Is a heat pump worth it in St. Cloud?

In St. Cloud, a heat pump would cost more to run each year than what you have now. $3,500 is what St. Cloud 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. Unfortunately the electric bill outweighs the gas bill it replaces by about $274 a year here, so the extra spend stays unrecovered. That's St. Cloud's own climate and rates talking, not a hedge or a caveat.

St. Cloud's weather, in the numbers that matter

Degree days tell the story here: St. Cloud racks up 6689 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 582 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: -9.9°F here (record low -14.1°F), which works out to a seasonal COP of 2.46 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, St. Cloud sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, ST CLOUD REGIONAL AIRPORT, 5.9 miles from St. Cloud.

What it actually costs to run, year to year

Modelled on a typical 2000-square-foot house, the heat pump draws about 6,885 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,157 a year. The gas furnace it replaces burns roughly 70 Mcf a year at 10.98 per Mcf here, for a running cost near $883 a year (electricity here runs 15.67¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $7,603 behind.

The other scenario: no gas furnace to begin with

Not every home in St. Cloud has gas service. Swap the comparison to resistance heat instead of gas, and St. Cloud's answer improves. The saving here runs about $1,616 a year, which recovers the extra $8,000 spent going electric in roughly 5 years.

Where St. Cloud ranks in this dataset

Ranked against the other 3206 cities covered, St. Cloud comes in at 61 for heating severity — 1 would be the coldest place in the dataset — and 534 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Deciding what's next in St. Cloud, MN

St. Cloud, Minnesota is home to about 72,145 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 St. Cloud, nothing is lost by holding off until the current equipment genuinely fails.

Where St. Cloud's figure comes from

Every constant behind this page — the 2.46 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. St. Cloud's -9.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
