RV AC repair and heating service: rooftop AC replacement, capacitor and fan motor swap, furnace ignition repair, heat pump service, soft-start install, thermost
We repair and replace everything on the climate side of your RV coach. That means rooftop AC units (Dometic and Coleman-Mach the most common), furnace ignition boards, heat pump systems, thermostats, and all the electrical guts - capacitors, fan motors, soft-starters, relays. We don't touch chassis engines, transmissions, or appliance venting. If it lives on the roof, in the wall, or mounted to the frame and it controls temperature inside, we handle it. Most rooftop AC replacements run $1,100 to $1,600 depending on BTU and whether you're staying with an air-cooled or going liquid-cooled. Furnace repairs typically cost $250-$800.
A guy rolled in with a 2019 Jayco Greyhawk - Dometic AC compressor iced up, furnace wouldn't kick on in the Idaho cold. We diagnosed a bad soft-start on the AC (failed capacitor bleeding voltage) and a corroded ignition board on the furnace. Replaced both in one visit. That's the real-world mix we see. He got a flat quote over the phone, we showed up mobile, 90-day warranty on both parts. He didn't have to trailer it anywhere or wait three weeks at a dealer service bay.
Services we deliver in-field:





Capacitor failure is the #1 culprit - costs about $150-$300 to replace and kills the AC compressor or fan overnight. Heat pump systems fail when the refrigerant charge drops (slow lea

Soft-start failure after voltage spikes
Capacitor swap: $150-$300. Furnace ignition repair: $300-$600. Full rooftop AC replacement: $1,100-$1,600. Heat pump service: $400-$900. Soft-start install runs $200-$350. Thermostat replacement is $150-$250. We quote flat-

Bad start capacitor or no soft-start kit installed. Fix is a $90 capacitor swap or $300 soft-start.
In our core Florida and Idaho service areas, we aim for 2-4 hour emergency response. We're mobile-only - no shop, no waiting for bay availability, no appointment backlogs. We carry tools and common parts in the truck. If we need a rooftop unit, we'll get it ordered same-day and schedule the install within 48-72 hours. Peak summer (July-August in Florida, June-July in Idaho) we run longer response times because half the RV community needs AC at once - that's when calling early matters. Non-emergency calls (thermostat noise, weak cooling) usually get scheduled within 1-2 weeks. Call (888) 787-3727 with your RV location and problem. We quote flat-rate and confirm availability before committing.
A lady with a 2020 Grand Design Momentum parked in Tampa called us at 2 PM on a Friday in July - AC compressor running but no cold air. We were on-site at 4:15. Diagnosed a failed capacitor and a low refrigerant charge (slow leak from a pinhole in the condenser line). Replaced the capacitor same-day ($220), sealed and recharged the system next morning ($480). She had AC before the weekend got unbearable. A dealership would've put her on a list for Tuesday.
Response time by situation:
We repair Dometic and Coleman-Mach systems - the two brands that ship on 90% of RVs. We also service Atwood furnaces, Lippert soft-starters and slide-out motors (which sometimes affec
We warranty all parts and labor for 90 days. If a capacitor we installed fails in week two, we replace it no charge. If a furnace ignition board we installed doesn't fire up in cold weather a month later, we come back and fix it. The warranty covers defective parts and installation error - not wear-and-tear on surrounding components, not damage from owner misuse, not neglect (like running an AC without refrigerant charge for months). We document every repair with photos and test results so there's no argument about what we did or didn't do. You get a written receipt with the warranty terms spelled out. If you move out of our Florida or Idaho service area, our nationwide partner network honors the labor portion of the warranty.
A customer in Ocala had us replace a Dometic AC unit on a 2017 Coachmen RV. Three weeks later the unit shut down due to low refrigerant (we had sealed it and charged it at install). We came back, traced a micro-leak in the new install (our solder joint), re-sealed it, and recharged it - zero bill. That's what the warranty covers. If he'd run the unit with the fresh air vent open for two weeks and lost charge that way, that'd be on him.
