What Is an Evaporator Coil?

The two main components of an air conditioner are the condenser and the evaporator coil. An evaporator coil is a vital part of the cooling system because it removes heat from indoor air and transfers it into a refrigerant. Next, the condenser removes the heat from the refrigerant and transfers that heat outdoors and the cold air gets pushed in via the air ducts.

Evaporator Coil Problem Signs

  • Warm air blowing through the air vents
  • Air conditioner turns on and off frequently without effective cooling
  • Strange sounds, such as hissing, clanging, or banging
  • Leaks around the indoor unit
  • The air conditioner won’t turn on

Things to Keep in Mind...

Your evaporator coil is located behind an access panel on your AC system. Because the cooling process produces condensation in the coil, and the air handler blows around dust and debris close by, the coil is at risk of becoming very dirty and even moldy. Just one season of use could create a layer of dirt that needs to be cleaned before your air conditioner can go back to functioning at full efficiency.

If you happen to notice a musty smell in your house, it could be because of a dirty coil because the air blowing across it picks up dust and mold particles and pushes them through your air ducts. Without having your evaporator coil professionally cleaned, the overworked coil eventually freezes and results in overall system failure. Call a professional before it's too late.
