Rooftop RV air conditioners mount in a standard 14x14-inch roof opening and cool your rig through ceiling vents or a ducted system. Matching BTU capacity to your floor plan and knowing your shore power limits are the two decisions that matter most. Free shipping on most orders $99+ (US lower 48).
Most rooftop units are a straightforward swap if your existing roof opening is the standard 14x14 inches. You will need to disconnect shore power, remove the old shroud and unit from the roof, drop the ceiling assembly inside, and reverse the process with the new unit. Having a second person on the roof makes it significantly safer.
The most common causes are a dirty air filter restricting airflow, low voltage from an undersized generator or long extension cord, or a refrigerant issue requiring a technician. Start by cleaning or replacing the filter and checking that your voltage at the AC is at least 105V under load.
A soft-start (or compressor start assist) device reduces the startup amp surge from roughly 60-80 amps down to 20-30 amps, which allows many 2000W and 3000W inverter generators to run a rooftop AC. It is also a smart addition if you frequently camp on 30-amp pedestals with older wiring.
