An RV AC that runs but blows warm air is one of the most common summer service calls we get in the Apopka area. July and August temperatures make this a true emergency - a Class A motorhome with a failed AC can reach dangerous interior temperatures within an hour of losing cooling in direct Florida sun.

The three most common causes of a running-but-not-cooling RV AC are a failed start or run capacitor (by far the most common and cheapest fix), extremely dirty evaporator or condenser coils reducing heat transfer efficiency, and low refrigerant - though truly low refrigerant is less common than most owners assume because modern RV AC units are sealed systems.

Diagnosing RV AC That Runs But Doesn't Cool

We start by measuring the temperature differential between the air entering the AC and the air coming out of the vents. A properly functioning AC should produce a 15 to 20 degree Fahrenheit temperature drop. Less than 10 degrees indicates a serious problem. We then check the amp draw on the compressor and fan motors - a failing capacitor shows a characteristic amp pattern that's easy to identify with a clamp meter.

How We Fix It

Capacitor replacement - most common fix, 45 minutes on-site, $185 to $225 typical cost
Coil cleaning - evaporator and condenser coil cleaning with appropriate cleaner restores heat transfer
Fan motor replacement - when the condenser fan fails the compressor overheats and shuts down on thermal protection
Thermostat replacement - less common but a failed thermostat can prevent the compressor from engaging at all

FAQ

Common Questions

Can an RV AC freeze up in Florida?

Yes. Paradoxically, a dirty evaporator coil or low airflow can cause the coil to ice over in Florida humidity, completely blocking air flow. The fix is cleaning the coil and improving airflow - often by cleaning or replacing the return air filter.

How do I know if my RV AC capacitor is bad?

A bad capacitor often causes the AC to hum without fully starting, start then immediately shut off, or run the fan normally but the compressor won't engage. A technician can confirm with a capacitor tester in about 5 minutes.

Is it worth recharging RV AC refrigerant?

RV AC units are sealed systems and should not need refrigerant unless there's a leak. If someone tells you to recharge an RV AC without finding a leak first, that's a diagnostic shortcut. We find the root cause before recommending any refrigerant work.

What is the average lifespan of an RV rooftop AC?

10 to 15 years with proper maintenance. In Florida's harsh UV environment and high summer workload, 10 to 12 years is more realistic. Annual coil cleaning significantly extends service life.
