Renogy 3-in-1 15K Heat Pump
A low-priced 15,000 BTU heat pump for non-ducted trailers, from a brand better known for solar gear.

Nearly every RV, travel trailer and motorhome cools with a rooftop unit that drops into the standard 14 x 14 in roof vent opening, so swapping one brand for another is usually a few hours on the roof. These rankings compare what the makers publish on the same terms: how much cooling you get for the money, how many amps it pulls while running, how big a surge it needs to start, how loud it is and how long it’s covered.
Size comes first. A 13,500 BTU unit cools most travel trailers; 15,000 BTU suits long trailers, fifth wheels and hot climates, and units under 12,000 BTU fit vans and small campers.
Amps matter more in an RV than at home. A 30 A hookup or a 2,000 to 3,500 W generator has to carry the air conditioner’s running current and its start surge, so a unit with a soft start or an inverter compressor can run where another trips the breaker.
Ducted or non-ducted depends on your RV’s ceiling. A ducted unit feeds vents built into the ceiling; a non-ducted unit blows straight down through its own ceiling assembly. Check which one your RV has before you buy.
