Nine months of heat, and nights that hit 6 below zero
Your furnace is the machine keeping the house livable from September through May. On the nights that average 6°F, it runs long and it runs often, and every cycle puts a load on the igniter and the blower motor. Those are the parts that tend to fail first, usually on the coldest night of the year, which is exactly when you need them not to.
Summer asks less of the system here. Afternoons average 81°F for two months, so the air conditioner isn't working as hard as the furnace does, but a coil or a capacitor that was already weak can still give out in that stretch. Add in the wind and winter storms this area sees most years, and a power blink is often what finally shows a problem that was building for a while.

A new furnace and air conditioner would cut about $110 a year off heating and cooling for a typical Morton County home.
Estimates for a typical Morton County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, North Dakota 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.
North Dakota requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to each job. It means the state has tested the contractor and keeps a record of them, not that this particular repair was checked or approved.
Work under $4,000 does not need a licensed contractor in North Dakota. This is a repair to a heating and cooling system, so if the job runs above that line, the contractor doing the work should hold the state license.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace. If the display is blank, check the breaker and any switch that looks like a light switch near the unit, since that shuts the furnace off for service. If it has power but the burners won't light, the igniter or the flame sensor is a common cause, and a furnace won't run without either one working. At 6 degrees on a winter night here, a furnace that won't fire is worth calling in fast.
- Why is my system running but not cooling the house?
- The fan running without cool air usually points to the outdoor unit, not the indoor one. A coil covered in ice, a dirty outdoor coil, or a refrigerant leak can all leave you with air moving but not cooling. Check that the outdoor unit isn't blocked by grass, leaves, or ice, and that the air filter isn't so dirty it's choking airflow. If both look fine, the problem is inside the system and needs a contractor to find it.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries, the breaker, and the air filter first. A dirty filter can cause a furnace to overheat and shut off, or make an air conditioner struggle to cool. Look for a shut-off switch near the furnace or outdoor unit that may have been bumped or turned off. If the outdoor unit is covered in ice or debris, clearing it may solve the problem on its own. Past that, a licensed contractor will need to diagnose it, and price the repair once they see what the house needs.
