RV Air Conditioners with Heat Pump

What does a heat pump RV air conditioner actually do?

A heat pump RV air conditioner cools in summer and reverses the refrigeration cycle to provide supplemental heat in milder weather, typically down to outdoor temperatures around 40°F. Below that threshold the heat pump loses efficiency and you will need to switch to your furnace or an electric space heater. Think of the heat pump function as a way to take the chill off shoulder-season mornings and evenings on shore power without burning propane.

How many BTUs do I need for my RV?

Sizing depends on rig length, insulation, and climate. As a working rule: 13,500 BTU units cool most travel trailers and smaller fifth wheels up to about 30 feet, while 15,000 BTU units are the right call for larger fifth wheels, motorhomes, or anyone parked regularly in hot climates. For rigs over 35 feet or floor plans with rear bedrooms, a dual-AC setup is usually the better answer. If you want to reduce compressor startup load on a 30-amp service, pair your unit with a soft start kit from our Coleman RV air conditioner soft start collection.

Do I need a ducted or non-ducted ceiling assembly?

Match the ceiling assembly to your RV's existing ductwork. If your rig has air distribution running through the ceiling to multiple registers, you need a ducted assembly. If air discharges directly from a single ceiling grille below the AC, you need a non-ducted assembly. The rooftop unit itself is often the same SKU, but the indoor air distribution box is different. Two common matches: the FreshJet 5 with heat pump non-ducted ceiling assembly and the Coleman Power Saver HP ducted ceiling assembly.

Will a heat pump AC run on 30-amp shore power?

Yes, a single 13,500 or 15,000 BTU heat pump unit will run on a 30-amp pedestal, but you need to manage other loads carefully. Running the AC, microwave, and water heater on electric at the same time will trip the breaker. A soft start kit cuts startup inrush current by roughly 75%, which also makes the unit easier to run on a smaller generator or off a 20-amp adapter in a pinch. For adapter options, see our RV plug adapters collection.

Can I replace my existing AC with a heat pump model?

In most cases, yes. The standard RV roof opening is 14 inches by 14 inches, which fits Dometic, Coleman, Furrion, and Advent units interchangeably at the roof. What changes is the thermostat and wiring. Heat pump models require a compatible thermostat with a heat pump mode and the correct number of control wires running from the ceiling assembly to the rooftop unit. Confirm your existing thermostat is heat-pump capable or plan to replace it as part of the install. Always verify your model number and roof opening before ordering.

What is the lowest outdoor temperature a heat pump will work at?

Most RV heat pump air conditioners produce useful heat down to about 40°F outdoor ambient. Below that, the outdoor coil cannot pull enough heat from the air, and the system will either run inefficiently or default to its cooling lockout. For boondocking in cold weather or winter use, plan on running your propane furnace as the primary heat source and use the heat pump for shoulder-season mornings, evenings, and mild days on shore power.

How is shipping handled on rooftop air conditioner units?

Rooftop AC units ship via truck freight due to size and weight, typically with a flat $99 freight charge depending on the unit. Smaller parts and ceiling assemblies ship standard ground. Inspect the freight pallet before signing for delivery: note any visible damage to the shroud or base pan on the delivery receipt, since concealed freight damage is difficult to claim after acceptance.
