Eight months of heat, and nights that drop to 10°F
Shakopee homes need heat from October through May. That is eight months of the year the furnace has to work, and on winter nights it is holding the house against an average low of 10°F. A furnace sized and installed for this has to carry that load night after night, not just get through a cold snap.
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. That is the floor, not a target. Scott County has also seen 35 winter storms and 53 damaging wind events over the past ten years, and enough Minnesota households lost power for a day or longer in 2024 that it is worth asking how a new furnace starts back up once the power does.

Minnesota has no state license for HVAC contractors.
Minnesota does not put any state paperwork behind an HVAC contractor's name, so there is no license number to check and no state record of who is qualified. Nothing is tested, nothing is filed. Whatever protection exists here comes from somewhere other than the state.
For a furnace installation in Scott County, the protection comes from the local building office. In most cities and counties, a furnace replacement needs a permit and an inspection once the work is done, and that inspection is where the gas connection and venting get checked. That matters because a bad connection is the dangerous part of the job. Most homes in Scott County heat with gas, so that inspection is doing the work a license would do in another state.

- What size furnace does my house need?
- It depends on your house, not just its square footage. A contractor works out the size by looking at how much heat your house loses, which comes from the insulation, the windows, the ceiling height, and how the place is laid out. A furnace that's too big will short cycle, turning on and off more than it should, and one that's too small will run constantly and still leave rooms cold. With winter lows around 10°F here, getting this number right matters more than in a milder place, so ask for a load calculation rather than a guess based on the old furnace.
- How do I know it's time to replace my furnace?
- Watch for repairs that keep coming back, rooms that won't hold an even temperature, and a heating bill that keeps climbing without a clear reason. Furnaces here run about 8 months a year, October through May, so the wear adds up faster than it would somewhere warmer. If yours is old enough that parts are getting hard to find, or if a technician has told you the heat exchanger is cracked, replacing it is the safer call. A furnace that's struggling shouldn't be leaned on through a Minnesota winter.
- Is a high-efficiency furnace worth it?
- Any furnace installed new today has to meet at least 80.0 percent AFUE, so you're not choosing between efficient and inefficient, you're choosing how much more efficient to go. Since 81.2% of homes in Scott County heat with gas and you're running the furnace 8 months out of the year, the fuel this thing burns adds up. A higher-efficiency model costs more to install but uses less gas doing the same job, so whether it pencils out depends on how long you plan to stay in the house and how the numbers compare for your specific furnace. A contractor can walk you through the options and price it for your house.
