For RV owners there are few things that are more comfortable than sitting beneath the cooling shade of an awning in the warm, summer sun. However, RV owners know that as temperatures rise, things can get quite toasty on the inside of their home away from home. Not willing to sacrifice comfort for the freedom of exploring the open road, this presents a challenge for RV owners who want to make their second home as comfortable as their main domicile. This is why we at Mobile RV awnings in San Diego, would like to offer some tips on making your RV as comfortable as it can be on these soon to come warm summer days.


Some Basic Information


You should first know your cooling needs before purchasing an air-conditioner for your RV. Obviously, you don’t want to buy an air-conditioner that is too weak as this will make for many uncomfortable trips in your RV. On the other hand, you don’t want to purchase a more powerful (and thus more expensive) unit than is necessary to cool off your rig. Therefore, before you buy an air-conditioner for your RV, it is a good thing to know how many BTUs you will require. A BTU (British Thermal Unit) is defined in the HVAC industry as the amount of heat needed to raise 1 (one) pound of water by 1(one) degree Fahrenheit. The amount of BTUs you will need from your air-conditioner will depend on the square footage of your RV. For example, a large RV may require an 18,000 BTU air-conditioner. Most air-conditioners will have a chart attached to them so that you can match square feet, room size, etc. with BTUs.


Kinds of RV Air Conditioner Units

Rooftop units are the most common type of RV air-conditioner. This is because many people have discovered that they are particularly efficient at converting the heat in their rig into cooler air. (Remember that heat rises, while cooler air falls.) However, while rooftop units are the most commonly used type of air-conditioner, there are other kinds.


  • Vent Free Portable Air Conditioner: Designed for smaller RVs, these units cool the air by using evaporated water that is released into the dry air. This in turn quickly chills the RV.
  • RV Window Air Conditioner: The advantages to window units are that they are easier to install than rooftop units and are more compact.
  • Portable RV Air Conditioner: This kind of air-conditioner uses hoses and a compressor to cool off an RV. The main disadvantage to this type is that they can take up a lot of space.


Finally, our RV awnings offer great protection from the heat of the sun and its damaging UV rays when you are outside but there is nothing like a functioning air-conditioner to cool off underneath when you are indoors.
