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.
SAN RAMON DETAILSAir conditioning repair
Air conditioning repair
in San Ramon.
San Ramon sees triple-digit afternoons most summers. Air conditioners that coast through spring often fail when they run all day for a week straight.
01
No-start calls
Failed capacitors, contactors and fan motors account for many summer breakdowns. Common parts travel on the truck.
02
Frozen coils and weak airflow
Dirty filters, blocked returns and low charge freeze the coil. HAXX finds the cause instead of just thawing it.
03
Refrigerant leaks
Leaks are located and repaired before any recharge, so the system is not topped off only to fail again.

GOOD TO KNOW
AC Repair in San Ramon: questions, answered.
Why is my AC running but not cooling the upstairs?
Two-story San Ramon homes often have duct, return or zoning problems that leave the second floor hot. HAXX checks airflow at each register.
What causes the AC to stop working on the hottest days?
Heat stresses capacitors, contactors and compressors. Dirty outdoor coils make it worse by raising head pressure.
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.
