PrimeAir HVAC Repair Service works with homeowners in Highlands, the unincorporated community in San Mateo County about 16 miles west of our base in Fremont. We handle heating and cooling repair, new system installation, routine maintenance, and indoor air quality work. When a system quits at an inconvenient hour, we offer 24/7 emergency service. This page covers what we do in Highlands, how the local climate shapes your heating and cooling needs, and what to know about current Bay Area rules before you replace equipment.
Serving Highlands and Nearby Peninsula Communities
Highlands sits roughly 16 miles west of Fremont, so our technicians can reach your home without a long wait. Because it is an unincorporated part of San Mateo County, county rules apply to permitted work such as new system installations. We take that into account when we plan your project.
We also work throughout the surrounding area, so if you have family or a second property nearby, the same team can help there too.

Heating Repair for Mild, Damp Winters
Like much of the Bay Area, this part of the Peninsula has mild, damp winters rather than hard freezes. Your heater may not run around the clock, but it runs often enough on cool mornings and rainy evenings that problems tend to show up the first chilly week of the season. Common calls include furnaces that won't ignite, blowers that run without producing heat, short cycling, and odd smells when the system starts up.
We repair gas furnaces and heat pumps and will tell you plainly whether a repair makes sense or whether the equipment is near the end of its useful life. If a replacement is the better option, we can install a new furnace or a heat pump, depending on your home and your goals.
Cooling for Dry Summer Days
Summers here are dry, and while areas closer to the Bay generally stay cooler than inland parts of the region, warm stretches still happen. Many older homes were built with little or no cooling, and upstairs bedrooms can get uncomfortable on hot afternoons.
We repair central air conditioners and install new AC systems. For homes without ductwork, or for rooms that never cool evenly, a ductless mini-split can be a practical fix. A heat pump is another option worth considering because it provides both cooling in summer and heating in winter from one system.
Planning a Replacement Under Current Bay Area Rules
Highlands is covered by the Bay Area Air District, and its appliance rules affect future replacements. Under 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 a furnace is replaced after that date. 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 have their own 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 planning a water heater replacement.
On incentives: the federal 25C tax credit covered qualifying heat pumps placed in service before December 31, 2025, and it is not 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 change by funding cycle, so we confirm the current offer before including it in a quote.
Maintenance, Duct Cleaning, and Indoor Air Quality
Damp winters and dry, dusty summers both affect the air inside your home. Regular maintenance keeps your system running efficiently and helps us catch worn parts before they fail. Duct cleaning removes built-up dust and debris, and our indoor air quality services address filtration, humidity, and airflow.
- Seasonal HVAC maintenance for heating and cooling systems
- Duct cleaning to clear dust and debris from supply and return lines
- Indoor air quality improvements, including filtration and humidity control
