Nine months of the year, Oakland asks something of a heat pump
Winter nights average 41°F from December through February, and homes here need heat from November through April, six months a year. Summer afternoons average 82°F, with cooling running July through September, three months a year. Between the two, a heat pump here is working nine months out of the year.
Most homes in Oakland still heat with gas, so a new heat pump is often replacing that, not another heat pump. Any split-system unit made since January 2023 has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. That is the floor, worth knowing before you compare quotes.

California requires HVAC contractors to hold a state license.
The license is issued to the contractor, not the job, so it covers whoever is running the business rather than being reissued for each heat pump they install. The state tested that contractor before handing it out and keeps a record of them under the Contractors State License Board.
For this job, that license is what stands behind the work, since California is a state that actually tests and tracks the people it lets do it. Alongside that, most cities and counties here require a permit before a heat pump goes in, and an inspection once it's done, which is a separate check by the local building office on the installation itself rather than on the contractor.

- Is a heat pump better than a furnace?
- It depends on what you're comparing it to, but for most homes here a heat pump does the job well. Winter nights average 41°F, which is well within the range a modern heat pump handles without trouble. The difference is that a heat pump also cools your home in summer, so you get both from one system instead of pairing a furnace with a separate air conditioner. Most homes here still heat with gas, so switching means changing how your home is heated, not just adding equipment.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only moves heat out of your home. A heat pump does that same job in summer, then reverses in winter and moves heat into your home instead. The parts are largely the same, which is why a heat pump can replace both your furnace and your air conditioner. Since homes here need cooling only three months a year but heat for six, that reversing ability is what does most of the work.
- Does a heat pump work in cold weather?
- Yes. A heat pump pulls heat from outside air even when it's cold, and it keeps working as outdoor temperatures drop. Winter nights here average 41°F, which is mild enough that a heat pump sized for this area will heat your home through the whole season without help. Split-system heat pumps sold new today are required to meet a federal minimum of 7.5 HSPF2 for heating, so any new system installed here is built to perform through winter.
