Eight months of Lincoln County cold adds up
Your furnace runs from October through May here, and on winter nights that average 12°F it is cycling on and off most of the night to keep up. Every one of those cycles puts a load on the igniter and the burner, and after enough winters one of them quits. Most homes here run on gas, so it is the igniter and the flame sensor that tend to wear out first, not a motor or a belt.
Lincoln County has also seen 34 winter storms and 77 damaging wind events over the past ten years. Wind that strong can knock a vent pipe loose or drive cold air into the cabinet, and a furnace that was running fine can start short cycling or blowing cool air the same night.

A new furnace would cut about $80 a year off heating for a typical Lincoln County home.
Estimates for a typical Lincoln 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 itself. Whatever rule applies to a furnace repair in Lincoln County comes from the city or town where the house sits, not from the state. There is no statewide test or record to check against. What exists, if anything, is a local matter tied to the address.
A gas furnace has one part of the job that matters most. That is the connection that feeds it gas. A loose or bad fitting is what makes a furnace repair dangerous, not the rest of the work. The state has not set a rule for who checks that connection, so whatever oversight exists here comes from the city or town, not from South Dakota. In Lincoln County, 66% of homes heat with gas, so that connection is the thing worth getting right on this repair.

- Why won't my furnace turn on?
- Most of the time it's the thermostat not calling for heat, a tripped breaker, or a safety switch that's stopped the furnace from starting. Check that the thermostat is set below room temperature and has power, then check the breaker panel. Furnaces also have a switch that looks like a light switch near the unit, sometimes it gets bumped off. If power and settings check out, the igniter or a safety sensor inside the furnace may have failed, and that's a job for a contractor to diagnose.
- Why is my furnace blowing cold air?
- A furnace blowing cold air is usually still in its startup cycle, warming up before the blower kicks in with heated air. If the air stays cold, check the air filter first. A clogged filter chokes airflow and can cause the furnace to shut down its burner while the blower keeps running. If the filter is clean and the air still isn't heating, the igniter or gas valve may not be working, and a contractor will need to check it. With winter lows here averaging 12°F, a furnace that can't hold a heat cycle needs attention quickly.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit usually points to a failing thermocouple, the small sensor that tells the gas valve the flame is burning. When it wears out, it shuts the gas off even though the pilot is lit, or fails to sense the flame at all. A draft blowing out the pilot or a dirty pilot orifice can also be the cause. Since 66% of homes in Lincoln County heat with gas, this is a common call, and a contractor can test the thermocouple and replace it if needed.
