RV Heating & Air

Proper RV Heating & Air is an important part of everyone’s RVing experience. Almost all RVs are now equipped with at least one AC/Heating unit, with larger, higher-end models possibly having multiple.

Most Air conditioners are going to be a bit more self-sufficient than other parts, such as an engine or your set of tires. You can usually get away with checking your Air conditioning unit annually, though it’s still worth going over during your pre-trip inspection. While it’s not necessarily mission-critical that your Air conditioning is functioning at peak performance, you’ll certainly miss it if you’re camping on a cold winter night without it, making it basically a necessity depending on your environment.

Inspect the Outside

Starting out, all you’ll need to inspect the outside of your AC unit is a sturdy ladder and climb onto the roof. After ensuring the roof’s stability, you should first check the outside of the plastic cover over your A/C, and make sure the shroud is in good condition. Signs to watch out for include cracks, splits, breakages or any kind of rot. This cover is important to make sure your RV Heating & Air system stays safe, as, in addition to making it look nicer, it also protects your AC against rainwater and precipitation. Without that cover in good shape, your AC’s lifespan will decrease drastically. You should also make sure that no parts of the plastic shroud have been warped or bent by the sun’s UV rays. Over time, this can cause the whole shroud to fall apart entirely.

Check for Leaks

Make sure that the AC unit is securely mounted to the top of your RV.  While you’re outside on your roof, you should also check the rubber gasket in between the AC and the roof. If it’s not properly sealed, you greatly increase the likelihood of water leaking into your RV.

Inspect the Fins

Make sure that the cooling fins are in solid condition as well.  Bent fins can greatly decrease the overall efficiency of the system, and impede air-flow.  If you find that you have bent fins, you should be able to re-bend them into position using a comb or other similar tool.  No matter what you use though, be careful not to penetrate any condenser tubes in your AC Unit.  Puncturing the condenser tubes is a sure-fire way to turn your Air conditioning unit into a hunk of scrap metal.

 

Fortunately, new shrouds can be easily purchased online, and you should, of course, consult your RV’s owner manual to ensure compatibility.

 

Most AC repairs are not nearly as economical as just replacing the shroud and will often require a much more extensive repair procedure from an experienced professional.  RV Heating & Air systems are no exception
