Nine months of heat, and nights that drop to 14°F
A furnace in Green Bay works from September through May. That is nine months of the year carrying the load. On a winter night averaging 14°F, it runs long and often, and the parts inside it wear according to how many times the burner cycles on.
Any furnace installed here now has to meet 80.0 percent AFUE, the federal minimum for non-weatherized gas furnaces. Brown County has seen 22 winter storms and 78 damaging wind events over the past ten years, and most gas furnaces still need electricity to run the blower and ignition even with gas flowing. 72.3% of homes here heat with gas, and a new install is worth planning around what happens to it when the power goes out.

Wisconsin requires contractors to register with the state.
That registration puts the business on file with the state, but nobody tested them on how to size a furnace or vent it correctly. Wisconsin also blocks Brown County and its cities from layering on their own HVAC license, so this registration is the only state-level record that exists for the person doing this job.
What actually stands behind a furnace installation here is the permit process. Most cities and counties, and that includes places in Brown County, require a permit before a furnace gets replaced and an inspection once it's in. That inspection is where someone checks the gas connection and venting, the part of the job that can hurt someone if it's done wrong. With 72.3% of homes in Brown County heating with gas, that inspection is doing real work, not just paperwork.

- What size furnace does my house need?
- There is no simple number for this without a load calculation done on your actual house. A contractor measures your square footage, your insulation, your window count and type, and your home's layout, then runs what's called a Manual J calculation to find the right size. Going by square footage alone is not reliable. A furnace that is too big will short cycle and wear out faster, and one that is too small will run constantly and still not keep up when it is 14°F outside.
- How do I know it's time to replace my furnace?
- Age is one thing to look at, along with how often you are calling for repairs. If you are needing a repair every heating season, or the repair costs keep climbing, that pattern usually means the furnace is on its way out rather than just having a bad year. Homes here need heat from September through May, so a furnace that fails mid-winter can leave you without heat for a long stretch, and nights averaging 14°F make that failure hard to live with. If your furnace is getting older and you are weighing a repair against replacement, a contractor can tell you what condition it is actually in and whether it is worth fixing again.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what your current furnace is costing you to run. Every non-weatherized gas furnace made on or after November 19, 2015 has to reach at least 80 percent AFUE, so even a standard furnace today wastes less fuel than older models did. A high-efficiency furnace goes above that minimum, which matters more here since homes need heat for 9 months of the year. A contractor can walk you through the actual efficiency ratings and what fits your house, since the payoff depends on your specific furnace and how much you heat.
