HVAC Services We Offer in Los Altos Hills
Most calls we get fall into two groups: something stopped working and needs repair, or a homeowner is planning an upgrade. We handle both. When you call about a repair, a technician diagnoses the problem first and explains what they found before any work starts, so you can decide whether a repair or a replacement makes more sense for your system.

What the Local Climate Means for Your System
The Santa Clara Valley has a Mediterranean climate: dry summers and mild, damp winters. In practice, that means your cooling equipment does most of its hard work during summer heat spells, while your heating system runs mostly on cool mornings and evenings rather than through long, deep freezes.
Summer temperatures also vary across the valley. Inland and southern areas run noticeably hotter than places near the Bay, so the right equipment size for one home isn't automatically right for another a few miles away. We size systems based on your house itself, including its layout, insulation, windows, and sun exposure, instead of using a rule of thumb.
Because winters here are mild, a heat pump can often handle both heating and cooling for a home. Damp winter weather is also a good reason to keep an eye on ventilation and filtration, which we cover as part of our indoor air quality work.
Replacing a Furnace: Bay Area Air District Rules
If your gas furnace is getting older, it helps to know where the regional rules stand. Under Bay Area Air District Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx emission standard. When a furnace is replaced after that date, that standard generally points homeowners toward heat pumps.
These rules do not require you to replace equipment that still works. They apply only when an existing furnace or water heater fails or is replaced. If your furnace is running well, regular maintenance is a reasonable way to keep it going while you plan ahead.
Water heaters follow a separate rule. 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. If a water heater replacement is on your list, check the current rule before you commit to a plan.
Heat Pumps, Ductless Systems, and Incentives
A heat pump heats and cools with one system. If your home already has ductwork in good shape, a ducted heat pump can often connect to it. For additions, converted garages, rooms that never stay comfortable, or homes without ducts, a ductless mini-split lets you heat and cool specific spaces without running new ductwork.
On incentives: the federal Energy Efficient Home Improvement Credit (25C) 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 current heat pump and electrification incentives. Amounts and availability change with each funding cycle, so we confirm the current offer before including it in a quote.
Maintenance, Duct Cleaning, and Indoor Air Quality
Routine maintenance gives a technician the chance to catch worn parts, dirty coils, and airflow problems before they turn into a breakdown on the hottest or coldest day of the year. Scheduling a tune-up of your cooling system before summer and your heating system before winter is a simple habit that suits the local climate.
Duct cleaning and indoor air quality work focus on what you breathe. Depending on your home, we may recommend better filtration, sealing leaky ducts, or ventilation changes that help manage dust and damp-season moisture.
