RV A/C Replacement in San Diego
A/C isn’t a luxury on a summer road trip — it’s a necessity. If your unit isn’t cooling your rig the way it should, it may be time for a replacement. San Diego RV Center can swap out your A/C unit faster than the other shops in town, getting you back on the road and out of the heat before your next trip.
An RV A/C system won’t last forever, but with proper use it should give you several solid years. Here in San Diego, summer heat and heavy use can wear a unit down faster than you’d expect. Don’t wait until it fails completely — if it’s struggling to keep up, bring it in and let our team take a look.
We recommend and install the industry’s leading brands:
- Dometic RV air conditioners
- Coleman (Coleman-Mach) RV air conditioners
- AirXcel HVAC solutions, including MaxxAir roof vents
- Rooftop and ducted A/C replacement
- Gasket and thermostat replacement
If your unit can be saved, ask about A/C service under our general RV repair. Regular maintenance helps your A/C last longer.
Conveniently located off Interstate 8 in El Cajon, we serve RV owners across San Diego, El Cajon, La Mesa, Santee, Lakeside, Spring Valley, and Lemon Grove.

RV A/C Replacement FAQs
How much does RV A/C replacement cost?
Cost depends on the unit and whether it’s rooftop or ducted, but a new RV A/C unit plus installation is generally a few hundred to over a thousand dollars. We’ll quote your exact unit before any work begins.
Should I repair or replace my RV air conditioner?
If the unit is older, struggling to cool, or has a failed compressor, replacement is usually more cost-effective. If it’s a capacitor, gasket, or thermostat, a repair may do. We’ll tell you honestly which makes sense.
What RV A/C brands do you install?
We install Dometic, Coleman (Coleman-Mach), and AirXcel/MaxxAir products — the industry-leading brands we trust for San Diego heat.
How long does A/C replacement take?
Most rooftop A/C replacements are completed the same day or next day. We move quickly because we know you don’t want to wait out the heat.
Why isn’t my RV A/C cooling?
Common causes include a frozen coil from a dirty filter or low refrigerant, a failed capacitor or compressor, a wiring fault, or a dried-out roof gasket letting warm air in. Bring it in for a diagnostic.
