Eight months of heat in Michigan City
Your furnace has to work from October through May here, with winter nights averaging 20°F. That is most of the year spent leaning on a system that has to start reliably in the cold and keep running through it. Most homes in this area heat with gas, so when the power goes out, a furnace with a standing pilot will keep running, but one that needs electricity to ignite will not, and outages are not rare here. Laporte County has seen 60 damaging wind events and 4 winter storms over the past ten years.
Any non-weatherized gas furnace built since November 2015 has to reach at least 80 percent AFUE by federal rule, so that is the floor, not a feature to look for. What matters more for a house here is a furnace built to run this long, this cold, for this many months without the power behind it.

In Indiana, HVAC licensing for homes is left to the counties and cities.
LaPorte County sets its own rule on who can do this work, since Indiana leaves the question to local government. That means there is no state license number to check and no state board keeping a file on the contractor. Whatever oversight exists here comes from the county or city office that covers your address, not from Indianapolis.
For a furnace install, the protection you have is the permit and inspection most local building offices require when a furnace gets replaced. That inspection is what catches a bad gas connection, which is the part of this job that can actually hurt someone. Most homes in LaPorte County heat with gas, so that check matters here more than in a county running mostly on electric heat.

- What size furnace does my house need?
- The right size depends on your square footage, your insulation, your ceiling height, and how many windows you have, so no one can give you a number without looking at the house. A contractor will run a load calculation room by room rather than go off square footage alone. This matters here since your furnace has to hold its own from October through May, and one that's sized wrong will either short-cycle or struggle to keep up on the 20°F nights.
- How do I know it's time to replace my furnace?
- Watch for uneven heat between rooms, a furnace that runs longer than it used to, or a rise in your gas bill with no other explanation. If it's needing repairs more often, that's usually a sign the next one is coming regardless of what gets fixed this time. If yours is a non-weatherized gas furnace built on or after November 19, 2015, it's required to run at 80 percent AFUE or higher, so an older unit may be running well below that every one of the 8 months a year you're heating this house.
- Is a high-efficiency furnace worth it?
- It depends on how many months your furnace runs and what you're replacing. Here, heat is on from October through May, eight months a year, so a furnace's efficiency rating matters more than it would somewhere that only heats for a few weeks. A contractor can walk you through the difference between a high-efficiency model and your current unit's AFUE rating to see whether the upgrade fits your house.
