RV AC Units - Relief from Summer Heat

RV AC units are found on almost all new travel trailers, fifth wheel campers, toy haulers, and motorhomes. No one wants to suffer in the summer months and swamp coolers are generally only found on less expensive RVs anymore. A swamp cooler can work great but when you are in the hottest climates, a regular RV air conditioner does a much better job of keeping an RV cool.

RV AC UnitsUse Your A/C Efficiently

Whether your RV will stay cool in the summer is dependent upon a couple of factors. The output of your air conditioner is the first consideration. AC output is measured in BTUs (British Thermal Units) or tons.  You can use either figure to get a grasp on the cooling capacity because they are essentially the same. All you need to know is that there are 12,000 BTUs in a ton. The second thing to take into account is how large the volume of your RV is. If you have a big RV and there a lot of cubic feet to cool, you may need two air conditioners to keep your RV cool. However, if you have doors between the different rooms in your RV, you can just close doors and only run the air conditioner that services the room(s) that you are using. The other factor that is really important in all of this is the degree to which your RV is insulated. Unfortunately, there is little you can do improve the insulation of your RV after the fact, but if the insulation is minimal, your air conditioner will be running frequently because the heat outside will warm your RV more quickly.
In an effort to help reduce our consumption of electricity, the federal government mandated by law that the companies manufacturing air conditioners for residential use had to build more efficient air conditioners. These newer air conditioners are a lot more expensive, but they do use a lot less electricity. The good news is that some of the new technology that was developed to make AC units more efficient is finding its way into the RV market. This will mean that for those people that rely heavily on shore power, their electric bills should drop when they install a new unit. Of course, utility companies are always raising their rates, so the savings may not be great but at least you won’t be paying more for a while. For the folks that like to boondock and camp in places where there is no shore power, the comfort provided by an air conditioning unit has not been feasible because of the amount of electricity drawn by an air conditioner. However, for the person that has installed a large number of RV solar panels on their RV feeding a big battery bank, they now may be able to use air conditioning if they have installed a really efficient air conditioner. Lots of boondockers seem to like the desert environments so this could be a real breakthrough.

How to prevent this in the future? Get the heck “out of Dodge” when a hurricane is approaching! Seriously though, if the RV is not being used at the time, you can purchase a cover for it that will minimize the intrusion of rainwater through the ventilation openings in the shroud. If you’re living in the rig at the time, and the wind and rain are blowing sideways, just be sure the drain holes in the pan of the air conditioner are free and clear so the incoming water can drain onto the roof before it has a chance to seep into the living area.
