Why Port St Lucie RV owners call us first for mobile repairs

You want a tech who shows up on time, has the right parts, and fixes it right the first time. That’s us. We live and work in Port St Lucie, so we know how salt air on Hutchinson Island eats roof seals, how summer humidity wrecks AC capacitors, and how a week of afternoon storms can expose a tiny roof crack. We’ve repaired 3,500+ rigs across St. Lucie County and the Treasure Coast, from Tradition to Jensen Beach.

We stock common parts on the van, so you’re not waiting three days for a fan motor. We carry Dometic and Coleman-Mach capacitors and blower wheels, Suburban and Atwood igniters, Norcold and Dometic fridge boards, Lippert slide-out parts, Thetford valves, Shurflo pumps, Dicor and Eternabond for roofs. Ever had a tech show up with only a screwdriver and a smile? Not helpful.

Pricing is straight. Service call in Port St Lucie is $99, diagnosis is $89, then parts and labor. No guesswork. And we’re licensed, insured, and back most repairs with a 12-month parts and labor warranty. Reviews sit at 4.9 stars from 1,247 customers. That didn’t happen by accident.

We service Tradition, St Lucie West, Sandpiper Bay, and River Park. Fast access via Crosstown Parkway and US-1.

Mobile RV AC repair and why Florida heat hits rigs harder

RV AC repair is our number one call from May through September. In PSL, heat and humidity stress start capacitors and fan motors. You’ll hear the compressor hum but no cold air, or the breaker trips after 30 seconds. We test capacitors with a meter, check amp draw, and inspect the run capacitor on Coleman-Mach and Dometic units. Many repairs are under $250, like a failed cap or contactor. A seized fan motor or a fried control board runs $350 to $650. Full rooftop AC replacement usually lands between $1,200 and $2,100 installed.

Quick pro tip. Rinse rooftop coils every 60 days in summer. Takes 30 minutes and extends life. According to Dometic service bulletins, restricted airflow is a leading cause of premature failure on rooftop units. We’ve seen it. Last week near the MIDFLORIDA Event Center, we swapped a swollen 45+5 capacitor on a Mach 15. Forty-five minutes, cold again. Sound familiar?

RV refrigerator repair that actually keeps food cold

Absorption fridges are fussy. If your Norcold or Dometic is warm but the freezer is barely frosty, we’ll check the heating element, control board, gas pressure, and ventilation baffles. A blocked flue or dead thermistor is common. Board replacements run $280 to $480. Elements are usually $220 to $350 installed. Bad cooling units are a different animal, often $1,300 to $1,900. Honestly, if your cooling unit is rust-stained with that ammonia smell, don’t waste time on band-aids.

We use a Fluke digital thermometer and probe fins before we touch a wrench. And we follow manufacturer specs for clearances behind the unit. According to the Norcold installation manual, inadequate rear ventilation kills performance. We’ve rebuilt more than a few chimneys on rigs parked along Prima Vista Boulevard because a previous installer skipped baffles. Big mistake.

Emergency RV repair and same-day service on the Treasure Coast

If you’re stranded at Savannas Preserve or a full-timer at PSL RV Resort and you lose 120-volt power or your slides won’t move, call us. We hold same-day windows for breakdowns. In-city service call is $99. After-hours emergency add-on is $149. We usually reach Tradition or St Lucie West in 25 to 35 minutes. Stuart and Jensen Beach are 25 to 40. Fort Pierce is 20 to 30 depending on US-1 traffic.

We’ve cleared locked-up Lippert jacks in a grocery parking lot, rewired a burnt shore power inlet on the island, and replaced a water heater gas valve before a family’s weekend at Jetty Park. No shop drop-off. No towing.

Emergency call at Jensen Beach. Shore power inlet was scorched. New inlet and pigtail installed same visit.

Roof and water leak repair that survives Florida storms

Water wins if you let it. We see failed lap sealant, cracked skylights, and punctures from low branches on Crosstown Parkway. We clean with mineral spirits, prime if needed, then use Dicor self-leveling or Eternabond with UV-rated edge seal. Reseal jobs are usually $8 to $12 per linear foot. A full roof replacement is a serious project at $140 to $190 per linear foot depending on TPO, EPDM, or fiberglass.

