Nine months of heat, not much need for cooling
St. Helens doesn't ask much of a heat pump in summer. Afternoons average 75°F, mild enough that cooling barely counts as a season here. Heat is the real job, October through June, nine months a year, with winter nights averaging 34°F.
More than half the homes here heat with electricity, so the heat pump is doing the real work, not sitting in reserve for a furnace. If it's a split system built on or after January 2023, federal rules set a floor of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. A new one needs to be sized for those cold nights that run nine months of the year, not just the handful of warm afternoons in between.

Oregon requires HVAC contractors to hold a state license.
The Construction Contractors Board is the state agency that licenses HVAC contractors in Oregon, and that license belongs to the contractor, not to any single job. It means the state has tested this contractor and keeps a record of them. Work under $1,000 falls outside that requirement, but a heat pump installation runs well past that mark, so the contractor doing this job needs to hold that license.
A heat pump installation also needs a permit from the local building office in most cities and counties, along with an inspection once the work is done. That inspection checks the installation itself, separately from whatever the license already says about the contractor.

- Is a heat pump better than a furnace?
- For most homes here, yes, because a heat pump handles the job on its own without a separate furnace or air conditioner. It moves heat instead of burning fuel to make it, which is why it can also cool your home in summer. St. Helens only sees 75°F on summer afternoons, so cooling demand is light, but you still get it built in. The one thing to check is how the heat pump performs on the coldest winter nights, since your lows average 34°F here and some systems need backup heat below a certain point. A contractor can tell you whether the unit they are proposing covers your coldest nights on its own.
- 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 the same thing in summer, but it can also run in reverse and move heat into your home in winter. That's the whole difference. Mechanically they use the same refrigerant cycle and the same kind of outdoor unit, which is why a heat pump can replace both your furnace and your air conditioner in one system.
- Does a heat pump work in cold weather?
- Yes, a heat pump pulls heat from outdoor air even when that air is cold, down to well below freezing. It gets less efficient as the temperature drops, which is why colder homes sometimes pair one with backup heat for the coldest nights. Your winter nights here average 34°F from December through February, which a modern heat pump handles without much trouble. A contractor can size the system and any backup heat to your home so it keeps up on the coldest nights of the year.
