Lansing furnaces run eight months a year
From October to May your furnace is the thing standing between your house and a winter that averages 19°F at night. That is most of the year spent leaning on one machine.
More than two thirds of homes here heat with gas, and any new furnace installed has to meet the federal minimum of 80 percent AFUE. Ingham County has also seen 12 winter storms and 21 damaging wind events over the past ten years, and across Michigan more than a third of households lost power for at least 24 hours in 2024. A new furnace should be sized and installed to hold up through that kind of winter, not just get through a mild one.

Michigan requires HVAC contractors to hold a state license.
The license is held by the contractor, not tied to this one job. It comes from the Board of Mechanical Rules, which tests and records the people who hold it, so a licensed contractor has already had their qualifications checked by the state before they ever get to your furnace.
For a furnace installation, that license is what stands behind the work, but it is not the only check. Most cities and counties, including here, require a permit from the local building office for a furnace replacement, along with an inspection once the job is done. That inspection is what catches a bad gas connection or a venting mistake, the kind of error that matters most in a job like this. With most homes in Ingham County heating with gas, that inspection is doing real work, not just paperwork.

- 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 is no single number that works for every house. A furnace that is too big will short cycle, turning on and off before it heats evenly, and one that is too small will run constantly and still leave rooms cold. A contractor sizes this with a load calculation, not a chart based on square footage alone. With winter nights here averaging 19°F, getting the size right matters more than in milder climates, since an undersized unit has less room to keep up on the coldest nights.
- How do I know it's time to replace my furnace?
- If your furnace is breaking down more than once a season, or costing more to run than it used to, it is time to start planning a replacement. Watch for uneven heating room to room, a burner flame that looks yellow instead of blue, and repair bills that keep coming back. Homes here need heat from October through May, eight months of the year, so a furnace that fails mid-winter leaves you without heat when you need it most. Replacing on your schedule, rather than after a breakdown, gives you time to size and choose the unit properly instead of taking whatever can be installed fastest.
- 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, but in a place that needs heat for eight months a year, the efficiency difference adds up more than it would somewhere milder. Every non-weatherized gas furnace built since November 2015 has to reach at least 80 percent AFUE, so even a standard new furnace is already efficient by older standards. High-efficiency models push past that baseline, meaning less of the gas you burn is lost out the vent. A contractor can walk through your current furnace's rating against what's available now and help you weigh the difference for your specific house.
