Heat Pump Installation & Service in San Jose

San Jose is a real cooling climate. Summers run hot, with stretches over 100, so unlike the coastal cities, cooling load drives the equipment choice on almost every project. Heating is mild, which means a standard high-efficiency heat pump covers both jobs without any cold-climate hardware. We size to the actual San Jose summer load, not to a Bay Area average.

The housing stock is the widest we work in. Mid-century Eichlers run through Willow Glen, Cambrian, and Fairglen, and they were built with radiant-slab heat and no ductwork at all. The copper-in-concrete radiant systems mostly failed years ago and are not economical to repair because there is no access. For those homes the answer is almost always a ductless mini-split, which keeps the open-ceiling architecture intact and tucks the condenser into a side yard. We have done Eichler retrofits before and ductless is the standard solution.

The 1960s through 80s ranches across Almaden and West San Jose, and the post-2000 infill in North San Jose, are a different conversation. Those have intact ductwork, so the question is increasingly heat pump replacement at end-of-life rather than another gas furnace. We run the load calculation, check the panel, and put the numbers on the estimate before any sale conversation.

What we run into in San Jose

Ductless mini-split retrofits for Eichlers. Eichler radiant slabs are dead and uneconomic to repair. We install ductless mini-splits with wall-mounted heads that respect the open-ceiling design and a condenser placed out of sightlines. This is our standard Willow Glen and Cambrian solution, and we plan head zoning during the walkthrough.

Ducted heat pump replacement on 90s-and-later stock. Homes with intact ductwork get the conversion conversation as the gas furnace ages out. We pressure-test the existing line set, confirm whether it can be flushed and reused, and size for the San Jose summer cooling load. Daikin and Mitsubishi variable-speed are our usual recommendations.

AC-driven sizing and system selection. Because San Jose summers actually run hot, the cooling number leads. We avoid the common mistake of oversizing, which short-cycles and never dehumidifies properly. A correctly sized variable-speed heat pump modulates through the summer instead of slamming on and off.

PG&E and manufacturer rebate stacking. San Jose is PG&E territory, so we stack PG&E programs with manufacturer instant rebates where they apply. We confirm what is actually paying when we write the estimate and handle the paperwork as part of the install.

Heat Pump Installation & Service in San Jose: common questions

You are based in San Ramon. Do you regularly cover San Jose?

We do. San Jose is about 40 to 45 minutes south of our San Ramon shop, and it is one of our higher-volume areas for heat pump work because of the Eichler and ranch stock. We book San Jose jobs as scheduled appointments with a real arrival window rather than same-day promises.

My Eichler has the original radiant heat. Can you fix it instead of replacing it?

Almost never economically. The radiant tubing is copper cast into the concrete slab, so a leak means there is no access to repair it without breaking up the floor. The right answer is usually a ductless mini-split that heats and cools without touching the slab or the open ceilings.

What does a heat pump install include here?

A full Manual J load calculation, equipment sizing, line set inspection, electrical capacity check, permit and inspection coordination, removal of the old equipment, commissioning, and the rebate paperwork. New installs carry a 10-year parts and 10-year labor warranty. The $75 diagnostic credits toward any repair over $200.
