The short answer
FrostPoint AC Repair installs heat pumps in Fremont homes, sized with a room-by-room load calculation and fitted to your ducts, panel, and yard. You don't have to replace a working furnace, but Air District rules for gas furnaces made from 2029 make a heat pump the likely choice when you do replace one.
A heat pump heats and cools your home with one system by moving heat instead of burning gas to make it. For Fremont homeowners replacing an aging furnace, an old central air conditioner, or both, it is often the most practical next step. FrostPoint AC Repair plans and installs heat pumps in Fremont homes across ZIP codes 94536, 94538, 94539, and 94555. Our crews drive up from our base in San Jose, about 16 miles south.
Why Fremont homeowners are planning around heat pumps
Fremont is in Alameda County, which falls under the Bay Area Air District. Under the district's Rule 9-4, natural gas furnaces manufactured from 2029 on must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when they replace a furnace after that date.
The rule does not force anyone to tear out working equipment. The district's appliance rules apply only when an existing furnace or water heater fails or is replaced. If your furnace runs well, you can keep using it. What changes is the planning. If your system is getting old, choosing a heat pump before it fails gives you time to compare options. Otherwise you may end up making a rushed decision during a cold, damp week.
Water heaters fall under a separate rule, Rule 9-6, which set a zero-NOx date of 2027 for small water heaters. The Air District Board is considering amendments in November 2026 that could delay that date. If you're thinking about converting your water heater at the same time, we'll check the current rule with you before anything is planned.
Sizing a heat pump for your Fremont home
A heat pump that is too large cycles on and off, wastes energy, and leaves rooms feeling clammy. One that is too small runs nonstop on the hottest afternoons. We size each system with a room-by-room load calculation. It looks at square footage, insulation, window area and direction, ceiling height, and how much outside air leaks in.
Weather varies across our service area. The Santa Clara Valley has a Mediterranean climate with dry summers and mild, damp winters, and inland spots run noticeably hotter in summer than places near the Bay. Because of that range, we size for your actual house rather than a regional rule of thumb. Before we recommend equipment, we also check:
- Existing ductwork: size, condition, leaks, and whether it can carry the airflow a heat pump needs
- Electrical panel capacity and whether a new dedicated circuit is required
- Outdoor unit location: clearance for airflow, drainage, and distance from bedrooms and neighbors' windows
- Ducted versus ductless mini-split options for homes without ducts, room additions, or converted garages
- Thermostat compatibility, so the system's heating and defrost controls work as designed
What installation looks like
Once the plan is settled, the work follows a predictable sequence:
- A walkthrough and a written scope describing the equipment, location, and any electrical or duct work
- Pulling any permits the city requires
- Removing old equipment and properly recovering refrigerant
- Setting the outdoor unit on a pad or wall brackets
- Installing the indoor air handler or coil, refrigerant line set, condensate drain, and wiring
- Sealing or adjusting ducts where the inspection showed problems
- Startup, refrigerant charge check, and airflow testing
- A walkthrough of thermostat settings and normal operation, including winter defrost cycles
Rebates and tax credits: what applies now
The federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date, so don't count on it when budgeting a new system.
Local programs may still help. Bay Area homeowners can check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change with each funding cycle, so we confirm the current offer before including it in any quote.
