Eight months of heat, and nights near 16 degrees
Council Bluffs asks a furnace to run from October through May. That is eight months of the year, and on winter nights that average 16°F, the burner is cycling on and off most of the night to hold the house steady. Most homes here heat with gas, so that furnace has to be sized and installed right the first time.
Any new non-weatherized gas furnace has to reach at least 80 percent AFUE under federal rules. Storms are part of the picture too. Pottawattamie County has seen 16 winter storms and 56 damaging wind events over the past ten years, and across Iowa, 15 percent of households lost power for 24 hours or more in 2024. A furnace installed here needs to hold up through all of that, not just a mild stretch of weather.

Iowa requires HVAC contractors to hold a state license.
The Iowa Plumbing and Mechanical Systems Board tests and keeps records on the contractor, not on each furnace they install. So the license tells you the person doing your job has passed the state's standard, but it does not mean the state signs off on this particular installation.
That sign-off comes from the local building office. Setting a new furnace needs a permit, and the work gets inspected once it is in, which matters because a gas furnace depends on a sound connection and correct venting to run safely. In Pottawattamie County, most homes heat with gas, so that inspection is the check on the part of the job that can go wrong.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your windows, and your home's layout, so there's no single number that works for every house. A contractor sizes it with a load calculation, not a quick estimate based on square feet alone. Getting this right matters here, since your furnace runs from October through May and needs to keep up on nights averaging 16°F. Too big and it short-cycles, too small and it struggles on the coldest nights, so let a contractor run the numbers for your specific house.
- How do I know it's time to replace my furnace?
- Watch for uneven heat between rooms, a furnace that's cycling on and off more than it used to, or repair calls that keep coming back. If repair costs are climbing and the furnace is getting old, replacement usually makes more sense than another fix. With 8 months of the year depending on this furnace, a breakdown in the middle of winter is a real problem, not just an inconvenience. If you're noticing any of these signs now, it's worth having a contractor look at it before it fails on you.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what your current furnace costs to run, so a contractor can walk you through the numbers for your situation. What's true everywhere is that any non-weatherized gas furnace made since November 19, 2015 has to hit at least 80 percent AFUE, so even a standard new furnace is already fairly efficient. High-efficiency models push past that, and with 70.5% of homes in Pottawattamie County heating with gas and furnaces here running 8 months a year, that difference in efficiency shows up more than it would somewhere the furnace barely gets used. A contractor can price out both options for your house so you can compare.
