Heat Pump Installation in San Jose, CA
Want lower energy bills and year-round comfort? A heat pump delivers efficient heating and cooling in one system.
Heat Pump in San Jose & the Bay Area
Heat pumps are the fastest-growing home comfort upgrade in the Bay Area — one system that heats in winter, cools in summer, and runs 2–4× more efficiently than a gas furnace. Promax Service Group installs ducted and ductless heat pumps across San Jose, Cupertino, Sunnyvale, and Santa Clara County, from single-room mini splits to whole-home all-electric conversions.
As a Mitsubishi Diamond Contractor, we install cold-climate hyper-heat systems that hold full capacity even on the coldest Bay Area nights. Rebate programs shift constantly — TECH Clean California funding is currently exhausted statewide, and the federal 25C tax credit ended for installations after December 31, 2025 — so we check every rebate and incentive you actually qualify for at your free estimate instead of quoting numbers that may no longer apply.

Signs You Need Heat Pump
These symptoms can point to a repair, a tune-up, or a system that has reached the end of its life, and a technician can tell you which. The longer a problem runs, the more it tends to cost in energy, repairs, and comfort. Call (669) 777-1997 or book online, and we will find the cause and explain your options.
- Your furnace and AC are both aging and due for replacement around the same time
- You want to stop burning gas and go all-electric
- Summer cooling bills or winter gas bills feel out of control
- You're building an ADU or addition and need efficient heating and cooling
- You want one system instead of maintaining separate furnace and AC equipment

Frequently Asked Questions
What rebates are available for heat pumps in San Jose?
TECH Clean California funding is exhausted statewide, and the federal 25C tax credit ended for installations completed after December 31, 2025. HEEHRA (the income-qualified program) still exists, but single-family funding is fully reserved statewide as of February 2026 — we can add you to the waitlist and apply it automatically if funds return. We check every rebate and incentive you currently qualify for at your free estimate, so your quote reflects real numbers, not expired programs.
Do heat pumps work well in Bay Area winters?
Yes — modern inverter heat pumps heat efficiently well below freezing, and San Jose winters rarely drop under 35°F. Mitsubishi hyper-heat models we install maintain 100% heating capacity down to 5°F, far colder than the Bay Area ever gets.
Can a heat pump replace both my furnace and AC?
Exactly — that's the point. One heat pump replaces both systems, uses your existing ducts in most homes, and eliminates gas combustion in the living space. We'll assess your ductwork and electrical panel during the free estimate.
How long does a heat pump last?
A well-installed heat pump typically lasts 15–20 years, similar to a central AC, with the compressor doing double duty year-round. Correct sizing and an accurate refrigerant charge at install time do more for lifespan than any single upgrade afterward.
Will a heat pump raise my electric bill?
Your electric bill will go up and your gas bill will drop — for most San Jose homes on PG&E rates, the net effect is close to a wash or a modest savings, and it's a bigger savings if you also add solar. We'll model the real numbers for your home and usage during the free estimate.
