Heat Pump Payback in Sandy, OR
Should Sandy switch to a heat pump?
Sandy technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Sandy would pay extra to go electric rather than replace the furnace and AC with the same again. Sandy's residents would see roughly $244 a year back in running costs, putting the payback around 22.5 years. That's a technicality, not a recommendation, for anyone actually living in Sandy.

How cold Sandy actually gets
3827 heating degree days pile up here every year, so Sandy has a real but manageable winter; the cooling side runs to 635 cooling degree days, where summers add a moderate cooling load. 19°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 14°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.16 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Sandy sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Portland-Troutdale Airport, 12.6 miles from Sandy.
Sandy's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 3,067 heating kilowatt-hours annually on top of cooling, totalling about $546 a year on electricity. The gas furnace it replaces burns roughly 40 Mcf a year at $16.71 per Mcf here, for a running cost near $791 a year including the old AC (electricity here runs 15.14¢/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 $1,835 behind.
What would change Sandy's answer
Gas would only overtake the heat pump in Sandy if electricity rose past 23.9¢/kWh from 15.14¢, or gas fell under $10.58 per Mcf from $16.71. A useful quote test for Sandy: the heat pump is worth it within a decade if it costs less than $2,440 more than replacing the furnace and AC, and within 7 years if the gap is under $1,708.
The other scenario: no gas furnace to begin with
Not every home in Sandy has gas service. Swap the comparison to resistance heat instead of gas, and Sandy's answer improves. The saving here runs about $1,045 a year, which recovers the extra $10,000 spent going electric in roughly 9.6 years.
Where Sandy ranks in this dataset
Among 3206 cities, Sandy's winter puts it at rank 1635 for severity, while its size puts it at rank 2654 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Sandy
Sandy, Oregon is home to about 12,990 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 Sandy, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Every constant behind this page, the 3.16 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. At a 19°F design temperature, Sandy sits in cold-climate territory; the guide to that class of unit explains why.
