The short answer
Heat pumps suit Milpitas well because winters are mild and the same unit also cools. A proper installation starts with a load calculation and a check of your ducts and electrical panel; incentives come from BayREN and local energy programs, since the federal 25C credit ended for installs after 2025.
A heat pump moves heat instead of burning fuel to make it. In summer it pulls warmth out of your rooms and releases it outdoors; in winter it reverses and draws heat from the outside air into the house. For a city like Milpitas, where winter lows are cool rather than freezing and summers are warm but rarely extreme near the Bay, that single machine can replace both a gas furnace and a separate air conditioner. EliteAir Heating & Cooling plans and installs ducted and ductless heat pumps for houses and townhomes in ZIP 95035, about eight miles up the road from our San Jose base. Here is how we decide whether a heat pump suits your home, what the conversion actually involves, and what the current rules and incentives do and do not mean for you.
Is your Milpitas home a good candidate?
Most homes with existing forced-air ductwork can switch to a ducted heat pump without rebuilding the system. The outdoor unit takes the place of the old condenser, or goes on a new pad if you never had central air, and an indoor air handler or a coil paired with a variable-speed blower takes over from the furnace.
Three questions decide how smooth the project will be. First, are the ducts sized and sealed well enough to carry the airflow a heat pump needs? Heat pumps deliver air that feels warm rather than hot, so leaky or undersized ducts show up as complaints about lukewarm registers. Second, does the electrical panel have capacity for a new circuit? Third, is there a reasonable spot outside for the unit, with clearance for airflow and drainage during winter defrost cycles?
Ducted, ductless or a mix
There is no single right layout. The choice depends on how the house is built and how you live in it.
- Ducted central heat pump: the cleanest swap for homes that already have a furnace and duct system in reasonable shape.
- Ductless mini-split: one outdoor unit feeding one or more wall, ceiling or floor heads, useful for homes with no ducts or for rooms the ducts barely reach.
- Hybrid approach: a central heat pump for the main living area plus a ductless head in a garage conversion, addition or upstairs office that runs warmer than the rest.
- Dual-fuel setup: a heat pump paired with an existing gas furnace as backup, sometimes chosen when the furnace is still fairly new.
What the rules and incentives say right now
Bay Area Air District Rule 9-4 requires natural gas furnaces manufactured from 2029 to meet a zero-NOx emission standard. That is why many Milpitas owners with older furnaces are looking at heat pumps now. The Air District rules do not require anyone to tear out working equipment; they come into play when a furnace or water heater fails or is replaced.
Water heaters follow a separate rule, 9-6, with a zero-NOx date for small units set for 2027. The Air District Board is considering amendments in November 2026 that could delay that date, so check the current rule before planning a water heater change alongside your heat pump.
On the money side, the federal 25C Energy Efficient Home Improvement Credit applied to qualifying heat pumps placed in service before December 31, 2025, and it is not available for new installations. BayREN and your local clean energy provider may still offer heat pump or electrification incentives. Those programs change with each funding cycle, so we confirm what is available before it goes into any proposal.
Installation, step by step
After the survey and load calculation, we give you a written scope that lists the equipment, any duct changes, electrical work and the location of each unit. On installation day the crew removes the old condenser and, if it is being retired, disconnects and caps the furnace gas line.
The new air handler or coil goes in, refrigerant lines are run or reused after flushing, and the outdoor unit is set on a raised pad so defrost water can drain. The circuit is pressure tested and evacuated before charging. We then configure the thermostat for heat pump operation, including auxiliary heat settings if the air handler has backup strips, and test both modes before leaving. Where a permit is required, we file it and meet the inspector.
Living with a heat pump
Heat pumps run longer, gentler cycles than furnaces, so the house warms evenly instead of in blasts. Setting the thermostat to one comfortable temperature and leaving it there usually works better than deep nighttime setbacks. Keep the outdoor unit clear of leaves and stored items, change filters regularly, and schedule a yearly check of both heating and cooling. We look after heat pumps in Milpitas and nearby Fremont, Santa Clara, Sunnyvale, Mountain View and Campbell.
