Why Humble's climate drives this number
Degree days tell the story here: Humble racks up 891 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3637 cooling degree days on the cooling side. 28.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 18°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.06 on the standard unit fit for this climate. A standard ducted system is enough here; Humble's design temperature doesn't justify the cold-climate premium. These numbers come from G Bush Intercontinental Ap/Ho, the closest NOAA station, 5.8 miles out.
The yearly running costs in Humble
Electricity use for heating alone comes out to about 737 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $620 a year. Humble's gas rate of $19.42 per Mcf, applied to the 9 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $941 a year, against 16.15¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,823 ahead.
The break-even point in Humble
Because the heat pump's better air conditioning saves more electricity than its heating uses, it stays cheaper to run than the current furnace and AC in Humble at any electricity price. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $322 a year saved, a difference under $2,254 pays back within 7 years here, and under $3,220 within 10.
Electric resistance heat in Humble, compared
Not every home in Humble has gas service. Swap the comparison to resistance heat instead of gas, and Humble's answer improves. The saving here runs about $506 a year, which recovers the extra $7,500 spent going electric in roughly 14.8 years.
