The short answer
PrimeAir installs ducted and ductless heat pumps in San Leandro homes, sized to the house rather than the old furnace. You don't have to replace working equipment, but furnaces made from 2029 must meet a zero-NOx standard, so planning ahead helps. The federal 25C credit has ended; we check BayREN and local provider incentives before quoting.
If you're thinking about replacing a gas furnace, adding air conditioning, or both, a heat pump can handle heating and cooling with one system. PrimeAir HVAC Repair Service installs heat pumps for homes across San Leandro, including ZIP codes 94577, 94578, and 94579. We're based in Fremont, about 11 miles southeast, so getting to your home is straightforward. This page covers how we approach an installation, what affects the right choice for your house, and how current Bay Area rules and incentives fit in.
Choosing the Right Heat Pump for Your San Leandro Home
San Leandro has a wide mix of houses, from older single-story homes to newer construction and townhomes. That variety means there isn't one standard setup. The right system depends on your existing ductwork, how the home is insulated, which rooms get the most sun, and whether you want to heat and cool the whole house or just certain areas.
Many homes that already have a gas furnace and ducts can switch to a ducted heat pump that uses the same duct system, sometimes after repairs or sealing. Homes without ducts, or additions and converted garages that the main system never reached well, are often good candidates for ductless mini-split heads. Some houses use a combination of both.
- Ducted heat pumps: replace a furnace and air conditioner with one outdoor unit and an indoor air handler
- Ductless mini-splits: individual indoor heads for rooms or zones, with no ductwork needed
- Hybrid setups: a heat pump paired with an existing furnace as backup, where that makes sense for the home
What Our Installation Process Looks Like
We start with a visit to look at the house itself. Sizing a heat pump to match your old furnace's output is a common mistake. An oversized system cycles on and off too often and does a poor job with comfort and humidity. An undersized one runs constantly. We calculate heating and cooling needs based on the home's square footage, windows, insulation, and layout.
We also check your electrical panel. Heat pumps run on electricity, and some older San Leandro homes have panels that may need an upgrade or a dedicated circuit before installation. It's better to know that up front than partway through the job.
- Load calculation for heating and cooling based on your actual home
- Ductwork inspection for leaks, damage, and proper sizing
- Electrical panel and circuit review
- Outdoor unit placement that considers noise, airflow, and side-yard clearance
- Thermostat setup and a walkthrough of how to run the system efficiently
Bay Area Air District Rules and Your Timing
Under Bay Area Air District Rule 9-4, natural gas furnaces manufactured from 2029 onward must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when a furnace is replaced after that date. If your furnace is getting older, it's worth thinking about this now rather than making a rushed decision on a cold night.
These rules do not force you to tear out equipment that's still working. They apply only when an existing furnace or water heater fails or is replaced. If your current system runs fine, you can plan a heat pump installation on your own schedule.
Water heaters are on a separate track. 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. If you're also weighing a heat pump water heater, check the current rule before you plan that replacement. We can talk through how the two projects might fit together.
Incentives and Tax Credits
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 for a project starting now.
Local programs may still help. San Leandro homeowners can check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before including it in any quote.
