FAQ
Frequently asked questions
Low refrigerant from a leak, a failed compressor or clutch, a blocked condenser, a bad pressure switch or an electrical fault are the most common causes. We test pressures and electrical circuits to find the real problem.
If the system is low, there is a leak somewhere. We find and repair the leak first so the recharge lasts, instead of adding refrigerant that leaks out again.
Yes. We repair heater valves, heater cores, blend doors, blower motors, resistors and controls so your cab heats and defrosts properly.