We also fix soft spots before they spread. Last month in Sandpiper Bay, we opened a 2-foot section, replaced the luan, and sealed with new membrane. Took 5 hours. Dried out, no mold. Don’t wait till the next tropical system shows up. Afternoon downpours find every pinhole.

RV electrical repair and battery systems done the right way

We chase shorts and ghost loads all the time. Flickering 12-volt lights usually point to poor grounds or a dying converter. We test under load, then check the WFCO or Progressive Dynamics converter output. Replacements run $320 to $560 installed. For house batteries, we prefer AGM or lithium when the budget allows. A basic battery service with new cables and a smart fuse block is $150 to $350 plus parts.

We follow the National Electrical Code Article 551 for RVs as a design reference, and manufacturer wiring diagrams. Bad habit we see often. People stack too many ring terminals on a single lug. Loose connections heat up and melt stuff. According to Cummins Onan RV generator maintenance guidelines, oil changes are due every 150 hours and air filters at 300. Skip that and you’ll be calling us from a rest area.

RV generator repair and service that prevents weekend failures

Onan 4k and 5.5k units are common around PSL. If yours starts then dies, we’ll check low oil, fuel pickup height, and governor adjustments. Carb replacements usually fall between $260 and $480. A standard service package with oil, filter, air filter, and spark plug is $189 to $329 depending on model. We carry Onan green parts, not mystery knockoffs. Opinion here. Cheap carbs are a headache. We’ve had new ones arrive with casting grit inside. Not worth the $40 saved.

Onan service in Tradition. Oil change, carb swap, and governor set under spec.

Plumbing, water heaters, and winter issues you can avoid

We fix Shurflo pumps, PEX leaks, Thetford valves, and Suburban or Atwood water heaters. If your heater clicks but won’t light, soot around the burner gives it away. We clean the tube, verify 11 inches water column on LP, and test the ECO and thermostat. Most heating repairs are $180 to $450. Full water heater swaps land at $900 to $1,400. Anode rods on Suburban tanks should be replaced when 75% gone. Costs about $49 and 20 minutes. Worth every penny.

Common mistake. People use Teflon tape on flare fittings. That creates leaks. Use the correct flare and torque. We carry a Ridgid flaring kit and Apollo PEX tools for clean work.

Slide out and leveling jack repair without dragging you to a shop

Stuck slide or dead jack before checkout at Larry P.Wallace Park? We see it weekly. We diagnose Lippert, Power Gear, and HWH systems. Microswitches, sheared pins, low voltage, or out-of-sync control boards are the usual suspects. Slide out motor swaps are often $350 to $700. Jack cylinder reseals or replacements run $200 to $500 each. We carry ATF and AW-32 fluids, plus spare pins and switches. And we’ll teach you the manual retract process emergency rv repair so you’re not stranded again.

Slide motor replacement in St Lucie West. Bad microswitch had the control board fooled.

Solar and inverter troubleshooting, the Treasure Coast way

Solar is big with full-timers on Hutchinson Island and boondockers up near Fort Pierce Inlet. If you’re not getting expected watts, we test Voc and Isc at the panels, then trace voltage drop through MC4 connections, the charge controller, and to the battery bank. Many “bad panels” turn out to be one corroded connector. Solar troubleshooting typically runs $180 to $400. Inverter swaps vary widely, but a 2000-watt pure sine replacement with clean cabling sits in the $650 to $1,100 labor range, plus the unit.

We label every cable and leave a diagram in your pass-through. Future you will thank us.

A quick story from last week in Tradition

We got a call at 7:10 am. Family of five. AC dead. Coleman-Mach wouldn’t start. We were onsite by 8:05. Found a ballooned 45+5 capacitor and a crispy spade on the fan lead. Swapped cap, replaced the terminal with a heat-shrink connector, cleaned the coils, checked amp draw at 12.7 A. Inside temp dropped from 89 to 77 in 40 minutes. Total was $289 with tax. Kids were back to sleeping on the bunk slide by lunch. Good day.

What we work on every day

Travel trailers, fifth wheels, motorhomes Class A, B, C Dometic, Coleman-Mach, Suburban, Atwood, Norcold, Lippert, HWH, Power Gear
