RV air conditioners make hot-weather camping comfortable, cooling your interior and controlling humidity. Rooftop units are most common, mounting in a standard 14x14-inch roof opening and distributing cooled air through the ceiling or ductwork. Understanding BTU capacity, power requirements, and your RV's capabilities helps you choose the right cooling solution.

What to Know Before You Buy

• BTU capacity should match your RV's size and insulation—13,500 BTU handles smaller spaces; 15,000 BTU suits larger rigs.
• Power draw matters: Most rooftop AC units require 15-20 amps of 120V power; running two units usually requires 50-amp service.
• Low-profile units reduce wind resistance and overall height; standard units are easier to service and often more powerful.
• Heat pump models provide heating as well as cooling—useful in mild weather but less effective in extreme cold.
