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

California’s intense solar radiation and warm conditions impose heavy loads on RV rooftop AC systems fitted to the roof of RVs. Motorhomes stationed in full sun or traveling across interior valleys frequently lose cooling effectiveness as heat buildup overwhelms system performance. Dust particles, road grit, pollen, and airborne contaminants rapidly build up on condenser and evaporator coils, impeding heat dissipation and leading to merely lukewarm or warm discharge. Progressive refrigerant drop via tiny leaks or material permeation lowers pressure levels, compelling the compressor to operate longer without producing adequate chilled air.
