Best 15,000 BTU RV Air Conditioners Ranked

21 rooftop air conditioners over 14,000 BTU for big rigs and hot climates.

Last updated: November 2, 2026

A 15,000 BTU unit is for long trailers, fifth wheels and motorhomes, or any RV that spends summer in the desert or the South. It draws the most current, so on a 30 A hookup it leaves little for anything else, and starting one on a generator usually needs a soft start.

Prices were last checked November 2, 2026 and are subject to change; the price and availability shown by the retailer at the time of purchase apply.
