Kosciusko County asks a lot of a furnace
Your furnace here runs eight months a year, October through May, and on winter nights that average 20°F it's working hard to keep up. That long a season adds up in cycles on the burner and the parts that light it.
Most homes in the county heat with gas, and any new gas furnace has to meet the federal minimum of 80 percent AFUE. Wind is the bigger risk to plan around here, with 117 damaging wind events logged over the past ten years against just 2 winter storms. Statewide, 17 percent of households lost power for at least a day in 2024, so a furnace that can start back up on its own after an outage matters.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Indiana leaves HVAC licensing to counties and cities, so whether a contractor needs a license here depends on Kosciusko County's own rule, not any state one. A license means the county tested the contractor and keeps a record of them. A registration just means the business is on file, with nothing tested. Either way, there is no statewide license to point to here, only whatever the county or city requires.
For a furnace installation, most cities and counties require a permit from the local building office and an inspection once the work is done. That permit and inspection are what stand between this job and no oversight at all, not a license. In Kosciusko County, 65.6% of homes heat with gas, and a furnace installation includes the gas connection, which is the part of this job an inspection exists to check.

- What size furnace does my house need?
- It depends on your square footage, insulation, ceiling height, and how many windows the house has, so there is no single number that works for every home. A contractor works this out with a load calculation, not a tape measure alone. Guessing high seems safe but it is not. An oversized furnace cycles on and off too fast, which wears out parts sooner and leaves rooms uneven. With winter lows here averaging 20°F, a furnace that is sized right will still keep up on the coldest nights without running nonstop.
- How do I know it's time to replace my furnace?
- Age is the first thing to look at. As a furnace gets older, repairs start costing more and fixing less. Watch for rooms that heat unevenly, a furnace that short cycles, or a rise in your gas bill with no other explanation. Homes here need heat from October through May, eight months a year, so a furnace on its way out gets tested hard for most of the year. If a contractor has been out for the same repair more than once this season, replacing it is usually the better call.
- Is a high-efficiency furnace worth it?
- It depends on what your furnace is doing now and how long you plan to stay in the house. Every non-weatherized gas furnace made since November 2015 has to hit at least 80 percent AFUE, so even a standard model today wastes less gas than an old one might have. A high-efficiency furnace pulls more heat out of the same fuel, which matters most in a place where the furnace runs eight months a year. A contractor can tell you what your current furnace is rated and whether stepping up makes sense for your house.
