South Bend asks a lot of a furnace
Eight months of the year, October through May, your furnace is what keeps the house livable here. Winter nights average 20°F, and most homes in the area run on gas heat to get through them.
A new furnace installed here has to be built for that stretch, not just the coldest week of it. Any non-weatherized gas furnace made since November 2015 has to reach at least 80 percent AFUE, so that floor is already set. What matters more is sizing it and installing it right for a season that runs eight months long, with wind and winter storms that have knocked out power across Indiana more than once.

In Indiana, HVAC licensing for homes is left to the counties and cities.
St. Joseph County sets its own rule rather than following a state license, so what applies to this job depends on the local building office rather than a state board. Where a county or city does license, that record is on file with them, not with the state of Indiana.
For a furnace installation, most cities and counties require a permit from the local building office and an inspection once the work is done, and that is where the protection here comes from. A furnace runs on gas, and the connection is the part worth having checked. In St. Joseph County, 81% of homes heat with gas.

- What size furnace does my house need?
- There is no single number that works for every house. It depends on your square footage, your insulation, your ceiling height, and how many windows you have facing the wind. A furnace that is too big will short cycle, heating your house in quick bursts and shutting off before it evens out room to room. One that is too small will run constantly and still lose ground on the coldest nights, and here that means nights near 20°F. A contractor needs to walk through the house and run a load calculation. That is not something you can safely guess from square footage alone.
- How do I know it's time to replace my furnace?
- Age is the first thing to look at. If your furnace has been running a long time, a repair now may just be a delay before the next one. Watch for signs alongside the age. Rooms that used to heat evenly and now do not, a furnace that cycles on and off more than it used to, or a gas smell you notice when it starts up all mean it is time to have it looked at. Homes here need heat from October through May, so a furnace that is struggling has eight months a year to fail you, and a breakdown on a night near 20°F is worse than one in October.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you run the furnace now. Every new non-weatherized gas furnace has to hit at least 80 percent AFUE by law, so that is your floor. High-efficiency models go well above that, wasting less gas for the same heat. With 81 percent of homes here heating with gas and a heating season that runs eight months, the difference in gas use adds up over a winter more than it would somewhere milder. A contractor can walk you through the actual models and what each one would mean for your specific furnace and duct setup.
