Three months of heat, then hail and wind the rest of the year
Your air conditioner in Winona County only gets three months of real work, June through August, with afternoons averaging 80°F. That short, hard push is what strains it. A unit that sits idle most of the year and then has to carry a full summer often shows problems the moment it starts up in June, a compressor that hums but won't start, a capacitor that gave out over the winter.
The bigger risk here comes from outside the unit. This county has seen 83 hail events and 63 damaging wind events over the past ten years, with hail up to 3 inches. That kind of hail bends the thin aluminum fins on your outdoor unit and can dent or crack the coil itself, and wind that strong can knock the unit out of level or throw debris into it. If your system is running rough or not cooling right after a storm, the outdoor coil is the first place to look.

A new air conditioner would save little on running costs in Winona County, so the repair decision comes down to the unit's condition.
Estimates for a typical Winona 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.
There is no state licensing board keeping a file on HVAC contractors in Minnesota, and no registration list either. That means the state itself does not test contractors or track who is doing this work. Whatever protection exists here comes from somewhere else.
For a repair like this, that somewhere else is federal. Any technician who opens the refrigerant side of your air conditioner has to hold EPA Section 608 certification, and that rule applies in every state regardless of what Minnesota does or doesn't require. It is not a license and it does not cover the rest of the job, the wiring, the airflow, the diagnosis. It only covers the refrigerant.

- Why is my AC not blowing cold air?
- The most common cause is a dirty air filter choking off airflow, so start there before anything else. A clogged filter starves the coil of air and it can freeze over, and once that happens you get weak air or none at all until the ice melts. Low refrigerant from a leak is another common cause, but that's not something you can fix yourself. Refrigerant work requires EPA certification, so a licensed contractor has to handle diagnosis and repair on that side.
- Why is my AC leaking water?
- Water around your AC usually means the condensate drain line is clogged. Algae and dirt build up inside that line over a cooling season and block the water from draining outside, so it backs up and drips near the indoor unit instead. A frozen coil that then thaws can also leave a puddle. If the pan itself has rusted through, the unit will need a contractor to look at it.
- Why won't my AC turn on?
- Check your thermostat first. Make sure it's set to cool and set below the room temperature, and check the batteries if it has a screen that looks dim. If the thermostat looks fine, check your breaker panel, since a tripped breaker will keep the whole system dead. Winona sees its share of damaging wind and hail, and a storm can trip a breaker or damage the outdoor unit without leaving obvious signs, so if the breaker keeps tripping or the unit still won't start, it's worth having a contractor check it rather than resetting it repeatedly.
