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.
Inland summer heat waves are when tired compressors and capacitors tend to give out. Most central systems here sit beside the house or in the garage.
Failed capacitors, contactors and fan motors cause most summer breakdowns. HAXX tests them and replaces the failed part.
Ice on the lines usually points to low airflow, a dirty filter or a refrigerant leak. HAXX finds the cause before adding refrigerant.
Blocked drains in attic and garage air handlers can stain ceilings. HAXX clears the line and checks the pan and safety switch.
