Will a heat pump pay off in Livonia, MI?
Here in Livonia, the honest answer is that a heat pump raises your annual running cost. 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. Running costs here land $300 a year HIGHER than the furnace it replaces, so that premium is never recovered. That's Livonia's own climate and rates talking, not a hedge or a caveat.
How cold Livonia actually gets
Degree days tell the story here: Livonia racks up 5000 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 928 cooling degree days on the cooling side. 1.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -2.9°F on file. Worked through the model, that's a seasonal COP of 2.75 on the cold-climate unit fit for this climate. Livonia 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. Climate figures trace to the nearest NOAA station, DETROIT METRO WAYNE COUNTY AI, 11.7 miles from Livonia.
The month-to-month numbers for Livonia
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,604 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,118 a year. That compares with roughly 52 Mcf a year of gas at Livonia's 10.92 per-Mcf rate — about $818 a year — against a local electricity rate of 20.72¢/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 $8,000 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Livonia heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Livonia's answer improves. Switching saves about $1,755 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 4.6 years.
Where Livonia ranks in this dataset
Among 3206 cities, Livonia's winter puts it at rank 692 for severity, while its size puts it at rank 373 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.
Deciding what's next in Livonia, MI
Livonia, Michigan is home to about 93,113 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 Livonia, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.

Every constant behind this page — the 2.75 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Livonia's 1.9°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.
