Heat pump installation in Palo Alto replaces a gas furnace and air conditioner with one electric system that heats and cools. City of Palo Alto Utilities offers a $2,500 rebate ($5,000 for income-eligible households) when a heat pump replaces a gas heater, plus add-on rebates for qualifying panel and wiring work. ComfortFlow sizes the system, files the City instant permit and prepares the rebate paperwork.
Why heat pumps fit Palo Alto so well
Palo Alto’s mild winters are close to ideal for heat pumps. Overnight lows rarely stay far below 40°F for long, which is well within the range where modern variable-speed heat pumps run at high efficiency. The City owns its utility, and CPAU actively supports electrification with rebates, an instant permit path, and a contractor directory.
A heat pump moves heat instead of burning fuel. In winter it pulls heat from outdoor air and moves it inside. In summer it reverses and works as an air conditioner. One system, one maintenance plan, and no combustion inside your home.
CPAU heat pump rebates at a glance
Rebate amounts and rules change, so we confirm current numbers with you before you sign. As published on the City of Palo Alto Rebate Hub:
| Rebate | Amount | Key rule |
|---|---|---|
| Heat Pump HVAC (core) | $2,500, or $5,000 for income-eligible residents | Must replace a gas or fossil fuel home heater |
| Electrical panel upgrade (add-on) | $1,000, or $2,000 income-eligible | Paired with a core rebate; new panel 200 amps or less |
| Wiring, circuit splitter or subpanel (add-on) | $500 per circuit or device | Must serve the new heat pump |
Applications are due within 90 days of final inspection. Our complete CPAU rebate guide covers stacking, timing and the paperwork.
Designing a heat pump system that actually stays comfortable
The most common complaint about heat pumps is “the air doesn’t feel as hot as my furnace.” That’s expected: a heat pump delivers steady, gentler warmth for longer cycles. The fix for comfort is good design:
- Right sizing. A load calculation for heating and cooling, not the tonnage of your old AC.
- Duct check. Heat pumps move more air at lower temperatures, so leaky or undersized ducts matter. See ductwork service.
- Variable speed. Inverter-driven compressors ramp up and down instead of switching on and off.
- Smart controls. Thermostats configured for heat pumps, without aggressive setbacks that trigger backup heat.
Ducted, ductless, or both
Homes with decent ductwork usually get a central ducted heat pump. Eichlers with radiant floors, additions, ADUs and homes without ducts often do better with ductless mini-splits. Some homes use both: a central system for the main floor and a mini-split for a hot upstairs room.
The City instant permit
For detached single-family homes, duplexes and ADUs, a C-20 licensed contractor can pull an instant permit for up to three heat pump systems. The equipment must be rated under 65 dBA, can’t sit on the roof, and can’t be placed between the street and the house or in view from the public right of way. The permit calculates a minimum setback from the property line, which the inspector verifies. We collect the load calculation, the equipment specifications and the energy compliance form for you. Details are in our instant permit explainer.
Heat pump types compared
| Type | How it delivers heat | Best for | Notes |
|---|---|---|---|
| Ducted central heat pump | Through existing ducts | Homes with usable ductwork | Replaces furnace and AC together |
| Ductless mini-split | Wall, ceiling or floor heads | Eichlers, ADUs, additions | Room-by-room control |
| Ducted mini-split | Short ducts from a hidden air handler | Small zones, attics, soffits | Quiet, concealed |
| Air-to-water heat pump | Heats water for radiant floors | Eichlers with healthy slab loops | Replaces a gas boiler |
What a heat pump changes day to day
Heat pumps deliver steady, gentle warmth instead of short bursts of very hot air. The system runs longer at lower speed, which keeps temperatures even and noise low. In summer the same system cools the house, so there is one outdoor unit, one maintenance plan and no combustion appliance indoors.

Answers from the ComfortFlow HVAC Palo Alto team about heat pumps in Palo Alto homes.
How much is the Palo Alto heat pump rebate?
As published on the City of Palo Alto Rebate Hub, the Heat Pump HVAC rebate is $2,500, or $5,000 for income-eligible residents, when the heat pump replaces a gas or fossil fuel heater. Add-on rebates are available for qualifying panel and wiring work. We confirm current amounts before you commit. Income-eligible households can receive the higher amount, and add-on rebates can cover qualifying panel and wiring work. You can also receive the rebate at the point of sale by using a CPAU Instant Rebate Partner. ComfortFlow HVAC Palo Alto lays out the expected rebate in your estimate so you can compare the true cost of each option.
Will a heat pump keep my home warm in winter?
Yes. Palo Alto’s winters are mild, and modern variable-speed heat pumps are designed for far colder climates. Proper sizing and a duct check are what make the difference in comfort. Heat pumps deliver warmth differently: steadier air at a lower temperature for longer run times, instead of short blasts of very hot air. Most people find that more comfortable once they are used to it. Thermostats should be set for heat pumps, with modest setbacks, so the system does not rely on backup heat during cold mornings.
Do I need a new electrical panel?
Not always. Many homes can add a heat pump with load management or a circuit splitter. If a panel upgrade is needed, CPAU offers an add-on rebate when it’s paired with a heat pump. Many Palo Alto homes were built with 100-amp service. A heat pump plus an induction range, EV charger and heat pump water heater can exceed that. Load calculations tell us what you actually need, and devices like circuit splitters or smart panels can often avoid a costly service upgrade while still qualifying for CPAU add-on rebates.
Where can the outdoor unit go?
Under the instant permit, not on the roof and not between the street and the house or visible from the public right of way. Side and rear yards that meet the calculated setback are typical. The instant permit calculates the minimum setback from your property line based on the unit’s sound rating, and the inspector verifies it. We pick a location that meets the setback, stays out of view from the street, keeps refrigerant lines short and has room for service. On tight lots, a quieter unit can open up more placement options.
Can I keep my gas furnace as backup?
You can design a dual-fuel system, but it won’t qualify for the CPAU rebate that requires replacing the gas heater. In Palo Alto’s climate, most homeowners don’t need gas backup. Dual-fuel systems use a heat pump most of the time and switch to gas during the coldest hours. They make more sense in colder regions. In Palo Alto, keeping gas usually means keeping a gas bill, a combustion appliance indoors and the furnace maintenance, while losing the main CPAU rebate. ComfortFlow can price both so you can decide.
Does a heat pump work with radiant floors?
Air-to-water heat pumps can feed radiant floor systems, and many Eichler owners pair radiant heat with ductless cooling. See our radiant heating page. Radiant floors work well with heat pumps because they need lower water temperatures than radiators. The key is the condition of the slab loops: if they hold pressure, an air-to-water heat pump can replace a gas boiler. If the loops are failing, ductless heat pumps can take over heating and add air conditioning at the same time.
