Heat Pump & Mini-Split
Working in San Mateo
- Housing stock
- The Highlands is the largest contiguous Eichler tract ever built — over 650 homes with radiant slab heat, post-and-beam roofs and no attic to hide ductwork in. Elsewhere San Mateo runs 1920s-50s conventional construction, so the right answer changes street to street.
- Permits
- HVAC permits run through San Mateo Building Division, with Title-24 documentation and HERS verification where required — we handle the paperwork.
- Electricity & clean energy
- Peninsula Clean Energy
- Heat-pump rebates
- San Mateo households on Peninsula Clean Energy claim its Home Upgrade Rebates for gas-to-heat-pump HVAC and heat-pump water heaters. We run PCE's Rebate Finder at the estimate rather than quoting aggregator numbers. BayREN's rebates ended in 2024 and the federal 25C credit expired after 2025 — only what actually pays is itemized in writing.
The Highlands is the largest contiguous Eichler tract ever built — more than 650 homes on radiant slabs, post-and-beam roofs, and no attic. That is a specialist problem. Aragon, Baywood, Shoreview, Hayward Park, Beresford, Sugarloaf, and Hillsdale are a different city: 1920s–50s conventional houses with attics, crawl spaces, and ducted furnaces. The first thing we do in San Mateo is tell those two apart. PULSE HVAC runs San Mateo as scheduled work from Carmichael (about 2 hours), booking 1–3 business days out, with a firm two-hour window, free in-person estimates, and no trip fees.
The Highlands is not the rest of San Mateo
When a Highlands radiant loop dies, repairing the boiler is almost never the honest answer. There is no attic to hide a conventional air handler, the roof assembly does not want casual penetrations, and the floor is the heating system. Ceiling cassettes and wall heads, compact outdoor units placed for setbacks, line sets run with the beam grid: that is the job. We will not quote a Highlands house off a photo of a Hillsdale ranch.
What do you put in a Highlands Eichler when the radiant slab dies?
Almost never a boiler-loop repair. A ductless or slim-duct heat pump is the usual answer, because there is no attic and the slab is the floor.
The same equipment then heats in winter at a fraction of the old hydronic cost and covers the mild cooling the Peninsula actually asks for. That swap is most of the Highlands work we take.
Conventional streets: Aragon through Hillsdale
Everywhere else in San Mateo the original ducted furnace is still the starting point. The question is whether that ductwork still earns a new heat pump, not which outdoor unit to bolt on. We measure leakage and return sizing before anyone talks tonnage — fifty years of window upgrades have usually shrunk the load, and repeating the old nameplate is how houses get short-cycling equipment. Shoreview and Hayward Park sit closer to the bay; Sugarloaf climbs; the load is not one number for the city.
Filing with the Building Division
PULSE HVAC is CSLB C-20 licensed. HVAC permits go through the San Mateo Building Division. We pull them, file Title-24, and coordinate HERS verification where the scope requires it — duct tests on conventional change-outs, the appropriate path on ductless Highlands work. Peninsula Clean Energy's Home Upgrade Rebates cover heat-pump HVAC replacing gas heat and heat-pump water heaters, with CARE/FERA adders; we run the PCE Rebate Finder at the estimate. BayREN's appliance rebates ended in 2024, TECH is waitlisted, and 25C expired after 2025.
A fully down system is a call to (916) 850-2221 first. We will say whether the next batched route from Carmichael reaches you in time. Same-afternoon trucks are not a product we sell at this distance.
HVAC FAQ — San Mateo
We do not keep a truck parked in San Mateo. The next open slot is usually 1–3 business days, dispatched from Carmichael on a two-hour batched Peninsula run, with a firm two-hour arrival window — not a same-day promise. A system that is fully down is a phone call first: (916) 850-2221. We will be blunt about whether our next loop fits or a closer crew should take it.
Yes — statewide CSLB C-20, which covers the city of San Mateo. Every mechanical permit we pull here goes through the San Mateo Building Division. Title-24 compliance paperwork and HERS verification are part of the install when the scope requires them, including on Highlands ductless retrofits where there is no duct system left to test in the usual way.
The live stack is Peninsula Clean Energy: Home Upgrade Rebates for heat-pump HVAC taking the place of gas heat, heat-pump water heaters, and CARE/FERA adders. PCE's Rebate Finder is how we confirm what actually stacks for your address. Do not budget around BayREN (appliance rebates ended 2024), TECH Clean California (waitlisted), or federal 25C (expired after 2025) — those are history, and the estimate only carries what still pays.
Because the Highlands is a specialist problem — 650-plus Eichlers on failed or failing radiant slabs — and conventional San Mateo is a different problem on the next street. We came for the heat-pump and ductless work, not to pretend we are a local emergency shop. Estimates are free and in person, trip fees are zero, and trucks leave Carmichael in the morning on batched routes. A faster local option for a no-cool afternoon is something we will tell you, not hide.
In the Highlands the typical job is a ductless or slim-duct heat pump replacing a dead radiant slab. In Aragon, Baywood, Hillsdale and the rest of conventional San Mateo it is ducted heat-pump and AC replacement, duct repair, smart thermostats, and indoor air quality. We do not sell same-day emergency repair as a San Mateo product; the two-hour drive from Carmichael is why we schedule the work instead.
A Highlands cassette layout and a Hillsdale furnace swap are not the same bid. We price after seeing the house — free, in person, no trip charge — and the quote is firm and itemized. Financing is available on larger replacements. PCE Home Upgrade (and CARE/FERA if you qualify) lands on that page so the number you compare is net of the live rebate, not a sticker someone pulled off a website.
