About Duct Cleaning

Regular duct cleaning is required to maintain the air quality in your home. The design of most metal ducting systems causes dirt and other residue to collect inside the corrugated material and rounded corners. Periodically cleaning the air ducts also prevents debris from building up and attracting rodents or other vermin into your home. Cleaning the ducts yourself will save a significant amount of money, but it can be a difficult task if you do not have the proper tools to reach deep into the duct system.

Benefits

Over time, dust, smoke and mold build up inside the ductwork of your home. When the heater or air conditioner is turned on, these particles are blown into every room of the house. This can lead to respiratory problems or aggravate allergies and asthma. Duct cleaning removes the harmful pollutants before they can be distributed throughout the home.

Function

When cleaning the ducts in a home, you want to get rid of all the built-up dirt, dust, mold and other debris, especially in the corners of the ductwork. The air register covers are removed and cleaned, opening up access to the inside of the ducts. The ducts are then cleaned with vacuums and long-reaching brushes. To finish the job, the outside of the HVAC unit is cleaned off and the air filters are replaced.

Time Frame

It is best to clean your home's air ducts every 3 to 5 years, depending on your air quality and health. People with asthma, allergies or other breathing problems may want to have the ducts cleaned more frequently to improve the air quality inside the house. Homes with pets or residents who smoke will also need duct cleaning more often.

Expert Insight

You may need a professional duct cleaner if you see visible spots of dirt or mold on the outside of your home's air register covers. This can be a sign of contamination inside the ducts and may require replacement of the affected area. Professional duct cleaners can also spray a microbial or antibacterial solution inside the duct system to reduce future pollutants in the home.

Amount

Professional duct cleaning generally ranges in price from $450 to $1,000 per system. This price may vary based on the size of the ducting system to be cleaned, contamination level, climate and difficulty of access. Special treatments, such as antibacterial sprays, are usually charged separately.
