RV Air Conditioner
Start by removing the filter from the unit. This is usually accomplished by the removal of a few screws or turn bolts around the frame of the filter. If you have a central vac system the job is easy. Just vacume out the filter from both sides. Also vacume the outlet openings on all sides of the unit to remove dust and dirt. While you have the filter out you can also inspect the cooling fins on the upper unit. You may need a flashlight to see them well enough to clean them if necessary. Use caution when vacuming these fins. They will bend easily. Don’t just jamb the end of the vacume into the area. Keep a little distance from the end of the vacume to the fins and just let the vacume do the work. You don’t want to scrub the fins. Just let the vacume remove any dust and dirt accumulations. Just that little bit of maintenance can help keep your RV air conditioner flowing freely and efficiently. You can also climb to the roof and blow out the unit with compressed air from above from time to time as well, but this is not as critical as keeping the inside filters clean.
RV Air Conditioner – Alternative Type
If you are going to spend a lot of time in low humidity climates you might consider adding an evaporative cooler unit to your RV. One such unit, the TurboKool, can usually be mounted in the same 14″ x 14″ openings used by one of your exhaust fan units. These little units are very efficient, bringing cool air with very little power and require only a small 1/4″ water line that supplies the 2-4 gallons of water per day used to cool the air. They operate on 12V power using only 4-5 watts. Most can also be fitted with a reversing switch that allows them to exhaust, just like the exhaust fan you are replacing it with. It’s a great way to stay cool without being connected to shore power or using the generator. This type of unit is also great for boondocking in low humidity climates of the desert southwest or mountain valleys of the west. They do use a little of water so that might be a consideration if you are going to be boondocking for an extended time. These little “swamp coolers” seem to be efficient in humidity levels of below 75%. Above that, in the humidity of the southeast or mid west, just turn on your regular AC unit. Swamp coolers are the preferred type of unit where climates allow them to work efficiently, being used in thousands of homes across the west.
These units are very low maintenance and only require draining, a little cleaning of the fiber mats, and a flush of the water lines before you put them away for the winter.
Whether your regular condenser type air conditioner or a swamp cooler type, your RV Air Conditioner will work hard to keep you confortable. Just a little effort on your part will help to make that job much easier for the units.
