WHAT WE SERVICE

RV AC & HVAC Service in Vero Beach, FL

Vero Beach averages 90+ degree days for about five months a year. Humidity regularly sits above 80%. That's a brutal combination for any air conditioning system, and RV AC units are smaller, lighter, and work harder than residential ones. They weren't built for non-stop Florida summers, but that's exactly what we ask them to do. Our team specializes in keeping these systems running efficiently, and when they fail, we get them back up fast.

TL;DR

We repair and replace rooftop AC units, furnaces, thermostats, ductwork, and heat pumps for all RV types. Mobile service across Vero Beach and Indian River County. AC recharge starts at $125, thermostat swaps at $85, full unit replacement from $800. Call 772-218-5861.

Rooftop AC Repair

Most RVs have one or two rooftop AC units. We service Dometic, Coleman-Mach, and Advent models. Common repairs include compressor issues, fan motor replacement, capacitor swaps, and control board fixes. We also clean condenser and evaporator coils, which should be done at least twice a year in Florida's pollen-heavy air.

Furnace Service & Repair

Even in Florida, you'll need your furnace on January and February mornings when temps drop into the 30s and 40s. We service Suburban, Atwood, and Dometic furnaces. Burner cleaning, igniter replacement, sail switch testing, and exhaust tube clearing. Mud dauber wasps love nesting in furnace exhaust tubes here - we see it constantly. Service runs $150-350.

Thermostat Replacement

A faulty thermostat can make your AC short-cycle, run continuously, or not start at all. We install analog, digital, and smart thermostats from Dometic and Coleman-Mach. Upgrading from an old analog unit to a digital thermostat with programmable settings usually costs $85-175 and gives you much better temperature control.

Refrigerant Recharge

Low refrigerant means your AC blows warm air, no matter how long it runs. We check for leaks first, because just adding refrigerant without finding the leak means you'll be right back where you started in a few weeks. Once we've confirmed the system is sealed, we recharge to manufacturer specs. Runs $125-225 including the leak check.

Ductwork & Vent Repair

Crushed ducts, disconnected sections, and leaking joints waste cold air before it ever reaches your living space. We've seen RVs where 30% of the cooled air was going under the floor instead of into the cabin. We seal joints with mastic, replace collapsed sections, and make sure every vent is delivering proper airflow. This alone can make your AC feel twice as effective.

Heat Pump Service

Heat pumps provide both cooling and heating from one rooftop unit. They're efficient in mild climates like Vero Beach, where winter lows rarely go below 40. We service the reversing valve, defrost control board, and both operating modes. If your heat pump cools fine but won't heat, the reversing valve solenoid is usually the culprit.

FLORIDA-SPECIFIC CHALLENGES

Why Florida Is So Tough on RV AC Systems

Constant Heat Load

From May through October, your RV AC is running 12-16 hours a day. That's three times the runtime of an RV parked in the mountains of North Carolina. Compressors wear out faster. Fan bearings fail sooner. Capacitors weaken from the constant cycling. We recommend a preventive AC check in April before the real heat hits, and another in October after your system has worked all summer.

Salt Air Corrosion

If you're parked near the coast - and a lot of Indian River County is within a few miles of salt water - your condenser fins are corroding faster than you'd think. Salt spray accelerates aluminum corrosion, which blocks airflow through the condenser and reduces cooling capacity. We clean and treat condenser coils with corrosion inhibitor. Consider it a basic maintenance step if you spend time near the barrier island or Indian River Shores.

Humidity and Mold Growth

Florida's humidity creates the perfect environment for mold and mildew inside your AC's evaporator housing. That musty smell when you first turn on the AC? That's mold. Left unchecked, it affects air quality and can cause health issues. We clean the evaporator coil, treat the drain pan, and check the condensation drain line. A clogged drain line can also leak water into your ceiling or walls, leading to expensive damage that overlaps with roof repair territory.

