Heat Pump Payback in Marshall, TX
Marshall, TX: the heat pump payback math
Marshall technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Marshall would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $304 saved annually, for a payback of roughly 18.1 years. That's a technicality, not a recommendation, for anyone actually living in Marshall.

Marshall's weather, in the numbers that matter
1826 heating degree days pile up here every year, so Marshall has a mild winter by US standards; the cooling side runs to 2393 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 19.2°F, and the coldest daily reading in the 2024 station record was 9°F. That puts the seasonal coefficient of performance at 3.16 for the recommended cold-climate unit. Mild on average, but the occasional cold snap is what sizes the equipment: at a 19.2°F design temperature Marshall falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe. These numbers come from Harrison County Airport, the closest NOAA station, 2.9 miles out.
Marshall's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 1,463 heating kilowatt-hours annually on top of cooling, totalling about $566 a year on electricity. That compares with roughly 19 Mcf a year of gas at Marshall's $19.42 per-Mcf rate, about $870 a year with the old AC included, against a local electricity rate of 16.15¢/kWh. If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $935 behind.
How sensitive Marshall's result is to prices
Gas would only overtake the heat pump in Marshall if electricity rose past 91.8¢/kWh from 16.15¢, or gas fell under $3.42 per Mcf from $19.42. A useful quote test for Marshall: the heat pump is worth it within a decade if it costs less than $3,040 more than replacing the furnace and AC, and within 7 years if the gap is under $2,128.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Marshall, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Marshall's answer improves. About $682 a year comes back this way, enough that the 14.7-year payback clears the $10,000 premium comfortably within the equipment's life.
How Marshall compares nationally
Marshall lands at position 2528 out of 3206 cities on heating severity (coldest is 1), and 1650 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.
Deciding what's next in Marshall, TX
Marshall, Texas is home to about 24,263 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 Marshall, nothing is lost by holding off until the current equipment genuinely fails.

Every constant behind this page, the 3.16 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Marshall's 19.2°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
