Most RV air conditioning failures are electrical, not about refrigerant. Weak start and run capacitors, seized fan motors, bad control boards, and thermostat faults cause most no-cool calls. Each of those can be fixed at your site. A local pro starts at the thermostat and works through the 12-volt control side before anyone opens the rooftop unit. A wrong guess is how owners end up paying for a compressor they never needed.
Furnace work follows the ignition chain. A local pro tests the sail switch, limit switch, igniter board, and gas valve in order through the outside access panel. The common failure parts for popular rooftop and furnace models ride on the pros' trucks. So most climate calls get diagnosed and fixed in one visit.
RV A/C & Heating Repair in Schertz specifically
Rigs that sat through an assignment come back with seized fan motors and fouled coils from long idle time. That is a different failure than the worn-out-from-overuse pattern a local pro sees in the river parks.
Local conditions behind this pattern: long summer stretches over 100°f that hold rooftop a/c at full load.; strong spring hail. the san antonio area recorded four-inch stones in april 2024..
Symptoms owners describe
- A/C hums or clicks but the compressor never starts
- The fan runs but the air is not cold
- The unit trips the breaker or dims the lights at startup
- The furnace cycles but never lights
- Weak airflow or short cycling on hot afternoons
How the diagnosis works
- Check the thermostat call for cool or heat and the 12V controls
- Test capacitor microfarads against the rated values
- Measure compressor and fan amp draw under load
- Test the furnace ignition chain: sail switch, limit, igniter board
- Measure the temperature split between supply and return air
How the repair typically goes
- Replace failed start and run capacitors with the right rated parts
- Replace seized or worn fan motors and set the blade clearance
- Replace failed control boards and check the thermostat wiring
- Clean coils, filters, and drain paths to restore airflow
- Check final amp draw and temperature split before closing up
Repairable at your site
- Capacitor, fan motor, control board, and thermostat replacement
- Furnace ignition-chain repairs and burner cleaning
- Restoring airflow: coils, filters, and ducting at the plenum
When a shop or dealer is required
- Sealed-system refrigerant failures, where a new unit is usually cheaper
- Full duct replacement inside the roof cavity
- Structural repairs around a leaking rooftop-unit gasket with roof damage
Parts commonly involved
- Start and run capacitors
- Fan motors and fan blades
- Control boards and thermostats
- Furnace sail switches and limit switches
- Igniter boards and electrodes
What affects the price
Every visit starts with diagnosis and a written quote before repair work begins. These factors move the number:
- How hard the fault is to find (control side versus unit side)
- Parts needed and the unit brand and model
- Roof access and height
- Whether a new unit and a crane or lift is needed

Frequently asked questions
Why does my RV A/C run but not cool?
A few things commonly cause this. A weak run capacitor can stop the compressor from starting. Dirty coils and filters can block airflow. Low power at the campsite in summer can also be the cause. Losing refrigerant is less common than most owners think. A local pro tests the amp draw and temperature split at your site. That shows the real cause before any parts are suggested.
How is mobile RV repair priced?
You pay a service-call fee that covers travel and diagnosis. Then you pay for parts and labor on the repair you approve. A local pro gives you the diagnosis and a clear quote before any repair work starts. A pro never works on an open-ended okay. A few things change the price. Those are the part type, how hard the access is, and the size of the repair. Each service page explains this.
How quickly can a local pro get to me?
It depends on a few things. Your spot in the service area matters. So does how busy local pros are and whether your problem is an emergency. A local pro books scheduled visits for a time window and puts emergency calls first by safety. When you call, we take your request and share a real ETA from the pro instead of a blanket promise. We also follow up with you if the schedule changes.
