Ottawa, KS: the heat pump payback math
In Ottawa, the extra upfront cost technically comes back, just not before the equipment wears out. 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. Lower bills claw that back: about $138 saved annually, for a payback of roughly 25.3 years. That's a technicality, not a recommendation, for anyone actually living in Ottawa.
Ottawa's weather, in the numbers that matter
Ottawa has a real but manageable winter — 3895 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1625 cooling degree days. Sizing runs off the design temperature, not the average day: -4°F here (record low -8°F), which works out to a seasonal COP of 2.6 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, Ottawa sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from NEW CENTURY AIRCENTER ARPT, the closest NOAA station, 25.8 miles out.
The month-to-month numbers for Ottawa
Electricity use for heating alone comes out to about 3,793 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $779 a year. Ottawa's gas rate of 14.81 per Mcf, applied to the 41 Mcf a year the furnace burns, puts its running cost near $918 a year, against 15.05¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 97.6 years, for a 15-year net position $1,425 behind.
The other scenario: no gas furnace to begin with
Not every home in Ottawa has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,022 a year comes back this way, enough that the 7.8-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Ottawa ranks in this dataset
Among 3206 cities, Ottawa's winter puts it at rank 1587 for severity, while its size puts it at rank 2689 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
Deciding what's next in Ottawa, KS
Ottawa, Kansas is home to about 12,733 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 Ottawa, nothing is lost by holding off until the current equipment genuinely fails.

Where Ottawa's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Ottawa's 2.6 seasonal COP and payback figure. At a -4°F design temperature, Ottawa sits in cold-climate territory; the guide to that class of unit explains why.
