Warm air from the vents
Refrigerant, compressor, capacitor and airflow checks to find why the system runs without cooling.
AC blowing warm, freezing up or dripping in the attic? HAXX repairs central air and mini-split cooling in Napa homes when the valley heats up.

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.
From June into October, Napa air conditioners carry most of the load on hot inland afternoons. The same few failures show up every heat wave.
Failed capacitors, contactors and condenser fan motors are the most common summer breakdowns and are usually fixed in one visit.
Dirty filters, blocked returns and tired blower motors freeze the coil. HAXX checks airflow before adding any refrigerant.
On older systems, the leak is located and repaired before recharging, so the problem does not return next month.
