RV air conditioners and furnaces take a beating in Florida. Rooftop AC units run 8-10 months a year down here, and the humidity, salt air, and constant cycling wear out capacitors, fan motors, and coils faster than most owners expect. We see these problems every week across Port St. Lucie, FL and the Treasure Coast. Here's what we fix and what it typically costs.
Dometic, Coleman, and Advent rooftop units all fail the same ways. Capacitor burns out, condenser coils get caked with dirt, fan motor bearings seize, or the compressor starts struggling. We diagnose the actual cause on-site and fix it. This is the #1 call we get from May through October.
$120-350 - 45-90 minStart capacitors, run capacitors, and hard start kits. This is the #1 RV AC repair we do during Florida summers. A bad capacitor means the compressor can't kick on, or it trips the breaker every time it tries. We test and replace on-site in about 30 minutes. Cheap part, big difference.
$80-250 - 30-60 minCondenser fan, evaporator fan, or both. The bearings seize from Florida humidity and salt air, especially on rigs parked near the coast. You'll hear grinding or rattling before the motor finally stops. We pull the shroud, swap the motor, and test airflow. Usually takes about an hour on the roof.
$150-300 - 60-90 minAnalog dials, digital panels, and Dometic CCC2 controllers all fail eventually. Sometimes it's the thermostat itself, sometimes it's wiring behind the wall. We test the signal, check the connections, and swap the unit if it's dead. Quick job that makes a big difference in comfort.
$60-150 - 20-40 minSuburban and Atwood LP furnaces are what you'll find in almost every RV. Igniter boards fail, sail switches stick, blower motors quit, and gas valves go bad. The furnace clicks but never lights, or lights then shuts down after a few seconds. We carry igniter boards and sail switches for same-visit repairs.
$100-280 - 45-90 minIce forming on your RV air conditioner usually means low airflow from dirty filters, a failed evaporator fan motor, or a thermostat that's cycling wrong. Less common but possible: low refrigerant in the sealed system. We clear the ice, find the root cause, and fix it so it doesn't come back next week.
$80-200 - 30-60 minCollapsed ducts, disconnected flex lines, busted registers, and unbalanced airflow are all common in older rigs. If the front of the coach is freezing and the back bedroom barely gets any air, the duct system is the problem. We reconnect, patch, or replace duct runs and balance the output.
$80-180 - 30-60 minWhen the compressor is shot or repairs cost more than the unit is worth, it's time for a new one. We remove the old rooftop unit, install a new Dometic or Coleman, wire it up, test it, and seal the roof penetration. We order the unit, schedule the install, and handle everything on-site.
$800-1,800+ - 3-5 hoursIf the fan runs fine but the air coming out isn't cold, you're looking at a capacitor issue, dirty coils, or a compressor that's on its way out. Don't run it like this for long, the compressor overheats and then you're replacing the whole unit.
A breaker that trips when the AC starts usually means a bad start capacitor, a locked rotor on the compressor, or wiring that can't handle the amp draw. We test the draw on-site and tell you exactly what's causing it.
The clicking means the ignition sequence is starting but something's stopping it. Usually a stuck sail switch, a bad igniter board, or a gas valve issue. Suburban and Atwood furnaces are straightforward to diagnose once we pull the cover.
Ice on the coils restricts airflow and makes the unit work harder. Common causes: dirty filter, failed fan motor, or thermostat cycling the compressor too often. Shut it off for a few hours and call us before you run it again.
Fan motor bearings go bad, compressor mounts loosen, and shroud hardware vibrates loose. Any new noise from the roof unit means something is wearing out. Catching it early is usually a $150 fan motor swap instead of an $800+ unit replacement.
Call 772-276-6465 or submit an estimate request online. Tell us what's happening, AC not cooling, furnace won't light, weird noise from the roof. We'll give you a time window, usually same or next day across Port St. Lucie and the Treasure Coast.
