Full HVAC Installation for Palo Alto’s Eichlers, Craftsmans, and All-Electric Homes
Palo Alto’s housing stock splits into two very different installation jobs: flat-roof Eichlers built on a concrete slab with no attic or crawlspace, and Craftsman-era homes in Professorville and College Terrace with electrical panels still sized for a much smaller house. Air & Plumbing Systems has installed both types across Palo Alto — and because CPAU, not PG&E, is the utility here, the rebate paperwork and interconnection process are different too.
What a Palo Alto Install Actually Involves
- Eichler slab retrofits: no ducts to reuse, so a heat pump usually means either a room-by-room mini-split layout or a compact ducted air handler built into a closet — we’ve done both across Palo Alto’s Eichler tracts.
- Craftsman panel upgrades: homes built before 1930 often carry a 60- or 100-amp electrical panel, and running a heat pump alongside a heat pump water heater can require bumping that to 200 amps first.
We’re licensed under CSLB #901246, based nearby in Campbell, and 25-plus years into this trade — with a good chunk of recent projects specifically inside Palo Alto’s electrification push. Every quote follows an on-site look at the layout, existing ductwork (or lack of it), and panel capacity.
Three Realistic Paths for a Palo Alto HVAC Replacement
Which path fits best usually comes down to what’s already in the walls. Here’s how the three most common options play out for Palo Alto homes:
- All-electric heat pump with the CPAU rebate stack
Electrify My Home currently offers up to $2,500 toward a qualifying heat pump ($5,000 if you qualify by income), plus a separate $2,500 for removing the gas meter entirely — stacked, that’s a meaningful dent in the cost. We verify the live figures against CPAU’s program page before finalizing any quote, since amounts change. - Eichler slab-to-ducted conversion
Homes with radiant slab heat and no ductwork need either mini-splits room by room or a central ducted heat pump routed through a dropped-ceiling chase — the cost gap between the two depends mostly on how many zones you need. - Craftsman-era retrofit with a panel upgrade
Bumping a 60- or 100-amp panel to 200 amps adds an electrical permit and typically a day of work — a step most newer-home installs skip entirely, but one CPAU often requires before approving certain rebate tiers.
Figuring Out Which Path Fits Your Home in Palo Alto, CA
Tell us the age of your house and whether you already have ductwork, and we can usually narrow it to one or two realistic options before we even schedule the on-site visit.
Where Palo Alto HVAC Installs Get Complicated
- Permit timing: Palo Alto’s building department reviews closer than most neighboring cities, and we build that review time into the schedule rather than promising a date we can’t hit.
- No attic, no crawlspace: many Eichler floor plans have neither, so equipment often ends up in a closet air handler or fully outdoors — something a generic quote from outside the area tends to miss.
- CPAU paperwork, not PG&E’s: rebate applications and utility-side electrical sign-off go through City of Palo Alto Utilities’ own process — filing with the wrong utility’s forms is a common reason applications bounce back.
The Repair Calls We Get Most in Palo Alto
- Radiant slab heat gone cold in an Eichler: usually a failed boiler rather than a cracked slab tube — diagnosis starts with the boiler.
- A heat pump losing efficiency during fog season: coastal marine layer moisture affects outdoor unit performance differently than inland heat does, so we check refrigerant charge before assuming it’s just the weather.
- Duct leaks under a retrofitted forced-air system: homes converted from radiant to forced air often route ducts through a converted attic or exposed crawlspace, which is where leaks tend to show up first.
- Thermostat conflicts after a partial electrification: when only the AC side was swapped for a heat pump but the furnace wasn’t, the thermostat sometimes can’t manage both systems correctly.
If your system is a heat pump installed in the last two or three years as part of Palo Alto’s electrification push, tell us that up front — troubleshooting it is a different process than troubleshooting a gas furnace, and it changes which technician and parts we send.
Keeping a Palo Alto System Running Between Visits
- Filters every 60–90 days, more often during wildfire smoke season — Palo Alto’s street canopy of heritage oaks also means outdoor coils collect debris faster than in a stripped-down new development.
- Warranty coverage tied to upkeep: a heat pump installed under a CPAU rebate typically carries a 10–12 year compressor warranty, but that coverage is usually contingent on an annual professional tune-up.
- Past 15 years, whether it’s a gas furnace or an original Eichler radiant boiler, a repair-first approach usually stops saving money.

FAQs
Three things above all: the system type, your home’s size, and its age. Palo Alto has everything from century-old Craftsman homes with no ducts to modern rebuilds — and older properties often need electrical upgrades or custom duct routing that we spot at the free assessment, not mid-project. You receive an itemized quote with no hidden fees before anything is scheduled. Call (408) 733-2000 to book your assessment.
Typically under a week: assessment within a day or two, then installation once you approve the quote. The hands-on work is quick — 4–8 hours for a central AC replacement, 3–6 hours per zone for a mini split, 2–3 days when new air conditioning ductwork is involved. Permits are processed in parallel so paperwork doesn’t slow the schedule.
Yes — it’s worth serious consideration, since Palo Alto’s own electrification push through CPAU makes heat pumps the more heavily subsidized local choice. A ductless mini-split heat pump runs 20–27 SEER2 and skips the 20–30% energy loss that duct leakage causes in older homes; a ducted heat pump typically lands at 15–18 SEER2, comfortably above California’s actual Title 24 minimum of 14.3 SEER2 for new AC installations (California falls in the DOE’s Southwest efficiency region, which moved to that number in 2023 — not the 15.2 figure sometimes quoted). CPAU’s Electrify My Home program currently offers up to $2,500 toward a qualifying heat pump ($5,000 income-qualified), plus a separate $2,500 for removing the gas meter — we confirm the live figures against CPAU’s program page before finalizing a quote, since rebate amounts change.
Usually yes. Palo Alto sits inside our core coverage area, and for calls placed before mid-morning, a same-day slot is typically still open. Trucks stock the parts behind most repair calls — capacitors, contactors, igniters, thermostats — so a large share of repairs finish in one visit rather than requiring a return trip for parts.
Those are two different questions. Past the 15-year mark, efficiency drops and parts for older refrigerant lines get harder to find — a cracked heat exchanger in an aging furnace is also more likely, and it’s the one repair we won’t patch over given the carbon monoxide risk. As a rule of thumb: if a repair estimate comes in above roughly half of what a new system would cost, replacement is usually the better use of that money, especially since a heat pump replacement can currently qualify for CPAU’s electrification rebates and a furnace-only repair can’t.
Book an AC tune-up in spring and a heating check in fall, and change the air filter every 1–3 months. Palo Alto’s leafy streets mean outdoor condensers collect oak leaves and pollen steadily — a quick monthly check of the unit keeps airflow clear. During wildfire smoke events, upgrade to a higher-MERV filter and replace it more often; it protects both your lungs and the blower motor.
