Efficient Heating and Cooling in One System
Heat pumps are increasingly popular in RVs because they provide both cooling and heating from a single rooftop unit — no propane needed for mild winter days. But when the heating mode fails, the diagnosis requires understanding how the reversing valve and defrost system work.
Common heat pump issues include a stuck reversing valve, bad defrost board, or faulty temperature sensor. Our team diagnoses these efficiently.
