Nine months of heat, three of cooling
Your furnace in Red Wing runs from September through May. On winter nights that average 10°F, it cycles on and off for hours at a stretch, and every start puts wear on the igniter. When that part finally gives out, the burner won't light, and the house goes cold fast at that temperature.
Summer asks less of the system, just three months of cooling with afternoons around 79°F. Goodhue County has seen 35 winter storms and 52 damaging wind events over the past ten years, and most furnaces and air conditioners come back on by themselves once the power returns. If yours doesn't, that's worth a call before you assume the system itself has failed.

A new furnace and air conditioner would cut about $140 a year off heating and cooling for a typical Goodhue County home.
Estimates for a typical Goodhue County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Minnesota fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
Minnesota has no state license for HVAC contractors.
Minnesota keeps no state record of who does this work. There is no license to check and no registration on file, so the state itself has nothing to tell you about a contractor before they touch your furnace or your coil.
That means whatever protection you have on this job does not come from the state. It comes from whoever is standing behind the work, the contractor's own history and how they answer for it, since Minnesota has not put a license or a state record between you and them.

- Why is my heat not working?
- Most often the thermostat, the igniter, or a safety switch is stopping the furnace from starting or staying on. If the furnace won't fire at all, check that the thermostat is set to heat and above room temperature, and that the switch on the furnace itself is on. A furnace that starts then shuts off partway through is usually tripping a safety switch, often because a clogged filter is starving it of airflow. At 10°F on a winter night here, a furnace that keeps failing needs a contractor before the cold does real damage to pipes in the house.
- Why is my system running but not cooling the house?
- If air is coming out but it is not cold, the problem is usually low refrigerant, a frozen coil, or a blocked filter. Check the filter first. A filter clogged enough to choke airflow will ice up the coil behind it, and once that happens the system blows warm air even though it is running. If the filter is clean and the air still is not cold, the refrigerant charge is likely low, and that is a repair for a contractor, not something to top off yourself. Running a system with a frozen coil for long can damage the compressor, so it is worth shutting it off and letting it thaw before anyone works on it.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to heat or cool as needed and that the batteries are not dead. Next, check the filter. A dirty filter is behind a lot of the calls that turn out to need no repair at all, and it is the one thing in the system you can look at yourself. Check that the furnace or outdoor unit has power, since a tripped breaker or a switch bumped off will stop either one cold. If the furnace uses a standing pilot, see whether it is lit. If none of that explains it, a contractor can diagnose the rest.
