Cooling Capacity and Output
BTU rating indicates cooling power. For medium to large RVs, 15,000 BTU is ideal to maintain a comfortable temperature. Confirm the unit matches your RV’s square footage for effective cooling.
Ducted vs. Non-Ducted Systems
Ducted units allow distributing cool air through multiple vents, providing balanced room temperatures. Non-ducted setups rely on a single air outlet. Check if the air conditioner supports ducting and if an air distribution box is needed.
Profile Height and Installation
Measure your RV roof opening size and clearance. Standard profile units fit lower rooftops better but may have slightly less airflow compared to high-profile units. Verify mounting compatibility to avoid costly modifications.
Power Requirements
Review the unit’s voltage and amperage needs. Lower amp draw models are advantageous for RVs with limited electrical capacity or those running off generators or solar systems without causing overload.
Noise Levels
Quieter AC units enhance comfort while sleeping or relaxing. Look for noise specifications around or below 60 decibels for peaceful operation during travel or camp stays.
Durability and Weather Resistance
Since RV air conditioners endure road vibrations and exposure to elements, look for units with UV-resistant, corrosion-proof housing and robust build materials like ABS plastic for longevity.
Additional Features
- Blower Speeds: Multiple speeds improve airflow control.
- Overload Protection: Safety feature to prevent electrical damage.
