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.
Oakley's summers regularly push air conditioners to run for hours without a break. The parts that fail are predictable, and most can be replaced on the first visit.
Burned contactors, swollen capacitors and failed condenser fan motors are the usual causes when the outdoor unit hums but does not run.
Ice on the line set usually points to low airflow or low charge. HAXX checks filters, blower and ducts before touching refrigerant.
HAXX locates and repairs the leak first, then charges to the manufacturer's specification rather than topping off every summer.
