Blowing Warm Air
The fan runs but the cabin stays warm, often a weak capacitor or a dirty coil after weeks of humid weather.
Rooftop AC diagnosis for muggy Hampton Roads summers
RV AC repair in Virginia Beach gets busy once the summer humidity settles in and rooftop units start running all afternoon. If yours blows warm, trips the breaker, ices over, or drips water inside, we come to your campsite, driveway, or storage lot, test the unit, and many repairs are completed in a single visit.

The fan runs but the cabin stays warm, often a weak capacitor or a dirty coil after weeks of humid weather.
Humid air means more condensate, and a clogged drain pan or worn gasket sends it through the ceiling.
The unit shuts down as the compressor kicks on, a sign of a failing start capacitor or low pedestal voltage.
Ice on the coil usually means restricted airflow from a dirty filter or a slowing fan motor.
Rattling or grinding overhead points to a loose shroud, worn fan bearings, or a struggling compressor.
Summer air in Hampton Roads is heavy with moisture, so a rooftop unit has to pull water out of the air as well as cool it. That extra work runs compressors longer, heats up capacitors, and fills drain pans faster. Add salt air on the outdoor coil, and units near the water tend to lose cooling capacity sooner than inland ones.
Every RV AC call starts at the unit, not the parts bin. We check voltage while it starts, test the run and start capacitors, measure fan motor draw, and inspect the coil, filter, drain pan, and ducts. We service Dometic, Coleman-Mach, and Furrion units, ducted and non-ducted. Power trouble at the pedestal or breaker panel often ties into RV Electrical Repair, and water around the unit's base points to the gasket and sealant work in RV Roof Repair. It's part of our Virginia Beach mobile RV repair, whether your trailer is at a campsite near Sandbridge or in a Kempsville driveway.

In humid weather the unit pulls a lot of water out of the air, and that water has to drain off the roof. If the drain pan is clogged or the gasket under the unit has flattened, it finds its way through the ceiling grille instead. We clear the drain, check the gasket, and reseal if needed.
It depends on the size of the RV, how much sun it gets, and the unit's condition. A healthy 13,500 or 15,000 BTU unit can keep a mid-size trailer comfortable, but a weak capacitor or dirty coil cuts output noticeably. Parking in shade and keeping the vents clear helps too.
Yes, along with Furrion and most other rooftop brands, ducted and non-ducted. Tell us the brand and model when you call (757) 540-0095, and we'll plan for the parts that unit usually needs.
