Duo Therm RV Air Conditioner – Read This Before Buying or Fixing

Traveling in comfort is a top priority for RV users, and anyone spending an extended period of time on the road for that matter.

But it’s especially important to consider the unique needs of a larger RV or trailer when dealing with air conditioning units. Find out what kind of options are out there for RV AC units and how to fix them when something goes wrong.

RV Air Conditioners

Unlike the old window shaker in your first apartment, Duo Therm RV air conditioners are sleek and unassuming by comparison. Your standard unit sits on top of the RV’s roof and pumps cool air into the RV through a square hole, just over a foot in length. From the outside, the units are aerodynamic and low profile. Most come in white or another neutral color. You can purchase replacement shrouds if yours is broken or to upgrade the look and feel of your unit.

RV Air Conditioner parts

Your duo therm RV air conditioner will come with a few parts, most important of which is the actual duo therm RV air conditioner itself. These units range in cost but are typically about $500 to $800.

You’ll have to purchase a separate vent and control unit, which will control the flow of air and the power switch to the unit. Additionally, any type of air grille or filter is sold separately. If you’re installing a duo therm unit for the first time, you might need to look into a gasket kit, which will affix the unit to the roof of the RV if you are installing one for the first time.

If you want to protect your exposed duo therm RV air conditioner from the elements, consider a cover. Most are made out of vinyl and can keep your RV warmer on days when the unit is not in use. Covers also protect the unit from UV rays and from contaminants when it is not being used. Be sure to remove these covers when turning the unit on.

Within the duo therm RV air conditioner itself, you have a fan, a motor unit, and a blower wheel. Replacement parts and cleaning kits are sold to service each of these. Aside from that, rewiring of your unit might be a job for the professionals depending on your skill set.

Troubleshooting Duo Therm RV Air Conditioners

Depending on the time of year, a problem with your duo therm RV air conditioner can be an actual emergency. Learning how to troubleshoot common problems can help you fix a dire situation quickly, and might even save you some money.

As mentioned before, your main interior parts include a fan, motor unit and blower wheel. If you’re experiencing low airflow, you might have a problem with one of these features. Check for any animal nests that might be in the unit from the outside of the RV. Make sure all vents are clear and the filters are clean.

Another common problem with units is the power supply. Be sure your power is live and the source is working. Then make sure your breakers are on. If you have insufficient power for your unit or multiple units, you might not be able to serve your unit. You’ll need at least 30 amps per unit; anything less can damage your AC compressor. And if your unit is new, you might not be able to run it alongside your other appliances such as your microwave, at the same time.

It can be hard to admit, but sometimes a problem with your duo therm RV air conditioner can be chalked up to user error. Make sure you know how to operate your unit before assuming it’s broken. And as always, consult your manual for specific problems regarding your unit.
