Nine months of heat, three months of cooling, and storms in between
Your furnace in Moorhead runs from September through May. On winter nights that average 3°F, it cycles on and off for hours at a stretch to keep the house warm, and each cycle puts wear on the igniter and the blower motor. When one of those fails on a night that cold, you find out fast.
Summer asks less of the system, three months of afternoons averaging 80°F, but the air conditioner still has to start reliably every time it's called on. Clay County has logged 66 winter storms and 78 damaging wind events over the past ten years, and storms like that knock out power. Across Minnesota, 13% of households lost power for a day or more in 2024. Just over half the homes here heat with gas, and a gas furnace still needs electricity to run its blower and controls, so a storm that cuts power cuts your heat too.

A new furnace and air conditioner would cut about $150 a year off heating and cooling for a typical Clay 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.
Minnesota has no state license or registration for HVAC contractors, so there is no state record to check on the person coming to your house in Clay County. No board has tested this contractor, and no state agency has their business on file. Anyone can do this repair without answering to a state authority.
With no state license behind this job, the protection has to come from elsewhere. Gas repair is the dangerous part of the job, since a bad connection is what puts a home at risk. Minnesota has no state rule requiring a license for this work, so nothing at the state level stands between you and the person doing it.

- Why is my heat not working?
- Most often the thermostat, the igniter, or the flame sensor is the cause. If the furnace won't start at all, check that the thermostat is set to heat and above room temperature, and check the breaker. If it starts and then shuts off, the flame sensor is usually dirty and cannot tell the burner is lit, so the system cuts fuel as a safety step. At 3°F outside overnight, a furnace that keeps failing needs a contractor before the next cold night, since the house will not hold heat long once it stops running.
- Why is my system running but not cooling the house?
- The fan is moving air, but something is stopping that air from getting cold or getting through the house. A clogged filter is the most common cause. Air still comes out of the vents, but not enough of it, and the coil behind the filter can ice over from lack of airflow. Low refrigerant is another cause, and that only shows up as warm air, never as the system refusing to run. Check the filter first. If it is clean and the air still is not cold, that points to the refrigerant or the coil, and a contractor needs to look at 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, the batteries are good if it uses them, and the temperature is actually set past the room temperature. Next check the breaker box for a tripped breaker, and check that any furnace or AC power switch nearby is on. Then check the filter. A filter packed with dust chokes off airflow and can cause the system to run without heating or cooling the house, and in a furnace it can also trigger a safety shutoff. If those are all fine and the system still is not working, that points to something inside the unit, and a contractor will need to look at it.
