooling costs by improving the efficiency of your air conditioner and heater, because it will eliminate escaping cold and hot air. The insulation of ductwork elbows, because of the angles at which they bend, can be tricky. These steps will help you handle the task.
The dampers in a home's duct work work as valves to control the flow of air. Dampers are used to balance the HVAC (Heating, Ventilating, and Air-Conditioning) system; a balanced system is more efficient and more comfortable. Although much of the work of balancing an HVAC system is done when the components are selected and the ductwork is installed, it is important to use the dampers to fine-tune the system. Please note that the damper positions may need to be changed depending upon whether the system is heating or cooling.
If you want to add a new duct run in your home, you need to calculate the size of the duct needed to supply that room. The duct size is dependent on the CFM that you will be supplying that room. CFM stands for cubic feet per minute. If a room is supplied with 100 CFM, that means there will be 100 cubic feet of air dispensed into that room each minute. Duct runs that are too small will not supply enough air and will have increased velocity, which leads to noise. Duct runs that are too big will have…
Return ductwork acts as part of the heating, ventilating and air conditioning (HVAC) system. It extracts air from inside a home and sends it to the air handler which recycles it for redistribution back into the house.
Homes and buildings with central-air units depend on ductwork to dispense warm or cool air. Modern ductwork has insulated, bendable tubing that attaches to ceilings, runs across attic floors or functions underneath a structure. Ductwork regulations are written to make distinctions between residential and industrial designs. The rules often change to meet local and national energy standards.
Foil tape is a versatile product with a multitude of applications and product styles. The fact that it is highly conformable and tolerates temperature changes makes it the perfect product for sealing duct work, and its weather resistant quality means it can be used on duct in both indoor and outdoor environments. It's also easy to use foil tape, according to Jason Shirley, an HVAC installer. The tape, Shirley says, smooths out nicely and gives the job a professional appearance.
When installing ductwork, you have a variety of different fittings at your fingertips to suit your individual needs. Ductwork tees are one of these fittings, and they are used to split a single trunk of duct into two separate duct trunks. Tees can be purchased from your local home improvement store in a variety of sizes, so there should be one that suits your needs. Their installation is simple, and you need only a few tools to complete it.
Whether you're adding on to existing ductwork or building from scratch, the type of duct you choose and the way you install it can affect your home heating and air conditioning system's efficiency later. Duct for heating and air conditioning systems is typically made out of metal. You can purchase any missing or broken parts from a home improvement store.
Running duct work and all other heating and air conditioning-related jobs are regulated by the local building codes and the HVAC industry. Building codes are as varied as the state and county agencies who write them, so be sure to check with your local building inspector’s office before doing duct work yourself, only to learn it all has to be torn out and replaced by a licensed installer. Flexible duct has made this a doable home owner task, at least mechanically, if you do not mind crawling around under the house or in the attic all day.
Ductwork carries the air from the furnace or air conditioning to all the rooms in a house. Performing maintenance and upgrades on ductwork can increase the efficiency of your heating and cooling systems. These projects will, in turn, save you money on your utility bills.
All forced-air heating and cooling HVAC systems require a vast ductwork system to carry the cold or warm air, depending on the season, throughout the house. How well the ductwork is sealed dictates how efficient the entire system really is. A high-efficiency furnace or air conditioning air handler will not perform as well if the ductwork is leaking at every seam. Properly sealing ductwork optimizes energy efficiency with forced air systems.
HVAC system design is an area of expertise to many mechanical engineers. They design HVAC systems so that the equipment will perform to optimal efficiency. However, modern products are certainly not the products of yesterday, and even the best mechanical engineers designed HVAC systems with some quirky aspects. One of those is ductwork in slabs.
Snap together duct work can be installed in any room of your home to ventilate and send hot or cool air from a furnace or air-conditioning unit. The duct work is designed to be simple to install, with locking components on each pipe. Easy to snap together, the duct systems are ideal for do-it-yourselfers and used in many different types of homes and buildings.
Ductwork that brings warm and cool air to the living spaces of your home may also be carrying it to places where it goes to waste, such as the attic, garage and crawl spaces. In fact, the U.S. Department of Energy estimates that poorly sealed, poorly insulated ducts can waste up to 30 percent of the energy that goes into heating and cooling your home. Ductwork is usually made of thin metal that easily conducts heat, which is why it's critical to seal and insulate it properly. Taking the time to seal and add insulation so can save you hundreds…
Decorating older homes--or basements in newer homes--can be challenge if there is exposed ductwork in the ceiling. Many people choose to have a professional come in and install a drop ceiling to cover the ducts that are visible, but that can be quite expensive. To include the ductwork in your room's design, learn how to properly decorate it.
The ductwork of your home will be made of either fiberglass or sheet metal. The measuring and marking procedures for the two materials is the same, but the tools required for cutting are vastly different. When cutting sheet metal, you need hand and power tools designed to cut metal, and with fiberglass you only need a long, sharp knife. With both types of materials, you need to follow the saying, "measure twice and cut once." to ensure that you cut the duct to the correct length.
