When Do AC Evaporator Coils Need Cleaning

Making Sure AC Evaporator Coils Are Clean as Can Be

Though the summer months are great for going outdoors or lounging around a beach or lake, they can put a lot of stress on the home’s HVAC system. Because you’re depending on it to constantly keep the house cool and comfortable - routine care is more important now than ever. An evaporator coil is a critical part of the AC system because it absorbs the heat from the air, leaving the cold air to flow through the home. 

In this article, homeowners can learn more about the functions of an evaporator coil and how to keep this essential AC component functioning properly.

Dirty Evaporator Coils Are Causing Concerns

Dirty Evaporator Coil

Dirt is the arch-nemesis of your air conditioner. It causes all sorts of inefficiencies, especially when the evaporator coil gets dirty. But unfortunately, it happens all the time. The important thing is to recognize the common signs of a dirty coil and have the coils cleaned as soon as possible. 

Here are a few signs to keep an eye out for:

  • The air doesn’t stay cool: When the evaporator coil is dirty, it can’t absorb enough heat from the air in the house, which prevents the air from being cooled. So if the AC is still kicking on but temperatures feel higher than usual, it may be a dirty coil causing the problem.
  • Non-stop cycles: The AC automatically turns on based on the temperature set on the thermostat. But if the evaporator coil is dirty, the air doesn’t cool efficiently, so the AC keeps running and running. This will increase your energy bill and, if it continues to happen, the AC will eventually wear itself out, shortening the lifespan of the unit.
  • A frozen coil: If dirt builds up on the evaporator coil, condensation can occur and turn to ice. When the coil freezes, it can cause the whole AC system to shut down. This is a major HVAC emergency and can bring on stress, hassle, and expensive repairs.

If homeowners want the air in their home to stay cool and want to avoid HVAC emergencies like a total shutdown from a frozen coil, it’s best to keep the evaporator coil clean. But how is this done? Can homeowners take on this task themselves? Some may try. After all, there are tons of DIY home repair articles out there explaining the steps for cleaning a coil. But trying to do so with little to no HVAC experience can be unsafe or could end up causing more harm to your unit than good if it’s done incorrectly. 

Therefore, it’s best to leave it to the professionals to handle the cleaning process. Once homeowners identify the signs of a dirty coil, they’ve done their part and should call in a pro to do the rest. 

Leaving AC Services to the Professionals

When it comes to AC services, whether it’s cleaning a dirty evaporator coil or some other maintenance task, it’s best to hire a professional to do the job. Many homeowners like to try the DIY route first. But make one wrong move and it can cause something else to leak, become damaged, or malfunction. These small mistakes can cause a lot of hassles and expenses when additional repairs need to be made down the road. 

A trained professional will have all of the knowledge, experience, and tools to handle the situation the right way from the start. Additionally, they can identify other issues that may be happening within the HVAC system that a homeowner likely would not recognize themselves.
