Eight months of heat, and nights near 11 degrees
Winona homes need a working furnace from October through May. That is eight months out of the year the system has to be ready to run, not just on the coldest nights but on the ordinary ones too, since winter lows here average 11°F.
A furnace installed today has to meet a federal minimum of 80 percent AFUE if it burns gas, and most homes here do, with 55.4 percent heating with gas. Winter in this area also brings storms that knock out power, 30 of them over the last ten years along with 63 damaging wind events, so the furnace going in is one more thing worth asking about when the lights go out too.

Minnesota has no state license for HVAC contractors.
Minnesota does not test HVAC contractors, so there is no exam behind the name and no state license number to check. Nothing is filed with the state either way, so the protection here does not come from a credential.
For a furnace installation, the check that exists is local. In most cities and counties a furnace replacement needs a permit from the local building office, and an inspector looks at the work once it is done. That inspection is what catches a bad gas connection or a venting mistake, since Minnesota has no state license to hold a contractor to that standard. Gas heat is common here, with 55.4% of homes in Winona County running on it, so that inspection is doing real work on a lot of furnaces.

- What size furnace does my house need?
- There is no answer to this without looking at your house. A furnace that is too big will short cycle, heating quickly then shutting off before it warms the place evenly, and one that is too small will run constantly and still leave you cold on a night that hits 11°F. The right size comes from a load calculation, which weighs your square footage against your insulation, your windows, and how the house is laid out. A contractor doing your furnace installation will run that calculation rather than go by the size of the unit you have now, since that one may have been wrong too.
- How do I know it's time to replace my furnace?
- Watch for a furnace that struggles to keep up on the coldest nights, cycles on and off more than it used to, or needs a repair call every winter. Winona homes lean on their furnace 8 months of the year, October through May, so an aging unit here gets worked harder than one in a place with a shorter winter. If yours is getting old and the repairs are becoming a pattern, a contractor can tell you whether the next fix is worth it or whether you are better off replacing it before it fails on a night near 11°F.
- Is a high-efficiency furnace worth it?
- It depends on how much heat your house actually calls for, and in Winona that is a lot. With winter running October through May and average lows near 11°F, a furnace here works harder and longer each year than one in a milder place. Every furnace made since November 2015 already has to hit at least 80 percent AFUE, so the real question is whether stepping up to a higher-efficiency model makes sense for your house and your furnace installation. A contractor can walk you through the options and what each one means for your specific home.
