Eight months of Vermillion winter wears a furnace down
Your furnace runs from October through May here, eight months of the year. On winter nights averaging 13°F, it can't take long breaks. It fires, holds the house at temperature, shuts off, and fires again, over and over through the night.
Each cycle puts a load on the igniter and the parts that get the burner going. Over enough winters that wear catches up, and the furnace either takes longer to light or stops lighting at all. With 32 winter storms and 40 damaging wind events recorded here over the past ten years, the day it quits is often the day you need it most.

A new furnace would cut about $80 a year off heating for a typical Clay County home.
Estimates for a typical Clay County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, South Dakota fuel prices and NOAA climate normals. Your home will differ.
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.
In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota does not license HVAC contractors at the state level. Whatever rule applies to a furnace repair in Clay County comes from the city or town where the house sits, not from the state. There is no statewide record of who has tested to work on a furnace here, the way there would be in a state that licenses.
That puts the weight on the gas connection itself, since that is the dangerous part of the job. Almost half the homes in Clay County heat with gas, and a furnace repair on one of those homes means working on a fuel line that has to be sealed correctly. Whether anyone inspects that connection depends on the town, since South Dakota leaves the question to cities and towns rather than answering it itself.

- Why won't my furnace turn on?
- Most of the time it's the thermostat not calling for heat, a tripped breaker, or the switch on the furnace itself gotten bumped off. Check the thermostat is set below room temperature and has power first. If those look fine, the igniter may have failed or a safety switch has shut the furnace down, and that calls for a contractor to check it out. With winter lows here averaging 13°F, it's worth getting it looked at the same day rather than waiting.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the furnace may be running the blower without the burners lighting, which points to an ignition problem or a safety switch cutting the burners off. It can also just be the furnace starting a cycle, since the blower sometimes runs a few seconds before the air warms up. If cold air keeps blowing the whole cycle, have a contractor check the igniter and the flame sensor.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit is usually the thermocouple, the part that senses the flame and keeps gas flowing to it. When it wears out or sits out of position, it reads the pilot as out even when it's lit, and shuts the gas off. A draft blowing across the pilot or a dirty pilot orifice can do the same thing. A contractor can tell which one it is and replace the part if needed.
