What We Fix

RV AC repair in Stuart, done where you're parked.

Martin County's mix of high humidity and salt air is brutal on RV cooling and heating systems. Rooftop AC units run nearly year-round here, and that constant cycling eats through capacitors, corrodes condenser fins, and wears out fan motor bearings faster than the owner's manual suggests. We see these failures every single week in Stuart, Palm City, and Jensen Beach. Here's what we fix and the typical cost range.

Rooftop A/C Not Cooling

The most common call we get from Stuart RV owners, especially May through November. Martin County humidity forces these units to work overtime. Dirty condenser coils, dead capacitors, seized fan motors, or a compressor pulling too many amps. We climb up, pull the shroud, and figure out exactly what's going on before quoting the repair.

$125-375 - 45-90 min

Compressor and Capacitor Replacement

Start caps, run caps, and hard start kits are what we replace more than anything else during the warm months. A blown capacitor means the compressor hums but won't start, or it trips the breaker on every attempt. We test cap values and amp draw right at your rig. The part is cheap, the swap takes 30 minutes, and the difference is immediate.

$85-260 - 30-60 min

Fan Motor Swap

Condenser fan or evaporator fan, the salt air along the St. Lucie River and Hutchinson Island corrodes bearings and windings faster than inland rigs experience. You'll hear grinding or squealing before the motor finally seizes. We pull the shroud, swap the motor, and verify airflow. Most of these take about an hour on the roof.

$160-320 - 60-90 min

Thermostat Diagnosis and Replacement

Analog dials, digital panels, and Dometic CCC2 controllers. Sometimes the thermostat reads the wrong temp, sometimes it won't send a signal at all. Could be the unit itself or corroded wiring behind the panel. We test the control signal, check every connection, and replace it if it's gone. Fast job, big comfort impact.

$65-160 - 20-45 min

Furnace Ignition and Heating Repair

Suburban and Atwood LP furnaces are in almost every RV we service. The igniter board fails, the sail switch gets stuck, the blower motor dies, or the gas valve won't open. You'll hear the furnace click through its startup cycle and then go silent. We carry replacement igniter boards and sail switches so most furnace repairs finish in one trip.

$110-290 - 45-90 min

Freeze-Up and Ice on Coils

Ice building up on your AC evaporator coils chokes airflow and makes the whole unit work harder until it shuts down. In Martin County's muggy climate, this happens faster than you'd think. Common culprits are a clogged filter, a bad evaporator fan motor, or a thermostat that won't cycle the compressor properly. We clear the ice, find the root cause, and fix it for good.

$85-220 - 30-75 min

Duct Work and Airflow Balancing

Collapsed flex ducts, disconnected runs, broken ceiling registers, and uneven airflow are standard problems in older rigs. The front of the coach is cold and the back bedroom barely gets a breeze. We trace every duct line, reconnect or replace what's failed, and rebalance the whole system so every vent actually pushes air.

$90-200 - 30-75 min

Full Rooftop A/C Replacement

When the compressor is done or repair costs exceed the value of the unit, we remove the old one and install a new Dometic or Coleman right at your location. That includes wiring, testing, and sealing the roof opening with Dicor sealant. We order the unit, schedule the install date, and handle the entire swap on-site.

$850-1,900+ - 3-5 hours

Warning Signs

5 signs your RV cooling or heating system needs help.

01

The AC runs constantly but the coach never gets cold

If the unit is running full blast and the interior barely drops below 80 degrees in Stuart's summer heat, a weak capacitor, dirty coils, or a failing compressor is usually the problem. Running it in this state burns out the compressor faster and drives up your electric bill at the RV park.

02

Breaker pops every time the AC compressor kicks in

A tripping breaker at startup points to a bad start capacitor, excessive amp draw from a worn compressor, or corroded wiring at the disconnect. If you're on 30-amp shore power at a Martin County campground, you might also be overloading the circuit with two AC units and a water heater.

03

Furnace clicks through its cycle but won't ignite

You hear the blower start, the igniter click, and then the whole sequence shuts down after 15-30 seconds. That's a textbook sail switch failure, a dead igniter board, or a blocked exhaust tube. Suburban and Atwood furnaces both do this, and we've got the parts to fix it same day.

