Ten months of heat a year wears a furnace down fast
Rolla needs heat from September through June. That is ten months of the burner cycling on and off, and on the coldest nights, when the average low drops to zero, it runs almost nonstop to keep up. Every start puts load on the igniter and the switches that control the burner, and after that many cycles a season, those are the parts that fail first.
Most homes here heat with electricity, so when a winter storm knocks out power, the furnace stops with it. The area has seen 33 winter storms and 34 damaging wind events over the past ten years, and statewide, about 7 percent of households lost power for a full day or more in 2024. When the power comes back, some furnaces need a hand to get going again.

North Dakota requires HVAC contractors to hold a state license.
The license is held by the contractor as a business, not issued job by job, so it is the company's standing on record with the state rather than a paper pulled for your furnace repair. The Secretary of State keeps that record, which means the contractor was vetted before ever being on your street.
In North Dakota, work under $4,000 does not need a licensed contractor, so a small furnace repair can fall outside that requirement depending on the bill. A gas furnace still depends on a sound connection at the line and the burner, and that is the part worth getting right whether or not the job crosses that dollar line.

- Why won't my furnace turn on?
- The most common reason is a bad thermostat signal or a safety switch that has tripped. Check that the thermostat is set to heat and the temperature is above room temperature, and check that the furnace filter isn't so clogged it shut the blower down. If the switch on the furnace door isn't pushed in all the way, or a float switch nearby has tripped from standing water, the furnace won't start at all. A contractor can trace it to the actual part in an hour or so.
- Why is my furnace blowing cold air?
- Furnaces take a minute or two to warm up before the blower kicks on, so a short burst of cool air at startup is normal. If the air stays cold, the igniter or flame sensor may be failing, so the burners never light even though the blower keeps running. A cracked heat exchanger or a gas supply problem can also stop the burners while the fan runs on. Since this home needs heat most of the year, it's worth having a contractor check it before the next cold night.
- Why won't my furnace pilot light stay lit?
- A weak or dirty thermocouple is the usual cause. That's the small sensor the pilot flame touches, and if it's coated with soot or worn out, it tells the gas valve the flame is out even when it isn't, so the valve shuts the gas off. A draft blowing across the pilot, or a pilot orifice partly clogged, can do the same thing. A standing pilot doesn't run on electricity, so this isn't a power problem, it's the thermocouple or the gas valve itself that needs a look.
