How the Local Climate Affects Your HVAC System

Los Altos sits in the Santa Clara Valley, which has a Mediterranean climate with dry summers and mild, damp winters. Homes here don't deal with the long freezes or muggy summers found in many other parts of the country. That doesn't mean heating and cooling equipment gets an easy ride.

Inland and southern parts of the valley run noticeably hotter in summer than areas near the Bay. Your home's location, its shade, and how much afternoon sun it gets all affect how hard your air conditioner works. Many AC systems here sit idle for months and then run hard during hot stretches. As a result, problems like weak capacitors, low refrigerant, and clogged condensate lines often show up on the first warm days of the year. In winter, heating demand is moderate but steady, and damp weather can expose leaky ducts, drafty returns, and furnaces that haven't been serviced in a while.

Planning a Furnace or Heat Pump Replacement

Bay Area Air District rules are changing what replacement looks like. 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 they replace a furnace 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. If your furnace runs well today, you can keep maintaining and repairing it. If it's aging or needs frequent repairs, consider now whether a heat pump would suit your home. Planning ahead means a sudden breakdown won't force a rushed decision.

If you also expect to replace your water heater, check the rules first. The zero-NOx date for small water heaters under Rule 9-6 was set for 2027. The Air District Board is considering amendments in November 2026 that could delay it, so check the current rule before you plan that project.

Incentives and Tax Credits: What Applies Now

The federal Energy Efficient Home Improvement Credit, known as 25C, covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date, so leave it out when you budget for a project today.

Los Altos homeowners can check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change with each funding cycle, so we confirm the current offer before we include it in a quote.

FAQ

Common questions

Don’t see your question? Call (669) 272-3348 and we’ll talk it through.

Do you serve all of Los Altos?

Yes. We serve homes throughout Los Altos, including the 94024 ZIP code, along with nearby Los Altos Hills, Mountain View, Sunnyvale, Cupertino, and Santa Clara.

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

No. The Bay Area Air District rules do not require replacing working equipment. They apply only when an existing furnace fails or is replaced. Gas furnaces manufactured from 2029 must meet a zero-NOx standard, which in practice points toward heat pumps for replacements after that date.

Is a heat pump a good fit for the Los Altos climate?

The Santa Clara Valley's mild, damp winters and dry summers suit heat pumps well, since one system handles both heating and cooling. We look at your home's layout, ductwork, and electrical setup 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, and it is not available for new installations after that date. Check BayREN and your local clean energy provider for current incentives.

Why does my AC have problems on the first hot day of the year?

Systems that sit unused for months can develop weak capacitors, low refrigerant, dirty coils, or clogged drain lines. A maintenance visit before summer helps catch these issues early.

What if a room in my house never stays comfortable?

A ductless mini-split is often a good solution for additions, converted garages, or rooms your existing ductwork doesn't serve well. We can also check your ducts for leaks or airflow problems.
