We have two parts for cleaning air conditioner coils – condenser coils and evaporator coils.
Although you might think the process is the same, there are a couple of things that are completely different.
Let’s first talk about condenser coils.
How To Clean Your Air Conditioner Condenser Coil
As I want to simplify everything for you, I’ll lay out this process in simple 5 steps:
- Shut off your unit completely
- Remove the debris and any grass around the exterior
- Take a good look at all the possible damages in fins
- Grab your coil cleaner and spray coils
- Take another look for damages after cleaning it
You can watch this process in action on this video.
📍 Note: Sometimes cleaning can’t do anything impactful, so it’s best to call a professional.
How to Clean Evaporator Coils
The biggest problem with cleaning evaporator coils is that they are often difficult to access without damaging or breaking the fins.
It’s important to always use eye protection.
Also, you need to be patient as evaporator coils can take longer to clean. It’s possible to clean evaporator coils by yourself (I’ve done it successfully after a couple of tries), it’s not shameful to call a professional or someone with experience.
