Central ducted heat pumps
A whole-home outdoor unit and indoor air handler using existing or redesigned ducts. Often the most direct furnace-and-AC replacement.

The bottom line
A successful heat pump project starts with the home, not the equipment catalog. The contractor should calculate heating and cooling loads, inspect ducts and electrical capacity, identify a quiet outdoor-unit location, confirm condensate and refrigerant-line routes, and explain permits before recommending a model.
Heat pumps move heat rather than creating it through combustion. One reversible system can heat in winter and cool in summer. In the Bay Area's moderate climate, that can make a heat pump a practical replacement for a furnace, an air conditioner, or both—provided the system is sized and installed for the actual building.
System options
Each configuration solves a different combination of ductwork, zoning, budget, space, and electrification needs.
A whole-home outdoor unit and indoor air handler using existing or redesigned ducts. Often the most direct furnace-and-AC replacement.
One outdoor unit connected to wall, floor, or ceiling indoor units. Useful for older homes, additions, ADUs, and room-by-room zoning.
An electric heat pump paired with a gas furnace. Controls switch heat sources according to temperature, capacity, or operating strategy.
Variable-speed equipment designed to retain useful heating capacity at lower outdoor temperatures—valuable in cooler microclimates and higher elevations.
Heating and cooling components combined in one outdoor cabinet, commonly used where a packaged rooftop or side-yard system already exists.
One outdoor unit serving several independently controlled indoor zones. The design must verify connected capacity, piping limits, and simultaneous loads.

| Question | Heat pump | Furnace + air conditioner |
|---|---|---|
| How it heats | Moves heat using a refrigeration cycle | Furnace burns fuel or uses resistance heat |
| Cooling | Included in the reversible system | Provided by separate AC equipment |
| Energy path | Can support an all-electric home | Often remains dependent on gas |
| Important planning issue | Low-temperature capacity, airflow, panel load | Venting, combustion safety, AC compatibility |
| Best comparison | Total installed scope and seasonal performance | Combined replacement cost and operating plan |
A better process
Review comfort complaints, room use, insulation, windows, air leakage, ducts, electrical service, and equipment access.
Use a room-by-room heating and cooling load calculation instead of replacing equipment by old nameplate size alone.
Confirm model numbers, capacity data, controls, duct and electrical work, permits, startup, disposal, and warranties.
Verify airflow, refrigerant charge, drainage, controls, sound, system operation, and homeowner instructions.
Common homeowner questions
Yes. The Bay Area's generally mild winters are well suited to modern air-source heat pumps. Correct sizing still matters: insulation, windows, air leakage, duct condition, elevation, and inland versus coastal temperatures all affect the equipment selection.
Homes with usable ducts often fit a central ducted heat pump. Older homes, additions, ADUs, and rooms without ducts may fit mini-splits. A dual-fuel system can be considered when an existing furnace remains useful or the homeowner wants a staged electrification plan.
The installed price depends on capacity, efficiency, ductwork, electrical work, equipment access, permits, controls, and the number of indoor zones. A useful estimate separates equipment, labor, electrical, duct, permit, and optional work so competing proposals can be compared fairly.
Not always. A contractor should review the main panel rating, available breaker spaces, existing loads, service capacity, and the selected equipment's minimum circuit requirements. Some inverter-driven heat pumps can fit existing service; other projects need load management or an upgrade.
Often, yes. A reversible heat pump provides heating and cooling from one system. The home assessment should confirm heating capacity, cooling load, airflow, backup-heat strategy, and whether the ducts can support the required air volume.
They can, but the ducts should be inspected for leakage, restrictions, missing returns, poor insulation, and inadequate sizing. Reusing ducts without checking airflow can limit comfort and efficiency even when the outdoor equipment is excellent.
A straightforward central replacement may take one to two working days. Multi-zone systems, major duct changes, panel work, asbestos procedures, difficult access, or permit scheduling can extend the timeline. Ask for a written project-specific schedule.
