Heat pumps in San Francisco & Marin
A heat pump heats and cools your home with one system, and the mild climate in San Francisco and Marin suits one well.
How a heat pump works
A heat pump moves heat instead of making it. In winter it pulls heat from the outdoor air and brings it inside. In summer it runs in reverse and carries heat out of the house. One outdoor unit does the work of both a furnace and an air conditioner, and it runs on electricity.
Why they suit San Francisco and Marin
Winters here are mild and hard freezes are rare, which is when a heat pump works best. Summers are getting warmer, and a heat pump gives you cooling on heat-wave days without adding a second system. Plenty of homes that never had air conditioning get it for the first time this way.
Is your home ready for one?
- Ductwork. A ducted heat pump can use your existing ducts if they are sealed and sized for the airflow it needs. We check them first.
- Electrical panel. Older panels sometimes need a dedicated circuit or an upgrade. We look before we quote, so there are no surprises.
- Outdoor unit placement. We plan a spot that stays quiet for you and your neighbors, with room for airflow and service.
- Backup heat. Some systems use electric backup heat on the coldest mornings. We set it up to run only when it is actually needed.
Replacing a furnace or AC with a heat pump
When a furnace or air conditioner is near the end of its life, that is the natural time to look at a heat pump. We compare repairing what you have, replacing it like for like, and switching to a heat pump, with honest numbers for each, so you can decide.
Utility and state rebates for heat pumps open and close often, so we check what is available for your home when we quote.
More ways we can help
Good to know
Will a heat pump keep my home warm in winter?
Yes. Modern heat pumps keep heating well at temperatures far colder than San Francisco and Marin usually see. On a rare frosty morning, backup heat can help the system catch up.
Can I keep my gas furnace as a backup?
Yes. A dual-fuel setup pairs a heat pump with a gas furnace and switches to the furnace on the coldest days. It is a good option if your furnace still has years left in it.
Are heat pumps noisy?
Modern outdoor units are quiet, often quieter than an older AC condenser. Placement still matters, so we plan where it goes before anything is installed.
Should I repair my old system or switch now?
If your current system runs well, there is no rush. If it needs a major repair or is near the end of its life, we will price both options side by side.
