Why Is My RV AC Not Cooling Properly in California's Heat?

California’s powerful sunlight and elevated ambient temperatures impose heavy loads on RV rooftop AC units mounted on motorhomes. Vehicles parked under direct exposure or moving through inland valleys frequently lose cooling effectiveness as heat buildup overwhelms system performance. Dust particles, road grit, pollen, and airborne contaminants quickly accumulate on condenser and evaporator coils, restricting heat rejection and resulting in only lukewarm or warm airflow. Progressive refrigerant drop via tiny leaks or material permeation lowers pressure levels, forcing the compressor to run extended periods without generating sufficient cold air.
