What we do
No subcontracted installs, no commission-only "comfort advisors". The technician who diagnoses your system is the one who fixes it.
Capacitors, contactors, refrigerant leaks, frozen coils. When it's time to replace, a Manual J load calculation first, then a right-sized system, not the biggest one on the truck.
Repair and installation visits by arrangement
Gas furnace repair, safety inspection and replacement. Every visit includes a carbon-monoxide reading at the registers and a look at the heat exchanger.
Tune-up 60–90 min · replacement in one day
One outdoor unit that cools in summer and heats in winter. Ducted or ductless mini-split. We file the Silicon Valley Power and TECH Clean California rebate forms for you.
Rebate paperwork included
Leaky, crushed or undersized ducts waste a third of what your system makes. We pressure-test, seal with mastic, and replace runs that can't be saved. Then we HERS-test the result.
Most attics done in 1–2 days
MERV 13 media filters, whole-house fresh-air ventilation and humidity control. These are the fixes that actually help on wildfire-smoke days, not plug-in gadgets.
Fitted during a tune-up
A spring cooling visit and a fall heating visit, filters changed, and a place at the front of the line when the heat wave hits. Three tiers below.
Priority scheduling for members

Maintenance plans
Members get a text the week before each visit, the same technician where we can, and the first open slot on 100-degree days.
Plans are priced per home after the first visit. The number depends on how many systems you have and how old they are. No contracts; cancel by phone any time.
Manufacturer names shown as plain text for a sample site. We repair every brand, including the ones not listed.

A 1920s bungalow with no ducts and a window unit that rattled the sash. One wall head, one outdoor unit, line set hidden in the eave.
Before → after
Twenty-two-year-old condenser with a failed compressor. New two-stage unit matched to the existing coil, new pad, new disconnect, HERS test passed first time.

Cracked heat exchanger found on a fall tune-up. Replaced with a two-stage 96% furnace, new plenum, and the garage closet finally sealed from the house.
Reviews added after verification
"Called at 7:40 on the first 100-degree day. Tech was in our driveway at 9:15 and the AC was running by ten."
"They talked me out of a new furnace. It was a flame sensor. I didn't know HVAC companies did that."
"The heat pump rebate forms were done before I'd even asked. The house is quiet now. The old unit used to shake the fence."
Where we work
Based on Walsh Avenue, we serve Santa Clara and nearby communities. Call to check availability in your area.
Questions we're asked a lot
It depends on the size of the house, the state of the ducts, the electrical panel and which rebates you qualify for, so we don't quote from a form. A technician measures the house, runs the load calculation and gives you a written fixed price with the permit and HERS test included.
Our rule of thumb: if the system is under twelve years old and the repair is a single part, repair it. If it's older and the compressor or heat exchanger has failed, replacing usually makes more sense. We'll show you both numbers on the same visit and let you choose.
Yes. Our January nights rarely drop below the high 30s, and modern inverter heat pumps hold full output well below that. Most of the heat pumps we install replace a gas furnace and an AC at once, and the owners stop noticing the difference within a week.
Every replacement, yes. We pull them with the City of Santa Clara, Sunnyvale or wherever the house is. California also requires a third-party HERS duct test on most changeouts; we schedule it and pass it before we call the job done.
If your system has stopped heating or cooling, call to describe the problem and check availability. If you smell gas, leave the building and contact your gas utility or emergency services from outside.
