Ten months of heat, one month of cooling, and long stretches near zero
Rolette County asks for heat from September through June. Winter nights average 0°F from December through February, so the furnace holds a long, hard job for most of the year. It cycles on and off through nights that stay near zero, and every cycle puts wear on the igniter and the parts that get the burner going. When one of those parts finally gives out, the house goes cold fast at that temperature.
Most homes here heat with electricity, so a power outage means no heat at all, not just a lower setting. Storms are part of why that matters. The area has logged 33 winter storms and 34 damaging wind events over the past ten years, and statewide, 7 percent of households lost power for at least 24 hours in 2024. Summer is short, with afternoons averaging 76°F in July, so the air conditioner gets one real month of work before it sits idle again for most of the year.

North Dakota requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to a particular job. It tells you the state has processed and recorded that business, and it stays tied to them across the work they take on rather than being reissued each time.
For a heating and cooling repair, that license is what stands behind the person working on your system, as long as the job costs $4,000 or more. Under that amount, North Dakota does not require the contractor doing the work to be licensed.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and the temperature is set above room temperature, since a setting bumped by accident is the simplest cause. If that checks out, look at the filter. A filter clogged with dust chokes off airflow and can cause a furnace to shut itself down before it overheats. Check the breaker too, since a tripped breaker will stop a furnace cold with no warning. If none of that explains it, the igniter or the flame sensor may have failed, and that is a job for a contractor. With winter nights here averaging 0°F, a furnace that will not fire is not something to leave for later.
- Why is my system running but not cooling the house?
- If the blower runs but the air is not cold, the most common cause is a dirty filter or a frozen coil. A clogged filter starves the coil of airflow, ice builds up on it, and warm air just passes over the ice without losing any heat. Turn the system off and let it thaw for a few hours, then replace the filter and try again. If it freezes up again or the air was never cold to begin with, the refrigerant charge or the compressor may be the problem, and that needs a contractor to check with gauges.
- What can I check before calling for HVAC repair?
- Check the thermostat settings first, then the filter, since those two cause more no-heat and no-cool calls than anything else. Look at the breaker panel for a tripped breaker, and if you have a furnace, check that its switch, which looks like a light switch near the unit, is turned on. For a gas furnace, make sure the gas valve is open. If everything there looks right and the system still is not working, a contractor will need to look at it directly. Anything beyond these checks, like refrigerant levels or electrical faults inside the unit, is not something to test yourself.
