Boone County asks a lot of a furnace
Furnaces here run from October through May. That's 8 months of the year, with winter nights averaging 14°F. A furnace going in now has to handle that stretch without much of a break.
Any new gas furnace has to meet a federal minimum of 80 percent AFUE, so the question is what you install above that floor. Power matters too. Iowa saw 15% of households lose power for 24 hours or more in 2024, and the last ten years brought 25 winter storms and 37 damaging wind events to this area. A furnace that starts back up reliably after an outage isn't a small detail here.

Iowa requires HVAC contractors to hold a state license.
The state tests HVAC contractors and puts them on record through the Iowa Plumbing and Mechanical Systems Board. That license belongs to the contractor, not to any one job, so it tells you this person met the state's standard before they ever showed up at your door, but it doesn't mean the state signs off on your furnace once it's in.
That's where the local building office comes in. A furnace installation needs a permit and an inspection once the work is done, and that's the check that catches a bad gas connection or a venting mistake before it becomes a problem you live with. In Boone County, most homes run on gas heat, so that inspection is doing real work here, not just paperwork.

- What size furnace does my house need?
- The right size depends on your home's square footage, how well it's insulated, your window count and type, and your ceiling height. A furnace that's too big cycles on and off too fast and never runs long enough to heat evenly. One that's too small runs constantly and still can't keep up on the coldest nights, and with lows averaging 14°F here in the winter, undersized is the mistake you'll feel most. A contractor sizes it with a load calculation on your actual house, not a chart based on square footage alone.
- How do I know it's time to replace my furnace?
- Age is the first sign. Once a furnace is old enough that repairs are getting more frequent, replacing it is usually the better call than patching it again. Watch for uneven heat between rooms, a furnace that runs longer than it used to, or a jump in your gas bill with no other explanation. Homes here need heat from October through May, eight months of the year, so a furnace that struggles in that stretch is one you'll notice failing sooner rather than later.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you'd save on gas over that time, and a contractor can walk you through those numbers for your situation. What's true everywhere is that any furnace made since November 2015 already has to hit at least 80 percent AFUE, so the real choice is between that baseline and a high-efficiency model rated higher. With 57.3 percent of homes in the county heating with gas and eight months of the year needing heat, the furnace runs a lot here, which is exactly the condition that makes higher efficiency add up faster.
