When your air conditioner isn’t cooling properly, ice has probably developed on your AC unit. If your air conditioner is blowing warm air, you may hear that you have a problem with your evaporator coils. The evaporator coils are a major component that helps your air conditioner create cool air for your home. To better understand how the evaporator coils work and how important it is to maintain and keep the coils clean, Air Supply Heating & Air Conditioning will share the basics.
How Does an Evaporator Coil Work?
A home’s air will consist of heat and moisture. When the air conditioner runs a cycle, the air will become cool and have less humidity. This is all because of the air conditioner’s evaporator coils. As the warm air from inside the house passes over the evaporator coils, the evaporator coils remove the heat as well as the moisture from the air. Basically, the evaporator coils is where all of the cool air comes from. Without the evaporator coils your home will stay warm. The evaporator coils receive the liquid refrigerant from the air conditioner’s condenser coil and the compressor. The fan will blow the warm air from inside the home and over the evaporator coils. The refrigerant absorbs the heat from the air. While the heat is being absorbed, the evaporator coils are also dehumidifying the air at the same time. Water vapor will cause condensation to collect along the coil where the droplets are collected in the condensate drainage system.
Where are the Evaporator Coils Located?
An air conditioner will have evaporator coils that work with the refrigerant to cool the air. The evaporator coil often makes a “U” or “V” shape that has thin metal fins and a tube made of copper, aluminum, or steel. Depending on your air conditioner system, the evaporator coils may be located in different areas. If you have a split cooling system the evaporator coil will be located in the air handler. In a single unit or compact air conditioner system, the evaporator coils will be inside a single unit.
Why is it Important to Keep Evaporator Coils Clean?
The evaporator coils do require maintenance. When the vapor collects on the evaporator coils dust and other debris will also fall and get stuck in the small drops of water. Over time a muddy like grime will build up on the evaporator coils. When the evaporator coils have too much dirt and grime built up, the evaporator coil cannot absorb the heat or humidity in the air. You will often notice warm air blowing from the air vents. Another common sign that the evaporator coils are dirty, is that ice will form on the air conditioner. The entire air conditioning system will fail to operate properly. The evaporator coils will need to be cleaned to ensure the air conditioner cools the air, but also improves the air conditioner’s performance.

It is important to make sure your evaporator coils are cleaned at least once a year. During a routine air conditioner tune-up, the evaporator coils are cleaned.
