How much does a new HVAC system cost in San Jose?

A standard furnace replacement in San Jose typically starts around $5,000. Adding central air conditioning ranges from $6,000 to $18,000. A heat pump system starts around $14,000. A complete gas-to-electric heat pump conversion — including furnace removal, new condenser, new air handler, dedicated electrical circuit, and permit — runs approximately $19,500 before rebates.

Three variables drive every one of those numbers: efficiency, noise, and features.

What pushes the price up:

• Higher efficiency ratings (SEER2, HSPF2)
• Variable-speed blowers and inverter compressors
• Passive filtration and air quality upgrades
• Larger equipment size (tonnage)
• Quieter operation
• Zoning capability

Why the installer matters more than the brand

This is the part the industry doesn’t advertise.

Every year — and this is not an exaggeration — Bellows tears out and completely replaces more than ten systems that are only a few years old, because they were installed so poorly they could not be salvaged. Not repaired. Replaced.

A properly installed HVAC system should deliver 15 or more years of reliable service. A badly installed one can fail in two or three.

So when a low bid comes in a few thousand dollars under everyone else, be clear-eyed about what that savings buys you. Paying $2,000 less today and replacing the entire system in three years isn’t a discount. It’s a down payment on doing the job twice.

What to look for in a San Jose HVAC contractor

Every company’s website says they’re the best. Look for the things that are hard to fake.

Longevity. Bellows has served San Jose and the Bay Area for over 40 years. The turn-and-burn shops that appear each spring aren’t around to honor a warranty in year seven.

Reviews at volume. Not five reviews. Hundreds, across years, across platforms.

Family ownership. We’re not a private-equity roll-up. Our name is on the truck, and it stays there.

Community recognition. Bellows was voted Best of Santa Cruz County by Good Times Magazine this year — decided by the people we actually work for.

Permits and inspections. If a contractor suggests skipping the permit, walk. That’s your answer.

Brand range. A contractor who only sells one brand isn’t giving you a solution. They’re giving you a sales pitch.

Santa Clara County heat pump rebates you should be claiming

Heat pumps are dominating our 2026 install calendar, and it’s not close. Between California’s push toward all-electric homes and the incentives currently available, this is the best year in memory to make the switch.

Bellows designs systems that qualify for rebates through:

• San José Clean Energy (SJCE)
• Silicon Valley Clean Energy (SVCE)
• Peninsula Clean Energy (PCE)

Here‘s where homeowners lose money: rebate eligibility is tied to specific equipment models, efficiency thresholds, and installation standards. Pick the wrong unit by a single spec and you can forfeit a substantial incentive.

We design around eligibility from day one, so the system you want is also the system that qualifies.

These rebates are consumer-applied — the homeowner submits the paperwork, and the money goes directly to the homeowner. We’ll identify the right program and make sure you have everything you need to file.

One brand doesn’t fit every San Jose home

San Jose housing stock is anything but standardized. A 1950s Willow Glen bungalow with no ductwork needs a fundamentally different approach than a two-story Evergreen home with an attic air handler.

Bellows designs and installs Mitsubishi, Lennox, and Quilt heat pump systems, plus a full portfolio of conventional furnace and AC equipment.

Because we aren’t locked into a single product line, we custom craft a solution around your home — instead of forcing your home to accommodate the one system we happen to stock.

Real San Jose Heat Pump Install: Trovare Court

Here’s what this looks like in practice.

The problem: An aging gas furnace and no air conditioning at all — a very common San Jose setup, and a miserable one in August.

The solution: We removed the gas furnace entirely and installed a high-efficiency Lennox heat pump system rated at 19+ SEER2, placing it among the most efficient and quietest units on the market.

Scope of work:

• Complete removal of the existing gas furnace
• New outdoor heat pump condenser
• New indoor air handler
• New dedicated electrical circuit run to the heat pump
• Permit pulled, inspection passed

Result: Gas-free heating through winter and precise, even cooling on the hottest summer days — from a single system.

Total project cost: $19,500 before rebates. Rebates on this system are consumer-applied and go directly to the homeowner, bringing the effective net cost meaningfully lower.

That’s a full electrification of the home’s heating, plus air conditioning the home never had, built to a standard designed to last 15+ years.
