Should Waverly switch to a heat pump?

Here in Waverly, 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 $110 a year HIGHER than the furnace it replaces, so that premium is never recovered. That's Waverly's own climate and rates talking, not a hedge or a caveat.

Waverly's weather, in the numbers that matter

Waverly has a cold winter that leans hard on heating equipment — 5493 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 982 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -13°F, against a record low of -15°F. That puts the seasonal coefficient of performance at 2.39 for the recommended cold-climate unit. A cold-climate unit is the right call in Waverly — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from WATERLOO MUNICIPAL AIRPORT, the closest NOAA station, 12.1 miles out.

The month-to-month numbers for Waverly

Electricity use for heating alone comes out to about 5,820 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $886 a year. That compares with roughly 57 Mcf a year of gas at Waverly's 10.61 per-Mcf rate — about $776 a year — against a local electricity rate of 13.31¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $5,145 behind.

If your home heats with electric baseboard instead of gas

Plenty of homes in Waverly heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Waverly's answer improves. About $1,135 a year comes back this way, enough that the 7.1-year payback clears the $8,000 premium comfortably within the equipment's life.

Waverly against the rest of the country

Waverly lands at position 384 out of 3206 cities on heating severity (coldest is 1), and 3074 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 10,576 people in Waverly

Waverly, Iowa is home to about 10,576 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 Waverly, nothing is lost by holding off until the current equipment genuinely fails.
