Coldharbour Heating & Air is an HVAC company serving San Jose, CA with repair and installation work sized to the homes actually built here: 1950s ranches, Eichlers with radiant heat, and newer two-story homes bolted onto older neighborhoods. Our techs work on whatever system is already in the house, from a hallway-closet gravity furnace in Willow Glen to a modern heat pump in Evergreen. The work is quoted up front, the repair is guaranteed in writing for 365 days, and you can reach a live person at (669) 800-4179 any hour you need us.
Why San Jose Homes Are Different
San Jose’s post-war housing boom left us with blocks of single-story ranches and Eichler-style homes built around radiant heating and no ductwork at all. That shapes almost every HVAC job here. An Eichler in the Fairglen tract doesn’t need a bigger furnace; it usually needs a creative route for supply air when the family wants central cooling. A 1960s ranch with a low-slope roof and slab foundation often has no attic chase, so a condenser needs to sit on a side yard pad rather than a roof mount – and that changes the permit path and the price.
Climate is the other half of it. San Jose winters are mild enough that a failing furnace gets ignored until the first 40-degree night, and then it’s urgent. Summers now run hot enough that a dead compressor in July turns a house into an oven by 4 p.m. Recent heat waves have pushed a lot of older homes past what their original cooling plan – if they had one – was ever meant to handle. We plan repairs and replacements around both seasons, weighting AC in the summer load and heat in the winter, because this city genuinely uses both.
Styles & brands we work with
Our Main San Jose Services
Most San Jose calls fall into two buckets: a system that stopped working and needs repair now, or an install project that needs a fixed price and a real plan. All three of our San Jose services are detailed on their own pages, with pricing and what to expect.
AC Repair in San Jose
San Jose AC failures follow a pattern: the first real heat wave finds every weak capacitor and every low refrigerant charge in the city. On a 1950s ranch with a slab foundation, refrigerant lines often run through the slab, meaning a leak means either finding a route around it or opening concrete. Our techs see that regularly enough to quote it honestly. Same-day service is available when you need it, and every repair is covered by our 365-day guarantee in writing. See AC Repair in San Jose for full details.
Furnace Repair in San Jose
San Jose winters are brief but sharp, and many older homes still run on original gravity or floor furnaces that have been patched for decades. In Willow Glen, we regularly find 1950s gravity furnaces tucked into hallway closets, and a repair often means matching an obsolete part or converting a section to a modern air handler in a crawl space. No-heat calls in January get the same written quote and same live-answer phone line as a July AC failure. See Furnace Repair in San Jose for what a no-heat visit costs.
AC Installation in San Jose
Installing central air in a home that never had it is a different job than swapping a unit on an existing ducted system, and San Jose has more of the first kind than most cities. Eichlers with radiant floors and no ducts need careful load calculations and creative routing; a mid-century ranch with a slab foundation may need a ductless mini-split instead. We quote a written fixed price before the job starts, and that price holds. See AC Installation in San Jose for installed pricing on new systems.

What pushes a San Jose repair toward the higher end is access: a furnace in a crawl space costs more in labor than one in a garage, and a condenser on a roof in an HOA neighborhood takes longer than one in a side yard. We quote the specific job in front of you, not a generic city average, and the price doesn’t change at the door.

FAQs About HVAC Company in San Jose
Most repair calls get same-day or next-day service, depending on where you are in the city and what the techs have on the board that day. When your furnace is out on a 38-degree January night, we prioritize no-heat calls the same way we prioritize no-cooling calls in a July heat wave.
Some do. Replacing a furnace or condenser in San Jose generally requires a mechanical permit, and work on Eichler roofs or in HOA-governed neighborhoods can add a review step. We handle the permit paperwork for installs, and we’ll tell you exactly what your job requires before any work begins.
You call us. Every repair we do carries a written 365-day guarantee. If the same repair fails within that year, we come back and fix it at no charge. No forms to file, no argument to make – it’s in writing before the tech leaves the first time.

- Deanna Boleyn"New AC and furnace. They gave me a written quote with a couple of options and no pressure. Showed up on the day they promised and the new system is so much quieter."
- Gloria Dunn"New mini split for the addition. Clean install, on time two days running, and the price matched the written quote to the dollar."
