Best RV air conditioner What makes the best RV air conditioner? We know the drill : its summer, you’re driving or resting, couldn’t find a parking space in the shade and then… your RV is hell on earth, a hot and steamy inferno. Well, fear not, traveler, there are excellent options of a great air conditioning within your favorite vehicle at hand. At the Air Geeks, during our tests, we asked ourselves : what criteria make a great RV AC unit? In our mind, the best air conditioner for an RV has to have the following qualities : Easy-to-install : RV parts are tricky enough to function together – we don’t want to add to the compexity, especially when it comes to AC units. Light : your RV roof is not a place where you want to add weight. You want to kep it light and compact to avoid increasing your gas consumption Very efficient : an RV is a relatively small space, but it is not well insulated. A great RV air conditioner has to have the power to cool down an RV space in a few minutes, while not draw heavily on your resources.
