What we see in San Jose homes
Climate. San Jose summers run 85–95°F with stretches over 100°F. Cooling load drives equipment selection for almost every project; heating is mild (design 35–38°F). CEC climate zone 4.
Housing stock. Wide spread: mid-century Eichlers in Willow Glen and Cambrian, 1960s–80s ranches and split-levels across Almaden and West San Jose, post-2000 infill in North San Jose. Eichlers need ductless or low-profile ducted solutions, original radiant slabs are usually dead.
Typical systems. Heat pump installations (both ducted and ductless mini-split for Eichlers), AC repair, full system replacement on 20+ year systems. Goodman and Carrier dominate the post-2000 stock; older homes have a long-tail of Trane, Lennox, and York.
The Eichler problem
Original mid-century Eichler homes, common across Willow Glen, Cambrian, and Fairglen, were built with radiant-slab heat and zero ductwork. The radiant systems mostly failed years ago and are uneconomic to repair (copper-in-concrete = no access). The right answer for these homes is almost always ductless mini-split: wall-mounted heads avoid the original architecture’s iconic open ceilings, condensers tuck into side yards out of view. We’ve done 12+ Eichler retrofits since 2023; mini-split is the standard solution.
Newer stock: heat pump conversion pressure
For 1990s and later San Jose homes with intact ductwork, the conversation is increasingly about heat pump replacement at end-of-life rather than another gas furnace. BAAQMD Rule 9-4 will restrict gas furnace replacement starting 2029, and PG&E’s San Jose customers can stack rebates with manufacturer instant cycles. Daikin Aurora and Mitsubishi Hyper-Heat are our standard recommendations, both maintain full capacity well below San Jose’s 35°F design heating temperature. See our California HVAC rebates 2026 guide for the active stack.
