Schedule Evaporator Coil Cleaning When You Notice These Signs

Signs You May Need Professional Evaporator Coil Cleaning

When a house fails to reach the desired temperature on the thermostat or experiences other issues, it may be due to several reasons. While homeowners most often put the blame on their air conditioner or heater as a whole, it could also be due to a dirty evaporator coil. 

An evaporator coil removes hot air from a house and disperses cold air to cool the property when used with an air conditioner. If it malfunctions or gets dirty, the system’s performance can suffer. To prevent this, homeowners must schedule evaporator coil cleaning services at the first signs of a problem, including if there is a frost build-up on AC coils, the system runs longer than normal, or the house is not heating or cooling correctly. 

Loss of Heating or Cooling Function

hotOne of the most noticeable signs of a dirty evaporator coil is if a house is not reaching the desired temperature setting on the thermostat. It may be subtle, but members of the household may start to notice the house feels warmer or cooler than it should be or stuffier. 

An evaporator coil can fail to cool or heat a house correctly due to several reasons, including if there is a refrigerant leak from the coil, if there is frost building up on the coil, if it is corroding, or if there is dust, dirt, or debris building up on the component. Property owners should schedule evaporator coil services with an HVAC contractor at the first signs of an issue to determine if they need coil cleaning or other services.

Frozen Evaporator Coil

frostAnother problem that can cause an evaporator coil to malfunction is if there is a frost build-up on it or it’s frozen. Ice on the unit will prevent it from working properly and prevent air from correctly flowing through the device. But frost on the coils can be caused by them getting dirty or refrigerant leaking from it. 

Frost can also form if there is a clogged or dirty air filter or another cause of low airflow in the HVAC system. If the frozen coils are due to an issue with the evaporator coil, like low refrigerant or dirty coils, evaporator coil services and cleaning will be needed. 

The AC or Heater Runs Too Long

If the heater and AC evaporator coils are dirty, homeowners might notice the air conditioner or heater running longer than necessary. Longer cycles can be problematic as they can cause the unit to overwork, resulting in higher energy bills. A dirty evaporator coil can cause them to run longer or continuously if frost, dirt, or dust buildup on the evaporator coils prevents the heat exchange process from working correctly. 

Homeowners can help prevent these issues by scheduling routine maintenance and then scheduling evaporator cleaning services as soon as they notice the symptoms of dirty evaporator coils, such as a loss of function and comfort, frozen coils, or longer HVAC system cycles.
