6 Easy Steps To Clean Your RV AC Coils
Although cleaning your RV ac coils is easy as cake, you will need some instructions, along with a few items. And if your AC coils are situated on top of the RV, you need to get a second pair of hands.
The things you will need
- A Screwdriver.
- Soft-bristled brush.
- Fin comb (To straighten coils).
- Coil cleaner (designed for AC coils).
- A spray hose or bucket of water.
Step 1: Turn Off The RVs Circuit Breaker
Start by turning off the circuit breaker. You don’t want the AC coils shocking you when you clean it. And it is also necessary for the AC’s safety as running power might short-circuit it.
Step 2: Remove The AC Coil Cover
Now is the fun part. Start locating your AC cover. It may be on top of your RV on the side, or on the back, depending on your model. A screwdriver will come in handy at this point. Remember to store the screws in a secure place.
Step 3: Brush Away The Dirt From The Coils
Inspect the coils and start brushing off all the dirt. Use a soft bristle brush, as harder ones will damage the coils. If there is grim dirt in the coils or any insect nest, you should clean it with a cleaner.
Step 4: Straighten The Bent Fins
Most of the time the coil fins are not bent. But it is possible for them to go bent over time. A fin comb will help you get them straight. Do not attempt to fix them with a screwdriver or other equipment. It will do worse than any good.
Step 5: Apply Coil Cleaner And Rinse If Necessary
At this point, start doing a thorough cleaning. Mix some coil cleaner in a bucket of water or in a spray can. And spray some on the coils. Do not use a pressure washer, as it will bend and damage the coils. And let it sit for a good 10 minutes. Then rinse off with water. This step is necessary if your AC coils are really dirty and it’s not coming off. Or if there is an insect infestation.
Step 6: Dry The Coils And Put Back The Cover
Let it air dry or use a microfiber cloth to dry off some water off of the coils. After it dried off perfectly, put back the cover, and screw it securely. And then proceed on turning your RV breakers on. And check if your AC is working perfectly.
