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.
DUBLIN DETAILSKeeping Dublin
Keeping Dublin
homes cool.
Tri-Valley heat waves can bring several 100-degree days in a row, and PG&E has warned of heat-related outages during them. That is when weak parts fail.
01
Upstairs too hot
Two-story homes in Positano and Tassajara Hills often fight hot upper floors. HAXX checks airflow, ducts and zoning, not just refrigerant.
02
No-start calls
Failed capacitors, contactors and fan motors are the usual July problems and are often fixed on the first visit.
03
Leaks found first
If refrigerant is low, HAXX locates the leak before recharging so you are not paying for the same refill next summer.

GOOD TO KNOW
AC Repair in Dublin: questions, answered.
Why is my AC running but not keeping up on hot Dublin afternoons?
Common causes are a dirty coil, low refrigerant, a weak capacitor or undersized ducts. HAXX measures temperatures and pressures to find which one.
Do you repair AC in older West Dublin homes?
Yes. HAXX services systems in the 1960s tracts as well as newer east Dublin subdivisions.
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.
