RV Air Conditioning Repair in Tucson, AZ
A rooftop A/C that's blowing warm air isn't optional to fix in a Tucson summer. Shawn diagnoses and repairs rooftop RV air conditioners on-site — and installs mini-split A/C upgrades for RVs and park models that need more cooling capacity than the factory unit can deliver.
Rooftop RV air conditioners take a beating from road vibration, UV exposure, and — in Tucson specifically — ambient temperatures that push the unit's compressor and capacitor harder than they were designed for. The most common failure isn't a refrigerant leak; it's a weak start capacitor or a fan motor that's seized from dust and heat, both of which are same-visit repairs.
For rigs where the factory rooftop unit simply can't keep up — a common problem on older units or during peak Tucson summer — Shawn also installs mini-split A/C systems as a capacity upgrade, sized to the RV or park model's actual square footage rather than a one-size-fits-all swap.
Installing a rooftop air conditioning unit on a trailerIs this what's happening to your RV?
Blows air but it's not cold
Often a failed start/run capacitor or a low refrigerant charge from a slow leak — both diagnosable on-site.
Unit is loud, rattling, or cycling on and off
A short-cycling or rattling A/C usually points to a failing fan motor, a bad capacitor, or a control board fault.
Existing unit can't keep up on 100°F+ days
If a healthy, working A/C still can't hold temperature on Tucson's hottest days, that's a capacity problem, not a repair — a mini-split upgrade is usually the fix.

Frequently asked questions
Most repairs — capacitor, fan motor, control board, thermostat — are done in place on the roof. Full unit replacement is the only time it comes off.
A mini-split adds a separate, higher-capacity cooling system to an RV or park model, usually because the factory rooftop unit(s) can't keep up with Tucson's peak summer heat. Shawn can tell you during a visit whether your existing unit is failing or simply undersized.
