Will a heat pump pay off in Port Orchard, WA?
In Port Orchard, the math is close enough that it comes down to how long you plan to stay. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Lower bills claw that back: about $331 saved annually, for a payback of roughly 10.6 years. Whether that's worth it in Port Orchard depends on how many years you expect to own the place.
The climate behind Port Orchard's payback figure
Port Orchard has a real but manageable winter — 4841 heating degree days a year against a 65°F base — and summers rarely ask much of an air conditioner, at 174 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 16°F, against a record low of 12°F. That puts the seasonal coefficient of performance at 3.08 for the recommended cold-climate unit. A cold-climate unit is the right call in Port Orchard — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, BREMERTON NATIONAL AIRPORT, 7.4 miles from Port Orchard.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 3,980 heating kilowatt-hours annually on top of cooling, totalling about $589 a year on electricity. That compares with roughly 50 Mcf a year of gas at Port Orchard's 17.62 per-Mcf rate — about $921 a year — against a local electricity rate of 14.27¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 40.7 years, leaving the 15-year total $1,471 ahead.
The other scenario: no gas furnace to begin with
Not every home in Port Orchard has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $1,192 a year, which recovers the extra $8,000 spent going electric in roughly 6.7 years.
