Evaporator Coil Cleaning: When to Schedule Services

Signs You Need Professional Evaporator Coil Cleaning

When the house is not cooling to the desired temperature even though the air conditioner is running, it can signal the system’s evaporator coil needs to be cleaned or serviced. 

A dirty evaporator coil can cause many negative effects, including causing an AC unit to overwork and leading to higher energy bills. To avoid these problems and keep their house cool and comfortable all summer, AC contractors recommend that homeowners watch for signs indicating their coil needs to be cleaned. 

Loss of Cooling Function

One of the first symptoms homeowners may notice that can indicate a dirty evaporator coil is if the house seems warmer than it should be. If it fails to cool the house, homeowners might start adjusting the thermostat or fear a major issue with the air conditioner. However, this can be due to a dirty evaporator coil. 

Some other signs of dirty coils homeowners should be aware of include:

• There is frost or ice on the coil
• The coil is damaged
• There are signs of corrosion on the coil
• There is dust, dirt, or debris on the coil

If homeowners notice these symptoms, they should call an AC contractor to schedule evaporator coil cleaning services.

Frost

Frost or ice on AC coils requires professional services. An expert must remove the buildup to prevent the coil and the air conditioner from malfunctioning. 

If there is frost on AC evaporator coils, it can prevent air from properly flowing through the component. This can occur with a clogged air filter or a blocked vent. 

When ice or frost is suspected on an evaporator coil, a professional must repair or clean it quickly to enable the air conditioner to function properly. Frozen evaporator coils should be treated immediately!

The AC Runs Longer

Another sign that an evaporator coil needs to be cleaned or repaired is if a home’s air conditioner runs longer than expected without turning off. Longer cycles can be problematic as they can cause the air conditioner to overwork and increase energy bills. 

An AC system can fail to turn off properly due to a dirty coil if there are buildups of frost, dirt, or other debris. Continuous running can also be due to a problem with the heat exchange process or can signal there is a malfunctioning sensor.

Homeowners should schedule regular evaporator cleaning services to prevent an air conditioner from malfunctioning due to a dirty evaporator coil. The sooner professional services are booked, the sooner an AC system can get up and running again, and an ideal temperature can be restored in a home.
