Step 1 of 3: Equipment
An unfinished basement featuring concrete block walls, exposed floor joists, a bare concrete floor, and a forced-air furnace with a large metal exhaust duct in the corner.

A new system has to cover nine months of heat and three of cooling

Winter nights here average 6°F from December through February. A new furnace has to cover that cold along with the milder days around it, since homes in Stearns County need heat from September through May. That's nine months of the year the heating side of the system is doing the real work.

Summer only asks for three months, June through August, with afternoons averaging 79°F. But the system runs on one or the other nearly all year, so whatever gets installed needs to be sized and set up right for both jobs, not just the one you're thinking about today.

Minnesota has no state license for HVAC contractors.

There is no state record of who is doing this work here, no test they had to pass and no license number to check. What protection exists comes from somewhere else.

For a job like this, that somewhere else is the local building office. In most cities and counties, installing a furnace, air conditioner or heat pump means pulling a permit, and the work gets inspected once it's done. That inspection is what stands between you and a bad hookup, not a license, because none exists to stand in for it.

When should I replace my HVAC system?
Replace it when repairs stop making sense, or when the furnace or air conditioner starts struggling to keep up. Watch for rising repair calls, uneven heating room to room, or a system that runs constantly without getting the house comfortable. Here, homes need heat or cooling all year, from September through May for heat and June through August for cooling, so a failing system does not get an easy season off. If yours is old and has not been checked recently, get it looked at before the next cold stretch rather than waiting for it to quit.
Should I replace my furnace and air conditioner at the same time?
If they are close in age, replacing them together often makes sense, but it depends on the condition of each one. A furnace and air conditioner installed at the same time tend to wear out around the same time too, so if one is failing the other may not be far behind. They also share parts of the system, like the blower and ductwork, so pairing new equipment with an old, mismatched unit does not always work as well as a matched set. A contractor can check both and tell you honestly whether one still has years left or whether doing the job once makes more sense.
What happens during an HVAC installation?
A contractor removes the old equipment, sets the new furnace and air conditioner or heat pump, and connects it to your ductwork, gas line or electrical, and condensate drain. They check that the ducts are sized right for the new equipment and run the system through a full cycle before calling the job done. In most places here, this work needs a permit from the local building office, with an inspection once it is finished. Minnesota has no state license for HVAC contractors, so ask directly about the permit and inspection if it is not already part of the plan.
