The short answer
PrecisionFix repairs central AC, heat pumps and ductless systems in East Palo Alto, about 2 miles from our Palo Alto base. We diagnose the cause, explain your repair or replacement options before starting work, and offer 24/7 emergency service.
East Palo Alto sits close to the Bay, so many summer days stay comfortable without air conditioning. That makes it easy to forget about the AC until a warm stretch arrives and the system won't keep up. PrecisionFix HVAC Repair Service is based in Palo Alto, about 2 miles southwest of East Palo Alto. We repair central air conditioners, heat pumps and ductless systems in East Palo Alto homes. We find the actual cause, explain it in plain terms, and go over your options before any work starts.
Common AC Problems in East Palo Alto Homes
Air conditioners here often sit unused through the mild, damp winter, so problems tend to show up during the first hot week of the year. Outdoor units near the Bay also sit in moist air, which can wear on coil fins and electrical connections over time. These are the issues we're most often called about:
- Warm air from the vents while the outdoor unit runs, often caused by a failed capacitor, a worn contactor, or low refrigerant from a leak
- An outdoor unit that hums but whose fan won't spin
- Ice on the refrigerant lines or indoor coil, usually caused by restricted airflow or a low refrigerant charge
- Water pooling around the indoor unit from a clogged condensate drain
- Short cycling, where the system turns on and off every few minutes
- A breaker that trips when the AC starts
- A thermostat that doesn't call for cooling or reads the wrong temperature
What Happens During a Repair Visit
We start with the basics: thermostat settings, the air filter, and power to both the indoor and outdoor units. From there, we check the electrical components, measure refrigerant pressures and temperatures, inspect the coils, and confirm that air moves properly through the ducts and drain line. Once we know what failed and why, we explain the repair and your options before doing the work.
If the problem is a refrigerant leak, adding refrigerant alone only buys time. We'll tell you where the leak is, whether it's practical to fix, and what that involves.
Before you call, try a few quick checks. Make sure the thermostat is set to cool and has working batteries, look for a tripped breaker, and replace the filter if it's clogged. If the system still won't cool, turn it off so a small problem doesn't turn into a compressor failure.
Repair or Replace: What to Weigh
Most AC problems are worth repairing. Replacement makes more sense when the compressor has failed on an older system, when leaks keep coming back, or when the unit uses an older refrigerant that is getting harder to service. We'll give you a straight answer on which situation you're in.
Many East Palo Alto homes pair a central AC with a gas furnace. A heat pump handles both cooling and heating in one system. Under the Bay Area Air District's furnace rule, natural gas furnaces manufactured from 2029 must meet a zero-NOx standard. In practice, that points homeowners toward heat pumps when they replace a furnace after that date. The rule does not require you to replace working equipment. Still, if your AC fails and your furnace is aging, a heat pump is worth considering.
The federal 25C tax credit for heat pumps applied only to systems placed in service before December 31, 2025, and isn't available for new installations. You can still check BayREN and your local clean energy provider for current electrification incentives. Those programs change by funding cycle, so we confirm what's available before including it in a quote.
When to Call for Emergency Service
We offer 24/7 emergency service. A breakdown during a hot spell is urgent if anyone in your home is elderly, very young, or has a health condition affected by heat. Turn the system off and call right away if you notice any of the following:
- A burning smell or visible sparking at either unit
- A breaker that trips again after you reset it
- Water leaking through a ceiling or onto flooring
- Loud grinding, banging or screeching from the outdoor unit
