Nine months of heat, four below zero, and not much room to spare
Your furnace in Otter Tail County works from September through May. On the coldest nights, when the temperature outside sits around 4°F, it runs long and it runs often, and every cycle puts wear on the igniter and the heat exchanger. When one of those fails on a night that cold, you feel it fast.
Summer asks less of the system here, just July and August, with afternoons around 78°F. But this county sees real weather. Ten years of records show 88 winter storms and 157 damaging wind events, and across Minnesota last year, 13% of households lost power for a full day or more. A furnace that loses power and comes back on usually restarts fine, but a storm that knocks out a part while it's running is a different problem, and it tends to show up as a system that won't respond when the weather turns again.

A new furnace and air conditioner would cut about $150 a year off heating and cooling for a typical Otter Tail County home.
Estimates for a typical Otter Tail 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 heating and cooling work. There is no license and no registration to check, nothing filed with the state that says a contractor was tested or vetted before taking your call. In a state that licenses this trade, that license is the thing you'd be relying on. Here that piece does not exist.
For a repair like this, the protection people usually point to in a licensed state is not available here. Gas repair matters because a bad connection is the dangerous part of the job, and in Minnesota there is no state license standing behind that work. Whatever confidence you have in the contractor doing this repair has to come from something other than a state credential, because the state has not created one.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and the set temperature is above room temperature, since a bumped switch or dead battery will stop a furnace before it ever starts. Check the breaker and the switch on the furnace itself, which looks like a light switch mounted on or near the unit. If those are fine, look at the filter. A filter clogged with dust chokes off airflow and can cause the furnace to shut itself down before it overheats. At 4°F outside, a furnace that will not run needs attention fast, so if none of this brings it back a contractor should look at it the same day.
- Why is my system running but not cooling the house?
- The most common cause is a dirty filter cutting off airflow across the indoor coil. When that happens the coil can ice over, and once it does, the air coming out of your vents turns warm even though the system is running. Check the filter first and replace it if it is gray or clogged. If the filter is clean and the air still is not cold, the system may be low on refrigerant from a leak, which is not something to add on your own since it means there is a leak somewhere in the line that needs to be found and sealed. A contractor will need to check the charge and find the leak before adding anything back.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it is set correctly, the batteries are good, and it is actually calling for heat or cooling. Check the breaker for the furnace or outdoor unit, and check the furnace switch, since either one being off will stop the system cold. Look at the filter next. A dirty filter is behind a lot of the calls people make for a system that will not heat or cool right, and it is the one thing you can fix yourself in a few minutes. If your outdoor unit is buried in snow or storm debris, clear it so air can move through it. If you have checked all of this and the system still is not working, tell the contractor what you found. It will help them get to the actual problem faster.
