When Should You Have Your Air Conditioner Coils Cleaned?

The air conditioner’s four most important components are the evaporator, condenser, expansion valve, and compressor.

Other parts that are far less critical or well-known than these four are also required for the air conditioner to function effectively. The coils are one of these.

Evaporator and condenser coils are the two different kinds of coils that may be found in air conditioners.

The evaporator coil eliminates heat and moisture from the moving inside air to cool it.

On the other hand, the condenser coil collects the heat and releases it outdoors.

These two coils must function flawlessly to guarantee that the air conditioner delivers cool, high-quality indoor air.

Like other components, the evaporator and condenser coils of the air conditioner might amass dust, which can impede the appliance’s performance.

The AC might malfunction if these parts are not carefully cleaned and maintained.

If you want your AC to keep your home cool with fresh air, you must have the condenser and evaporator coils frequently inspected, cleaned, and maintained. 

When Should You Clean Your AC Coils?

Air conditioner coils provide extremely apparent signals when they need to have an air duct cleaning right away. 

These indicators include:

Decreased Ability To Cool

The evaporator coils must be clean for your air conditioner to work correctly. Consequently, your house won’t feel cool even if you put on the air conditioning.

When each room has its cooling unit, this is quite visible.

If the evaporator coils in your central air conditioner are unclean, some rooms will seem warmer than others.

The evaporator coil requires cleaning, and your AC’s cooling ability has decreased if it takes longer than usual for air to be released at the proper temperature.

Rise In Internal Dampness

Heat and moisture are taken out of the air by the evaporator coil. Condensation happens every time heat is transported from the air to the evaporator.

When it is covered with dirt, less heat will be provided to the evaporator coil.

As a result, the apparatus will create less condensation.

Consequently, moisture vapor will continue to saturate the air in your house. Two more indications of rising interior humidity include misty windows and damp, clammy air.

Evaporator Coil Is Covered With Ice

The component is probably dirty when your unit operates if you notice ice on the evaporator coil.

The refrigerant temperature may decrease and freeze due to dirt and filth on the evaporator coil. As a result, this area of your AC will be covered in condensation and frost.

Your HVAC system may be unable to cool the inside air if there is too much ice on the coil.

Musty, Moldy Odor

Your air conditioner probably has dirty coils if it smells musty and moldy.

Your evaporator coil may develop fungus, which produces mildew if it is covered with dirt, filth, and bacteria. Until you clean the appliance, these pollutants will remain there and spread.

Moldy air will move around your house when the air conditioner operates, spreading bacteria and an unpleasant odor.

High Cost of Electricity

Even if there are no visible changes in the temperature or how frequently you use the air conditioner, an abnormally high energy bill might signal that your unit’s evaporator coil is dirty and covered in dust.

Your air conditioner won’t run as efficiently if the evaporator coil is unclean.

Frequently, inefficient AC systems consume more energy. Your energy expenditures will therefore go up.

Clean the AC coils immediately if any of these symptoms occur, or seek house cleaning in Edmonton that also cleans your air ducts. 


Your house’s comfort and aesthetic appeal will suffer if your air conditioner isn’t functioning correctly. To keep your home cozy and pleasant, maintain your unit periodically, watch out for any indications that it could have filthy coils, and get specialists who offer air duct cleaning in Edmonton.
