The short answer
ExpertFlow is based about 3 miles from Los Altos Hills and serves the 94022 ZIP code for AC, furnace and heat pump repair and installation. We also handle multi-system homes, zoning, ductless mini-splits, maintenance, duct cleaning and indoor air quality.
Los Altos Hills is practically our backyard. The town sits about 3 miles west of our Los Altos base in Santa Clara County, and the 94022 ZIP code is one of the shortest drives on our schedule. ExpertFlow HVAC Repair Service works on the full range of heating and cooling equipment found here, from a single furnace in a ranch house to several zoned systems serving a large hillside property. We handle repairs, new installations, heat pump and ductless conversions, maintenance plans, duct cleaning and indoor air quality upgrades for Los Altos Hills homeowners.
A short drive makes a difference
When a system fails, distance matters. Because Los Altos Hills is only a few minutes from our shop, we can usually fit diagnostic calls into the same day's route and come back quickly if a part needs to be picked up. That proximity also makes follow-up easier: if you want us to check a new install after its first week of real use, it is an easy stop.
For planned work such as a replacement or a maintenance visit, we coordinate around your schedule, gate access and any household routines you would like us to work around.
Homes with more than one system
Many properties in town are spread out, with living space across several levels or wings. It is common to find two or three separate heating and cooling systems, sometimes from different decades and different brands. Each one has its own filter, thermostat and service needs, and it is easy for one to be overlooked until it fails.
We keep notes on every system at a property, including model numbers, filter sizes and past repairs, so each visit starts with context. During maintenance we service all units, not just the one that happened to make noise last week. If systems are fighting each other because thermostats sit too close together or zones overlap, we can rebalance or reconfigure the controls.
Comfort on a hillside lot
Homes on slopes and ridgelines get more sun and wind than houses on the valley floor, and rooms with large windows can swing from cool in the morning to warm by afternoon. The Santa Clara Valley's dry summers and mild, damp winters set the baseline, but exposure on a particular hillside drives how hard your equipment works.
Solutions we use here include zoning dampers that let different parts of the house run on their own schedule, ductless heads for sunrooms and converted spaces, and variable-speed equipment that ramps gently instead of blasting on and off. These options improve comfort and cut down on the short cycling that wears equipment out.
- Zoned ductwork with separate thermostats by floor or wing
- Ductless mini-splits for studios, offices and garages
- Variable-speed heat pumps and air handlers
- Smart thermostats tied to each zone
Planning a move to heat pumps in 94022
A lot of Los Altos Hills homeowners are already thinking about going electric. If your gas furnace is still running fine, there is no requirement to replace it; the Bay Area Air District appliance rules apply only when a furnace or water heater fails or is replaced. For future replacements, Rule 9-4 requires natural gas furnaces manufactured from 2029 to meet a zero-NOx standard, which effectively points toward heat pumps.
Water heaters follow a separate rule, 9-6, which set a 2027 zero-NOx date for small units. The Air District Board is considering amendments in November 2026 that could delay that date, so check the current rule before planning a water heater swap. For incentives, BayREN and your local clean energy provider are the places to look, and we confirm any offer before including it in a quote. The federal 25C credit covered heat pumps placed in service before December 31, 2025 and is not available for new installations.
Air quality and duct care
Larger homes often have long duct runs through attics and crawlspaces, and those runs gather dust over the years. Duct cleaning clears that buildup, and we inspect for leaks, loose connections and damaged insulation while we work. For indoor air quality, we recommend filtration upgrades sized to each blower, which can help during dry, dusty months and on smoky days.
Regular maintenance on every system ties it all together and keeps small issues from turning into a failure when you need heat or cooling most.
