Heat Pump & Mini-Split
Working in Sunnyvale
- Housing stock
- Sunnyvale holds around 1,100 Eichlers and is where the very first ones were built, so radiant-slab, no-attic construction is common here. The rest is dense post-war tract housing where original ductwork is often undersized for a modern high-efficiency system.
- Permits
- HVAC permits run through Sunnyvale One-Stop Permit Center, with Title-24 documentation and HERS verification where required — we handle the paperwork.
- Electricity & clean energy
- Silicon Valley Clean Energy
- Heat-pump rebates
- Sunnyvale stacks Silicon Valley Clean Energy's eHub-reserved heat-pump HVAC and water-heater rebates with a City of Sunnyvale heat-pump HVAC rebate where the job qualifies. Reserve SVCE before the crew arrives. TECH Clean California is waitlisted and the federal 25C credit expired after 2025; current SVCE and city amounts go in the written estimate.
The first Eichler houses went up in Sunnyvale, and about 1,100 of them are still here — radiant slab, post-and-beam ceilings, no attic, nowhere a duct belongs. When that slab loop fails, opening the floor to hunt the leak is usually the expensive way to postpone the real answer: a ductless or slim-duct heat pump that heats and cools without touching the floor. The rest of the city is a different problem entirely. PULSE HVAC serves both on scheduled routes from Carmichael (about 2 hours 30 minutes), booking 1–3 business days out, with free in-person estimates, a firm two-hour window, and zero trip fees.
The original Eichler problem
Heritage District bungalows and the Eichler tracts are not interchangeable. The Eichlers have no attic and a roof assembly you do not casually penetrate; equipment selection is driven by what the structure allows — wall heads, ceiling cassettes, compact outdoor units, line sets run with the beam grid. That is specialist work, and it is why we will not quote these houses from a photo of the old boiler.
Tract ducts that never grew
Cherry Chase, Birdland, Murphy Park, Ortega Park, and Lakewood are dense post-war tract. Original ductwork is often still in the crawl or attic, and it is often undersized for a modern high-efficiency heat pump. Putting a larger condenser on those runs just moves the complaint from "the unit is old" to "the far bedrooms never cool." We measure leakage and return sizing before we talk tonnage. A smaller, quieter heat pump on corrected ducts is a common outcome.
Does Sunnyvale's city heat-pump rebate stack with Silicon Valley Clean Energy?
Yes, for qualifying heat-pump HVAC jobs — the City of Sunnyvale runs its own municipal rebate on top of SVCE, which is unusual in this county.
Both have to be reserved before installation, and SVCE's eHub reservation is the one with a completion window. We sequence the paperwork so neither incentive is left on the table, and we put current amounts in the written estimate rather than quoting numbers that rot.
A city rebate that stacks with SVCE
Sunnyvale sits in Silicon Valley Clean Energy territory: heat-pump HVAC and water-heater rebates with income-qualified tiers, reserved through the eHub before anyone installs. On top of that, the City of Sunnyvale runs a municipal heat-pump HVAC rebate that can stack with SVCE. BayREN ended in 2024. TECH Clean California sits on a waitlist. 25C expired after 2025. Permits run through the Sunnyvale One-Stop Permit Center; we pull them, file Title-24, and schedule HERS verification where required. PULSE HVAC is CSLB C-20 licensed statewide.
Carmichael to Sunnyvale is about 2 hours 30 minutes, which is why this is batched, scheduled work. System fully down? Call (916) 850-2221 first and we will tell you straight whether we can fit you in.
HVAC FAQ — Sunnyvale
Sunnyvale is on the South Bay rotation out of Carmichael, about 2 hours 30 minutes away, so the honest lead time is 1–3 business days with a firm two-hour arrival window. We do not run same-day emergency trucks across that drive. If the house is fully without heat or cooling, call (916) 850-2221 first — we will say whether the next batched route can take you or whether a local partner gets there sooner.
Yes. PULSE HVAC is a California CSLB C-20 contractor, licensed for heating, ventilating, and air-conditioning statewide, Sunnyvale included. Every mechanical permit is pulled at the Sunnyvale One-Stop Permit Center. Title-24 compliance paperwork and HERS testing are filed with the job when the scope requires them — including on Eichler retrofits, where the city expects the design, not just the equipment, to be in the package.
Two live stacks, not one. Silicon Valley Clean Energy pays heat-pump HVAC and water-heater rebates with income-qualified tiers, reserved through the SVCE eHub before installation. The City of Sunnyvale also runs its own municipal heat-pump HVAC rebate that can stack with SVCE for qualifying jobs. Do not budget for BayREN (ended 2024), TECH Clean California (waitlisted statewide), or 25C (expired after 2025). Current amounts — no guesses — go in the written estimate.
Sunnyvale is where the first Eichlers were built, and a failed radiant slab is exactly the retrofit we specialize in: ductless or slim-duct heat pumps, not a boiler-loop repair. The rest of the city is dense post-war tract where the ducts, not the box, decide the job. We charge zero trip fees from Carmichael, every estimate is free and in person, and we will tell you if a faster local option is the better call.
Eichler streets get ductless and slim-duct heat-pump designs that never touch the slab. Cherry Chase, Birdland, Murphy Park, Ortega Park, and Lakewood more often get a ducted heat-pump change-out once we have measured the original runs. We also handle central AC, indoor air quality, and thermostat work. Same-day emergency repair is not a Sunnyvale offering — the Carmichael drive does not support it.
An Eichler and a Cherry Chase ranch are different quotes, which is why we will not price Sunnyvale off a phone call. Estimates are free, in person, with no trip charge; the number you get is firm and itemized. Financing is available on larger replacements. We identify the live City of Sunnyvale rebate and the SVCE eHub rebate so you see after-incentive cost, not sticker.