Our tech shows up with a ladder, diagnostic tools, and a stocked truck. We climb up, pull the shroud, test the capacitor, check the fan motor, inspect the coils, or pull the furnace cover. You get a written estimate before we touch anything. No guesswork billing.
Most RV AC and heating repairs finish in 1-2 hours. We carry capacitors, hard start kits, fan motors, thermostats, igniter boards, and sail switches. If it's a full unit replacement, we order the Dometic or Coleman, schedule the install, and get it done in one visit.
AC dying in July at a Florida campground is a real emergency. We answer calls around the clock across St. Lucie, Martin, and Indian River counties. If it's 95 degrees and your AC just quit, we'll get someone out there.
Our technicians are RVIA certified through the Recreation Vehicle Industry Association and hold current Florida state licenses. AC and furnace work involves electrical, LP gas, and rooftop access. Credentials matter when someone's on your roof with a multimeter.
All labor is warrantied for 90 days. If a repair we did fails within that window, we come back and fix it at no charge. Parts carry the manufacturer's warranty on top of that. You're not calling back in a month to argue about a capacitor that didn't hold.
AC died in July - absolute worst timing. They came out same day, replaced the capacitor and cleaned the coils. Cold air in under two hours. These guys saved our summer.
Furnace kept clicking but wouldn't light. Tech found a bad sail switch and replaced it right there. $120 fix that a shop wanted $350 for. Honest and quick.
Needed a whole new rooftop AC unit. They ordered a Coleman, came back two days later, removed the old one and had the new one running by afternoon. Clean install, properly sealed.
Most RV AC repairs run $80-350 depending on the problem. Capacitor and hard start kit replacements come in at $80-250. Fan motor swaps run $150-300. Thermostat replacements are $60-150. A full rooftop unit replacement runs $800-1,800+ depending on the unit you choose. We always write up an estimate before starting, no surprises.
An RV AC that runs but doesn't cool usually points to a failed capacitor, dirty condenser coils, a worn-out compressor, or low refrigerant in a sealed system. In Florida's heat we see capacitor failures more than anything else. The constant run time burns them out. We can test the capacitor on-site in about 5 minutes and have a replacement on the truck.
Yes. We repair and replace RV rooftop AC units on-site at your campsite, driveway, RV park, or storage lot. We carry a ladder, the right tools, and common parts for Dometic, Coleman, and Advent units. You don't need to tow anywhere. The only exception is if we can't safely access the roof at your specific location.
An RV AC that trips the breaker usually has a failing compressor, a bad start capacitor, or a locked rotor. It can also be a wiring issue or an undersized power source. If you're on a 30-amp service running two AC units, that alone will trip it. We test amp draw on the compressor to figure out whether it's the unit or the power supply.
At minimum, once a year before the hot season starts. In Florida, where AC units run 8-10 months out of the year, twice a year is better. A service visit includes cleaning the coils, checking the capacitor, testing the fan motor, inspecting the roof seal, and cleaning or replacing the filters. Usually runs about $80-120 for a maintenance visit.
RV furnaces fail for a few common reasons: a bad igniter board, a stuck sail switch, a failed blower motor, or a gas valve issue. Suburban and Atwood LP furnaces use a sail switch to verify airflow before the gas valve opens. If that switch sticks or fails, the furnace clicks but never lights. We carry igniter boards and sail switches for same-visit repair.
A rooftop RV AC unit typically lasts 8-15 years depending on usage and maintenance. In Florida, where units run hard most of the year, 8-10 years is more realistic. Regular coil cleaning and filter changes extend the life. Once a compressor starts struggling or the unit needs both a new fan motor and capacitor, it's often smarter to replace the whole unit.
Yes. We remove old rooftop units and install new Dometic or Coleman replacements on-site. The job takes 3-5 hours including wiring, testing, and resealing the roof penetration. We order the unit, schedule the install, and handle everything. Total cost runs $800-1,800+ depending on the unit and whether it's a straight swap or needs adapter brackets.
