Short summers, hard storms
Your air conditioner in Goodhue County only runs June through August, with summer afternoons averaging 79°F. That is a short window, but the unit still has to work the day it turns hot, and one that has sat all winter is where a weak capacitor or a pitted contactor shows up first.
The bigger risk is what sits outside the rest of the year. Ten years of records show 39 hail events and 52 damaging wind events in the area, with hailstones up to 3 inches recorded. Hail bends the thin aluminum fins on the outdoor coil, and wind can drive debris into the cabinet or rock the unit on its pad. You will notice it as warm air from the vents, ice on the coil, or a unit that runs but never quite cools the house.

A new air conditioner would save little on running costs in Goodhue County, so the repair decision comes down to the unit's condition.
Estimates for a typical Goodhue County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Minnesota fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
Minnesota has no state license for HVAC contractors.
Minnesota keeps no record of HVAC contractors at the state level. There is no exam, no license number, and no state list to check someone against. Whether a contractor is any good comes down to their own track record, not a state file.
For a repair like this, the protection that does apply comes from federal law, not the state. Any technician who opens the refrigerant lines on your air conditioner has to hold EPA Section 608 certification. That is a federal requirement in every state, Minnesota included, and it covers the part of the job where refrigerant is handled.

- Why is my AC not blowing cold air?
- The most common cause is a dirty filter choking off airflow across the coil. When that happens the coil can ice over, and once it's iced up the air coming through the vents turns warm no matter what the thermostat says. Low refrigerant from a leak causes the same kind of warm air. Check the filter first since that's the easiest thing to rule out yourself.
- Why is my AC leaking water?
- Usually the drain line is clogged and the condensate has nowhere to go but out. That water is what normally drips off the coil and runs outside through the drain, so when the line backs up it shows up as a puddle near your indoor unit instead. A frozen coil that's now thawing can cause the same kind of leak. Either way it's worth having looked at soon, since water sitting near the unit can damage the floor or the equipment itself.
- Why won't my AC turn on?
- Check the thermostat first, since a dead battery or a setting bumped off cool will stop the system before it starts. If the thermostat looks right, check the breaker, because a tripped breaker is one of the more common reasons an AC won't respond at all. With 52 damaging wind events here over the past ten years, it's worth checking the breaker after any storm that knocked the power around, before assuming something inside the unit has failed.
