San Rafael asks for heat nine months of the year
Winter nights average 43°F from December through February, and the heat has to run from October through June. That's nine months of the year your heat pump carries the load, with almost no season off. Summer afternoons average 71°F, mild enough that cooling barely factors in.
A heat pump installed here needs to hold up to steady winter work more than heavy summer work. Most homes in the area still heat with gas, so if you're switching to a heat pump or adding one, it's doing a job the house wasn't built around. Any split-system heat pump made now has to meet a federal minimum of 7.5 HSPF2 for heating and 14.3 SEER2 for cooling, but with nine months of heating demand, how well it performs on cold nights matters more than the minimum on the label.

California requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to this particular job. It means the state has tested the contractor and keeps a record of them, but it does not follow the crew out to your house or sign off on the work once it is done.
That is what the permit is for. A heat pump installation in most cities and counties in Marin needs a permit from the local building office, and an inspection once the work is finished. The license tells you the contractor was tested. The inspection is what checks the actual installation in your home.

- Is a heat pump better than a furnace?
- It depends on what you're weighing. A heat pump moves heat instead of burning gas to make it, so it heats and cools from the same unit and costs less to run in most months. San Rafael winters are mild, with nights averaging 43°F, which is well within what a heat pump handles without help. Most homes here still lean on gas, so switching is worth a look, but a contractor should size it to your house before you decide.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only cools. A heat pump does the same job in summer but can also run in reverse to heat your home in winter. Both use a compressor and refrigerant to move heat rather than create it, the heat pump just has a valve that lets it pull heat from outside air and bring it in instead of only pushing it out.
- Does a heat pump work in cold weather?
- Yes, modern heat pumps keep working well below freezing. San Rafael's winter lows average 43°F, which is mild enough that a heat pump stays efficient all season without needing backup heat. The colder a climate gets, the harder a heat pump has to work, but that isn't a real concern here.
