A system built for eleven months of work
Your new furnace and air conditioner will run almost all year here. Homes in Lincoln County need heat or cooling 11 months out of 12, with only a short break in between. Winter nights average 12°F from December through February, cold enough that a furnace sized wrong will run long and often. Summer afternoons reach 82°F, so the air conditioner has its own season to answer for, short as it is.
Most homes here heat with gas, and whatever you install has to handle both ends of that range without strain. The county has seen 34 winter storms and 77 damaging wind events over the last ten years, so the system also has to start reliably after the power drops and the temperature does too.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota has no state HVAC license. Whether this installer needs a local license depends on the city or town, since that rule is set town by town rather than by the state.
For a job like this, installing a furnace and air conditioner or heat pump, most cities and counties require a permit before the work starts and an inspection once it is finished. That permit and inspection are the check that exists here, not a license.

- When should I replace my HVAC system?
- Replace it when repairs are getting frequent, when the unit is old, or when it can no longer keep up on the coldest or hottest days. Once a system is old enough that a contractor is quoting a major repair, that's usually the point to weigh replacement instead of fixing it again. Homes here run the furnace from October through May, so a system on its way out gets tested hard most of the year. A breakdown on a night averaging 12°F is a real risk if the furnace is already struggling.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often the better move, but it depends on the condition of each one. A furnace and air conditioner installed at different times can still work fine side by side as long as both are sized and matched correctly. Where it matters more is when one has already failed and the other is close behind. A contractor looking at the age and condition of both can tell you whether pairing the work makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner or heat pump and sets the new equipment in its place, connecting it to the ductwork, gas or electric lines, and the condensate or refrigerant lines it needs to run. Once it's in, they test it, check the airflow, and confirm it's firing or cooling correctly. In most cities and counties around Harrisburg, this work needs a permit from the local building office and an inspection when it's done, since South Dakota leaves HVAC licensing to the cities and towns rather than the state. Ask the contractor whether they're pulling the permit or whether that falls to you.
