You Get An RV Air Conditioner That Works, Not Empty Promises, in Guntersville, Alabama
Just at the wrong time, your AC quit, just blows warm air, or doesn't blow at all. You need it fixed, not guessed at. Our RVTI-certified technicians diagnose the actual problem, saving time and money.
You get good cold air, we sweat it out.
You've probably already tried the basics. Checked the thermostat. Flipped the breaker. Maybe even climbed on the roof to look at the unit. The AC still isn't cooling, or it's blowing air that's barely cooler than what's outside.
An Alabama summer inside a camper with no AC isn't just uncomfortable, it's miserable. And the last thing you want is a shop that swaps parts for days, or to buy a new unit if the one you have can be fixed, what's worse is when all that still doesn't fix the problem.
You deserve better, someone who knows how to diagnose the real issue, fix it once, and get you back to cool air. That's what we do.
Common RV AC Problems We Fix Every Week
Whether you have a rooftop unit on your travel trailer, an underbunk system, or a basement air conditioner in your motorhome, these are the problems we see most often.
AC Runs but Won't Cool
The fan blows, but the air coming out is warm or barely cool. We test each component to find exactly what is going on.
AC Won't Turn On
Nothing happens when you flip the switch, no hum, no nothing. Could be a tripped breaker, bad thermostat, failed control board, or a wiring issue. We check your 12V and 120V systems to pinpoint the cause.
Short Cycling On and Off
Your AC starts, runs for a few minutes, then shuts off and tries again. This puts serious strain on the compressor.
Leaking Water Inside
Water dripping from the ceiling unit into your RV. Could be a clogged drain pan, a failed gasket, or frozen coils that melt and overflow. Catching it early prevents interior water damage.
Tripping the Breaker
The AC trips the breaker at the pedestal or in your RV panel. You just want it to work, we just make it work.
Loud or Strange Noises
Rattling, buzzing, grinding, or clicking that wasn't there before. New noises mean something changed, and it won't fix itself.
Rooftop, Underbunk, and Basement AC Units: We Service Them All
Rooftop Air Conditioners
Most RVs, travel trailers, campers, and fifth wheels have rooftop-mounted AC units. These sit on the roof and cool through ceiling vents or a ducted system. They're exposed to sun, rain, road vibration, and debris, all of which take a toll over time.
We service the full rooftop system: shroud, coils, capacitors, fan motors, compressor, gaskets, thermostats, and control boards. If the roof seal around your unit is failing, we address that too, before water damage starts.
Underbunk Air Conditioners
Some RVs mount the AC unit under a bunk or bed platform instead of on the roof. These underbunk units save roof space and reduce wind noise while traveling, but they're harder to access for service and still suffer the same component failures as rooftop models.
We diagnose and repair underbunk AC systems including the compressor, evaporator, control board, and ductwork that routes cool air through your RV.
Basement Air Conditioners
Some Class A motorhomes and higher-end RVs use basement-mounted AC systems. These units are tucked underneath and cool through a ducted system. They're quieter and more protected from the elements, but they still develop problems with compressors, control boards, and airflow.
Basement AC repair requires different access and diagnostic approaches than rooftop units. Our technicians have the training and experience to work on both configurations.
Brands We Service
Your RV air conditioner has a specific manufacturer, model, and set of components. We don't treat them all the same. We diagnose based on what's actually in your unit.
Repair or Replace: How to Know
Not every AC problem means you need a new unit, and we're not going to push you toward a replacement when a repair makes more sense. Here's the honest breakdown:
Repair Usually Makes Sense
Capacitor failure: the most common fix we do. Affordable and restores full cooling.
Fan motor replacement when the unit is otherwise healthy.
Thermostat or control board issues when the cooling system itself is fine.
Gasket replacement to stop water leaks without touching the AC system.
Replacement Usually Makes Sense
Compressor failure when the repair cost approaches the price of a new unit.
Unit is 10+ years old with multiple failing components.
Refrigerant leak in a sealed system where recharging is a temporary fix.
Repeated failures after previous repairs elsewhere.
You get accurate honest diagnostics. Not pressure, no upselling.
Proper Maintenance = Longer Life & Better Cooling
You get the most out of your RV air conditioner with regular maintenance. Follow these manufacturer-recommended guidelines:
Maintenance Schedule
- Weekly during use: Clean filters (manufacturers recommend this for optimal performance)
- Annually: Full AC service and cleaning (minimum once per year)
- High-dust environments: Service twice per year (dirt track racing, desert camping, dusty conditions)
- Ductwork: All ducts must be properly sealed—air leaks reduce cooling and strain the system
💡 Pro Tip: The Most Expensive Test
Just changing an air conditioner is the most expensive test. If the first one was working properly, the second one probably won't do any better.
Many cooling issues aren't the AC unit itself—they're ductwork sealing, insulation, undersized units, or electrical problems. That's why proper diagnosis matters. You save money when we fix the actual problem, not replace working parts.

Accurate Diagnosis First
We test components individually: capacitors, compressor, fan motors, voltage, amperage draw. You will know what we find, the actual failure, before we change anything.
Common Parts in Stock
We stock capacitors, fan motors, thermostats, and gaskets for Dometic, Coleman, and other popular brands. Many AC repairs are completed the same visit.
RV Air Conditioner Repair: Common Questions
A common cause is dirty evaporator or condenser coils, a failed capacitor, low refrigerant, or a compressor that's starting to fail. A failed capacitor is the most frequent low cost fix we see. It's an affordable repair that restores full cooling. Regardless we got your back and keep most parts in stock.
It depends on the problem and the age of the unit. Capacitor replacements, fan motor swaps, and thermostat issues are straightforward repairs that make financial sense if the unit is new enough. If the compressor has failed or the unit is 8+ years old there can be multiple problems that justify replacement as a better investment. We'll give you an honest assessment so you can make the right call.
Yes. We service and repair rooftop-mounted AC units (the most common type on all campers, travel trailers, fifth wheels, and motorhomes), underbunk units mounted under a bed platform or up on the wall like a window unit, and basement air conditioners found on some Class A motorhomes and a few 5th-wheels. We work on all major brands including Dometic, Coleman, Advent, and Furrion.
Costs vary depending on the problem. A capacitor replacement is on the lower end, while a full unit replacement costs more. We diagnose the actual problem first so you only pay for what's needed, not swapping parts hoping something works. Call us at (256) 571-9399 for a diagnosis.
We service all major RV air conditioner brands including Dometic, Coleman-Mach, Advent Air, Furrion Chill, and GE. Our RVTI-certified technicians are trained on both older and current model AC units.
That can be as simple as a bad wire nut or can also indicate a major unit failure. In those cases we will not speculate as doing so could cause harm. We test voltage, amperage draw, and electrical connections to find the real cause.
