We don’t stack surprise fees. After-hours add $69. Credit cards accepted. If we can’t fix it, you only pay the diagnostic.
The most common RV AC failures we fix fast
We see the same five failures again and again in Port St Lucie summer heat. First, failed capacitors. You’ll hear a hum, fan may spin, but no compressor start. Second, dirty evaporator or condenser coils choking airflow. Third, low voltage from weak batteries or undersized shore power. Fourth, bad fan motors, usually noisy for weeks before they quit. Fifth, control board faults after lightning or shore power surges. Sound familiar? We carry parts for all five. And we test voltage and airflow, so the fix actually sticks.
Brands we stock: Dometic, Coleman-Mach, Furrion
We service every brand, but we stock parts for the big three so same visit repairs are likely. We keep Dometic Brisk II capacitors and boards, Coleman-Mach fan motors and start kits, and Furrion thermostat modules. According to Dometic’s service guidance for Brisk II units, proper airflow across clean coils is non-negotiable for efficiency and compressor life. That tracks with what we see. We’ll cite model and serial numbers on your invoice for your records.

How we diagnose your RV AC in 45-75 minutes
We start with your complaint and a quick history. Then we meter incoming voltage at the pedestal, transfer switch, and inside at the AC feed. Next, we megger or continuity test the compressor windings if needed, check capacitors under load, and test the fan motor amp draw. We remove the shroud, inspect coils, and measure temperature drop across the evaporator. If your ductwork is crushed or the foam plenum is gapped, we correct it. Bottom line: we confirm the root cause before we quote.

Real jobs we handled this month in Port St Lucie
Last week in Tradition, a 2016 Jayco had no cool on a 94-degree day. Humming compressor, fan running. Bad 45/5 capacitor. We swapped it, added a soft start at the owner’s request, and logged a 20-degree supply drop in 30 minutes. Took 55 minutes door to door. Two days later near Clover Park, a Coleman-Mach fan motor seized. We replaced the motor and blade, cleaned the coils, and sealed a plenum leak. Night and day difference. Customer said, “Should’ve called first, I spent two days sweating.” We hear that a lot.
Same day or after-hours service across the Treasure Coast
We cover Port St Lucie, Tradition, St. Lucie West, Torino, River Park, Fort Pierce, Jensen Beach, and Hutchinson Island. Typical drive times from PSL City Hall are 12 minutes to St. Lucie West, 18 minutes to Tradition, 25 minutes to Fort Pierce South, and 30-35 minutes to Jensen Beach. We work park-to-park, including Savannas Recreation Area and PSL RV Resort. Afternoon storms pop up fast here, so we plan roofs early and electrical checks between cells.
Repair or replace: what’s smartest for your rig?
If your rooftop unit is 10-12 years old, uses R-22 style components, or has a shorted compressor, replacement is smarter. Parts alone on a compressor job can cross $700, and the result won’t touch the performance of a new high-efficiency unit. If your unit is under 7 years and the issue is a board, capacitor, or fan motor, we repair. We’re not fans of throwing money at dying systems. We’ll price both paths on site, and tell you straight which way we’d go if it were our coach.
What Florida heat and storms do to RV AC systems
Port St Lucie heat and humidity are brutal on rooftop units. Salt air off Hutchinson Island accelerates coil corrosion. Afternoon lightning knocks out control boards and thermostats. According to the National Weather Service in Melbourne, our summer dew points sit in the sticky 70s, which means your AC has to remove a lot of moisture before you feel cool. That’s why clean filters, sealed plenums, and proper voltage aren’t “nice to have.” They’re required for comfort here.

DIY checks you can do before we roll
You can safely try a few basics: 1) Clean or replace the return filter. Even a thin layer of dust hurts airflow. 2) Reset power. Turn the AC off, wait 5 minutes, restore shore power, then restart cool. 3) Check pedestal voltage with a plug-in meter. Under 108 volts, don’t run the AC. 4) Look for ice on the evaporator. If iced, fan only for 45 minutes, then cool again.
If those don’t help, stop. Don’t poke boards or discharge capacitors. We’ve seen too many zaps and busted parts. Not worth it.
Soft starts, surge protection, and solar: what actually helps
Soft start kits make compressors start smoother on 30 amp pedestals and generators. Worth it if you boondock or run two ACs on marginal power. Whole-coach surge protection is a must here due to lightning frequency. According to Progressive Industries specs, their EMS units protect against high/low voltage and open neutrals, not just spikes. Solar helps your batteries and fridge but won’t run an AC by itself unless you’re set up with a serious inverter bank. That’s RV solar repair 201, and we can help design it.

