Expert repair for ducted & non-ducted roof-mounted air conditioners. Dometic Brisk Air, Dometic Penguin, Coleman, GE, Furrion. RVTI-certified technicians.
Most RVs, campers, and motorhomes use roof-mounted air conditioners. Whether you have a ducted system with vents throughout your RV or a non-ducted free-blow unit, you get accurate diagnosis and genuine repairs from RVTI-certified technicians who've been servicing North Central Alabama RVs since 1993.
Ducted roof-top AC systems distribute cool air through ductwork and vents throughout your RV. You'll almost always have a wall-mounted thermostat controlling temperature. While there are a few ducted systems that do not have a wall thermostat, they are rare. You will experience a more even cooling and better circulation when properly installed and sealed.
Non-ducted systems blow air directly down from the ceiling-mounted AC unit. Almost exclusivly the controls are on the unit itself rather than a wall thermostat. Simpler design with fewer components to maintain.
Key identifier: No ducts through out the celing and air blows from just one location.

New market entries & various manufacturers
Many new brands have entered the market—most without replacement parts support. As RV AC experts, the brand doesn't matter. We can diagnose and help with any system.
RV feels warm even with AC running? Could be:
We diagnose the root cause—not just the symptoms.
AC completely dead? Common causes:
Systematic electrical diagnosis finds the problem fast.
Water dripping from ceiling or vents?
We locate the source and fix it permanently.
Ice forming on AC unit or vents?
Proper diagnosis prevents recurring freeze-ups.
Loud rattling, grinding, or buzzing?
We identify noise sources and resolve them.
AC turns on and off repeatedly?
Short cycling wastes power and wears components.
Before assuming your AC needs replacement, run this simple test to determine if the unit itself is working properly.
✓ If difference is 16°F or more → AC is working properly
The air conditioner unit itself is doing its job. If RV isn't cool enough, the issue is elsewhere (ductwork sealing, insulation, undersized unit, etc.)
✗ If difference is less than 16°F → AC needs service
The unit isn't cooling air adequately. Could be dirty coils, failed compressor, or any number of other AC-specific issues requiring professional diagnosis.
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 RV cooling complaints aren't the AC itself—they're ductwork not sealed, poor insulation, undersized units, or electrical issues. Proper diagnosis saves you money by fixing the actual problem, not replacing working parts.
You extend your AC's life and maintain peak cooling performance with regular maintenance. Manufacturers recommend this schedule:
Clean air filters. This is the #1 manufacturer recommendation. Dirty filters restrict airflow, reduce cooling, and cause freeze-ups.
Takes 5 minutes. Remove filter, rinse with water, let dry, reinstall. Some RVers keep spare filters to swap while one dries.
Full AC service minimum once per year. Professional cleaning of coils, inspection of all components, electrical testing, ducts, and refrigerant check.
Best done before camping season starts (March-April) so you're ready when temps rise.
Service twice per year or more if you have inside pets or if you camp in dusty conditions like dirt track racing or dusty locations.
Dust clogs coils faster, reducing efficiency and potentially causing premature failure.
All ducts must be properly sealed. Air leaks reduce cooling capacity and strain the AC, causing premature failure.
If you have ducted AC, inspect ductwork annually. Your benifit will be clear when its hot and you not.
Depends on the issue and age. Capacitors, thermostats, and minor repairs are usually cost-effective. If a compressor fails or it developed a refrigerant leak, replacement may make more sense. You get accurate information allowing you to make the best decision for your situation, no pressure either way.
Yes there are upgrades available and newer models are usually quieter. However, proper ductwork sealing often reduces noise significantly on existing units. We can discuss options, sometimes the noise issue is fixable without replacing the entire AC.
Mini-splits are NOT built for travel vibrations and road shock. They are viable if your RV remains permanently stationary. You will get better service and air conditioning from a properly installed and servcied ducted ac, a mini-split by design cannot circulate are from other rooms. For RVs that travel, you will appreciate a proper installs and potentially upgrading to a quieter roof-top unit are better solutions.
We stock most parts for Dometic, Coleman,GE, Furrion, and many other major brands. For less common parts, we can order direct from manufacturers for quick turnaround. Generally you wont have to wait long for repairs even if we need to order parts.
