About Air Conditioner Coils


Coils are a significant part of an air conditioning system. It is important to understand what these coils achieve. Coils are serpentine copper tubing enclosed with aluminum fins. A compressor (pump) pushes a refrigerant through the air conditioning unit's coils and exchanges the warm interior air with cooler air. Air conditioners use two different coils to function correctly.


  • Air conditioners have two types of coils: evaporator coils and condenser coils. These are the two main components of an air conditioning unit. It is typical for the condenser coil to be positioned outside the building on concrete and the evaporator coil to be placed at the main duct connection over the heating system in split-system central air conditioners. Both components can be contained in a single unit in a packaged central air conditioning system.


  • The condenser coil is part of the condenser unit of the air conditioner system. It also includes refrigerant control valves, an exterior fan motor and additional controls. The condenser unit is a form of heat exchanger. The evaporator coil's low pressure makes the refrigerant into a vapor that removes heat. The air flowing through the evaporator coil is cooled. The cooled air flows into the interior by way of a fan and ductwork.


  • The temperature of a building can be controlled using an air conditioning unit. The two coils of the unit perform this task. The refrigeration cycle removes the heat from the inside environment to the outside and replaces it with cool air. This allows the interior of buildings to maintain specific temperatures.


  • Air conditioning units are manufactured for specific uses. It is vital to use a unit that can handle the workload required. The various types of systems must be researched to find the most suitable one. A professional should be consulted if there are any questions concerning the selection.


  • An air conditioning unit must receive maintenance on a regular basis to function sufficiently. The air conditioner coils and all other parts of the system should be inspected and cleaned when needed. A properly working air conditioner will use less energy and last for many years. Professionals or well-informed individuals can perform this service.
