Heat Pump Payback in Morrisville, NC
Morrisville, NC: the heat pump payback math
Morrisville technically pencils out, but only past the point the equipment would need replacing anyway. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Lower bills claw that back: about $258 saved annually, for a payback of roughly 21.3 years. Morrisville's own numbers say this pencils out only in theory, not in practice.

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 low of 18°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 18°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Morrisville. These numbers come from Raleigh-Durham International, the closest NOAA station, 5 miles out.
The yearly running costs in 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 the current furnace-and-AC running cost near $812 a year, against 14.93¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,632 behind.
How sensitive Morrisville's result is to prices
This result holds unless electricity climbs above 39.9¢/kWh (it is 14.93¢ now) or gas drops below $6.14 per Mcf (now $16.42); past either point, gas becomes the cheaper fuel in Morrisville. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $258 a year saved, a difference under $1,806 pays back within 7 years here, and under $2,580 within 10.
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 13.2-year payback clears the $10,000 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.
