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.
Campbell condensers usually sit in side yards of 1950s to 1970s tract homes, with the coil and furnace in the attic or a hall closet. Hot spells expose the weak parts.
Failed capacitors, contactors and fan motors account for many summer breakdowns and are usually replaced on the first visit.
HAXX locates a refrigerant leak before recharging, and recommends a coil replacement only when the leak can't be repaired.
Clogged filters, crushed flex duct and dirty coils cause many freeze-ups in older attic systems.
