RV AC Unit Replacement

When your RV rooftop AC unit is beyond repair — whether from compressor failure, repeated breakdowns, or age-related inefficiency — Sun Coast RV Service handles complete unit replacement at your location. No towing to a dealer, no extended wait times. We remove the old unit, install the new one, seal the roof opening, and test everything before we leave.

When Replacement Makes More Sense Than Repair

• Compressor failure on an older unit — If the unit is 10+ years old and the compressor fails, replacement is typically more cost-effective than a compressor swap.
• Multiple recurring failures — When you're facing a third or fourth repair in the same season, a new unit provides reliability and warranty protection.
• Reduced cooling capacity — Older units lose efficiency over time, especially in Florida's demanding climate. A new unit can cool more effectively with less energy.
• Upgraded features — Modern units offer quieter operation, heat pump capability, improved airflow, and better energy efficiency than units from even five years ago.

Brands We Install

We carry and install Dometic Brisk II, Dometic Penguin, Coleman-Mach, and Advent Air units. We'll recommend the right BTU rating and features for your RV size, insulation, and usage patterns. In Florida, we generally recommend heat-pump-equipped units for year-round climate control.

Installation Process

Installation takes 2-4 hours depending on the unit and any modifications needed. We remove the old unit, inspect and repair the roof gasket area, install the new unit with fresh sealant, connect all wiring, and run a complete performance test including temperature differential measurement.
