Eight months of heat, and nights that drop to 19°F
Jackson County homes run their furnace from October through May. That is eight months a year, and on winter nights that average 19°F, the furnace is doing real work to keep the house warm, not just taking the edge off.
Most homes here heat with gas, and any new non-weatherized gas furnace has to reach at least 80 percent AFUE under federal rule. The county has also logged 13 winter storms and 31 damaging wind events over the past ten years, and across Michigan more than a third of households went at least 24 hours without power in 2024. A furnace installed here has to carry a long season and keep working through the storms that come with it.

Michigan requires HVAC contractors to hold a state license.
The state tests contractors before it licenses them, and the license belongs to the contractor, not to any single job. That means the person or company doing the work has already been checked once by the state, and the state keeps a record of who they are. It does not mean every furnace install is inspected by the state itself. The license is the baseline. What happens on your job gets checked separately.
For a furnace install, the licensing tells you the contractor cleared that bar. What covers the installation itself is the local permit and inspection, required in most cities and counties in Michigan when a furnace is replaced. That inspection is where someone checks the gas connection and venting, the part of the job that matters most in a county where 71.4% of homes heat with gas.

- What size furnace does my house need?
- It depends on your home's square footage, insulation, window count, and layout, so there is no single answer that fits every house. A contractor works this out with a load calculation, which looks at how much heat your home actually loses on a cold night rather than a rough estimate based on size alone. Going bigger than you need does not mean more comfort. An oversized furnace cycles on and off more often and wears out sooner, while one sized correctly runs longer, steadier cycles and heats the house evenly. With winter nights here averaging 19°F, getting the size right matters more than it would somewhere milder.
- How do I know it's time to replace my furnace?
- Watch how the furnace is behaving, not just how old it is. Uneven heat between rooms, a furnace that cycles more often than it used to, or a jump in gas usage without a change in weather all point to a system losing ground. If the same repair keeps coming back, or a technician finds a major part like the heat exchanger has failed, replacement usually makes more sense than paying for another repair. Homes here need heat from October through May, eight months of the year, so a furnace that's already struggling has a long stretch ahead of it.
- Is a high-efficiency furnace worth it?
- It depends on how much you heat your home and what furnace you have now. Every non-weatherized gas furnace made since November 19, 2015 has to reach at least 80 percent AFUE, so the real question is whether it makes sense to go higher than that baseline. A higher AFUE means less gas burned for the same amount of heat, and with 71.4 percent of homes here heating with gas across an eight-month heating season, that difference adds up. A contractor can walk through specific models and what each one would mean for your house and your current furnace.
