HeatPumpPayback

Should Suffolk switch to a heat pump?

Suffolk sits right on the fence — how long you'll own the house decides this one. 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. Suffolk's residents would see roughly $236 a year back in running costs, putting the payback around 14.8 years. Whether that's worth it in Suffolk depends on how many years you expect to own the place.

The climate behind Suffolk's payback figure

Degree days tell the story here: Suffolk racks up 2893 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1613 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 18°F, against a record low of 16.9°F. That puts the seasonal coefficient of performance at 3.13 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Suffolk sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, SUFFOLK MUNICIPAL AIRPORT, 2.1 miles from Suffolk.

The month-to-month numbers for Suffolk

Electricity use for heating alone comes out to about 2,340 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $616 a year. The gas furnace it replaces burns roughly 30 Mcf a year at 16.79 per Mcf here, for a running cost near $852 a year (electricity here runs 16.58¢/kWh). Buy it outright, not incrementally, and payback stretches to 57.1 years; over 15 years the net position sits $46 ahead.

Electric resistance heat in Suffolk, compared

Not every home in Suffolk 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. Switching saves about $945 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 8.5 years.

Where Suffolk ranks in this dataset

Among 3206 cities, Suffolk's winter puts it at rank 1954 for severity, while its size puts it at rank 325 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 Suffolk

About 103,105 people live in Suffolk, Virginia, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

Where Suffolk's figure comes from

The methodology guide walks through exactly how Suffolk's 3.13 seasonal COP and the rest of this page's numbers get built. At a 18°F design temperature, Suffolk sits in cold-climate territory; the guide to that class of unit explains why.
