Morrisville, NC: the heat pump payback math
Morrisville 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. Lower bills claw that back: about $258 saved annually, for a payback of roughly 13.6 years. Whether that's worth it in Morrisville depends on how many years you expect to own the place.
Why Morrisville's climate drives this number
Morrisville has a mild winter by US standards — 2409 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 2068 cooling degree days. 18°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 18°F on file. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Morrisville sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from RALEIGH-DURHAM INTERNATIONAL, the closest NOAA station, 5 miles out.
The month-to-month numbers for Morrisville
A 2000-square-foot house here would pull roughly 1,949 heating kilowatt-hours annually on top of cooling, totalling about $554 a year on electricity. Morrisville's gas rate of 16.42 per Mcf, applied to the 25 Mcf a year the furnace burns, puts its running cost near $812 a year, against 14.93¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 52.3 years; over 15 years the net position sits $368 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Morrisville heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Morrisville's answer improves. About $757 a year comes back this way, enough that the 10.6-year payback clears the $8,000 premium comfortably within the equipment's life.
How Morrisville compares nationally
Ranked against the other 3206 cities covered, Morrisville comes in at 2235 for heating severity — 1 would be the coldest place in the dataset — and 1258 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

Where Morrisville's figure comes from
The methodology guide walks through exactly how Morrisville's 3.13 seasonal COP and the rest of this page's numbers get built. Morrisville's 18°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
