Signs your RV A/C needs service
- The unit runs but the air coming out is barely cooler than the cabin
- The compressor hums, clicks, and shuts off instead of starting
- The fan spins but the compressor never kicks in at all
- Water dripping down an inside wall or pooling around the ceiling shroud
- The breaker trips or the unit browns out every time it cycles on
- A grinding, rattling, or squealing noise from the roof
What the service covers
Full diagnostic
Voltage at the unit, amp draw, capacitor test, thermostat and control board check, and a temperature split across the coil to confirm whether the problem is electrical, airflow, or a sealed-system failure.
Capacitors, relays, and control boards
A hard-start capacitor or a failed relay is the most common reason a unit hums and refuses to start. These are inexpensive parts and a same-visit repair in most cases.
Fan motors and blower wheels
Seized condenser fans, worn blower bearings, and out-of-balance wheels get replaced with the correct part for your unit rather than a universal substitute.
Coil cleaning and airflow correction
A packed condenser coil or a collapsed return-air filter mimics a dying compressor almost exactly. Cleaning and restoring airflow is always the first thing checked before anything expensive gets recommended.
Gasket and leak repair
The foam gasket between the unit and the roof compresses and hardens, and the resulting leak shows up as staining on the ceiling around the shroud. Replacing it is straightforward once the unit is lifted.
Complete unit replacement
When a sealed system has failed, replacement is the honest answer — RV rooftop units are not field-serviceable for refrigerant. New unit sourced, old one removed, roof resealed, and the thermostat matched.
Why RV A/C fails so often in Central Texas
A rooftop RV air conditioner is sized to pull the cabin roughly twenty degrees below outside air. That math works fine in most of the country. On a 102-degree Kyle afternoon with the sun beating on an aluminum roof, a perfectly healthy unit is already at its limit — so a unit that is even slightly compromised falls off a cliff.
The result is that most of the "my A/C died" calls that come in during July and August are not dead compressors at all. They are dirty condenser coils, weak capacitors, restricted return air, or low incoming voltage from a long extension cord or a tired pedestal at an RV park. All four are fixable on site, and none require replacing the unit.
Diagnose before you replace
A new rooftop unit is one of the more expensive things you can buy for an RV, and it is regularly sold to owners whose old unit needed a thirty-dollar part. Every A/C call here starts with measurement — voltage, amperage, and a temperature split — before any recommendation gets made.
If the sealed system really is finished, you get told plainly, along with what the replacement costs before any work starts. If it is a capacitor, you pay for a capacitor. Upfront pricing is given before the wrench comes out either way.
