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.
East Palo Alto sits on the Bay side of the Peninsula, but inland heat waves still reach it. Systems that sit idle most of the year tend to fail when the first hot week arrives.
Weak capacitors, burnt contactors and seized condenser fan motors are common after months of little use.
HAXX locates the leak before adding refrigerant, then repairs the joint or replaces the coil if the leak is in the coil itself.
Clogged condensate lines in closet and attic units can overflow into ceilings and floors. Clearing and securing the drain is part of the repair.
