Heating and Cooling Services for Los Altos Homes

Most calls we get from Los Altos fall into two groups: something stopped working and needs repair, or an older system is due for replacement and the homeowner wants to understand the choices. We handle both. On a repair visit, we start by finding the actual cause, whether that's a failed part, a refrigerant problem, airflow restrictions or a thermostat issue. Then we explain what we found before any work begins.

Here is what we offer in Los Altos:

  • AC repair and AC installation
  • Heating repair and furnace repair
  • Furnace installation
  • Heat pump installation
  • Ductless mini-split installation
  • HVAC maintenance
  • Duct cleaning
  • Indoor air quality assessments and equipment

How the Local Climate Affects Your System

Los Altos shares the Santa Clara Valley's Mediterranean climate: dry summers and mild, damp winters. Because it sits on the northwest side of the valley, closer to the Bay than the inland and southern parts of the valley, summers here are usually less intense than they are farther south. That doesn't mean air conditioning goes unused. Warm stretches still happen, and an AC that has sat idle for months often shows its problems on the first hot day.

Winters are mild, but the damp chill makes heating a regular part of life from late fall into spring. Many homes run their heat in short cycles rather than long, hard stretches. That pattern is one reason heat pumps work well here. A single system can handle moderate heating and summer cooling without the extremes found in colder or hotter regions.

Dry summers also mean dust. Filters load up faster, and duct systems collect debris over time, which can reduce airflow and make equipment work harder than it should.

Replacing a Furnace: Bay Area Rules and Heat Pump Options

If your gas furnace is aging, it helps to know where regional rules are headed. 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 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, but 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.

On incentives: 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 date. Bay Area homeowners can still check BayREN and their local clean energy provider for heat pump and electrification incentives. Amounts and availability change with each funding cycle, so we confirm the current offer before including it in any quote.

Maintenance, Ductwork and Indoor Air

Routine maintenance is the simplest way to cut down on surprise breakdowns. A visit before the heating season and another before summer gives us a chance to clean components, check electrical connections and refrigerant levels, and catch worn parts early.

For homes where some rooms never feel comfortable, or where dust builds up quickly, we look at the ductwork and air quality too. Duct cleaning, sealing problem areas and better filtration can all help. In homes without ducts, or for an addition or converted garage, a ductless mini-split is often a practical way to add heating and cooling.

FAQ

Common questions

Don’t see your question? Call (669) 286-3980 and we’ll talk it through.

Do you serve all of Los Altos?

Yes. We serve homes in the 94024 ZIP code and the surrounding area, including Los Altos Hills, Mountain View, Palo Alto, Sunnyvale and Cupertino.

Do I have to replace my gas furnace because of the new Bay Area rules?

No. The Air District appliance rules don't require replacing working equipment. They apply only when a furnace or water heater fails or is replaced.

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

Often, yes. Mild, damp winters and dry summers suit heat pumps well, since one system can handle both heating and cooling. We'll look at your home and ductwork before recommending one.

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. Check BayREN and your local clean energy provider for current incentives. We confirm current offers before quoting them.

How often should I schedule HVAC maintenance?

Most homes benefit from a check before the heating season and another before summer. If you have a heat pump that runs year-round, regular service matters even more.

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

Yes. Ductless mini-splits work well for additions, converted garages and rooms the main system doesn't reach.
