Eleven months of work a year for one system
Your furnace runs September through May in Watford City, and on the nights that drop to 7°F it cycles on and off for hours at a stretch. Each start puts a load on the igniter, and after enough winters like that, it quits, usually on the coldest night rather than a mild one.
Summer is short here, just July and August, with afternoons near 81°F, so the air conditioner sits idle most of the year and then has to start up cold when the heat arrives. That is when a weak capacitor shows itself. 60.1% of homes here heat with electricity, and that power has to stay on for the furnace to run at all. Mckenzie County has seen 16 winter storms and 79 damaging wind events over the past ten years, and in North Dakota, 7% of households lost power for at least 24 hours in 2024.

North Dakota requires HVAC contractors to hold a state license.
North Dakota tests and records HVAC contractors through the Secretary of State, and that license belongs to the contractor, not to any single job. It tells you the state has checked this contractor before, not that it is checking this repair. Work under $4,000 falls outside that requirement, so a smaller repair job can be done without a licensed contractor.
For a heating and cooling repair, whether the license applies at all comes down to the cost of the job. Above $4,000, the contractor doing the work is required to hold that state license. Below it, the state does not require one, and the license is the only state-level check this job has.

- Why is my heat not working?
- Start with the thermostat and the breaker before anything else. If the thermostat screen is blank or won't respond, check the breaker panel and any switch that looks like a light switch near the furnace, since that shuts it off too. A furnace that won't start at all is often the igniter or the flame sensor, and a furnace that starts then shuts off partway through is usually the flame sensor reading dirty. At 7°F on a winter night here, a furnace that's stopped needs attention fast, since the house loses heat quickly at that temperature.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and when that happens the coil can ice up and stop cooling the air even though the blower is still running. If the filter is clean, check that the outdoor unit isn't blocked by leaves or grass clippings, since it needs open airflow to release the heat it's pulling out of the house. If the air coming from the vents is barely cool or not moving much, that points to something a contractor needs to look at directly.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries and settings, the breaker for the furnace or air conditioner, and the air filter. A dead thermostat battery can look exactly like a dead system. A tripped breaker will stop the unit from running at all, and if it trips again right after you reset it, leave it off and mention that when you call. A dirty filter is the most common reason a system runs weak, so swap it if it's been a few months. Beyond that, a contractor will need to look at the system directly and price the repair for your house.
