AC problems
we fix.
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.
AC will not turn on
Thermostat, breaker, disconnect, contactor and control-board testing.
Frozen coil or ice on lines
Usually airflow or refrigerant charge. We fix the cause, not just thaw the ice.
Weak airflow
Blower motors, dirty coils, clogged filters and duct problems that leave rooms warm.
Strange noises or smells
Buzzing, grinding or burning smells checked before a small problem becomes a failed compressor.
Water around the indoor unit
Condensate drains, pans and pumps cleared and tested.
ST. HELENA DETAILSAC repair for
AC repair for
St. Helena summers.
Upper Napa Valley summers bring long runs of hot, dry days. Equipment that limps through spring often fails in the first heat wave.
01
No-start calls
Failed capacitors, contactors and fan motors account for many summer breakdowns. HAXX carries common parts on the truck.
02
Frozen coils
Restricted airflow, dirty filters and low refrigerant cause ice on the indoor coil. HAXX finds the cause rather than just thawing it.
03
Leaks and charge
Before adding refrigerant, the technician locates the leak and repairs the coil or line set when that is the right fix.

GOOD TO KNOW
AC Repair in St. Helena: questions, answered.
Why is ice forming on my AC lines?
Usually low airflow from a clogged filter or blower problem, or low refrigerant from a leak. Turn the system off and HAXX will diagnose it.
Do you repair ductless air conditioners in St. Helena?
Yes. HAXX repairs wall, ceiling cassette and ducted mini-split systems from all major brands.
Can you come the same day?
Often, yes, in summer especially. Call and the team will confirm the earliest arrival window for your address.
Should I repair or replace my AC?
Compare the diagnosed fault, the repair price and the system's age and refrigerant. HAXX shows both paths so you can choose.
