Should Homewood switch to a heat pump?

In Homewood, the math is close enough that it comes down to how long you plan to stay. 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. Homewood's residents would see roughly $277 a year back in running costs, putting the payback around 12.6 years. Whether that's worth it in Homewood depends on how many years you expect to own the place.

The climate behind Homewood's payback figure

Homewood has a mild winter by US standards — 2068 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 2428 cooling degree days. 17.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 10°F on file. Worked through the model, that's a seasonal COP of 3.11 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Homewood sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, BIRMINGHAM INTERNATIONAL AIRP, 8.3 miles from Homewood.

Homewood's running-cost comparison, in dollars

A 2000-square-foot house here would pull roughly 1,684 heating kilowatt-hours annually on top of cooling, totalling about $624 a year on electricity. Homewood's gas rate of 17.56 per Mcf, applied to the 22 Mcf a year the furnace burns, puts its running cost near $901 a year, against 16.62¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 48.7 years, leaving the 15-year total $659 ahead.

If your home heats with electric baseboard instead of gas

Plenty of homes in Homewood heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Homewood's answer improves. About $769 a year comes back this way, enough that the 10.4-year payback clears the $8,000 premium comfortably within the equipment's life.

Homewood against the rest of the country

Homewood lands at position 2404 out of 3206 cities on heating severity (coldest is 1), and 1432 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.

Next step for 27,919 people in Homewood

About 27,919 people live in Homewood, Alabama, 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.

Ask a local HVAC contractor for a quote before committing either way.

More on how this number was built

Nothing above is a black box: the methodology guide shows the full arithmetic behind Homewood's 3.11 seasonal COP and payback figure. At a 17.1°F design temperature, Homewood sits in cold-climate territory; the guide to that class of unit explains why.
