Warm air from the vents
Refrigerant, compressor, capacitor and airflow checks to find why the system runs without cooling.

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.
Summer heat in the foothills pushes older systems hard. Most no-cool calls come down to a few worn parts or a refrigerant leak.
Weak capacitors, burned contactors and failed fan motors cause most no-start calls in hot weather. Common parts ride on the truck.
HAXX locates a refrigerant leak before recharging, so the system is not topped off only to fail again.
Clogged condensate lines, dirty filters and crushed ducts cause water damage and weak cooling. These are cleared and checked on the visit.

Yes. Monte Sereno's reach code does not apply to replacing or repairing existing equipment. HAXX repairs it as long as that makes sense.
Often a dirty coil, low refrigerant, a failed outdoor fan or restricted airflow. HAXX measures pressures and temperatures to find which.
Often, yes, in summer especially. Call and the team will confirm the earliest arrival window for your address.
Compare the diagnosed fault, the repair price and the system's age and refrigerant. HAXX shows both paths so you can choose.
