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.
Bay breezes keep Emeryville cooler than inland cities, but west-facing lofts and top-floor condos can overheat fast. When the system fails, those units get uncomfortable quickly.
A clogged drain or pump on an indoor unit can damage the ceiling of the neighbor below. HAXX clears the line and checks the safety switch.
HAXX locates the leak before recharging, rather than topping off a system that will be low again next season.
Failed capacitors, contactors and thermostats cause most no-start calls and are usually replaced on the first visit.
