Is a heat pump worth it in Celina?
This one's marginal in Celina: it only clears if you stay long enough. $3,500 is what Celina would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. That premium is recovered through $341 of lower running costs every year, landing the payback clock at roughly 10.3 years. It's a genuine toss-up here — Celina's numbers don't point clearly either way.
Celina's weather, in the numbers that matter
Degree days tell the story here: Celina racks up 1985 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2940 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 12°F, against a record low of 9°F. That puts the seasonal coefficient of performance at 2.99 for the recommended cold-climate unit. A cold-climate unit is the right call in Celina — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from MCKINNEY MUNICIPAL ARPT, the closest NOAA station, 14.9 miles out.
The month-to-month numbers for Celina
Electricity use for heating alone comes out to about 1,681 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $676 a year. Celina's gas rate of 19.42 per Mcf, applied to the 21 Mcf a year the furnace burns, puts its running cost near $1,017 a year, against 16.15¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 39.6 years, leaving the 15-year total $1,608 ahead.
The other scenario: no gas furnace to begin with
Not every home in Celina has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $751 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 10.7 years.
How Celina compares nationally
Among 3206 cities, Celina's winter puts it at rank 2430 for severity, while its size puts it at rank 788 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
Deciding what's next in Celina, TX
Celina, Texas is home to about 51,661 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 Celina, nothing is lost by holding off until the current equipment genuinely fails.

Where Celina's figure comes from
Every constant behind this page — the 2.99 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Celina's 12°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
