Why AC Matters Here

Your RV's Climate System Works Harder in Fellsmere

Fellsmere sits in the heart of Indian River County, where summer temperatures regularly hit 95 degrees and the humidity doesn't let up from May through October. That means your RV's rooftop AC isn't just running for comfort. It's protecting your electronics, your food, your pets, and honestly, your sanity. According to the Dometic Brisk II service manual, these units are rated for a maximum ambient temperature of 115 degrees Fahrenheit. Your RV's roof surface gets close to that on a July afternoon here, which pushes these systems right up against their design limits.

We've been repairing RV air conditioning and heating systems in Fellsmere for over 15 years. In that time, we've completed more than 3,200 repairs across Indian River County, and a solid 40% of those involved AC or heating issues. Here's what we've learned: most AC failures down here aren't sudden. They're the end result of months of stress on a system that's been working too hard for too long without maintenance. Have you checked your return air filter in the last 30 days? If not, that's the first thing we'd look at.

We service everything related to your RV's climate system: rooftop AC units from Dometic, Coleman-Mach, Advent, and Furrion. Thermostats, both analog and digital. Refrigerant systems, including leak detection and recharging to factory specs. Ductwork that's collapsed, disconnected, or leaking cold air under the floor where it does nothing useful. Dual AC setups on larger Class A and fifth-wheel rigs. Compressor diagnosis and replacement. Soft-start kits that let you run your AC on 30-amp power without tripping breakers. And ceiling assembly work, including the interior shroud, filters, and distribution box. If it moves air in your RV, we fix it.

Florida-Specific Challenges

What Fellsmere's Climate Does to RV AC Systems

Indian River County averages 87 days per year above 90 degrees, according to NOAA climate data. That's nearly three straight months of extreme heat, and your rooftop AC is running 14-16 hours a day during those stretches. Compare that to an RV parked in the Blue Ridge Mountains, where the unit might cycle 4-5 hours. You're putting triple the wear on every component: the compressor, capacitors, fan motors, and control boards.

Then there's the humidity. Fellsmere regularly sees 85% or higher relative humidity, which means your evaporator coil is pulling gallons of moisture out of the air every day. When that condensation drain clogs, and it will, water backs up into the ceiling assembly and can cause damage that crosses into roof repair territory. We clear those drains and treat them with mold inhibitor during every AC service call.

For RVers parked closer to Sebastian or Indian River Shores, salt air corrosion is another concern. That salty moisture attacks condenser coil fins, electrical connections, and mounting hardware. Coleman-Mach's installation guide specifically recommends bi-annual coil cleaning in coastal environments. We've seen units in Wabasso corrode twice as fast as those parked just 15 miles inland here in Fellsmere.

How It Works

Three Steps to a Cool RV

1

Call Us

Dial 772-356-1760 and tell us what's going on. AC blowing warm? Compressor humming but not starting? The more detail you give us, the better prepared we'll arrive. Most appointments are within 24 hours, and same-day slots are often available.

2

Diagnose

We test refrigerant pressure, compressor amp draw, fan motor speeds, thermostat signals, supply voltage, and airflow through every duct run. You'll get a clear explanation of the problem and a firm price before we touch anything. No guessing, no surprises.

3

Repair

We fix it on site, then run the system under full load for 20-30 minutes. We measure supply and return air temperatures, confirm proper cycling, and verify the thermostat accuracy. You only pay after everything checks out and you're satisfied.

Common Questions

RV AC & Heating Repair FAQ

Start with the return air filter. A clogged filter restricts airflow and can freeze the evaporator coil within hours. If the filter looks clean, the most common causes are low refrigerant from a slow leak, a weak compressor, or dirty condenser coils. In Fellsmere's heat, condenser fins get packed with pollen and debris fast. We'll run a full diagnostic to pinpoint the exact issue before quoting any repairs.
It depends on the specific problem. A thermostat replacement runs $95-$300. Refrigerant recharge is $150-$400 including leak testing. Rooftop AC repair ranges from $200-$800, and compressor work costs $350-$1,200. We always provide a firm quote after diagnosis so there aren't any surprises. A full AC diagnostic starts at $125.
Most repairs wrap up in 1-3 hours on site. A thermostat swap or refrigerant recharge usually takes about an hour. Compressor replacement or a full rooftop unit swap runs closer to 3-4 hours. We handle everything at your location, so you don't need to drive anywhere or drop your rig off at a shop for days.
Yes, we service all major brands. Dometic and Coleman-Mach account for roughly 85% of the rooftop units we see, which lines up with RVIA industry production data. We also work on Advent, Furrion, and Airxcel models. We carry common replacement parts for each brand on the truck, so most repairs don't require a second trip or a week-long wait for parts to arrive.
A properly sealed system shouldn't need recharging at all. Refrigerant doesn't get "used up" like fuel. If your system is low, there's a leak somewhere that needs fixing first. Topping off a leaking system just means you'll call us again in a few months. We always pressure-test for leaks before adding refrigerant, then recharge to the factory specs listed in your Dometic or Coleman service manual.
A soft-start kit like the Micro-Air EasyStart reduces your compressor's startup power draw by about 65%. That's a big deal if you're on 30-amp shore power and keep tripping breakers, or if you want to run AC off a portable generator. It also reduces the mechanical shock on the compressor at startup, which can extend its lifespan. Installation takes under an hour and costs $250-$500 depending on the unit.
We do. When it's 95 degrees outside and your AC stops working, that's not a next-week kind of problem. We offer same-day service Monday through Saturday, 7 AM to 7 PM. Call 772-356-1760 and let us know it's urgent. We'll fit you in as quickly as possible, usually within a few hours depending on our current schedule and your location in the area.
Watch for these warning signs: the unit runs but blows warm air, you hear a loud clicking or buzzing at startup, the compressor trips the breaker repeatedly, or the system cycles on and off every few minutes. A compressor pulling higher-than-normal amps is also headed for failure. If you catch it early, a hard-start capacitor kit ($75-$150) might buy you more time. Waiting too long can damage other components and turn a $400 repair into a $1,200 one.
