Eight months of heat, and winter nights near 18°F
Your furnace in Midland County works from October through May. That's eight months a year the burner has to be ready to fire. Winter nights average 18°F, and on the coldest nights it runs for hours at a stretch to keep up.
Most homes here heat with gas, and any new gas furnace has to meet a federal minimum of 80 percent AFUE. The county has also logged 15 winter storms and 50 damaging wind events over the past ten years, and in 2024, over a third of Michigan households lost power for at least 24 hours. A furnace that starts back up on its own when the power returns matters here.

Michigan requires HVAC contractors to hold a state license.
Michigan licenses HVAC contractors through the Board of Mechanical Rules. The license is issued to the contractor, not to this specific job, so the state has tested and approved the person or company taking it on, and that approval stays with them across every job they do.
For a furnace installation, that license is what stands behind the work. In most cities and counties, the local building office also needs to issue a permit for the job and send someone to inspect it once it's done. That inspection matters here, since 65.5% of homes in Midland County heat with gas, and a furnace hooked up wrong is a gas safety problem before it's anything else.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your windows, and how your house is laid out, so there's no single number that fits every home. A contractor works this out with a load calculation, not a chart based on square footage alone. With winter lows here averaging 18°F and homes needing heat from October through May, getting the size right matters more than it would somewhere milder. Too small and it runs constantly without keeping up. Too large and it short-cycles, wearing out parts faster and leaving the house feeling uneven.
- How do I know it's time to replace my furnace?
- Watch for rising repair calls, uneven heat from room to room, and a furnace that's simply old. Once a furnace has years behind it, parts start wearing out faster than they're worth fixing one at a time. If yours is cycling on and off more than it used to, or the burner flame looks yellow instead of blue, have it looked at. With heat needed here from October through May, a furnace that's struggling early in the season is only going to get worse as the lows settle in around 18°F.
- Is a high-efficiency furnace worth it?
- Any furnace installed today has to meet at least 80 percent AFUE, since that's the federal minimum for new non-weatherized gas furnaces. High-efficiency models go further, some reaching the mid-90s, which means less heat lost out the flue and more of the gas you burn actually warming the house. Whether the higher upfront model pays off for you depends on your gas rates and how long you plan to stay in the house, and a contractor can walk through those numbers for your specific situation. Given that 65.5 percent of homes here heat with gas and the season runs eight months long, the efficiency difference gets more use here than it would somewhere with a shorter winter.
