Is a heat pump worth it in Harvey?

Here in Harvey, the honest answer is that a heat pump raises your annual running cost. 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). The heat pump would cost about $278 more a year to run than the furnace it replaces — a premium with no payback. That's Harvey's own climate and rates talking, not a hedge or a caveat.

Harvey's weather, in the numbers that matter

4971 heating degree days pile up here every year, so Harvey has a real but manageable winter; the cooling side runs to 864 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -5.3°F, against a record low of -10.7°F. That puts the seasonal coefficient of performance at 2.57 for the recommended cold-climate unit. A cold-climate unit is the right call in Harvey — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, LANSING MUNICIPAL AP, 7.8 miles from Harvey.

The month-to-month numbers for Harvey

Electricity use for heating alone comes out to about 4,898 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,074 a year. That compares with roughly 52 Mcf a year of gas at Harvey's 11.25 per-Mcf rate — about $796 a year — against a local electricity rate of 19.06¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $7,671 behind.

Electric resistance heat in Harvey, compared

Plenty of homes in Harvey heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,539 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 5.2 years.

Harvey against the rest of the country

Among 3206 cities, Harvey's winter puts it at rank 770 for severity, while its size puts it at rank 1945 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Next step for 19,781 people in Harvey

Harvey, Illinois is home to about 19,781 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 Harvey, nothing is lost by holding off until the current equipment genuinely fails.

Where Harvey's figure comes from

Every constant behind this page — the 2.57 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Harvey's -5.3°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