Power Demands at RV Parks

Many older RV parks in Vero Beach and Sebastian only offer 30-amp service. Running a single 15,000 BTU rooftop AC on 30 amps is fine. Trying to run two is a recipe for tripped breakers. We install soft-start kits that reduce your AC's startup draw by 65-70%, which can let you run two units on a 30-amp connection that wouldn't support them otherwise. It's one of our most popular upgrades, running $200-350 installed.

OUR PROCESS

How We Fix RV AC & HVAC Problems

1

Tell Us the Symptoms

Call 772-218-5861 and tell us what's happening. AC blowing warm? Making a strange noise? Not turning on at all? The more detail you can give us, the more prepared we'll be when we arrive. We can usually schedule within 24 hours.

2

Full HVAC Diagnostic

We test everything: refrigerant pressure, compressor amp draw, fan motor operation, thermostat signal, electrical supply, and airflow through the ductwork. We show you what we found and give you a firm quote before starting repairs.

3

Repair and Test Under Load

We complete the repair on-site, then run the system for at least 20 minutes to verify it's cooling to spec. We check supply and return air temperatures, verify proper cycling, and make sure your thermostat is reading accurately. You pay only after we've confirmed it's working right.

FAQ

RV AC & HVAC Questions

How much does RV AC repair cost in Vero Beach?

An AC refrigerant recharge runs $125-225. Thermostat replacement costs $85-175. A full rooftop AC unit replacement ranges from $800-2,200 depending on the brand and BTU rating. Furnace service runs $150-350. We give you the exact price before any work begins.

Why is my RV AC running but not cooling?

The most common reasons are low refrigerant, a dirty condenser coil, a frozen evaporator, or a failing compressor. In Florida's heat, your AC works overtime and coils get clogged with dust and pollen fast. We check refrigerant levels, clean both coils, inspect the compressor, and test the fan motors. Usually takes about an hour to diagnose.

Can you replace a rooftop RV AC unit on-site?

Yes. We carry Dometic and Coleman-Mach replacement units and can swap a rooftop AC at your location. The job usually takes 3-4 hours including removal of the old unit, mounting the new one, sealing the roof penetration, and testing the system. We handle the electrical connections and thermostat programming too.

How often should I service my RV AC in Florida?

At least twice a year if you're using your RV regularly in Florida. The combination of heat, humidity, and salt air near the coast wears on AC components faster than in drier climates. We recommend a spring tune-up before the hot months and a fall check after heavy summer use.

My RV furnace won't ignite. What's wrong?

Start with the ignition board and sail switch, because those are the two components that fail most often. The sail switch proves airflow to the board, and if it's sticking, the furnace won't even attempt to light. After that, we check LP gas pressure at the regulator. Mud dauber wasps can also block the exhaust tube, which is super common in Florida since the furnace sits idle most of the year. We'll test the full ignition cycle and pinpoint the problem.

What's a soft-start kit and should I get one?

If your breaker trips every time the AC kicks on, a soft-start is the fix. Products like the Micro-Air EasyStart cut your compressor's startup draw by around two-thirds. That's a game changer if you're on 30-amp shore power or running off a portable generator. We install them right on the rooftop unit, and the whole job usually takes under an hour. Runs $200-350 depending on the unit.

Do you service RV heat pumps?

We do. One thing to know about heat pumps is they struggle once outdoor temps drop below about 40 degrees, so they won't replace a propane furnace for those cold January mornings. But for most of the Vero Beach winter, they're perfect. We handle reversing valve issues, defrost board swaps, and refrigerant work on Dometic and Coleman-Mach models.

Why does my RV AC freeze up?

You'll usually spot ice forming on the unit or water dripping inside where it shouldn't be. The most likely cause is a clogged return filter choking off airflow to the evaporator coil. Low refrigerant is the next possibility, and a worn blower motor is third on the list. Shut the system off and let everything thaw before you check the filter. Clean filter but still freezing? That points to a refrigerant leak, and you'll want us to take a look.