04

Water dripping from the ceiling around the AC unit

This can be condensation from a frozen evaporator coil, a cracked drain pan, or a failed gasket between the rooftop unit and the ceiling assembly. In Martin County's humidity, even a small gasket failure lets moisture pour in. Ignoring it leads to ceiling delamination and mold.

05

New grinding, rattling, or buzzing noise from the roof

Fan motor bearings going bad, a loose shroud, or vibration from a failing compressor mount. Any new sound from the rooftop unit means a part is wearing out. Getting it checked now is usually a $160-320 motor swap instead of an $850+ unit replacement next month.

1

Call or Request an Estimate

Call 772-280-3915 or fill out the online estimate form. Tell us what's happening, whether the AC stopped cooling, the furnace won't light, or there's a weird noise coming from the rooftop unit. We'll set a time window, usually same or next day anywhere in Martin County.

2

On-Site Diagnosis

Our technician arrives with a ladder, diagnostic tools, and a truck stocked with common parts. We climb the roof, test capacitor values, measure amp draw, inspect the coils, or pull the furnace access panel. You get a written estimate before we start any repair work. No guesswork, no surprise charges.

3

Atwood furnace wouldn't light, just kept clicking. The tech found a corroded sail switch and had a new one on the truck. Fixed in about 40 minutes for $135. A shop in Jensen Beach wanted $400 just to look at it. Very happy with the honest pricing.

Tom B.Travel Trailer Owner, Stuart
Had them replace our entire Coleman rooftop unit at the Nettles Island RV park. They ordered the unit, showed up three days later, pulled the old one, and had the new one sealed and running by mid-afternoon. Professional job from start to finish.

FAQ

RV AC repair questions from Stuart owners.

How much does RV AC repair cost in Stuart, FL?

Most RV AC repairs in the Stuart area run between $85-375. Capacitor swaps and hard start kits fall in the $85-260 range. Fan motor replacements cost $160-320. Thermostat jobs are $65-160. A full rooftop unit replacement runs $850-1,900+ based on brand and tonnage. We write up an estimate before starting any work.

Why is my RV air conditioner blowing warm air?

Martin County humidity puts extra load on RV AC systems. The usual culprits are a failed run capacitor, clogged condenser coils, a worn compressor, or restricted airflow from a dirty filter. Capacitors burn out fast here because the unit rarely cycles off during the summer months. We can test yours on-site in about five minutes.

Do you service RV rooftop AC units on-site in Stuart?

Yes. We repair and replace RV rooftop AC units wherever your rig is parked. That includes RV parks off US-1, driveways in Palm City, storage lots in Jensen Beach, and campsites around the St. Lucie River. We bring a ladder, diagnostic tools, and stock parts for Dometic, Coleman, and Advent units.

Why does my RV AC trip the breaker when it starts?

A failing start capacitor, a compressor with a locked rotor, or corroded wiring connections are the most common causes. Running two AC units on a 30-amp pedestal at a Martin County campground can also overload the circuit. We measure amp draw at the compressor to figure out whether it's the unit or the power source.

How often should I service my RV AC in Florida?

Twice a year is the right schedule for Stuart and the Treasure Coast. AC units here run nearly year-round because of the humidity. A maintenance visit covers coil cleaning, capacitor testing, fan motor inspection, filter swap, and a check of the roof gasket seal. Runs about $85-130 per unit.

Why won't my RV furnace ignite?

Suburban and Atwood LP furnaces rely on a sail switch to confirm airflow before the gas valve opens. If the sail switch sticks or the igniter board fails, the furnace clicks through its startup sequence and shuts down. A clogged exhaust tube or low battery voltage causes the same symptoms. We carry replacement boards and switches on the truck.

How long do RV AC units last in Martin County?

Expect 7-10 years from a rooftop RV AC unit with regular maintenance in this climate. Units up north can push 12-15 years because they don't run as hard. Salt air near the coast also corrodes fins and electrical connections faster. Once the compressor is struggling and you need both a new fan motor and capacitor, full replacement usually makes more sense financially.

Can you replace a full rooftop AC unit at my campsite?

Absolutely. We remove the old rooftop unit and install a new Dometic or Coleman right where you're parked. The job runs 3-5 hours including wiring, testing, and sealing the roof penetration with Dicor self-leveling sealant. Total cost is $850-1,900+ depending on the unit and whether adapter brackets are required.
