A new system here needs to handle nine months of heat and three of cooling
Winter nights in Moorhead average 3°F from December through February. A new furnace has to hold a house against that cold night after night, for a season that runs September through May. That's nine months of heat, three of cooling, so summer matters too. Afternoons average 80°F from June through August, and the system you install has to cover that stretch as well.
Moorhead has seen 66 winter storms and 78 damaging wind events over the past ten years, and outages happen. Across Minnesota, 13% of households lost power for 24 hours or more in 2024. Whatever you install, it's worth knowing how it responds when the power goes out and comes back, and whether it needs anything from you to restart.

Minnesota has no state license for HVAC contractors.
There is no state license or registration behind that work in Minnesota, and no state record of who is doing it. Anyone can start an HVAC business here and take your call.
For an installation like this, the check comes from the local building office instead of a license. Replacing a furnace, air conditioner or heat pump needs a permit in most cities and counties, and an inspection once the work is done. That inspection is what stands between you and a bad gas connection, since the state itself sets no rule on who does the job.

- When should I replace my HVAC system?
- Start planning a replacement once your furnace or air conditioner is into its second decade, or if it is breaking down more winters than not. In this area the furnace runs September through May, nine months of the year, and a failure on a night averaging 3°F is not a small inconvenience. Watch for rising repair calls, uneven heat between rooms, and a technician telling you parts are getting hard to find. Replacing it on your schedule instead of the day it quits gives you time to pick the right size system and the right contractor.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is usually the better move, though it is not required. A furnace and air conditioner installed at different times often were not matched to work together well, and pairing new equipment as a set tends to run better than mixing an old outdoor unit with a new one indoors. Since homes here need heat nine months a year and cooling three, the furnace does most of the work and wears the most, so it may need to go first. A contractor can look at the age and condition of both and tell you whether it makes sense to do one now and plan the other, or replace them together.
- What happens during an HVAC installation?
- A contractor removes the old furnace or air conditioner, sets the new equipment in place, and connects it to your ductwork, gas line or electrical circuit, and the vent or flue. Once it is connected, they test the system, check refrigerant charge on an air conditioner, and confirm the furnace fires and heats correctly. Most cities and counties require a permit for this work and an inspection when it is done, so the contractor should be pulling that permit as part of the job. Ask what is included in the install and what the inspection will cover before the work starts.
