RV A/C Cleaning & Replacement

Roof unit sweating like it's mid-summer in Arizona, but you're just getting warm air? We swoop in — dirty coils? Blasted clean. Capacitors acting up? Replaced — no drama. Compressor windings? Double-checked and good to go. Fan motor? Spinning like a champ at full RPM.

Massachusetts summers can be brutal, and a properly functioning A/C is the difference between a relaxing trip and a miserable one. At Clean Slate RV Repair, we provide comprehensive air conditioning services including deep cleaning, repair, and full unit replacement.

Want an upgrade? We drop in anything from 12,000 to 18,000 BTU with a soft-start kit — your entire electrical system stays happy, no bog-downs. Thermostat goes digital (bye-bye guesswork), vents get balanced — no hot zones, no ice art. We hand you the fun facts: amps, temp drops, RPMs. Your rig? Cool, quiet, and basically a rolling fridge.

Common RV A/C Problems We Fix

RV air conditioners work hard — mounted on the roof, exposed to sun, rain, and road vibration year-round. Here are the most common issues we see:

Running but not cooling: Dirty evaporator and condenser coils are the #1 cause. Years of dust, pollen, and debris restrict airflow and reduce cooling capacity dramatically. Our deep cleaning service restores performance without replacing parts.

Not turning on at all: Usually a failed capacitor (run or start), a tripped breaker, or a faulty thermostat. Capacitors are the most common failure point in rooftop A/C units and are an easy, affordable fix.

Short cycling: The compressor turns on and off rapidly, which can be caused by low voltage, a failing compressor, or a dirty condenser coil causing the unit to overheat.

Freezing up: Ice forming on the evaporator coil indicates restricted airflow (dirty filter or coils), low ambient temperature operation, or a refrigerant issue in sealed systems.

Excessive noise or vibration: Worn fan motor bearings, loose mounting bolts, or a damaged fan blade can cause your A/C to sound like a helicopter. We diagnose and fix the source.

Our Deep Cleaning Service

Our A/C deep cleaning is one of our most popular services — and for good reason. Most RV owners don't realize how much performance they're losing to dirty coils.

We remove the shroud, pull the filters, and thoroughly clean both the evaporator (inside) and condenser (outside) coils using professional-grade coil cleaner and low-pressure rinsing. We also clean the drain pan, check the drain tube for clogs, and inspect the gasket seal between the unit and the roof.

After cleaning, we test capacitors, fan motor amperage, and compressor operation. We check the thermostat calibration and inspect all wiring connections. The result? Dramatically improved airflow, lower energy consumption, and colder air output.

A/C Upgrades & Replacement

If your unit is beyond repair or you're looking to upgrade, we install new rooftop A/C units from all major manufacturers including Dometic, Coleman, and Advent. We'll help you choose the right BTU capacity for your rig and ensure a proper, leak-free installation.

We highly recommend adding a soft-start kit with any new installation. Soft-start devices reduce the startup surge from 40+ amps to under 20 amps, allowing you to run your A/C on a 30-amp circuit, a smaller generator, or even an inverter setup. It also extends compressor life.

Digital thermostat upgrades give you precise temperature control, programmable settings, and better cycling — no more guessing or constantly adjusting.

Brands & Models We Service

We service all major RV A/C brands, including Dometic (Brisk, Penguin), Coleman-Mach, Advent Air, and Furrion. Whether you have a 13,500 BTU standard unit or a 15,000 BTU ducted system, we have the knowledge to diagnose and repair it.

We're experienced with both ducted and non-ducted configurations, single and dual A/C setups, and heat pump models that provide both cooling and heating.

A/C Maintenance Tips

Keep your RV A/C running efficiently with these simple maintenance practices:

Clean or replace the air filter monthly during heavy use. A clogged filter is the easiest problem to prevent and the most common cause of reduced cooling.

Have the coils professionally cleaned at least once a year — ideally before summer. This single service can restore up to 30% of lost cooling capacity.

Inspect the roof gasket seal annually. A deteriorated gasket allows rainwater to leak around the A/C unit and into your ceiling.

Don't run the A/C with windows or doors open. It overworks the compressor and can cause freezing of the evaporator coil.
