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.
Most Milpitas summer days reach the low to mid 80s, with occasional hotter spells. Those stretches are when aging systems tend to quit.
Failed capacitors, contactors and fan motors cause most hot-day breakdowns. Common parts travel on the truck.
HAXX locates and repairs the leak first rather than topping off refrigerant that will escape again.
Clogged condensate lines and dirty coils in attic units lead to water damage and frozen lines. Both are cleared and tested.
