Both can cause poor cooling, but there are key differences. A refrigerant leak often shows as ice on refrigerant lines, a hissing sound, or a gradual loss of cooling power. A wiring or thermostat issue might cause the system to short cycle, not turn on at all, or display error codes. Our San Antonio technicians use specialized tools like leak detectors and multimeters to pinpoint the exact cause quickly and accurately.

Absolutely. Incorrect or faulty thermostat wiring can send the wrong signal to your HVAC system, telling it the set temperature is never reached. This forces the unit to run non-stop, wasting energy and straining components. We'll carefully inspect your wiring, ensure proper connections at the thermostat and air handler, and calibrate the system so it cycles on and off as intended for efficient cooling.

Simply adding refrigerant without fixing the leak is a temporary, ineffective solution. First, refrigerant leaks are illegal due to environmental regulations. More importantly, the leak will continue, causing the same problem and wasting your money. Our process involves using electronic detectors or UV dye to find the exact leak location, performing a proper repair, and then recharging the system to the manufacturer's exact specification for optimal performance and efficiency.
