Nine months of heat, one month of cooling
Winter nights in Itasca County average 1°F from December through February. Homes here need heat from September through May, nine months of the year. That is a long stretch for a furnace to carry, and it has to hold up night after night at temperatures that low.
Summer asks much less. Afternoons average 76°F, and July is the only month cooling is needed. A new system still has to handle both ends of that, the long cold season and the short mild one. Power is worth planning around too. Minnesota saw 13% of households lose power for 24 hours or more in 2024, and the county has logged 59 winter storms and 108 damaging wind events over the past ten years.

Minnesota has no state license for HVAC contractors.
There is no state license or registration behind the contractor who does this job. No test, no state record, nothing filed with Minnesota to check against. What stands between you and a bad install is not a credential, it is the permit process in your own city or county.
An installation like this, a furnace and air conditioner or heat pump going in together, needs a permit from the local building office in most cities and counties, and an inspection once the work is done. That inspection is what checks the gas connections, the wiring, the venting, the things that make an install safe rather than just finished. Where that permit and inspection apply, they are the outside check this job gets.

- When should I replace my HVAC system?
- Look at how it's been running, not just whether it still turns on. If you're calling for repair every year, or one part has already been replaced once, the next failure is the one to plan for instead of react to. Homes here need heat from September through May, so a furnace that quits in that stretch isn't a small inconvenience. Waiting until it fails leaves you choosing a system in a hurry instead of choosing the right one.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes. A furnace and air conditioner installed together are matched to work as one system, and pairing a new one with an old one can mean the new unit never runs at its rated efficiency. It also means avoiding a second installation, and a second round of permit and inspection, a few years later when the other one fails. If one unit is much newer than the other, replacing just the older one still makes sense, and a contractor can tell you whether the two you have are compatible enough to leave one in place.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner, or both, and sets the new equipment in place, connecting it to your ductwork, gas line or electrical circuit, and the refrigerant lines for the outdoor unit. They check the ducts for leaks or sizing problems while they're in there, since a new system connected to bad ductwork won't perform the way it should. Once it's running, they test it, set the thermostat, and walk you through anything you need to know. Replacing a furnace or air conditioner needs a permit from the local building office, and the work gets inspected once it's done.
