Types of RV Air Conditioners and the Repairs They Commonly Require

When you’re traveling in an RV, few things are more important to your comfort than a reliable air conditioning system—especially during hot summer months. Whether you’re parked at a scenic campsite in Florida or road-tripping through Arizona, your RV’s AC keeps the space livable and cool. But not all RV air conditioners are the same. Understanding the different types of RV ACs and the repairs they may require can help you make informed decisions about maintenance, replacement, or extended warranty coverage.

In this guide, we’ll break down the types of RV air conditioners, the most common problems they experience, and how those issues are typically repaired.

1. Roof-Mounted RV Air Conditioners

Roof-mounted ACs are the most common type found in RVs. They sit on top of the vehicle and push cool air downward into the living space. These units are ideal for larger RVs or travel trailers and are typically powered by shore power or a generator.

Popular Models:

• Dometic Brisk II

• Coleman Mach Series

• Furrion Chill

Common Repairs:

• Compressor Failure: The compressor is the heart of the AC. Over time, it can fail due to wear and tear or electrical issues. A bad compressor usually requires full replacement.

• Fan Motor Issues: If your fan isn’t circulating air, the motor may be worn out. Motor replacements are relatively common.

• Refrigerant Leaks: While RV AC units are sealed systems, leaks can still occur, especially in older models or after heavy use. Unfortunately, many RV ACs are not designed to be recharged, and this may require replacing the unit.

• Capacitor Failures: Start or run capacitors often go bad, resulting in humming noises or the unit not turning on at all.

• Dirty Coils and Filters: Poor cooling performance may simply be due to blocked airflow from dirty evaporator or condenser coils. Cleaning and routine maintenance can resolve this.

2. Ducted RV Air Conditioners

Ducted air conditioners are found in larger motorhomes and fifth wheels. These units distribute air through ceiling ducts, offering more even cooling throughout the RV.

Pros:

• Quieter operation

• Consistent temperature control

• Cleaner aesthetics (no bulky units inside)

Common Repairs:

• Duct Blockages: Reduced airflow might be due to a blocked or crushed duct. Technicians need to inspect the ductwork to locate the issue.

• Thermostat Malfunctions: Ducted systems rely on wall thermostats. When the thermostat fails, the system may cycle erratically or not turn on.

• Control Board Issues: The electronic control board may fail due to moisture, age, or power surges.

• Fan Blade Damage: If foreign debris gets into the duct system or rooftop unit, it can damage fan blades, requiring blade replacement or motor repair.

3. Non-Ducted RV Air Conditioners

Non-ducted AC systems blow air directly into the living space from a ceiling-mounted unit. These are most common in smaller RVs, camper vans, and travel trailers.

Key Benefits:

• Simpler installation

• Lower cost

• Ideal for single-room cooling

Common Repairs:

• Blower Motor Replacement: If the air is cool but not circulating, the blower motor may be the culprit.

• Control Panel Failures: Most non-ducted systems use onboard controls. If the panel is unresponsive, it may need to be replaced.

• Water Leaks: Improper installation or clogged drainage lines can cause water to leak into the RV interior.

4. Portable RV Air Conditioners

Portable AC units are less common but are used as supplemental cooling or in RVs without built-in AC. These units vent through a window or custom opening.

Common Repairs:

• Exhaust Hose Problems: Cracked or disconnected hoses reduce performance and can cause hot air to circulate inside.

• Drainage Issues: Portable units collect condensation in internal tanks that must be emptied or drained. Failure to do so can cause leaks or shutoff problems.

• Control Board Malfunctions: Just like built-in units, electronics can fail, especially in budget models.

5. Window-Mounted RV Air Conditioners

Window-mounted units are typically found in DIY builds or older RVs. They’re easy to install and replace but are less efficient than roof-mounted models.

Common Repairs:

• Bracket or Mount Failures: Movement during travel can loosen or damage window mounts.

• Thermostat Calibration: If your AC cycles on and off too frequently, the thermostat might be reading indoor temperatures incorrectly.

• Noise Issues: These units can vibrate more than others, leading to rattling or loud operation that may require tightening or dampening.

General RV AC Troubleshooting Tips

Whether you’re dealing with a ducted or non-ducted unit, here are a few general issues that affect all RV air conditioners:

1. Unit Not Turning On

• Check the power source: Ensure your RV is plugged into shore power or your generator is functioning.

• Reset breakers or fuses.

• Test the thermostat.

2. AC Blowing Warm Air

• Filters may be clogged.

• Refrigerant leaks could be the cause.

• The compressor might not be running.

3. Weak Airflow

• Obstructed vents or ductwork

• Worn blower motor

• Dirty fan blades or coils

4. Water Leaks Inside RV

• Clogged condensate drain line

• Improper installation angle

• Worn-out gaskets or seals

RV AC Maintenance to Avoid Repairs

Routine maintenance can help extend the life of your RV air conditioner and reduce the need for expensive repairs:

• Clean or replace air filters every month during heavy use

• Inspect and clean coils at least twice per season

• Tighten mounting bolts to prevent leaks and vibrations

• Check for insect nests in rooftop units

• Inspect wiring for signs of damage, corrosion, or overheating

Should You Repair or Replace Your RV AC?

In many cases, especially for older units or those out of warranty, replacing the AC may be more cost-effective than repairing it. Here’s a quick guide:

Protecting Your RV AC With an Extended Warranty

Because RV air conditioners are expensive to repair and replace—often costing $800 to $2,000 per unit—it’s smart to protect them with an extended RV warranty or service contract. These plans often cover:

• Compressor replacement

• Capacitor and motor repairs

• Thermostat issues

• Electrical failures

• Factory-installed AC systems

If your RV is still within the eligible model year and age range, a service contract can save you hundreds or even thousands of dollars over time.