When installing ductwork, it is inevitable that you will need to offset the duct line to avoid obstacles or connect to the air-handling unit. There are numerous ways to calculate the cut required to make an offset from a straight length of duct. The formula offset x width / length (O.W.L.) is a good option if you have excellent math skills or a calculator. If you need to figure an offset cut quickly, another option is fast and as accurate as using O.W.L.
Ductwork runs throughout an entire house or building and is a main component of your ventilation system. Naturally, it is important to keep these ducts clean and sanitized to prevent the spread of germs and spores through the air. Mold is the primary concern with ducts, as it can easily build up in these isolated areas and can be tough to eradicate. Properly sanitizing a duct consists of a great deal of work, and the equipment required to sanitize the ducts correctly can be expensive. It is important to weigh the costs of buying the equipment yourself against hiring professionals…
Ductwork is used for heating and cooling systems (HVAC). Since one's house or building is longer than a single length of a metal duct, it's necessary to have more than one duct attached together. And because these lengths need to be supported so that the air flows without impediment inside them, it's necessary to know how to properly hang metal ductwork.
The ductwork in your home supplies conditioned air to each room of your house. When you have leaks in your ductwork, the airflow is reduced throughout your home, costing you money. If the return ductwork of your HVAC system leaks, contaminated air pulls into the duct system from your attic or basement. This causes the air quality of your home to deteriorate and can cause problems with your family's health. Using a mastic duct sealer to seal the leaks in your ductwork will ensure that your ductwork will remain leak free for many years.
Flexible ductwork has many advantages over standard metal ductwork. It is easier to cut, requiring no special tools, it has an outer covering of insulation included and it may install quicker than metal ductwork. There are some attributes of the flexible nature that do require extra attention when you are installing it as placement away from heat sources, adding extra support and gentle turns instead of sharp bends in the process.
Correct installation of ductwork is important in houses that use central heating or cooling systems. Ducts circulate the air and ventilate rooms, so if installation is done incorrectly the residents may experience poor ventilation, uneven heating, sometimes a substantial noise level. When ductwork is done properly not only are these discomforts avoided, but home owners may save $50-$200 or more a year on heating bills.
Whether you are installing a new central heating and air conditioning unit or repairing an existing one the right ductwork is key. Keeping that ductwork in top shape is critical for energy efficiency and the best way to keep your costs as low as possible. Understanding how those ducts work and what makes them important will help you save money while reducing the chances for a breakdown.
Painting galvanized ductwork is a great way to hide it or help give it a finished look. It's not hard and will dramatically change the appearance of the room. Any good paint store can match your room color and mix the paint for you so you can achieve the look you want.
Ductwork cleaning is generally done by a professional company. They use specialized equipment to thoroughly clean the entire ductwork system. However, much of the dirt and dust in ductwork accumulates near the vents or registers, making it easy for someone to partially clean the ductwork in her home. Otherwise, a professional service needs to be utilized to clean out the ductwork entirely. Basic ductwork cleaning can provide cleaner air in your home and can be done with relative quickness and ease.
Exposed ductwork can be ugly or just not the look you're going for. Enclosing ductwork is fairly simple, but it is usually effectively done in only one way and that's to enclose it with framing and drywall it over. It's not hard to do, but requires a bit of home repair skills and a few hours of work.
Using a soffit to conceal duct work is a great way to improve the interior appearance of your home or business. Constructing a soffit is easier than you may think and will add enormous value to an interior. Although some modern designs chose to leave ductwork exposed, those who prefer a more traditional look should follow the following steps to hide any exposed ductwork.
Installing air conditioning ductwork is a critical step that will determine how well your house is cooled by your air conditioning system. Ensuring that the flow of air is efficient, air-tight and circular will put less stress on your air conditioning unit, reduce energy bills, and cool the house to a greater degree overall. Every state has specific codes and regulations specifying how to install air conditioning ducts; you must also consult the Air Conditioning Contractors of America (ACCA) Manuals D, J, and S for further installation information.
Ductwork is a system of metal ducts or pipes that carry air throughout a building. They are used to supply heating, air conditioning, and ventilation, and are a major part of a building's operation and airflow. A properly designed ductwork system will be energy efficient and properly sized to condition the building it is in. These systems are designed by mechanical engineers and installed by mechanical or sheet metal contractors, who fabricate the materials according to the engineer's plans.
Replacing the ductwork in a house is a tough job whether it is located under the house or in the attic. Even then, the restricted space will cause the job to go slow, so plan this when there is plenty of time to do it correctly. Take every precaution to protect yourself from the fiberglass insulation that you will be working around. It can be a skin irritant, but it can also cause damage to your lungs. It is highly recommended that some sort of breathing apparatus be worn, as well as skin and eye protection. The most common ducts…
With all the money we spend controlling the temperature in our homes, the last thing we need is to counteract that effort with blow back from the clothes dryer or from outside air. Dampers prevent this unwanted air from blowing back in the house and are relatively easy to do yourself as long as the ductwork is accessible. In-line dampers also can help move the wanted air from room to room.
