Rooftop Unit Diagnostics
Because most rooftop RV ACs are hermetically sealed units, typical failures involve complex electrical breakdowns rather than simple refrigerant leaks. Anaheim AC Repair Pros provides full-lifecycle support for motorhome cooling, utilizing advanced multi-meters and diagnostic tools to pinpoint voltage drops, seized blower motors, and failed control boards on major brands like Dometic, Furrion, and Coleman-Mach.
As fully certified technicians, we maintain strict safety protocols when dealing with 120V AC shore power and 12V DC thermostat systems, guaranteeing safe, reliable, and compliant service right at your campsite.

Frequently Asked Questions
Can I run my RV AC off battery power?
Typically, no. Rooftop AC units require 120V AC power. Unless you have a massive lithium battery bank paired with a heavy-duty inverter (3000W+), you need to be plugged into shore power or running a generator.
What size generator do I need to run a 15k BTU AC?
A standard 15k BTU RV air conditioner needs about 3,300 to 3,500 starting watts and around 1,500 running watts. A 3500W to 4000W inverter generator is highly recommended to handle the initial compressor surge without tripping.
Why is water dripping inside my RV from the AC?
If water is dripping inside the cabin instead of draining off the roof, the evaporator coils may be freezing up due to poor airflow, or the unit's mounting gasket has compressed or torn, allowing rain and condensation to leak through the roof opening.
