Heating and Cooling Services We Offer in Los Altos Hills
Most calls we get start with a specific problem. The house isn't cooling, the heat smells odd when it first turns on, or one room is always warmer than the rest. We start by finding the cause rather than guessing. Then we tell you whether a repair makes sense or whether the equipment is near the end of its useful life.
Our services in Los Altos Hills include:
- AC repair and AC installation
- Heating repair and furnace repair
- Furnace installation
- Heat pump installation
- Ductless mini-split installation for additions, converted garages, or rooms the main system doesn't reach well
- HVAC maintenance visits for heating and cooling equipment
- Duct cleaning
- Indoor air quality improvements such as better filtration
How the Local Climate Affects Your System
The Santa Clara Valley has a Mediterranean climate. Summers are dry, and winters are mild and damp. Inland and southern parts of the valley run noticeably hotter in summer than areas near the Bay, so conditions vary across the South Bay. A system that works fine in one town can be undersized or oversized in another.
Because winters are mild, many furnaces here run in short bursts rather than for long stretches. That can hide small problems until a cold snap. Dry summers mean dust and pollen build up in filters and ducts. During hotter stretches, an air conditioner that has gone a few seasons without service often struggles. A check before each season helps catch worn parts, low airflow and dirty coils before they turn into a breakdown.
Mild winters and warm, dry summers are also the conditions where heat pumps tend to make sense. One heat pump covers both heating and cooling, which is why many homeowners ask us about them.
Thinking About a Heat Pump? What the Rules Actually Say
There is a lot of confusion about Bay Area appliance rules, so here is the short version. The Bay Area Air District's rules do not require you to replace working equipment. They apply only when an existing furnace or water heater fails or is replaced.
Under the Air District's furnace rule, 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. If your furnace is aging, it can be worth planning ahead instead of deciding during a breakdown.
Water heaters follow a separate rule. The zero-NOx date for small water heaters 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 Energy Efficient Home Improvement Credit covered qualifying heat pumps placed in service before December 31, 2025. 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 and availability change by funding cycle, so we confirm the current offer before including it in a quote.
Maintenance, Ductwork and Indoor Air
Routine maintenance is the most practical way to avoid surprise repairs. On a maintenance visit we check airflow, electrical connections, filters, and the condition of key components. We point out anything that is wearing out so you can plan for it.
Ductwork matters as much as the equipment. Leaky, dirty or poorly balanced ducts can make a good system feel weak. If certain rooms never get comfortable, or dust returns quickly after cleaning, we can inspect your ducts and recommend cleaning or other fixes. For indoor air quality, we can talk through filtration options that fit your existing system.
