Factory dash AC struggles to cool a long Sprinter, so many owners add a rooftop unit for the rear cabin. We install and service roof AC units, sealing the mount, wiring the power correctly, and repairing units that leak or will not cool, so the back stays livable in Riverside summer heat.
What this service includes
- Plan the mount location and power source for the unit
- Cut, mount, and seal the rooftop AC to prevent leaks
- Wire the unit with proper fusing and controls
- Diagnose and repair existing units that will not cool
Signs your Sprinter needs it
- The rear cabin stays hot while the dash vents are cold
- An existing roof unit leaks water or will not run
- You need cooling while parked for camping or work
What does roof ac installation and repair cost?
Ballpark pricing for roof ac installation and repair on a Sprinter runs $750 to $4,500. The final number depends on your model, mileage, and the exact cause, which we confirm with Xentry before any work is authorized. Diagnostic time is credited toward the repair. See the full pricing page.
Frequently asked questions
Will a roof AC leak into my Sprinter?
Not when the mount is sealed correctly. A poor install is the usual cause of leaks, so we prepare the opening, seal the gasket properly, and check the roof so water stays out through Riverside storms.
Can a rooftop AC run without the engine on?
It can when it is wired to a suitable battery bank or shore power, which is common on camper builds. We size the power source and wiring so the unit runs the way you intend while parked.
