Custer County asks a lot of a heating and cooling system
Nine months of heat, December through February nights averaging 15°F, and a furnace that has to hold its own against that cold night after night. Summer only asks for two months of cooling, with afternoons around 81°F, but that still means a system built for both jobs, not just one.
Only two months a year pass without either running. Ten years of storm records show 125 winter storms and 158 damaging wind events in the county, the kind of weather that a new system has to be installed to withstand, not just run in on a calm day.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota has no state HVAC license. The rule is left to cities and towns, so what applies to this job depends on whether Custer County or the nearest town has set its own licensing requirement. There is no state test or state record behind the contractor here, only whatever the local government chooses to require.
For an installation like this, the permit and inspection process is what stands in for a license. In most cities and counties, putting in a new furnace, air conditioner or heat pump requires a permit from the local building office, and the completed work gets inspected before it is signed off. That inspection is where a bad gas or electrical connection gets caught, since nothing at the state level checks it here.

- When should I replace my HVAC system?
- Replace it when repairs start happening every year, or when the system is old enough that another breakdown feels close. A furnace or air conditioner much past fifteen years is working harder than it should, and here that means nine months of heat and two months of cooling riding on equipment that's already tired. If a contractor is telling you a repair costs a large share of what a new system runs, that's usually the point where replacing makes more sense than fixing again.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, and there's a real reason for it. A furnace and air conditioner installed together are matched to work as one system, and pairing an old unit with a new one can mean the new one never runs at its rated efficiency. It also means one visit and one inspection instead of two separate jobs down the road. If one unit is much newer than the other, a contractor can tell you whether they're still a good match.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner or heat pump and sets the new one in place, then connects it to the ducts, the electrical, the gas line or refrigerant lines, and the thermostat. Once it's running, they check refrigerant charge, airflow and temperature rise to make sure the system is performing the way it's rated to. In most South Dakota cities and counties this work needs a permit from the local building office, plus an inspection when it's done, since HVAC licensing here is set by the city or town rather than the state.
