Steps to Clean and Check Your RV Air Conditioner
One of the reasons you love the RV life is the fact that you can have some of the comforts of home while you’re out camping. Air conditioning is one of those important amenities. Keeping your rig’s air conditioning system running at its best requires some routine maintenance and regular service checks. While it’s always a good idea to have a professional check the system, there are some steps you can do yourself in between annual maintenance appointments. If you want your AC to keep your RV nice and cool, consider following these steps:
1. Clean the Filters
Your air conditioner has to work twice as hard when the AC filter is clogged. It’s easy to forget about the filter until you find that your air conditioner isn’t running properly. Luckily, swapping out the filter is pretty easy. Typically, the AC filter is located inside your RV under the air distribution bezel. Take it out and see if it is a washable filter or a disposable one. If you can wash it, do so and allow it to completely dry before returning it to the air conditioner. If it is disposable, or if it appears torn or too soiled, replace it. This should be done on a monthly basis.
2. Clean the Evaporator Coils
While the air filter is drying, look for the evaporator coils. If you see any dust accumulated on them, use a vacuum to remove it. Dust buildup on the evaporator coils can eventually damage the entire unit, so this is a crucial step.
3. Clean the Outside Condenser Coils
Next, safely access the roof of your RV to check the outside condenser coils. To find these, remove the cover from the air conditioner unit, carefully removing the screws that hold it in place. This should allow you to see the condenser coils. Use compressed air to blow them off, blowing from the inside out to dislodge debris and avoid having it go back into the air conditioner. Replace the cover and put the screws back into place.
4. Oil the Fan
The AC unit has a fan that keeps air moving, and it needs to be lubricated to work well. Keep it well-oiled by checking it every time you maintain your air conditioner, and you will get the longest possible lifespan from it.
5. Open the Roof Vent
Your RV has a roof vent that needs to be opened from time to time. Doing so will allow moisture that builds up in the system to evaporate. You should open the roof vent periodically during times when you’re enjoying the outdoors and are not using the air conditioner. By letting the moisture evaporate, you can prevent unwanted damage to your air conditioner due to moisture buildup.
6. Clean the Vents
If the AC vents are getting a little grimy, clean them. Leaving the grit in the vents means every time the system runs, you’re breathing in dust mites and other pollutants. Dirty vents that get filthy again quickly after cleaning can indicate you need new ductwork as well because it is often a sign that the ductwork is getting pretty dusty.
7. Cover It
In the off season, make sure you cover the AC unit. This will protect it from unnecessary wear and problems with dust and pests when you’re not actually using it.
Taking care of your RV’s air conditioner is not hard, but it does require some attention and time. By tackling these steps on a regular basis, you can get a long life out of your air conditioner. So the next time you perform your rig’s routine checks, make sure you add your AC to the list.
