Should Mendota switch to a heat pump?

In Mendota, a heat pump pays for itself within a reasonable window. 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. Mendota's residents would see roughly $231 a year back in running costs, putting the payback around 4.3 years. The window here is reasonable, and it's specific to what Mendota actually pays for power and gas.

How cold Mendota actually gets

Degree days tell the story here: Mendota racks up 2176 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 2183 cooling degree days on the cooling side. 30°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 28°F on file. Worked through the model, that's a seasonal COP of 3.09 on the standard unit fit for this climate. Mendota's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. Climate figures trace to the nearest NOAA station, MADERA MUNICIPAL AIRPORT, 21.8 miles from Mendota.

The month-to-month numbers for Mendota

A 2000-square-foot house here would pull roughly 1,783 heating kilowatt-hours annually on top of cooling, totalling about $1,196 a year on electricity. That compares with roughly 23 Mcf a year of gas at Mendota's 22.01 per-Mcf rate — about $1,428 a year — against a local electricity rate of 32.83¢/kWh. Buy it outright, not incrementally, and payback stretches to 47.6 years; over 15 years the net position sits $2,467 ahead.

The other scenario: no gas furnace to begin with

Gas isn't universal in Mendota — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,541 a year, which recovers the extra $5,500 spent going electric in roughly 3.6 years.

Mendota against the rest of the country

Ranked against the other 3206 cities covered, Mendota comes in at 2346 for heating severity — 1 would be the coldest place in the dataset — and 2712 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.
