Eight months of heat in Warren County
October through May, your furnace is what stands between your family and a Warren County winter. Nights average 17°F from December through February, and that is the kind of cold a furnace runs against for eight months a year, not just a few cold snaps.
More than half the homes here heat with gas, and a new furnace installed today has to meet 80.0 percent AFUE if it runs on gas and isn't weatherized. That is the federal floor, not a feature. The county has also logged 21 winter storms and 66 damaging wind events over the past ten years, the kind of weather that knocks out power. In Iowa, 15 percent of households lost power for at least 24 hours in 2024. A furnace with a standing pilot will still light without electricity. One that needs power for its ignition system will not.

Iowa requires HVAC contractors to hold a state license.
The license is held by the contractor, not tied to your address or to this one job. Iowa's Plumbing and Mechanical Systems Board is the body that licenses HVAC contractors in this state, and that license covers the contractor rather than each job they do.
For a furnace install, that license is what stands behind the work. In most cities and counties the job also needs a permit from the local building office, with an inspection once the furnace is in place. More than half the homes in Warren County heat with gas, so a furnace install here is common work, not an unusual one.

- What size furnace does my house need?
- The right size 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 furnace that's too big will short cycle, heating fast then shutting off before it warms the house evenly. One that's too small will run constantly and still struggle on the coldest nights, and with winter lows here averaging 17°F, undersized equipment shows its limits fast. A contractor will run a load calculation on your actual house, not just its square footage, to land on the right size.
- How do I know it's time to replace my furnace?
- Rising repair costs, uneven heat between rooms, and a furnace running most of the day are the main signs. Homes here need heat from October through May, eight months of the year, so a furnace under strain doesn't get much rest. If yours is cycling on and off more than it used to, or the burner flame looks yellow instead of blue, those point to a unit working harder than it should. A furnace over 15 years old that needs a major repair is usually worth replacing rather than fixing again.
- Is a high-efficiency furnace worth it?
- It depends on how much you run your furnace and what you're replacing. Any non-weatherized gas furnace made for sale here since November 2015 already has to reach at least 80 percent AFUE, so a high-efficiency model is measured against that floor, not against nothing. With eight months of heating season and winter nights averaging 17°F, a furnace here logs a lot of hours, which is exactly the condition where efficiency differences add up over time. A contractor can walk you through what each option means for your specific house.
