Eight months of heat, and nights that drop to 15 degrees
Cedar Rapids homes need a working furnace from October through May. That's 8 months a year. Winter nights average 15°F from December through February, and a new furnace has to hold that line every one of those nights.
Most homes here heat with gas, and any non-weatherized gas furnace built after November 2015 has to reach at least 80 percent AFUE by federal rule. Linn County has also logged 30 winter storms and 156 damaging wind events over the past ten years, and 15% of Iowa households went at least 24 hours without power in 2024. A furnace installed here needs to be sized for a long season, and the home needs a plan for the nights the power doesn't hold.

Iowa requires HVAC contractors to hold a state license.
The Iowa Plumbing and Mechanical Systems Board tests and licenses HVAC contractors statewide, and the license belongs to the contractor, not to any single job. That means the person running the crew on your furnace has already been checked by the state, and the state keeps a record of who they are.
For a furnace installation, that license is what stands behind the work itself. On top of it, most cities and counties in Iowa require a permit for a furnace replacement, with an inspection once the job is done, so someone outside the contractor's own crew looks at the finished work. Furnace installs also involve a gas connection, and a bad one is the most dangerous part of the job. In Linn County, where 74 percent of homes heat with gas, that inspection is what catches a connection done wrong.

- What size furnace does my house need?
- There is no single number that works for every house. A contractor sizes your furnace with a load calculation that accounts for your square footage, insulation, windows, and how the house holds heat through winter nights that average 15°F here. Guessing on size backfires either way. Too small and it runs constantly without keeping up. Too big and it short cycles, wearing out parts faster and leaving rooms uneven.
- How do I know it's time to replace my furnace?
- If your furnace is struggling to keep the house warm, cycling on and off more than it used to, or needing repairs every winter, it's time to start planning a replacement. Age matters, especially here, where the furnace has to run from October through May, eight months of the year. Rising gas bills with no other explanation, or a carbon monoxide detector that's gone off, are signs not to wait. A contractor can tell you whether a repair still makes sense or whether you're past that point.
- 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. Every new non-weatherized gas furnace sold today has to reach at least 80.0 percent AFUE by law, so the real choice is between that baseline and a higher-efficiency model above it. Most homes in Linn County heat with gas, and with heat needed here from October through May, the difference in gas use over a season like that adds up. A contractor can walk through the actual models and what each one means for your house.
