Nine months of heat, seven degrees at night
Your furnace in Kandiyohi County works most of the year. Heat runs from September through May, and on the coldest nights it's cycling on and off for hours at a time, fighting to keep up as the temperature outside sits around 7°F. Every one of those cycles depends on the igniter lighting the burner. Enough cold nights and enough cycles, and that igniter is what fails, usually right when you need heat the most.
Summer asks less of the system here, just June through August, with afternoons around 80°F. But storms are part of the picture too. Kandiyohi County has seen 30 winter storms and 40 damaging wind events over the past ten years, and outages follow. Across Minnesota, 13% of households lost power for a full day or more in 2024. When the power drops and comes back, most furnaces and air conditioners restart on their own. If yours doesn't, that's worth a call.

A new furnace and air conditioner would cut about $140 a year off heating and cooling for a typical Kandiyohi County home.

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.
There is no state license or registration for HVAC contractors in Minnesota. No test, no state file, nothing recorded with any state office before a contractor takes on this kind of work. Whatever standing a contractor has comes from the business itself, not from anything the state issued.
For a repair on a heating and cooling system, that means the state is not the thing standing behind the work. A bad connection on the gas side is the dangerous part of this job, and nothing in the state's rules names who checks that here.

- Why is my heat not working?
- Most often it comes down to power, gas, or airflow. Check that the thermostat is set to heat and the temperature is above room temperature, then check the breaker and the furnace switch, which looks like a regular light switch near the unit. If it has a standing pilot, see if the pilot light is out. Winter nights here average 7 degrees, so a furnace that will not fire needs attention fast, and if the basics check out and it still will not run, that points to something like the igniter or the flame sensor, which is a repair for a contractor.
- Why is my system running but not cooling the house?
- The system running but not cooling usually means the air is not actually cold, or it is cold but not moving through the house. Check the air filter first, since a clogged one chokes off airflow at the vents. Check the outdoor unit too, and clear away any grass clippings or debris stacked against it. If the filter is clean and the outdoor unit is clear but the air coming from the vents still is not cold, the refrigerant charge or the compressor likely needs a contractor to look at it.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to the right mode, heat or cool, and that the target temperature is actually past room temperature. Next check the breaker box for a tripped breaker, and check any power switch on or near the unit itself. Then look at the air filter and replace it if it is dirty, since a clogged filter can cause problems that look like bigger failures. If all of that checks out and the system still is not working right, a contractor will need to diagnose it further.
