Eight months of heat, down to 18 degrees
Furnaces in Lapeer County run October through May. That is eight months of the year the burner needs to work, on nights that average 18°F. A new furnace here has to hold up to a long season, not a mild one.
Most homes in the county heat with gas, so when the power goes out, the furnace is still the thing keeping the house warm. Michigan saw 17 winter storms and 65 damaging wind events over the past ten years, and in 2024, over a third of households in the state lost power for at least 24 hours. Any furnace installed today has to be set up for what this county actually asks of it. Non-weatherized gas furnaces built since November 2015 are required to reach at least 80 percent AFUE, and that is the floor to plan from, not the target.

Michigan requires HVAC contractors to hold a state license.
That license is held by the contractor as a business, not issued fresh for each furnace they install. It means the state has tested the contractor and keeps a record of them, so if something goes wrong there is a name on file and a license that can be checked and, if the work warrants it, pulled.
For this job, the license is what stands behind the contractor's qualifications, but the furnace itself still gets checked separately. A new furnace install in Lapeer County needs a permit from the local building office and an inspection once the work is done, which is where the gas connection gets looked over by someone other than the person who made it. With most homes in the county heating with gas, that inspection is the step that catches a bad line before the furnace is ever fired up.

- What size furnace does my house need?
- There's no single number that applies to every house. It comes down to your square footage, how well the house is insulated, your ceiling height, window count, and how the place is laid out. A contractor works this out with a load calculation, not a chart based on home size alone. Getting this right matters here especially, since your furnace runs from October through May and needs to keep up on nights averaging 18°F. Too big and it'll short cycle, too small and it won't keep up when the cold really sets in.
- How do I know it's time to replace my furnace?
- Start by looking at how old the furnace is and how often you're calling for repairs. If breakdowns are happening more than once a season, or the parts being replaced keep getting more expensive, that's a sign the furnace is on its way out. Watch too for uneven heat between rooms, a furnace that runs longer to reach the same temperature, or a gas bill that's climbing with no clear reason. With heat needed here eight months out of the year, a furnace that's struggling doesn't get much of a break to fail gracefully.
- 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. Any furnace built since November 2015 has to hit at least 80 percent AFUE, so the real question is whether it makes sense to go higher than that. A furnace that burns less gas to make the same heat adds up over eight months of heating a year here. A contractor can look at your current setup and tell you what the difference would actually mean for your house.
