Eight months of heating in Carmel
Winter nights here average 22°F, and homes need heat from October through May, eight months of the year. A new furnace has to start reliably on the cold nights, not just the mild ones in between.
Most homes in Carmel heat with gas, and any new non-weatherized gas furnace has to reach at least 80 percent AFUE under federal rules. Hamilton County has logged 11 winter storms and 69 damaging wind events over the past ten years. A gas furnace with a standing pilot keeps running through a power outage. One with electronic ignition will come back on by itself once the power returns.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Indiana leaves the licensing question to Hamilton County itself, so there is no state license number and no state board keeping a file on the contractor. Whatever rule applies here, whether that is a county license, a registration, or nothing at all, comes from local government, not the state.
For a furnace install, the permit stands in for a license. Most cities and counties require a permit from the local building office before the furnace goes in, and an inspection once it is done. That inspection is where a bad gas connection gets caught, since that is the dangerous part of a furnace job. In Hamilton County, where 60.8% of homes heat with gas, that inspection is doing real work.

- What size furnace does my house need?
- The right size comes from a load calculation, not from the square footage of your house alone. A contractor works out how much heat your house loses through its walls, windows, and roof, then matches that to a furnace output in BTUs. Too big and it short cycles, heating fast then shutting off before the house feels even. Too small and it runs nonstop through the coldest months and still can't keep up. With winter nights here averaging 22°F, that calculation matters more than it does somewhere milder, since an undersized furnace has less room for error.
- How do I know it's time to replace my furnace?
- Age is the first thing to check, alongside how the furnace has been running. A furnace working hard for 8 months a year, October through May, wears out faster than one running just a few months, so an older unit deserves closer attention than a newer one. Watch for rising bills with no other explanation, rooms that used to heat evenly now running cold, and a burner that cycles on and off more than it used to. If a repair is priced close to what a new furnace would cost, that's usually the point where replacement makes more sense than another fix.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you're already spending to heat it. Every non-weatherized gas furnace built since November 2015 has to hit at least 80 percent AFUE, so even a standard model today isn't wasteful. A high-efficiency furnace goes beyond that minimum, turning more of the gas you burn into heat that reaches your house, and with 60.8 percent of homes here heating with gas and a heating season that runs 8 months long, that difference gets used a lot. A contractor can walk through the actual models and what each one would cost installed for your house.
