Three months of heat, then storms on top of it
Chaska homes only need cooling from June through August, but those three months average 80°F in the afternoon, and the AC runs hard the whole time. A unit that sits idle most of the year and then has to work every day in that heat will show any weak part fast, especially the capacitor or contactor.
Carver County has also seen 26 hail events and 51 damaging wind events over the past ten years, with hail as large as 2.75 inches. Hail that size dents the fins on the outdoor coil and can bend its casing. Strong wind throws branches and debris into the cabinet or knocks the unit out of level. After a storm like that, the signs are usually weak airflow or a unit that runs but does not cool like it did before.

A new air conditioner would save little on running costs in Carver County, so the repair decision comes down to the unit's condition.
Estimates for a typical Carver 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 put HVAC contractors through a state exam or keep a license record on any of them. There is no registration list either, so there is no state office you can check a contractor against. Whatever protection exists here comes from somewhere other than a license.
For a repair like this, that protection is federal. Your air conditioner runs on refrigerant, and any technician who opens that side of the system, anywhere in the country, has to hold an EPA Section 608 certification. That is not a state credential, but it is a real one, and it means the person working on the sealed system has been tested on handling refrigerant safely.

- Why is my AC not blowing cold air?
- Usually it means the refrigerant is low or the airflow across the indoor coil is blocked. A dirty filter can choke off airflow enough that the coil ices over, and once that happens the air coming out feels warm even though the system is running. A refrigerant leak does the same thing from the other direction, since the coil needs the right amount of refrigerant to pull heat out of the air. Checking the refrigerant charge means opening the sealed side of the system, and by federal law only a technician with EPA Section 608 certification can do that.
- Why is my AC leaking water?
- Most of the time the drain line is clogged. Your AC pulls moisture out of the air and that water is supposed to run out through a condensate drain, but algae and dirt build up inside that line and block it over time. When it backs up, the water finds another way out, often through the drain pan or wherever the line runs. A cracked drain pan or a coil that has iced over and then melted can cause the same thing, so the fix depends on which one it is.
- Why won't my AC turn on?
- Start with the thermostat and the breaker before assuming the worst. A dead thermostat battery, a tripped breaker, or a blown fuse at the outdoor unit will all stop the system cold without anything being wrong with the AC itself. If those check out, the capacitor that starts the compressor may have failed, which is a common reason a unit hums but never kicks on. A contractor can test the capacitor and the electrical components to find which one is the problem.
