RV air conditioner repair in Salt Lake City is complicated by the 4,226-foot elevation, which reduces cooling capacity and stresses compressors. We diagnose and repair Dometic, Coleman, and Advent rooftop units, ducted systems, and mini-splits, with most repairs completed same day.
At 4,226 feet, air is thinner and an AC unit works harder to move the same heat out of a coach. Compressors and capacitors that might last eight years near sea level often fail in five or six in the Salt Lake valley, especially on rigs parked through the summer. Valley temperatures regularly hit 100 degrees in July and August, adding to the load. A capacitor failure is the most common result and it is one of the cheaper fixes, usually $150 to $250 including the service call.
We test starting and run capacitors, check refrigerant pressure using altitude-corrected specs, inspect the condenser coil for debris and the evaporator for ice buildup, and verify the control board is sending the right signals. If the unit is low on refrigerant we identify where it is losing charge before adding more, because a recharge that ignores a slow leak just delays the next failure. The diagnostic fee applies toward the repair if you proceed on the same visit.
Many of our AC calls come from rigs staged near the I-15 interchange heading south toward St. George or parked at campgrounds west of downtown before a Bonneville Salt Flats run. If your AC quits at a campsite within Salt Lake City or West Valley City, the mobile unit can reach you same day. KOA Salt Lake City near the airport and the campgrounds along West 2100 South are in our regular route.
$150 to $800 depending on whether the job is a capacitor swap, refrigerant top-off, or full unit replacement
A unit that trips the breaker, runs but blows warm air, or makes grinding noise usually needs a repair rather than a replacement. Units over 10 to 12 years old that fail on the compressor often cost less to replace than rebuild. We give you both options and the pricing for each before you decide.
Most residential-style rooftop units are sealed systems that should not need refrigerant. If a unit is low, there is a leak. We pressure-test to find the source, repair it, and then recharge to altitude-corrected specs. Recharging without fixing the leak is a temporary fix only.
Ice on the evaporator coil usually means the unit is low on refrigerant, the filter is clogged, or airflow is blocked. Let the ice melt fully, clean the filter, and run the fan-only mode for 30 minutes before restarting cooling. If the problem returns, call for a diagnostic.
A capacitor swap or thermostat replacement takes one to two hours on site. A full rooftop unit replacement takes three to five hours because of the roof access and wiring. We tell you the estimated time when we quote the job.
We run an RV repair operation serving Salt Lake City and the Wasatch Front. We work on motorhomes, fifth wheels, travel trailers, and pop-ups. Utah altitude and high-desert conditions are hard on AC units, water systems, and roof membranes. We give you a written price before any work begins and test everything before we leave the job.