We’re licensed and insured in Florida for mobile RV service. Every repair we perform includes a 12-month workmanship warranty. Manufacturer part warranties follow the brand’s rules, usually 12-24 months. You’ll get a written invoice with model and serial numbers, work performed, and test results. No mystery charges.

One visit, multiple problems solved, so your weekend isn’t shot.

How to prevent the next RV AC breakdown
Here’s the best approach we’ve seen work in Port St Lucie:
- Clean filters every 30 days in summer. No exceptions. Rinse condenser coils from inside out every 6 months. Seal the plenum so cold air can’t bypass the ducts. We use foil tape, not duct tape. Add a surge protector before storm season. Log voltage. Under 108 volts, don’t run AC. Ever.
Do this, and you’ll add years to your unit. We can set you up on a twice-a-year RV service near me maintenance plan if you want zero hassle.
What new RV AC units cost installed in Port St Lucie
Installed pricing for a standard 13.5k BTU rooftop unit runs $1,200-1,700. High-efficiency or 15k BTU units run $1,600-2,400. That includes removal, install, new gasket, start kit as needed, and shroud transfer or replacement. We typically recommend Dometic Brisk II or Coleman-Mach 3 Plus for reliability and parts availability. Honestly, I’d skip lesser-known brands in our climate. Parts delays in July heat are not fun.
According to Coleman-Mach product guidance, 15k BTU units are best for larger coaches or poor insulation.

What manufacturers and codes say about safe operation
Manufacturer specs matter. Dometic and Coleman-Mach both require proper supply voltage, typically 103.5 to 126.5 volts, for warranty coverage. Running below spec overheats motors and boards. The Florida Building Code does not govern RV rooftop AC units directly, but Florida’s frequent surges and lightning make surge protection a smart standard. We follow manufacturer service manuals and torque specs, and we record test readings on every job for your file.

Q: What’s the fastest fix for an RV AC that hums but won’t start?
A: That symptom usually points to a failed start/run capacitor. We test it under load and replace it if out of spec. Most capacitor swaps take 45-60 minutes, and totals usually land between $189-325, depending on brand and access.
Q: Do you work on Dometic, Coleman-Mach, and Furrion units?

Q: Should I repair or replace my old rooftop AC?
A: If your unit is 10-12 years old or has a shorted compressor, replace it. You’ll spend less over the next two summers and get better cooling. If it’s under 7 years a1rvrepair.com rv repair near me and needs a board, capacitor, or fan motor, repair it. We’ll price both and give you our straight recommendation.
Q: Will a soft start let me run my AC on a small generator?
A: A soft start reduces inrush current so compressors start easier on limited power. It helps on 30-amp service and portable generators. It won’t fix low voltage at a bad pedestal, though. Keep voltage above 108 volts or you risk damage. We install soft starts and test results on site.
Q: Do you offer warranties on repairs and new units?
A: Yes. We include a 12-month workmanship warranty on repairs. Manufacturer part warranties typically run 12-24 months, depending on brand and component. You’ll receive a written invoice with all documentation for your records and future service.
Q: Can my solar setup run the AC?
A: Not by itself, unless you’ve got a large lithium battery bank and a serious inverter. Solar is great for batteries, lights, and fridges. One rooftop AC can draw 12-16 amps at 120 volts, which is a big continuous load. We can design upgrades if you’re heading toward off-grid comfort.
Q: What maintenance should I do to prevent AC issues in PSL?
A: Clean or replace return filters monthly in summer. Rinse condenser coils twice a year. Seal the plenum so cold air goes into the ducts, not the roof cavity. Add whole-coach surge protection before storm season. Never run the AC below 108 volts. These steps prevent most failures we see.
