Ten months of heat, almost no cooling load
In Lacey, a heat pump runs most of the year for one job. Homes here need heat September through June, ten months of the year. Winter nights average 34°F from December through January through February. Summer afternoons average just 75°F, so the cooling side of the system barely gets used.
That split matters when you're sizing and picking equipment. You want a unit that will carry the heating load reliably for most of the year, not one chosen with summer in mind. Any split-system heat pump installed new has to meet the federal minimums, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, but here the heating side is what you'll actually live with day to day.

Washington requires contractors to register with the state.
Registration puts a contractor's business on file with the Department of Labor and Industries. There is no trade exam behind it, so the state is not vouching for how well a contractor sizes or installs a heat pump. It only means the business is on record.
For this job, the check that actually looks at the work is the permit. In most cities and counties, installing a heat pump needs a permit from the local building office, with an inspection once the work is done. That inspection is what stands behind the installation itself, not the registration number.

- Is a heat pump better than a furnace?
- A heat pump does something a furnace cannot. It cools your home in summer as well as heating it, all from one system. A furnace only burns gas or uses resistance heat to make warmth, so you would still need a separate air conditioner alongside it. Homes here need heat from September through June and cooling isn't a factor most years, so the right choice often comes down to your ductwork, your electric rates, and what you already have installed. A contractor can look at your house and tell you which setup makes more sense.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only moves heat out of your house. A heat pump does that same job in summer, then runs in reverse in winter and moves heat into your house instead. Mechanically they use the same kind of compressor and refrigerant cycle. The difference is a reversing valve that lets a heat pump switch direction, which is why it can replace both your furnace and your air conditioner.
- Does a heat pump work in cold weather?
- Yes. A heat pump pulls heat from outside air even when it's cold, because there is still heat in air well below freezing. Winter nights here average 34°F, which a properly sized heat pump handles without trouble. As the temperature drops further, a heat pump's output drops too, so sizing it correctly for your house and your coldest nights matters. A contractor can size the system to your home and tell you whether backup heat makes sense for your setup.
