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.
LOS ALTOS HILLS DETAILSAC repair for
AC repair for
hillside homes.
Sun-exposed slopes and big glass walls push cooling systems hard on hot afternoons. Large homes often split cooling across two or three systems, and one usually fails first.
01
Multiple condensers
HAXX tests every outdoor unit on the property, so a weak second system is caught before the next heat wave.
02
Attic and crawlspace equipment
Air handlers in attics and under raised floors get clogged drains and dirty coils. Both are checked on a cooling call.
03
Electrical side
Capacitors, contactors, disconnects and tripped breakers cause many no-cool calls. HAXX is licensed to repair all of them.

GOOD TO KNOW
AC Repair in Los Altos Hills: questions, answered.
Can you repair an older AC in Los Altos Hills?
Yes. HAXX repairs existing central and ductless systems and tells you when a part is no longer worth replacing.
My AC freezes up. What causes that?
Usually low airflow from a dirty filter or coil, or a low refrigerant charge from a leak. HAXX tests both before recommending a fix.
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.
