HeatPumpPayback

Should Yuma switch to a heat pump?

The math in Yuma isn't close — a heat pump wins outright. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. Lower bills claw that back: about $377 saved annually, for a payback of roughly 2.7 years. Nothing about that conclusion is generic — it's built entirely from Yuma's own numbers.

The climate behind Yuma's payback figure

Yuma barely has a winter to speak of — 688 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 4728 cooling degree days. 37°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 36°F on file. Worked through the model, that's a seasonal COP of 3.3 on the standard unit fit for this climate. A standard ducted system is enough here; Yuma's design temperature doesn't justify the cold-climate premium. These numbers come from YUMA MCAS, the closest NOAA station, 10.8 miles out.

What it actually costs to run, year to year

A 2000-square-foot house here would pull roughly 528 heating kilowatt-hours annually on top of cooling, totalling about $709 a year on electricity. The gas furnace it replaces burns roughly 7 Mcf a year at 18.58 per Mcf here, for a running cost near $1,086 a year (electricity here runs 15.55¢/kWh). Buy it outright, not incrementally, and payback stretches to 29.2 years; over 15 years the net position sits $4,655 ahead.

Electric resistance heat in Yuma, compared

Plenty of homes in Yuma heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $515 a year, which recovers the extra $5,500 spent going electric in roughly 10.7 years.

How Yuma compares nationally

Yuma lands at position 2991 out of 3206 cities on heating severity (coldest is 1), and 319 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
