HeatPumpPayback

Should Riverview switch to a heat pump?

Here in Riverview, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Riverview 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. The heat pump would cost about $304 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Riverview's numbers say wait.

Why Riverview's climate drives this number

5067 heating degree days pile up here every year, so Riverview has a cold winter that leans hard on heating equipment; the cooling side runs to 786 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 3.6°F, against a record low of -1.7°F. That puts the seasonal coefficient of performance at 2.79 for the recommended cold-climate unit. Riverview 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.

The month-to-month numbers for Riverview

Electricity use for heating alone comes out to about 4,599 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,092 a year. The gas furnace it replaces burns roughly 53 Mcf a year at 10.92 per Mcf here, for a running cost near $787 a year (electricity here runs 20.72¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $8,066 behind.

If your home heats with electric baseboard instead of gas

Gas isn't universal in Riverview — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Riverview's answer improves. The saving here runs about $1,778 a year, which recovers the extra $8,000 spent going electric in roughly 4.5 years.

Where Riverview ranks in this dataset

Riverview lands at position 618 out of 3206 cities on heating severity (coldest is 1), and 2808 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.

Next step for 12,011 people in Riverview

About 12,011 people live in Riverview, Michigan, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

Ask a local HVAC contractor for a quote before committing either way.

More on how this number was built

Every constant behind this page — the 2.79 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Riverview's 3.6°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
