Heat Pump Installation in San Jose

Home › San Jose › Heat Pump Installation

A heat pump replaces a gas furnace and an air conditioner with one electric system that heats in winter and cools in summer. In San Jose, the switch has its own local steps: a city electricity provider with a rebate that must be approved before you install, city permits, and often a look at your electrical panel. This page is about planning that switch in the right order, so you do not install first and discover later that you missed the rebate or need a panel upgrade.

Cool Aid Air Conditioning & Refrigeration is a family-owned HVAC company founded in 1966, based in Santa Clara next to San Jose, and licensed under CA C-20. For all of our services in the city, see the San Jose HVAC and refrigeration hub.

Why heat pumps suit San Jose

San Jose's climate is close to ideal for heat pumps. Summers are hot and dry, so you need real cooling capacity, and winter nights are cool and damp rather than freezing, which is the range where a heat pump heats comfortably and efficiently. Because most homes here get electricity from San José Clean Energy (SJCE), the city's community electricity provider, with PG&E delivering it and still supplying gas, switching to a heat pump moves your heating from PG&E gas to SJCE electricity. For a longer look at the benefits, read 7 benefits of installing a heat pump in San Jose.

The SJCE EcoHome rebate: get approved first

SJCE's EcoHome Rebate offers $1,500 for a heat pump HVAC system that replaces gas-powered equipment, and $2,500 for homes in designated Environmental Justice Communities (San José Clean Energy). Two rules trip people up:

• The application must be approved before installation. A heat pump installed first and applied for afterward does not qualify.
• It is for SJCE customers. If your electricity comes from SJCE, you are likely eligible to apply; if you are unsure, check your PG&E bill.

Ducted heat pump or ductless mini-split?

The right format depends on the house, and San Jose has every kind.

• Ducted heat pump. If you already have a forced-air furnace with reasonable ducts, common in Evergreen, Berryessa and Blossom Valley, a ducted heat pump usually slots into the same duct system, replacing the furnace and AC together.
• Ductless mini-split. Homes without usable ducts, such as older houses heated by wall heaters or floor furnaces, and mid-century homes that were never ducted, often suit ductless heads in the main rooms. Mini-splits also fit garage conversions, additions and backyard units that the main system does not reach.
• A mix. Some homes use a ducted system for most of the house and a mini-split for a room that was always too hot or too cold.

Our heat pump vs mini-split comparison goes through the tradeoffs in more detail, and the Bay Area residential HVAC guide covers how heat pumps fit alongside other systems.

Electrical panel and circuits

Going from gas heat to a heat pump adds an electrical load. Many older San Jose homes, especially those in Willow Glen, Rose Garden and Naglee Park that still have original or lightly updated service, need a close look at panel capacity. Sometimes a dedicated circuit is enough; sometimes the panel needs work. We check this at the estimate, because if circuits or the panel change, the project needs an electrical permit in addition to the mechanical one.

Permits, HERS and the install itself

In San José, replacing a furnace, air conditioner or heat pump in a single-family home or duplex generally requires a mechanical permit, plus electrical if circuits or the panel change. Common mechanical projects can be applied for online through SJPermits.org (City of San José). HERS verification by an independent rater may also be required on the changeout (California Energy Commission). The order we follow:

• Home visit: load calculation, duct and panel check, and ducted vs ductless recommendation.
• You submit the SJCE EcoHome application and receive approval before we install.
• We pull the permits and schedule the work.
• Installation, with refrigerant lines pressure tested and evacuated, ducts sealed, and the gas line to the old furnace capped safely.
• City inspection and HERS verification where required, then you submit your rebate paperwork according to SJCE's current process.

Our technicians are trained on low-GWP refrigerants including R-32 and R-454B, which many new heat pumps use. We install equipment from manufacturers including Daikin, Amana, Goodman, York, Trane and Carrier, and every installation carries our 1-year parts and labor warranty.

If you only need cooling, see our San Jose AC installation and replacement page. If your furnace just needs to last another winter while you plan, start with furnace repair in San Jose.
