Heat Pump Payback in Aberdeen, WA
Will a heat pump pay off in Aberdeen, WA?
The payback math works in Aberdeen on paper, past the equipment's own working life. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Aberdeen's residents would see roughly $358 a year back in running costs, putting the payback around 15.3 years. That's a technicality, not a recommendation, for anyone actually living in Aberdeen.

How cold Aberdeen actually gets
Degree days tell the story here: Aberdeen racks up 5112 heating degree days each year (base 65°F), and summers rarely ask much of an air conditioner, with 20 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 19.9°F, and the coldest daily reading in the 2024 station record was 1.4°F. That puts the seasonal coefficient of performance at 3.18 for the recommended cold-climate unit. Aberdeen needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,071 kWh a year to keep it warm, plus cooling, for a combined electric bill near $583 a year. That compares with roughly 53 Mcf a year of gas at Aberdeen's $17.62 per-Mcf rate, about $942 a year with the old AC included, against a local electricity rate of 14.27¢/kWh. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $123 behind.
The break-even point in Aberdeen
Gas would only overtake the heat pump in Aberdeen if electricity rose past 23.1¢/kWh from 14.27¢, or gas fell under $10.89 per Mcf from $17.62. A useful quote test for Aberdeen: the heat pump is worth it within a decade if it costs less than $3,580 more than replacing the furnace and AC, and within 7 years if the gap is under $2,506.
If your home heats with electric baseboard instead of gas
Not every home in Aberdeen 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 $1,268 a year, which recovers the extra $10,000 spent going electric in roughly 7.9 years.
How Aberdeen compares nationally
Aberdeen lands at position 595 out of 3206 cities on heating severity (coldest is 1), and 2189 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
Deciding what's next in Aberdeen, WA
Aberdeen, Washington is home to about 17,044 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system, this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Aberdeen, nothing is lost by holding off until the current equipment genuinely fails.
