Should Paris switch to a heat pump?
The payback math works in Paris on paper, past the equipment's own working life. 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. Lower bills claw that back: about $101 saved annually, for a payback of roughly 34.6 years. Paris's own numbers say this pencils out only in theory, not in practice.
Why Paris's climate drives this number
Degree days tell the story here: Paris racks up 3095 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1708 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 5°F, against a record low of 3.2°F. That puts the seasonal coefficient of performance at 2.82 for the recommended cold-climate unit. Paris 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. These numbers come from KYLE OAKLEY FIELD AIRPORT, the closest NOAA station, 26 miles out.
Paris's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,779 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $587 a year. Paris's gas rate of 11.84 per Mcf, applied to the 32 Mcf a year the furnace burns, puts its running cost near $689 a year, against 13.87¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 133.4 years, leaving the 15-year total $1,982 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Paris — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $807 a year comes back this way, enough that the 9.9-year payback clears the $8,000 premium comfortably within the equipment's life.
How Paris compares nationally
Among 3206 cities, Paris's winter puts it at rank 1884 for severity, while its size puts it at rank 3088 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Paris
About 10,517 people live in Paris, Tennessee, 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.

Every constant behind this page — the 2.82 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Paris's 5°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
