Heating and Cooling Services in Los Altos Hills

Our technicians drive out from San Jose for scheduled visits and repair calls throughout Los Altos Hills. Larger homes are common here, and many have more than one system, a mix of older and newer equipment, or rooms added over time that the original ductwork was never sized for. We look at the whole setup before recommending anything, so a fix in one part of the house doesn't create a problem in another.

  • AC repair and AC installation
  • Heating repair, furnace repair, and furnace installation
  • Heat pump installation for whole-home heating and cooling
  • Ductless mini-split installation for additions, offices, and rooms the ducts don't reach
  • HVAC maintenance visits before the heating and cooling seasons
  • Duct cleaning
  • Indoor air quality assessments and equipment

How the Local Climate Affects Your System

Los Altos Hills sits in the Santa Clara Valley, which has a Mediterranean climate: dry summers and mild, damp winters. Summer heat here is usually less intense than in the inland and southern parts of the valley, but warm stretches still put steady load on air conditioners, and homes with strong sun exposure or large windows can heat up quickly in the afternoon.

Winters rarely get severe, so many furnaces sit unused for months and then run hard on the first cold, wet nights. That stop-and-start pattern is when we tend to see ignition problems, dirty flame sensors, and blowers that struggle after a dusty summer. A tune-up in the fall and another before summer catches most of these issues before they turn into a no-heat or no-cool call.

Dry summers also mean dust and, in some years, smoky air. Good filtration and clean ducts matter more than many homeowners expect.

Replacing a Furnace? Know the Bay Area Rules

Under Bay Area Air District Rule 9-4, natural gas furnaces manufactured from 2029 onward must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when they replace a furnace after that date.

The rules do not require you to replace working equipment. They apply only when an existing furnace or water heater fails or is replaced. If your furnace runs well, there is no deadline forcing a change. If it's aging or needs frequent repairs, it can make sense to plan ahead rather than decide during an emergency.

Water heaters follow a separate rule. 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.

Heat Pumps, Mini-Splits, and Incentives

A heat pump handles both heating and cooling, which suits the valley's mild winters well. For homes with existing ducts, a central heat pump can often use much of the current duct system after we check sizing and condition. For converted garages, home offices, or rooms that never stay comfortable, ductless mini-splits add heating and cooling without new ductwork.

On cost help: the federal Energy Efficient Home Improvement 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 current heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before including it in a quote.

What to Expect When You Call

Tell us what's happening, such as no heat, warm air from the vents, short cycling, unusual noise, or rising energy use, and we'll schedule a visit. The technician diagnoses the problem, explains what they found in plain terms, and gives you options before any work begins. For replacements, we review your home's layout, existing equipment, and ductwork so the new system is sized for the house rather than guessed from the old unit's label.

FAQ

Common questions

Don’t see your question? Call (669) 274-2438 and we’ll talk it through.

Do you serve all of Los Altos Hills?

Yes. We serve homes throughout Los Altos Hills in the 94022 ZIP code, along with nearby Los Altos, Mountain View, Cupertino, Sunnyvale, and Saratoga.

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

No. The Bay Area Air District rules don't require replacing working equipment. They apply only when an existing furnace fails or is replaced, and the zero-NOx standard covers gas furnaces manufactured from 2029.

Is a heat pump a good fit for Los Altos Hills?

For many homes, yes. The Santa Clara Valley's mild, damp winters and dry summers suit heat pumps, which provide both heating and cooling. We check your ductwork and home layout before recommending a system.

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

No. The federal 25C credit covered qualifying heat pumps placed in service before December 31, 2025. You can check BayREN and your local clean energy provider for current incentives, and we confirm any current offer before quoting it.

How often should my system be serviced?

We recommend a maintenance visit before heating season and another before summer. Furnaces that sit idle for months often show ignition or flame sensor issues when they start back up.

Can you add heating and cooling to a room without ducts?

Yes. Ductless mini-splits work well for additions, converted garages, home offices, and other rooms your existing ducts don't reach.
