A new system here works 11 months a year
Winter nights in Hennepin County average 10°F from December through February, and homes need heat from October through May, 8 months in all. Summer is shorter and milder by comparison, with afternoons averaging 80°F and cooling needed June through August. Add it up and there is only one month when the system isn't doing one job or the other.
A furnace or air conditioner installed here has to be sized for both ends of that range, the deep cold and the summer heat, not just whichever one is on your mind right now. Whatever goes in has to meet the federal minimum efficiency rating in place at installation. Minnesota also saw 13% of households lose power for 24 hours or more in 2024, and Hennepin County has logged 33 winter storms and 142 damaging wind events over the past ten years, so it is worth asking your contractor how the system you choose handles a power interruption on a cold night.

Minnesota has no state license for HVAC contractors.
There is no state agency behind the contractor doing this job, no exam and no state file to check. Anyone can start an HVAC business here, so the state is not the one standing between you and a bad install.
In most cities and counties, including here in Hennepin County, putting in a furnace and air conditioner needs a permit from the local building office, and an inspector checks the work once it's done. That inspection, not a license, is the check this job gets.

- When should I replace my HVAC system?
- Replace it when repairs stop making sense or the system can no longer keep up with your house. If a repair estimate is getting close to what a new system costs, or the same part keeps failing, replacement is usually the better move. A furnace that struggles or quits also matters more here, since homes need heat from October through May, eight months of the year. A contractor can look at the age and condition of your equipment and tell you honestly whether it's worth fixing again.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, it usually makes sense to do both together. A furnace and air conditioner installed at the same time are matched to work as one system, and doing the work in a single visit means one inspection instead of two. If your air conditioner is still working fine and only the furnace failed, a contractor can replace the furnace alone and connect it to the existing coil and condenser. What matters most is that the two pieces of equipment are matched to each other, and a contractor checks that either way.
- What happens during an HVAC installation?
- The contractor removes the old furnace, air conditioner, or both, then sets the new equipment in place and connects it to your ductwork, gas line, electrical, and refrigerant lines. For a furnace, that includes venting it correctly and testing the gas connection and igniter. For an air conditioner, it means connecting the outdoor unit to the indoor coil and checking the refrigerant charge. Minnesota has no state license for HVAC contractors, but most cities and counties here require a permit for this work and an inspection once it's done, which is what confirms the system was installed to code.
