Warm air from the vents
Refrigerant, compressor, capacitor and airflow checks to find why the system runs without cooling.
AC not cooling, freezing up or tripping a breaker? HAXX repairs central air and ductless systems in Piedmont, from hillside homes to Lower Piedmont.
Serving Lower Piedmont, Upper Piedmont, Baja Piedmont, the Sea View Avenue area and Estates Drive and the rest of Piedmont. Share your address to confirm availability.

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.
Many Piedmont houses added air conditioning decades after they were built, so units sit in tight attics, basements or side yards. Hot spells expose weak parts quickly.
HAXX locates the leak first. Adding refrigerant to a leaking coil just sets up a repeat failure.
Failed capacitors and contactors cause most no-start calls in hot weather, and are usually replaced on the first visit.
Clogged condensate lines and dirty filters cause water damage and frozen coils, a real risk in finished attics and upper floors.

“Our commercial building had several HVAC problems, and their team carefully diagnosed each unit, explained the available options, and never pressured us into unnecessary replacements. They worked hard to repair what could be repaired and kept us informed throughout the process.”
Brand, model and what it is doing. Photos of the label or error code help.
The technician tests the system and finds the cause, not just the symptom.
You see the repair price before work starts, and the options if a repair is not worth it.
The repair is completed and tested, or scheduled once the part arrives.

Usually a clogged condensate drain, a cracked pan or a frozen coil thawing. HAXX clears the drain, checks the pan and finds why the coil froze.
Often, yes. HAXX tests the system and tells you whether a repair is sound or the unit is near the end of its life.
