The short answer
We plan Palo Alto heat pump installations around your electrical capacity, ducts and other electrification projects, then install a ducted, ductless or combined system sized to the house. We explain the Air District rules and confirm current incentives before including them.
Many Palo Alto homeowners arrive at a heat pump from a broader plan: an induction range last year, solar panels on the roof, perhaps an electric vehicle charger in the garage, and now the furnace is the last major gas appliance left. That context changes how a heat pump project should be planned, because the electrical panel, the ductwork and even the water heater all come into the conversation. ExpertFlow HVAC Repair Service, about four miles away in Los Altos, installs ducted and ductless heat pumps throughout 94301, 94303, 94304 and 94306. Here is how we fit a heat pump into a whole-home electrification path rather than treating it as an isolated swap.
Start with the electrical picture
Every electric appliance you add draws on the same panel. A heat pump, an induction cooktop, an EV charger and a heat pump water heater together can exceed what an older service was designed to carry. Before recommending equipment, we review your panel, the loads already on it and what you plan to add over the next several years.
Sometimes there is ample room. Other times, a smart panel, a circuit-sharing device or a variable-speed heat pump with lower starting current avoids the need for a full service upgrade. When an upgrade is unavoidable, knowing early lets you coordinate it with the utility rather than discovering it halfway through the project.
Matching the system to the house
Palo Alto homes vary widely, and the right heat pump layout follows the building. Houses with attic or crawlspace ducts in good shape can use a ducted heat pump with a new air handler. Slab homes with open-beam ceilings, common in parts of the city, often suit ductless heads in the main living areas and bedrooms. Larger two-story homes may benefit from two smaller systems, one per floor, instead of one large unit fighting the stack effect.
- Ducted heat pump with air handler: homes with sound, well-sealed ducts
- Ductless mini-splits: slab homes, additions and rooms the ducts never served
- Two zoned systems: two-story houses with uneven upstairs comfort
- Hybrid with existing furnace as backup: owners who want a gradual transition
What the rules do and do not require
Under Bay Area Air District Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx emission standard, which in practice points homeowners toward heat pumps when a furnace is replaced after that date. The Air District rules do not require replacing working equipment; they apply when an existing furnace or water heater fails or is replaced.
If your plans include a heat pump water heater, note that the zero-NOx date for small water heaters under Rule 9-6 was set for 2027, and the Air District Board is considering amendments in November 2026 that could delay it. Check the current rule before scheduling that part of the project.
The federal 25C credit applied to heat pumps placed in service before December 31, 2025 and is not available for new installations. BayREN and your local utility or clean energy provider may offer heat pump and electrification incentives, which change by funding cycle, so we confirm the current offer before quoting it.
Sizing for a mild, damp winter
Palo Alto lies near the Bay, where summers are milder than in the hotter southern and inland valley, and winters are cool and damp without hard freezes. That means a heat pump is usually sized by heating and cooling loads that are both moderate. We calculate them room by room and select variable-speed equipment that can run gently for long periods, which keeps temperatures even and the outdoor unit quiet for neighbors on smaller lots.
Install day and what follows
Our crew removes the old equipment, sets the outdoor unit, installs the indoor air handler or heads, runs and pressure tests refrigerant lines, evacuates and charges the system, and completes electrical and drain work. We commission in both heating and cooling, confirm airflow, set the thermostat for heat pump operation and walk you through how it differs from a furnace: steadier, gentler heat and occasional defrost cycles in damp weather. We also install heat pumps in Los Altos Hills, Mountain View, East Palo Alto, Atherton and Portola Valley.
