Buying Guide — Key Considerations For Choosing An RV Roof A/C
- Rooftop space and mounting: Measure roof opening and confirm compatibility with ducted vs non-ducted configurations.
- Cooling capacity vs. RV size: Larger spaces benefit from higher BTU ratings; smaller campers can prioritize efficiency and weight.
- Power and energy use: Off-grid setups benefit from variable-speed models and energy-efficient units; verify AC power (115V) compatibility with your electrical system.
- Noise and comfort: Look for units with noise levels around 50-55 dB for comfortable living space.
- Installation complexity: Some units require professional installation or specific accessory kits (ADB, distribution boxes); consider your DIY comfort level.
- Maintenance and durability: Evaluate shell material and gasket design to resist weather and UV exposure over time.
FAQ
- What BTU level is right for my RV?
Base the choice on RV size and insulation. Typical mid-size RVs do well with 13,500–15,000 BTU units; larger rigs may require 18,000 BTU or higher, especially in extreme heat.
- Should I choose ducted or non-ducted RV AC?
Ducted systems distribute air more evenly in larger interiors. Non-ducted units are simpler to install and fit smaller or rigid RV layouts.
- Can I install an RV AC on my own?
Some models offer bolt-on installation with guides; others require professional installation, electrical work, and rooftop reinforcement. Check the unit’s installation documentation.
- What refrigerant types are common?
R32 refrigerant is widely used for efficiency and lower environmental impact; confirm refrigerant type with the specific model.
- Will a higher BTU unit drain my battery faster?
Yes, higher BTU operation can draw more power. Look for units with variable speed or energy-saving modes to balance cooling and battery life.
- Are all units suitable for rooftop mounting on any RV?
No. Roof structure, vent openings, and weight limits vary. Verify compatibility with your RV model and roof rating.
