Nine months of heat, and nights near zero
Grafton needs a working furnace from September through May. That is 9 months of the year, and the coldest stretch runs winter nights that average 1°F. A furnace built for that has to cycle on and off many times a night just to hold the house steady, and every one of those starts puts wear on the igniter and the flame sensor.
Walsh County also sees its share of winter storms, 102 of them in the last ten years along with 71 damaging wind events. Storms like that knock out power, and across North Dakota, 7% of households lost power for at least 24 hours in 2024. A furnace with no electricity will not light no matter what shape it is in, and a system already worn from a hard winter is the one most likely to fail when the power comes back on.

A new furnace would cut about $120 a year off heating for a typical Walsh County home.

Repair makes sense when one part has failed and the heat exchanger is sound.
Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.
North Dakota requires HVAC contractors to hold a state license.
The license comes from the Secretary of State, and it covers the contractor, not the job. The state tested this contractor and keeps a record of them, and that record follows them from house to house. It does not mean an inspector checks each repair. In North Dakota, work under $4,000 does not need a licensed contractor, so a furnace repair at that size can fall outside the rule the headline states.
When the job is repairing a furnace, the license does not cover what makes the job dangerous. That comes down to the gas connection, and the facts here do not name anyone who inspects that connection on a repair this size. In Walsh County, 40.4% of homes heat with gas.

- Why won't my furnace turn on?
- Most often it's the thermostat, the power supply, or a safety switch stopping it before it starts. Check that the thermostat is set below room temperature and has working batteries. Check the switch on the furnace itself, the one that looks like a light switch, and make sure it's on. If the filter hasn't been changed in a while, a clogged one can trip a safety switch and shut the whole system down. Past that, it's a job for a licensed contractor to trace, since North Dakota requires one to work on it.
- Why is my furnace blowing cold air?
- If the air feels cold but the furnace is running, it may just be starting a cycle, since the blower can kick on before the burners have warmed up. If that lasts more than a few minutes, the igniter or a flame sensor may be failing to light the burners at all, so the blower runs with nothing to heat. A clogged filter can also starve the system of airflow and throw things off. With nights averaging 1°F here through the winter, this isn't something to leave alone. A licensed contractor can find the actual cause.
- Why won't my furnace pilot light stay lit?
- This usually comes down to the thermocouple, the small part that senses the pilot flame and keeps gas flowing to it. When it wears out, it can't tell the flame is lit, so the gas valve shuts off and the pilot goes out. A draft blowing across the pilot or a dirty pilot orifice can cause the same thing. A standing pilot doesn't need power to stay lit, so this isn't a power issue. It's a gas appliance, so have a licensed contractor replace the part rather than trying to keep relighting it.
