The short answer

Yes, PrecisionFix serves Los Altos Hills (ZIP 94022) from our Palo Alto base about 6 miles away, with repair, installation, maintenance, and 24/7 emergency service for heating and cooling systems.

PrecisionFix HVAC Repair Service works in Los Altos Hills, about 6 miles south of our base in Palo Alto. We handle heating and cooling repair, new system installations, routine maintenance, and indoor air quality work for homes throughout the 94022 ZIP code. Being close by means we know what Santa Clara County homes deal with: warm, dry summers, cool and damp winters, and equipment that can sit idle for months between seasons. If your heat or air conditioning quits at an inconvenient hour, we offer 24/7 emergency service.

How the Local Climate Affects Your HVAC System

The Santa Clara Valley has a Mediterranean climate. Summers are dry, and winters are mild but damp. Inland and southern parts of the valley run noticeably hotter in summer than areas near the Bay, so homes set back from the shoreline often see warmer afternoons than people expect.

That pattern is hard on equipment in specific ways. Air conditioners run hard during hot stretches and then sit unused for months, which is when weak capacitors, low refrigerant, and clogged condensate lines tend to show up. Furnaces and heat pumps get steady use on cool mornings and damp winter nights. Dry-season dust loads up filters and ducts, and the wet months can bring musty odors from ductwork or drain pans. We check for each of these during service calls.

Services We Offer in Los Altos Hills

Our technicians handle the full range of residential heating and cooling work:

  • AC repair and AC installation, including diagnosis of weak cooling, short cycling, and refrigerant leaks
  • Heating repair and furnace repair for gas furnaces that won't ignite, blow cold air, or shut off early
  • Furnace installation when a repair no longer makes sense
  • Heat pump installation for whole-home heating and cooling from one system
  • Ductless mini-split installation for additions, converted garages, and rooms ducts don't reach well
  • HVAC maintenance to catch small problems before peak season
  • Duct cleaning and indoor air quality work, including filtration upgrades

Planning a Furnace Replacement Under Bay Area Air District Rules

Under Bay Area Air District Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx emission 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. It applies only when an existing furnace fails or is replaced.

If your furnace is getting older, it helps to think through your options before it breaks down in January. We can look at your current system, your ductwork, and your electrical panel and explain what a heat pump would involve for your home, so you aren't making a rushed decision later.

On incentives: the federal 25C Energy Efficient Home Improvement Credit covered qualifying heat pumps placed in service before December 31, 2025, and it isn't available for new installations after that date. 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 a quote.

Heat Pumps and Mini-Splits for Hard-to-Condition Rooms

Many homes have a room that never feels right, such as an addition, a guest suite, or a space far from the main unit. Ductless mini-splits work well here because each indoor unit has its own controls and doesn't depend on existing ducts. A ducted heat pump can replace both a furnace and an AC in homes with ductwork in good condition. We'll tell you which approach fits your layout and why.

Maintenance Timing and Nearby Areas We Serve

For most homes in the area, we suggest a cooling tune-up in spring before the hot months and a heating check in fall before damp weather sets in. Heat pumps benefit from both, since they work year-round.

Beyond Los Altos Hills, we also serve Los Altos, Mountain View, Portola Valley, Sunnyvale, and East Palo Alto.

FAQ

Common questions

Don’t see your question? Call (650) 752-4497 and we’ll talk it through.

Do you serve all of Los Altos Hills?

Yes. We serve homes throughout the 94022 ZIP code in Los Altos Hills, about 6 miles south of our Palo Alto base.

Do you offer emergency HVAC service in Los Altos Hills?

Yes. We offer 24/7 emergency service for heating and cooling breakdowns.

Do I have to replace my gas furnace because of the 2029 rule?

No. The Bay Area Air District rules don't require replacing working equipment. The zero-NOx standard applies to furnaces manufactured from 2029 and affects you only when your existing furnace fails or is replaced.

Can I still get the federal tax credit for a heat pump?

The federal 25C credit covered qualifying heat pumps placed in service before December 31, 2025. It isn't available for new installations after that date. Check BayREN and your local clean energy provider for current incentives, and we'll confirm what's available before quoting.

Why does my AC struggle on the first hot days of summer?

Systems that sit idle through the mild, damp winter often have dirty filters, weak capacitors, or clogged drain lines that show up once the heat arrives. A spring tune-up catches most of these early.

Is a ductless mini-split a good fit for an addition?

Often, yes. Mini-splits don't need ductwork and give the room its own controls, which makes them a practical option for additions and spaces your main system doesn't reach well.
