Nine months of heat, and nights near zero
Your furnace in Grafton runs September through May. That is most of the year, and on winter nights that average 1°F, it runs long and hard to keep up. The burner cycles on and off for hours at a stretch, and every cycle puts wear on the igniter and the flame sensor. When one of those fails on a night that cold, the house does not just get chilly, it gets dangerous fast.
Summer asks less of the system here. Afternoons average 78°F and the air conditioner only has July and August to earn its keep, so a unit that sits idle nine months can be slow to start when it finally gets the call. Add in the storms, 102 of them over the last ten years along with 71 damaging wind events, and the power going out on top of a system already under strain. Statewide, 7 percent of households lost power for a full day or more in 2024. When the power comes back, most furnaces and air conditioners restart on their own, but whatever knocked the power out may have knocked something else loose too.

A new furnace and air conditioner would cut about $130 a year off heating and cooling for a typical Walsh 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.
North Dakota requires HVAC contractors to hold a state license.
North Dakota issues this license through the Secretary of State, and it belongs to the contractor as a business, not to any single job. The state has checked that contractor once, up front, rather than reviewing each repair that comes after. Work under $4,000 does not need a licensed contractor at all, so North Dakota's own rule carves out smaller jobs from the requirement in the headline.
A heating and cooling repair can land on either side of that line depending on what the work involves. Where it falls above the threshold, the license is what stands behind the person doing the work. Where it falls below, North Dakota's rule does not require one, and the facts here do not say who checks a gas connection or a repair job priced under that line.

- Why is my heat not working?
- Most of the time it comes down to the thermostat, the igniter, or the power supply to the furnace. If the thermostat screen is blank, check the breaker before anything else. A furnace that clicks but never lights usually has a failing igniter or a flame sensor that needs cleaning. With winter nights here averaging 1°F, a furnace that is not heating is not something to wait out. A contractor can find out which part failed and fix it.
- Why is my system running but not cooling the house?
- If the fan runs but the air is not cold, check the air filter first. A clogged filter chokes airflow across the coil and the whole system struggles to cool. If the filter is clean and the air still is not cold, the refrigerant charge or the outdoor unit's coil may be the problem, and that calls for a licensed contractor. Summers here only run July and August with afternoons around 78°F, but a system that cannot cool on those days still needs the same fix.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to heat or cool as needed and that the batteries are not dead. Check the breaker panel for a tripped breaker, and look at the air filter since a dirty one can cause both heating and cooling problems. If the outdoor unit is covered in snow or debris, clear it. Past that, the equipment itself needs a licensed contractor to look at it. A contractor can diagnose what is wrong and price the repair for your house.
