Should Danville switch to a heat pump?

In Danville, a heat pump would cost more to run each year than what you have now. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Running costs here land $59 a year HIGHER than the furnace it replaces, so that premium is never recovered. That's Danville's own climate and rates talking, not a hedge or a caveat.

How cold Danville actually gets

Degree days tell the story here: Danville racks up 4073 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1379 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 0°F, against a record low of -4°F. That puts the seasonal coefficient of performance at 2.7 for the recommended cold-climate unit. Danville needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

What it actually costs to run, year to year

A 2000-square-foot house here would pull roughly 3,820 heating kilowatt-hours annually on top of cooling, totalling about $851 a year on electricity. Danville's gas rate of 11.49 per Mcf, applied to the 42 Mcf a year the furnace burns, puts its running cost near $792 a year, against 17.03¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $4,385 behind.

The other scenario: no gas furnace to begin with

Gas isn't universal in Danville — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $1,210 a year comes back this way, enough that the 6.6-year payback clears the $8,000 premium comfortably within the equipment's life.

Danville against the rest of the country

Ranked against the other 3206 cities covered, Danville comes in at 1478 for heating severity — 1 would be the coldest place in the dataset — and 2725 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

What to do with this number in Danville

Danville, Indiana is home to about 12,532 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Danville, nothing is lost by holding off until the current equipment genuinely fails.

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