Buying Guide For RV Air Conditioners

What You Need to Know Before Buying an RV Air Conditioner

When you’re on the road in summer, a reliable RV air conditioner can make the difference between a miserable trip and a comfortable adventure. RV-specific AC units are designed to handle mobile environments, compact spaces, and the unique power constraints of recreational vehicles. Some points to consider when choosing your unit:

BTU Rating- Determines cooling power; larger RVs and hotter climates require higher BTUs (13,500–15,000 BTU is common).

RV Size - Match the unit’s capacity to your RV’s square footage and layout.

Ducted vs.Non-Ducted - Ducted systems distribute air through vents; non-ducted units blow air directly into the cabin.

Power Requirements - Most rooftop units run on 115V–120V shore power; confirm compatibility with your setup.

Heat Pump Option - Provides both cooling and supplemental heating for extended-season camping.
