The short answer
PrecisionFix repairs furnaces, heat pumps, and other heating systems in Los Altos Hills, CA, with 24/7 emergency service from our nearby Palo Alto base. Bay Area Air District rules don't require you to replace a working furnace, so repair is often a sensible choice when the system is otherwise sound.
When the heat stops working in your Los Altos Hills home, you want a clear answer about what failed and what it will take to fix it. PrecisionFix HVAC Repair Service is based in Palo Alto, about 6 miles north, and we repair furnaces, heat pumps, and related heating equipment for homeowners throughout the 94022 ZIP code. We explain what we find in plain terms, show you the failed part when we can, and lay out your options before any work starts. We also offer 24/7 emergency service for nights when waiting until morning isn't practical.
Heating Problems We Fix in Los Altos Hills Homes
Most heating calls come down to a handful of causes. Some are quick fixes. Others point to a worn component that has been struggling for a while. We test the system rather than guess, so you're not paying to replace parts that were working fine.
- Furnace won't ignite, or lights and then shuts off
- Blower runs but the air coming from the vents is cool
- Heat pump stuck in defrost, short cycling, or not switching to heat
- Thermostat not calling for heat or reading the wrong temperature
- Rooms that stay noticeably colder than the rest of the house
- Banging, squealing, or rattling from the furnace or air handler
- Burning or electrical smells when the heat first comes on
What to Expect From a Repair Visit
We start by asking what you've noticed: when the problem began, whether it comes and goes, and any sounds or smells. Then we check the thermostat, power and gas supply, ignition and flame sensing, airflow, filters, blower motor, and safety controls. On heat pumps, we also check refrigerant-side operation and the defrost cycle.
Once we know the cause, we tell you what needs to be fixed and what can wait. If a part is near the end of its life but still working, we'll say so and let you decide. We don't start repairs until you've approved the work.
Repair or Replace? What Bay Area Air Rules Mean for You
Many homeowners have heard that gas furnaces are being phased out. Here is what the rules actually say. Under Bay Area Air District Rule 9-4, natural gas furnaces manufactured from 2029 on must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when a furnace is replaced after that date.
These rules don't require you to replace working equipment. They apply only when an existing furnace fails or is replaced. If your furnace is otherwise in good shape, repairing it is a reasonable choice, and we won't push you toward a new system you don't need.
If you are weighing a heat pump, keep in mind that the federal 25C tax credit covered qualifying heat pumps placed in service before December 31, 2025, and it isn't available for new installations after that. Bay Area homeowners can still check BayREN and their local clean energy provider for heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before including it in any quote.
Keeping Heat Reliable Through Mild, Damp Winters
The Santa Clara Valley has a Mediterranean climate with dry summers and mild, damp winters. Because heating systems here may sit idle for months, problems often show up on the first cold evening of the season. Dust on burners, a weak igniter, or a clogged filter can all surface at once.
Running your heat briefly in early fall, before you really need it, gives you time to schedule a repair at your convenience instead of on a cold night. Changing the filter regularly and keeping the area around the furnace or outdoor heat pump unit clear also help the system run as designed.
