Central air conditioners, heat pumps in cooling mode and ductless systems. Most visits start with a full diagnostic so the repair targets the real cause.
Refrigerant, compressor, capacitor and airflow checks to find why the system runs without cooling.
Thermostat, breaker, disconnect, contactor and control-board testing.
Usually airflow or refrigerant charge. We fix the cause, not just thaw the ice.
Blower motors, dirty coils, clogged filters and duct problems that leave rooms warm.
Buzzing, grinding or burning smells checked before a small problem becomes a failed compressor.
Condensate drains, pans and pumps cleared and tested.
Calistoga has set temperature records above 110 degrees, and dozens of summer days reach 90 or more. Air conditioners here run long hours, and the weak parts show it.
Burned contactors and failed run capacitors cause most summer breakdowns and are usually replaced on the spot.
Ice on the lines often means low airflow or a refrigerant leak. HAXX locates the leak before recharging.
Dry seasons and wildfire smoke load filters and outdoor coils. A clean coil and fresh filter restore airflow and efficiency.
