How RV AC Units Work

RV AC units operate through a rooftop-mounted system that combines an evaporator compressor and condenser in one compact unit. The system pulls warm air from your RV’s interior circulates it through refrigerant-filled coils then releases cooled air through ceiling vents. Most units operate at 13500-15000 BTU and run on 120V AC power drawing between 12-16 amps when cycling. The thermostat controls the cooling cycle by monitoring interior temperature and activating the compressor as needed.

Common Energy Efficiency Challenges

RV air conditioners face unique efficiency hurdles that impact their performance and energy consumption. Direct sun exposure on the rooftop unit can reduce cooling efficiency by up to 30%. Limited insulation in RV walls and windows creates significant heat gain requiring more frequent AC cycling. Power limitations at campgrounds often restrict AC operation to single-unit use even in dual-system RVs. System voltage fluctuations from generator or shore power can cause performance issues reducing overall cooling capacity and increasing energy usage.
