We cover heating, cooling, water heating, and indoor air quality for single-family homes across 94022 and 94024. As a full-service HVAC company Los Altos residents call for all four, we keep vans stocked, so most repairs finish in one visit. Residential systems only.
With 263 sunny days and peaks near 86°F, cooling matters June through September. We handle same-day AC repair Los Altos homeowners need, plus right-sized installs.
January lows drop to 37°F, so the heating season is real despite dry winters. Schedule furnace service and HVAC repair Los Altos residents book before October.
A 37–86°F range suits standard heat pumps perfectly. SVCE rebates offset the cost, and 1950s–1970s homes convert gas-to-heat pump without major structural work.
Repair, maintenance, and installation for traditional tank units and heat pump water heaters, including replacements in tight garage closets.

Alert
Two local factors drive most system decisions here: mature shade cover and a housing stock that hit its replacement window years ago.
The city gets 263 sunny days, but its urban tree canopy shades properties far more than open suburbs. That usually means smaller cooling equipment is correct here; oversizing remains the most common error.
Most homes here were built between the 1950s and 1970s. Original gas furnaces now run 40–60 years old, and SVCE rebates make heat pump upgrades attractive for this housing cohort.
Between SVCE, statewide programs, and federal tax credits, a Los Altos heat pump project can qualify for several thousand dollars in combined savings.
Available Rebates
California Energy-Smart Homes $4250
Tech Clean up to $1000
Silicon Valley Clean Energy up to $3000
Westlight Energy up $2000
Residential work only, across every part of the city. The building stock ranges widely, and each type brings a different set of mechanical problems and upgrade paths.
The dominant ranch home type: aging gas systems, galvanized supply lines, and some layouts with no central ductwork. Good candidates for ductless heat pumps with SVCE rebates.
All-electric packages built around a heat pump, heat pump water heater, and EV charger, sized ahead of California's 2027 gas equipment rules.
Expanded and renovated properties often need new zones added, full system replacements, and electrical coordination when an EV charger shares the panel.
Larger lots and multi-structure estates need independent climate zones per building. We cover AC repair Los Altos Hills owners need for guest houses and main residences.

Winter in the Bay Area brings wind, heavy rain, and falling branches, and with them come power outages. Sometimes the lights flicker for a few seconds.
November 2, 2026
Bay Area winters are mild, but wet. Weeks of rain, cool nights, and homes that stay closed up for months create ideal conditions for indoor moisture problems. You might notice water droplets on your windows in the morning, a damp feeling in the closet, or a musty smell when the heat kicks on.
October 28, 2026
In the Bay Area, winter doesn’t arrive with snow. It arrives with rain. One week your yard is bone dry, and the next an atmospheric river drops several inches of water in a couple of days. For most homes, that sudden shift is the real test of the season.

Questions & Answers
Yes. Calls placed before early afternoon usually get a same-day slot, and our vans carry common parts for Carrier, Trane, and Lennox systems, so most repairs finish on the first visit rather than waiting on an order.
Silicon Valley Clean Energy offers incentives for qualifying heat pump HVAC and water heater upgrades, and those stack with federal tax credits. Amounts shift with program funding, so we confirm what's active and handle the application when we quote your job.
Three, generally: repair if the heat exchanger is sound, a like-for-like gas furnace replacement, or a gas-to-heat pump conversion that adds cooling as well. The third option carries the rebates, and most ranch homes handle it with modest duct modifications.
It does. Heavy shade cuts solar gain on walls and roofs, which lowers the cooling load. We run a Manual J calculation with the actual shading on your lot, and the result is often a smaller tonnage than square footage alone would suggest.
Yes. Los Altos Hills sits on the same service routes. Estate properties there often run multiple structures on one parcel, and we design independent zones so a guest house or studio doesn't depend on the main residence's system.
A single-zone ductless install sits at the low end, while a whole-home system replacement for a ranch home runs considerably higher. Rebates and financing shift the net figure a lot, so we quote after a load calculation rather than over the phone.
New installations come with a 10-year parts and labor warranty. We handle registration at commissioning, so coverage starts without extra steps on your end, and workmanship is covered alongside the manufacturer's parts terms.
