HVAC Repair and Installation in Hillsborough, CA

The short answer

PrecisionFix HVAC Repair Service works on heating and cooling systems in Hillsborough, a town in San Mateo County about 13 miles northwest of our Palo Alto base. We serve homes throughout the 94010 ZIP code. We handle furnace and AC repair, heat pump and mini-split installation, routine maintenance, and indoor air quality work. If your system stops working at night or on a weekend, we offer 24/7 emergency service. This page covers how the local climate affects your equipment, what Bay Area air rules mean for your next furnace or water heater, and how to get the right kind of help.

How the Peninsula Climate Shapes Your HVAC Needs

The Bay Area has a Mediterranean climate, with dry summers and mild, damp winters. Areas closer to the Bay usually stay cooler in summer than the inland and southern parts of the Santa Clara Valley. As a result, many Hillsborough households lean more on heating than on air conditioning over the course of a year.

Mild weather doesn't mean you can ignore your equipment. A furnace that runs on and off through a long, damp winter collects dust on its burners and filters. An AC system that sits idle for months can have trouble when a warm spell arrives. Damp winter air can also add to indoor humidity and stale air, which is where duct cleaning and indoor air quality work can help.

Services We Offer in Hillsborough

We work on most residential heating and cooling setups, from a single furnace to a home with several zones or a mix of ducted and ductless equipment. If your home has more than one floor or a separate living space, we can help you work out whether a central system, a heat pump, or ductless mini-splits fits each area best.

  • Heating repair and furnace repair, including ignition, airflow, and thermostat problems
  • AC repair for systems that blow warm air, short-cycle, or won't start
  • Furnace installation and AC installation when repair no longer makes sense
  • Heat pump installation for heating and cooling in one system
  • Ductless mini-split installation for additions, converted garages, or rooms without ducts
  • HVAC maintenance to keep equipment ready for each season
  • Duct cleaning and indoor air quality improvements

Bay Area Air Rules and Your Next Furnace

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. If your furnace is getting older, it helps to start thinking now about whether a heat pump suits your home, so you aren't making the choice in a hurry after a breakdown.

These rules do not require you to replace working equipment. They apply only when an existing furnace or water heater fails or is replaced. Water heaters follow a separate timeline. The zero-NOx date for small water heaters under Rule 9-6 was set for 2027, and the Air District Board is considering amendments in November 2026 that could delay it. Check the current rule before you plan a water heater replacement.

Heat Pump Incentives: What's Current

The federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. 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 we include it in any quote.

FAQ

Common questions

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

Do you serve all of Hillsborough?

Yes. We serve homes throughout the 94010 ZIP code, along with nearby San Carlos, Redwood City, Woodside, Atherton, and Menlo Park.

Do I have to replace my gas furnace because of the new Air District rules?

No. The Bay Area Air District appliance rules do not require replacing working equipment. They apply only when an existing furnace or water heater fails or is replaced.

Is a heat pump a good fit for Hillsborough's climate?

Often, yes. With mild, damp winters and relatively moderate summers, many homes here can use a heat pump for both heating and cooling. We look at your home's layout, ductwork, and comfort needs before recommending one.

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, and isn't available for new installations after that. Check BayREN and your local clean energy provider for current incentives. We confirm what's available before quoting.

Do you offer emergency HVAC service in Hillsborough?

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

How often should I schedule HVAC maintenance?

Most homes benefit from a check before the heating season and another before warm weather, especially if one system handles both heating and cooling.
