Signs You Need Evaporator Coil Cleaning

When To Schedule Professional Evaporator Coil Cleaning

When homeowners notice that their air conditioner is running, but their house is not cooling off, it can indicate they need evaporator coil cleaning services. If debris or frost builds up on the coil, it cannot work properly. And to run correctly, air conditioners rely on evaporator coils.

These coils help remove hot air from homes and send cool air through the house. The house cannot cool to the desired temperature if the evaporator coil malfunctions.

Fortunately, scheduling evaporator cleaning services can prevent these problems. Households should schedule an appointment if they notice their HVAC is not properly cooling their house, if there is frost on the coil, or if other problems prevent it from properly cooling the house.

Loss of Cooling Function

One of the biggest effects of a dirty evaporator coil is if the house fails to cool to the desired temperature. When a family notices the house feels warmer or stuffier than usual, it can signal a problem with the evaporator coil.

If there is frost or ice built up on the AC coils, if the coils are corroding or damaged, or if there is dust, dirt, or debris built up on the device, it can fail to work properly.

If homeowners notice these symptoms, they should call an AC contractor to inspect the air conditioner and schedule cleaning services on the AC evaporator coils. During an appointment, technicians can also ensure the problem is due to a dirty coil and not another problem, including a refrigerant leak.


When frost accumulates on an evaporator coil, it should be removed during professional coil cleaning services. If there is frost build up on the coil, the air conditioner will not be able to properly cool the house.

Frost can develop on the coil if there is a blocked vent or air filter. When frozen evaporator coils occur, the frost can prevent air from properly flowing through the component, and will not allow the AC to operate correctly.

The AC Runs Longer

A dirty evaporator coil can also cause air conditioners to run continuously – even when the house has cooled to the desired temperature. This can lead to the air conditioner overworking and can cause energy bills to increase.

A dirty evaporator coil can cause an AC unit to run continuously by creating an issue in the heat exchange process or interfering with the sensor that prevents the air conditioner from knowing when it needs to turn off.

Fortunately, homeowners can prevent longer cycles by scheduling evaporator coil cleaning services when they first start to notice problems like inconsistent cooling, or if their house fails to cool to the setting on the thermostat.
