The coils are the most important part of your HVAC system, because that’s where the heat exchange happens. It’s helpful to know what the coils do for your HVAC, but even more important to properly maintain your coils.
You’ll find 2 sets of coils:
- One indoor coil.
- And one outdoor coil which acts as a condenser and the indoor is an evaporator coil.
Because the setup and location of coils differs from model to model, you’ll want to have a licensed Jewell Mechanical technician perform regular maintenance.
The HVAC Evaporator Coil
Your evaporator coil is located indoors in line with the ductwork. Depending on whether you have your AC or furnace engaged, the evaporator either pulls heat from the existing air to cool it, or adds heat to the air to heat it. Refrigerant moves through the coil as air is pushed over it, resulting in cool or warm air that then is circulated through your house.
The HVAC Condenser Coil
The condenser coil works to regulate the temperature of the refrigerant. The refrigerant circulates through the condenser coils and changes temperature before being sent back to the evaporator coil. Because this coil is located in your outdoor unit, the heat energy that transferred to the refrigerant in the evaporator coil can be released into the outdoor air.
Keep Your Coils Clean
The coils come in direct contact with the air that circulates through your HVAC system, so it’s important to ensure that the coils are kept clean and undamaged. Dirt and dust that builds up on your coils act as insulation. Any extra insulation makes your system work harder to heat or cool the air.
Dirty interior evaporator coils can keep your system from effectively heating or cooling the air, and can result in smelly air or a buildup of allergens. Keep these in good shape by having them routinely serviced and cleaned, and change your air filters regularly.
The outdoor compressor system brings its own set of challenges. While this air doesn’t directly enter your house, airborne dust, dirt, and debris can build up on the compressor coils. This will cause the compressor to work harder to perform the necessary heat exchange.
Get these compressor coils checked and cleaned during your routine maintenance. Be aware of any outstanding conditions that may cause extra dirt and dust in the air, such as nearby construction or long stretches of dry weather. Cut back plants and trees for several feet around the unit to increase airflow.
