Nine months of heat, mild summers, and not much cooling to speak of
Your heat pump in Polk County works most of the year, October through June. Winter nights average 35°F, which is not extreme cold, but the unit still has to run steadily through three full months of that before it ever gets a break. Summer only asks it to cool down to an average afternoon of 77°F, and for just a few months at that.
That split matters when you're choosing a new system. You want one built to hold up under long, steady heating demand, not one sized around a tough summer that Polk County doesn't really have. Any split-system heat pump installed new has to meet 7.5 HSPF2 for heating and 14.3 SEER2 for cooling, the federal minimums as of 2023, so the heating side of that rating is the one doing most of the work here.

Oregon requires HVAC contractors to hold a state license.
The Construction Contractors Board licenses the contractor, not the job. That license stays with the business across every project it takes on, and the board keeps a record of it. Work under $1,000 falls outside the requirement, but a heat pump installation runs well past that line, so the contractor on this job holds a license the state issued and keeps on file.
Once the unit is in, most cities and counties in Oregon require a permit for the installation, along with an inspection when the work is finished. The license is what says who is allowed to do the job. The permit and inspection are handled by the local building office, separate from the state license itself.

- Is a heat pump better than a furnace?
- It depends on what you're paying for heat with. A heat pump moves heat instead of burning fuel to make it, so it uses less energy to deliver the same warmth. Here, more than half of homes already heat with electricity, and a heat pump is usually the more efficient way to do that. A furnace still makes sense in some homes, so it's worth having a contractor look at what you have now before deciding.
- 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 the same job in summer, but it can also run in reverse and move heat into your house in winter. The parts inside are almost the same. The difference is the reversing valve that lets a heat pump switch directions.
- Does a heat pump work in cold weather?
- Yes. A heat pump still pulls heat from outside air even when it's cold, though it has to work harder as the temperature drops. Winter nights here average 35°F, which is well within the range a modern heat pump is built to handle. Heat pumps installed now also have to meet a federal minimum of 7.5 HSPF2, a rating that reflects how well they perform through a full heating season, not just on a mild day.
