Three months of heat, and hail in between
Your air conditioner in Kandiyohi County only has June through August to do its job, with afternoons averaging 80°F. That short season means the unit sits idle most of the year, then gets asked to run hard as soon as summer hits.
The outdoor unit takes the brunt of the weather here too. Kandiyohi County has seen 43 hail events in the past ten years, with stones up to 3 inches, plus 40 damaging wind events over that same stretch. Hail bends the thin aluminum fins on the outdoor coil, and wind can drive debris into the cabinet or knock it out of level. When the fins are crushed flat, the coil can't shed heat the way it should, and you notice the air coming from your vents isn't as cold as it used to be.

A new air conditioner would save little on running costs in Kandiyohi County, so the repair decision comes down to the unit's condition.
Estimates for a typical Kandiyohi 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 does not keep a state record of HVAC contractors at all, so there is no license number to check and no state test behind the person coming to your house. Nothing here is registered with the state either. Anyone can start an HVAC business in Minnesota without proving anything to a state agency first.
For an air conditioner repair, the protection that does exist comes from federal law, not the state. Any technician who opens the refrigerant side of your air conditioner, to recover it, recharge it, or work on the coil, has to hold EPA Section 608 certification. That is a federal requirement in every state, including Minnesota, and it covers the part of the job where a mistake means refrigerant released into the air rather than back into the system.

- Why is my AC not blowing cold air?
- The most common reason is low refrigerant from a leak somewhere in the line. A dirty air filter or a coil caked with dirt can also block the heat transfer that cools the air, so the blower just pushes room-temperature air through the vents. If the outdoor unit is running but the air inside feels barely cool, have a contractor check the refrigerant charge and the coil before anything else. Only someone with EPA Section 608 certification can legally open the refrigerant side to check or add to it.
- Why is my AC leaking water?
- Water around your indoor unit usually means the condensate drain line is clogged. Algae and dirt build up in that line over the season and back the water up until it overflows the drain pan instead of running outside. A frozen coil that then thaws can cause the same puddle, so it is worth checking whether the system was blowing warm air before the leak showed up. Either way, a contractor can clear the line or find what caused the freeze up.
- Why won't my AC turn on?
- Start with the thermostat. Check that it has power, is set to cool, and the temperature is set below the room temperature. If the thermostat looks fine, check the breaker for the outdoor unit, since a tripped breaker will shut the whole system down. With 40 damaging wind events and 43 hail events recorded here over the past ten years, it is also worth a look outside for a branch or debris against the outdoor unit before calling for a repair.
