6 Best RV Air Conditioner With Heat Pump in 2026: A Practical RV Guide
Six rooftop RV air conditioners with a built-in heat pump, from 15,000 to 18,000 BTU, compared on cold-weather limits, noise and 115V fit.

A heat pump rooftop unit gives an RV electric heating from the same box that cools, which saves propane and furnace noise on mild nights. What separates one from another is the heating output, the lowest outdoor temperature it works in, and the way it is powered.
This list starts with the TOSOT, the only listing here that gives a heat pump BTU figure and a 43 dB noise level, then moves through three 18,000 BTU units and two COOLIGO 15,000 BTU models.

- Cold-weather limits
- We noted the stated outdoor temperature ranges and defrost features.
- Noise ratings
- We compared dB figures printed on the listings.
- Power connections
- We noted which units need both 115V AC and 12V DC.
- Roof fit
- We compared roof opening sizes and unit dimensions where given.
What Matters Before You Choose an RV Air Conditioner With Heat Pump
Key buying criteria so you get the right fit the first time.
Heat pump versus cooling-only
A heat pump reverses the cooling cycle, so it moves heat into the cabin using far less electricity than a plain heating element. It works best above about freezing and loses capacity as outside air gets colder. Look for the words heat pump plus a stated heating BTU or wattage.
Cooling capacity for your length
BTU is heat moved per hour, and an 18,000 BTU unit suits larger trailers while 15,000 to 16,000 BTU is a better match for mid-size rigs. Too little capacity struggles in desert heat. Match BTU to coach length and insulation.
Outdoor temperature range
Heat pumps lose output as temperatures fall, so the lowest rated outdoor temperature matters. A range starting at 23 degrees F covers most shoulder-season camping but not deep winter. Check the stated range against your coldest nights.
Defrost and cold behavior
Outdoor coils can frost over in cold, damp air, and a defrost cycle clears the ice. Without it, heating output drops over time. Look for an automatic defrost mention on the listing.
Power wiring requirements
Several 18,000 BTU units state they need both 115V AC and 12V DC connections. A missing 12V feed means an extra wiring job on the roof. Read the power notes in the opening lines before ordering.
Noise and airflow figures
A dB rating shows how loud the unit is, and CFM or cubic meters per hour shows how much air it moves. Lower dB with the same airflow is better for sleeping. Compare stated numbers instead of the word quiet.
Match an RV Air Conditioner With Heat Pump to Your RV
By Coach Size
| Your situation | Recommended pick | Why |
|---|---|---|
| 16 to 24 foot trailer, app control | TOSOT 16K Heat Pump | Rated for that length with a stated heat pump BTU. |
| Large trailer or fifth wheel | Arsenda 18K Heat Pump A | 18,000 BTU cooling with 50 dB operation. |
| Second source for the same 18,000 BTU unit | Arsenda 18K Heat Pump B | Same specs and temperature range. |
| Mid-size rig, 20 to 28 feet | COOLIGO 15K Dual-Rotary | 15,000 BTU with a dual-rotary compressor. |
| Older trailer on a tight budget | COOLIGO 15K 1650W | Lowest price with defrost and remote. |
Scroll sideways to see every column.
By Budget
| Budget | Recommended pick |
|---|---|
| $500 to $740 | COOLIGO 15K 1650W or COOLIGO 15K Dual-Rotary |
| $770 to $860 | Tusoma 18K Heat Pump or Arsenda 18K Heat Pump A |
| $850 to $980 | Arsenda 18K Heat Pump B or TOSOT 16K Heat Pump |
Smart Control vs Basic Remote
- Smart control
- WiFi control lets you start the unit before arriving. The TOSOT 16K Heat Pump offers it through the Gree+ app.
- Basic remote
- A remote control covers most daily needs without an app. The Arsenda 18K Heat Pump A, Tusoma 18K Heat Pump and COOLIGO 15K 1650W take this route.
Choose the TOSOT 16K Heat Pump if remote pre-cooling matters; otherwise a remote-only unit is fine.
By Noise Priority
| Preference | Recommended pick |
|---|---|
| Quietest listed dB | TOSOT 16K Heat Pump |
| 50 dB with 18,000 BTU | Arsenda 18K Heat Pump A |
| 50 dB at lower price | Tusoma 18K Heat Pump |
| Compact with R32 | COOLIGO 15K Dual-Rotary |
For Spring and Fall Camping Specifically
- Look for
- Look for a stated heating figure, a low-end outdoor temperature rating and a defrost mention, as the TOSOT 16K Heat Pump listing shows.
- In this comparison
- The TOSOT 16K Heat Pump lists 12,500 BTU heating and a 23 degree F floor, and the COOLIGO 15K 1650W lists defrost.
When to Spend More
- Spend more if
- Spend more if you want a stated heat pump BTU, 43 dB operation and WiFi, which the TOSOT 16K Heat Pump provides, or the extra cooling headroom of the Arsenda 18K Heat Pump A.
- Save if
- Save if you camp in mild weather: the COOLIGO 15K 1650W and Tusoma 18K Heat Pump cost the least of their size classes.
Before You Bring One Home
Is a heat pump AC worth the extra over cooling-only?
If you camp in shoulder seasons, yes, because it replaces furnace use on mild mornings. In freezing weather it will not replace the furnace. Count it as a bonus rather than your main heat.
Does the unit need special wiring?
Several 18,000 BTU listings state they need both 115V AC and 12V DC, so check your roof for a 12V feed. A 115V-only unit like the COOLIGO 15K Dual-Rotary has fewer wires to connect. Read the power note first.
What is the most common mistake?
Assuming the heat pump works as well at 25 degrees F as at 50 degrees F. Output falls as the outside air cools. Keep a space heater or the furnace ready for cold nights.
How do I install a rooftop heat pump?
Remove the old unit, check the 14.25 inch opening and gasket, and seat the new unit on the roof pad. Tighten the mounting bolts evenly from inside and wire it up. Seal with the supplied gasket.
How often should I maintain it?
Clean the filter monthly and rinse the roof coil fins gently each season. Check the roof seal and defrost drain regularly. Cover the unit for winter storage.
