Symptoms an Evaporator Coil Needs Cleaning

Signs You Need Professional Evaporator Coil Cleaning

An evaporator coil plays an integral part in keeping homes cool. These components allow air conditioners to remove hot air and disperse cooled air throughout a home. To prevent these problems from interfering with an air conditioner and causing a home to become uncomfortable, homeowners should schedule professional coil cleaning services. These services will allow an AC unit to operate more energy efficiently and better cool a home.

Homeowners should schedule evaporator coil services if their HVAC is not properly cooling their house, if frost builds up on the component, or if other problems prevent it from properly cooling the house.

Loss of Cooling Function

One symptom homeowners need to be aware of that can indicate they need to schedule evaporator coil cleaning services is if their house is not cooling to the setting on the thermostat. A dirty coil can prevent the air conditioner from properly cooling a house.

This can be due to:

  • Frost or ice built up on the coil
  • Refrigerant leaks
  • Coil corrosion or damage to the component
  • Clogged coils due to dust, dirt, or debris

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


Frost on an evaporator coil can require professional AC coil cleaning services to remove it and allow an air conditioner to work correctly.

If frost accumulates on a coil, it can prevent airflow from properly going through a coil. This can happen for various reasons, including a clogged air filter or a blocked vent. This prevents the coil from correctly absorbing heat and producing cooled air.

Property owners must call for professional services immediately if they have frozen evaporator coils.

The AC Runs Longer

Homeowners should also look for signs that their air conditioner is running longer than necessary to determine if they have dirty evaporator coils. Symptoms of longer cycles can be seen in rising utility bills.

This happens when an evaporator coil is dirty and cannot correctly cool the house to the desired temperature. It can cause the AC unit to run continuously by:

  • Reducing the cooling efficiency due to frost buildup or dirt accumulation
  • Failing to absorb heat from the air correctly
  • Overworking due to a faulty heat exchange process
  • Inconsistent cooling throughout the house
  • Malfunctioning sensor that prevents the air conditioner from turning off

Homeowners should schedule AC evaporator coil cleaning services with a professional if they notice any of these issues. An AC contractor will inspect the component and the entire AC system and perform necessary repairs or services.
