Bloomington asks a lot of a furnace
Winter nights here average 24°F, and that's the low, not the exception. From October through April, seven months of the year, your furnace is the thing standing between your house and that cold.
A new furnace installed here has to be sized for those nights, not just an average day. If it's a gas furnace, federal rules set the floor at 80.0 percent AFUE, but Bloomington's winters are long enough that what you install matters for the whole stretch, not just the coldest week. Power matters too. Indiana saw 17% of households lose power for 24 hours or more in 2024, and the last ten years brought 9 winter storms and 44 damaging wind events to this area. Whatever heats your home, it's worth knowing how it holds up when the power doesn't.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Indiana leaves HVAC licensing to the counties and cities, so whether the installer needs a local license depends on Monroe County's own rule, not a state one. There is no state record of testing or credentials behind the person installing your furnace. Any protection here comes from whatever Monroe County requires of contractors working inside its lines.
For a furnace install, the permit process is what stands in for a license. Most cities and counties require a permit from the local building office before the old furnace comes out, and an inspection once the new one is in. That inspection is what checks the gas connection and venting, the part of the job that can hurt someone if it is done wrong. Where the state leaves licensing to the county, the permit and inspection are the record that the work was done and checked.

- What size furnace does my house need?
- That depends on the size of your house, how well it's insulated, how many windows it has, and a few other things about how it was built. A contractor works this out with a load calculation, not a chart based on square footage alone. Too big and the furnace short cycles, heating the house in bursts and wearing out faster. Too small and it runs constantly through the winter without keeping up. Have a contractor measure your house rather than guess from its size.
- How do I know it's time to replace my furnace?
- Watch for rising repair calls, uneven heat between rooms, and a furnace that keeps needing attention each winter. If parts are getting harder to source, or you're calling for repairs more than once a season, replacement starts to make more sense than another fix. A furnace here needs to run October through April, seven months of the year, so a unit that struggles now will struggle more as it ages. A contractor can tell you whether what you're seeing is normal wear or the start of the end.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you're running the furnace now. Homes here need heat seven months a year with winter nights averaging 24°F, so a furnace here does more work than one in a milder climate. Furnaces made since November 2015 already have to hit 80 percent AFUE at minimum, and high-efficiency models go well above that, so the question is really how much more you'd get and whether the difference matters for your house. A contractor can walk through the actual models and what each one would mean for your situation.
