Nine months of heat, two months of cooling, little time off
Your furnace is the machine doing most of the work in Grand Forks County. It runs from September through May, and on nights that average 2°F it cycles on and off for hours to hold the temperature. Every start puts a load on the igniter and the blower motor, and that is where a furnace tends to fail first after years of this.
Summer asks less of the system, just July and August, but afternoons near 79°F still put real load on the air conditioner's compressor on the days it runs. The county has seen 81 winter storms and 188 damaging wind events over the past ten years, and statewide, 7% of households went at least 24 hours without power in 2024. A furnace that will not restart cleanly after the power drops is not a small thing here.

North Dakota requires HVAC contractors to hold a state license.
The state licenses the contractor, not the job, so what's on record is the business itself, tested and registered with the Secretary of State. Work under $4,000 falls outside that requirement, which means a small repair can legally be done without a licensed contractor.
A repair on a heating and cooling system is the kind of job where that threshold matters, since the cost of the license is what tells you a contractor was tested and is on record with the state. Gas connections are the part worth taking seriously, since a bad joint is what makes the repair dangerous rather than just incomplete.

- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat and the temperature is above room temperature, and check the batteries if it uses them. If the thermostat looks right, check the breaker for the furnace or air handler, since a tripped one will stop the system cold. A furnace that won't fire can also be sitting on a clogged filter or a safety switch that shut it down. At 2 below zero on a winter night, a heat outage becomes urgent fast, so if the basics check out and it still won't run, get a contractor out before the house cools further.
- Why is my system running but not cooling the house?
- The blower running without cool air usually means the outdoor unit isn't doing its job. Check the outdoor unit for anything blocking it, leaves, grass clippings, or ice on the coil. Check the filter too, since a dirty one starves the coil of airflow and can ice it over even when it's warm out. If the coil has ice on it, turn the system to fan only and let it thaw before calling, so a contractor can actually see what's wrong underneath.
- What can I check before calling for HVAC repair?
- Check the thermostat settings first, mode, temperature, and batteries. Check the breaker or fuse for the system, since a tripped breaker looks like a dead system but isn't. Check the filter and swap it if it's dirty, since a clogged filter causes both weak heat and weak cooling. For a furnace, check that the switch on or near the unit, the one that looks like a light switch, is on. If everything checks out and the system still isn't working, a contractor will need to look at it directly and price the repair once they know what's wrong.
