RV Air Conditioners

On a 95-degree afternoon the rooftop A/C is the appliance every RVer watches most, and it pulls hard off a single shore or generator circuit for hours at a stretch. Three separate needs sit under this heading: the rooftop unit itself, the internal parts that wear out, and the covers that keep sun off the housing. Open the child category that matches your situation and skip the other two.

Where to start with RV air conditioning

Most cooling complaints trace back to one of three causes: an aging or undersized unit, a failed internal component like a capacitor or fan motor, or a shroud gone brittle in the sun. Naming the cause tells you which category below to open.

  • RV A/C Units — whole rooftop air conditioners in 13,500 and 15,000 BTU from Coleman-Mach and Dometic, including ducted, non-ducted, quiet, and high-efficiency models.
  • A/C Parts and Filters — the components that actually fail: run and start capacitors, fan motors, condensate pumps, return air grills, filters, and controllers.
  • A/C Covers and Shrouds — replacement shrouds and vinyl covers that shield the unit from UV and weather while it is parked or stored.

If the unit still runs but cools weakly, check parts before buying a new rooftop. A capacitor under twenty dollars clears more no-start and weak-airflow cases than most owners expect.
