Buying Guide: Roof Unit Air Conditioners For RVs
How to choose the right roof-mounted AC for an RV:
- Vehicle size and space: Match BTU to the RV’s interior area. Larger spaces need higher BTU units to achieve comfortable cooling quickly.
- Non-ducted vs. ducted: Non-ducted roof units are easier to install and ideal for many RVs; ducted systems require compatible ducts and may offer even cooling distribution in larger vehicles.
- Power and energy use: Inverter compressors save energy and reduce peak power draw, which matters for battery and generator setups.
- Climate versatility: Look for units with cooling, heating, and fan/dry modes if year-round use is desired.
- Noise levels: Quiet operation improves comfort on long trips; check dB ratings if available.
- Installation considerations: Check rooftop vent size compatibility (14.25 x 14.25 inches is common) and weight support on your RV roof.
- Maintenance: Consider ease of access for filter cleaning and basic servicing, especially for off-grid travel.
