Do-It-Yourself RV Air Conditioner Checks

With the heat of summer, these tips will help keep you cool out on the road.

When it’s hot outside and you’re planning an RV trip to your favorite KOA, the last thing you want is a problem with your RV air conditioner. The good news is it’s not that difficult to test your RV air conditioner’s cooling performance prior to leaving on your trip. Follow along as RV expert Mark Polk shows you how to DIY some simple air conditioner tips.

Top Tips From This Video

• For optimal testing, you want the air temperature around your air conditioning unit to be about 75 degrees
• Prior to testing the unit be sure to check:
  • Power is off to the RV
  • Inspect the filters to see if they are cleaned or damaged
  • Check the fins on the condenser coils to see if they are clean or have obvious damage
• Turn the power to the RV back on to test your air conditioner unit
• Set the AC to high cool and allow it to run for a minimum of 15 minutes with all ducts open
• To test, position the thermometer at the AC return and measure the temperate of the air entering the unit
• Position the thermometer at the closest duct to the unit to measure the conditioned air
• Subtract the two figures to see if the difference falls between a 16 to 22 degree difference in temperature – this range means your unit is operating properly
