A new system here has to handle nine months of heat and three of cooling
Winter nights in Chisago County average 8°F from December through February. A new furnace has to bring the house up from that every night for months, not just on the coldest week of the year. Summers are mild by comparison, averaging 80°F in the afternoon, but the same system needs to handle that heat too. Between the two, something in your home is working nine months of the year on heat and three months on cooling, which adds up to all twelve.
Most homes in the area heat with gas, and a new furnace has to meet the federal minimum efficiency rating for this region. The winters here are cold enough and long enough that the choice of equipment matters more than it would somewhere milder. Storms are part of the picture too. Chisago County has seen 25 winter storms and 29 damaging wind events over the past ten years, and statewide, 13% of households lost power for at least 24 hours in 2024. A furnace with a standing pilot will keep running through an outage like that. One with electronic ignition will not light until the power is back, though most start up on their own once it is.

Minnesota has no state license for HVAC contractors.
There is no state list of approved HVAC contractors to check here, and no state exam behind the work being done on your system. Minnesota leaves that ground uncovered, so nothing at the state level is testing or tracking who does this kind of work.
For a job like installing a furnace or air conditioner, the protection in Chisago County comes from the local building office instead. In most cities and counties, a job like this needs a permit and an inspection once the work is finished, and that inspection is what catches a bad gas connection or a system put in wrong. That check is separate from any license, because there is none behind it here.

- When should I replace my HVAC system?
- Once your furnace or air conditioner needs repairs more than once a season, or a repair costs a lot next to a new unit, replacement is usually the better move. An older unit working harder than it used to is a sign the end is near. Here your furnace runs from September through May, so one on its last legs going into an 8°F winter is a real risk, not just an inconvenience. If yours is struggling to keep up now, get it looked at before the cold sets in rather than after it fails.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often worth considering, even though it is not required. A furnace and air conditioner installed at different times can still work fine side by side. But if they were installed around the same time originally, they are likely to wear out around the same time too, and doing both in one visit means one inspection instead of two. A contractor can look at the age and condition of each and tell you whether it makes sense to wait on one or replace both now.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner or heat pump in place, and connects it to your ductwork, gas line or electrical, and refrigerant lines as needed. They check that the system is sized right for your house, test it once it is running, and make sure it cycles the way it should. In most places around here, a permit and inspection are required for this kind of job, since there is no state license for HVAC contractors in Minnesota, so the local building office is what confirms the work was done to code. The contractor pulling the permit is a good sign they plan to stand behind the work.
