Eight months of heat, and winter nights near 21 degrees
Fort Wayne homes need a working furnace from October through May, eight months of the year. On winter nights the temperature averages 21°F, and the furnace has to hold that line night after night for most of the year.
Most homes here heat with gas, and any non-weatherized gas furnace built since November 2015 has to reach at least 80 percent AFUE by federal rule. Allen County has also seen its share of winter storms and damaging wind over the past ten years, and outages come with that. Worth keeping in mind when you decide what kind of furnace and thermostat setup goes into your house.

In Indiana, HVAC licensing for homes is left to the counties and cities.
Allen County sets its own rule rather than following a state license, so whether a contractor is licensed depends on the county's own requirements, not a state record. There is no state board testing or tracking HVAC contractors here. What protection exists comes from what the county itself requires, and that is worth knowing before the work starts.
For this furnace installation, the piece that matters most is the permit and inspection from the local building office, which most cities and counties require for this kind of job. That inspection is what checks the gas connection, the flue, and the rest of the install after the work is done. With most homes in Allen County heating with gas, that inspection is the step that catches a bad connection before it becomes dangerous.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your windows, and your ceiling height, so there isn't one number that fits every house. A contractor works this out with a load calculation, not a quick per-square-foot guess, because two houses the same size can need different sized furnaces. Getting the size wrong matters here, since your furnace runs from October through May. Too small and it struggles on the 21°F nights. Too big and it short cycles instead of heating evenly. Have a contractor measure your house and calculate the load before you buy anything.
- How do I know it's time to replace my furnace?
- Watch for rooms that won't heat evenly, a furnace that cycles on and off more than it used to, or repair calls that keep coming back. An aging heat exchanger can crack, and that's not something to wait out. If your furnace is old and you're heating parts of the year, October through May here, on a unit that needs constant attention, replacement usually costs less over time than another season of repairs. A contractor can look at its age and condition and tell you whether repair still makes sense.
- Is a high-efficiency furnace worth it?
- It depends on how much you run your furnace and what you're replacing. Any non-weatherized gas furnace built since November 2015 already has to reach 80 percent AFUE, so the real choice is between that and a high-efficiency model rated higher. Winters here average 21°F and homes need heat for 8 months, October through May, which means your furnace runs more than one in a milder climate. That's the condition where a higher efficiency rating pays off over the furnace's life. A contractor can walk you through the models and what each one means for your house.
