Nine months of heat, nights near zero, and wind that doesn't let up
Your furnace works from September through May here. On the coldest nights it drops to 9°F, and the burner is cycling on and off most of the night to hold the house steady. That is a lot of starts on the igniter over a winter, and a lot of hours on the blower motor. When the igniter finally gives out, the furnace won't light at all.
Summer is short, just June through August, but afternoons reach 83°F and the AC has to work hard in that window. Beadle County has seen 104 damaging wind events over the past ten years, and wind like that can knock an outdoor unit's fan out of balance or drive debris into the coil. Add 23 winter storms in that same stretch, with the power flickering or cutting out, and you've got a system that gets asked to restart cold more often than most.

A new furnace and air conditioner would cut about $110 a year off heating and cooling for a typical Beadle 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.
In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota has no state license for HVAC contractors. The rule is left to cities and towns, so whether this job needs a local license depends on where the house sits, and there is no statewide record to check a contractor against.
For a heating and cooling repair, the part that matters most is any gas connection made or disturbed during the work. Whether that gets checked here depends on the same thing, the rule where the house is. There is no state inspection standing behind it either way.

- Why is my heat not working?
- Most often it's the igniter or a flame sensor that has failed, especially if the furnace runs a moment then shuts off. Check that the thermostat is set to heat and the temperature is above room temperature, and check that the filter isn't clogged, since a blocked filter can cause the furnace to overheat and shut down. If the breaker has tripped or a fuse has blown, that points to an electrical problem rather than the furnace itself. With winter nights here averaging 9°F, a furnace that won't stay lit needs attention fast, so a contractor should look at it the same day if you can manage it.
- Why is my system running but not cooling the house?
- If the blower is running but the air isn't cold, the most common cause is a dirty air filter restricting airflow across the coil, or a coil that's frozen over. A frozen coil needs the system shut off to thaw before anyone can diagnose it further, since running it iced up can damage the compressor. Low refrigerant from a leak is another common cause, and that's not something to add on your own. It's a job for a licensed contractor to find and seal the leak first.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set to the right mode and the temperature calls for what you want, and check the batteries if it has a screen that's dim or blank. Next, check the filter and replace it if it's visibly dirty, since a clogged filter causes both heating and cooling problems. Check the breaker panel for a tripped breaker, and if you have a gas furnace, make sure the gas valve is open. If none of that explains it, a licensed contractor will need to diagnose it. Whether that contractor needs a city license depends on where the house is, since South Dakota leaves HVAC licensing to individual cities and towns.
