Nine months of heat, three of cooling, in a place that swings hard
A new system in Lake County has to work almost year round. Homes here need heat from September through May, nine months out of twelve, and winter nights average 9°F from December through February. That kind of cold means long, steady burner or compressor cycles just to hold a room at temperature, and it means a furnace sized to keep up when the outdoor air is nowhere near mild.
Summer is short here, just June through August, but afternoons still average 80°F, so the same system has to switch gears and cool the house well for those three months. Just over half of homes in the area heat with gas, and any new furnace installed has to meet the federal minimum efficiency rating. On top of the temperature swings, the area has seen 27 winter storms and 48 damaging wind events over the past ten years, so the equipment and its outdoor unit need to be installed to hold up through rough weather, not just calm days.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
That means there is no statewide record of who is allowed to install a heating and cooling system. Whatever protection exists depends on where the house sits, since South Dakota leaves the rule to each city and town. Some places set their own license or registration for contractors before they can take the job, others have no such rule at all, and no state office keeps a record either way.
For this job, what applies in most places is the permit. Installing a new furnace, air conditioner or heat pump usually requires a permit from the local building office, and an inspection once the work is done. That inspection checks that the installation itself was done correctly, not whether the contractor holds any license. In a town with no local licensing rule, the permit and inspection are what stand between the homeowner and a bad job.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is getting old and needs a repair, that is usually a good time to ask about replacement instead. Watch for the signs too. A furnace that short cycles, an air conditioner that cannot keep up on an 80°F afternoon, or a system that needs a repair every season are all telling you the same thing. Here, with heat running from September through May, a furnace that fails in the cold months is a much bigger problem than one that fails in summer, so it pays to have it looked at before the cold sets in rather than during a winter storm.
- Should I replace my furnace and air conditioner at the same time?
- If they are close in age, yes, and there is 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. Replacing both also means one round of ductwork checks and one inspection instead of two separate jobs down the line. If one of the two still has several years left in it, a contractor can tell you whether it is worth waiting or worth doing now.
- What happens during an HVAC installation?
- A contractor first sizes the new furnace or air conditioner to the house, since one that is too big or too small will not heat or cool it evenly. The old equipment comes out, the new unit goes in, and it gets connected to the existing ductwork, gas line or electrical circuit, and the vent or refrigerant lines it needs. Most cities and counties here require a permit for this work and an inspection once it is done, so the contractor will typically handle that as part of the job. Once it is running, they will check airflow and startup to make sure the system is working the way it should before they leave.
