Three months of hard running, then storms on top of it
Your air conditioner in Fond du Lac County has a short season to do its job. June through August, with afternoons averaging 79°F, it runs hard because it doesn't get to ease into the work over a long stretch. That kind of steady demand wears on the capacitor and the contactor, the parts that start the compressor and keep it cycling. When one of them goes, the unit hums but the compressor doesn't kick on, or it shuts off on its own partway through the afternoon.
The county has also logged 29 hail events and 59 damaging wind events over the past ten years, with hail up to 3 inches. Hail that size dents the fins on the outdoor coil and can bend the fan cage, and wind drives debris into the unit or knocks it out of level. Either one shows up as an air conditioner that runs but doesn't cool like it should.

A new air conditioner would save little on running costs in Fond du Lac County, so the repair decision comes down to the unit's condition.
Estimates for a typical Fond du Lac County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Wisconsin 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.
Wisconsin requires contractors to register with the state.
That registration puts the business on file with the Department of Safety and Professional Services. Nobody tested the contractor's work to get that number, and the state does not grade or rank them because of it. Wisconsin also keeps counties and cities from layering on their own HVAC license, so the registration is the only state-level record you get, no matter where in Fond du Lac County the work happens.
For a repair on your air conditioner, the protection that actually matters is federal. Any technician who opens the refrigerant side of your system, which a repair like this usually calls for, has to hold EPA Section 608 certification. That certification is what says someone checked this person knows how to handle refrigerant safely. It is not a state license and it does not cover the rest of the job, but it is the one credential the law requires before anyone touches that part of your unit.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter choking off airflow across the coil. When that happens the coil can ice over, and once it's iced, the air coming through the vents turns warm no matter what the thermostat says. Low refrigerant from a leak causes the same thing, but that's not something to check yourself. Start by looking at the filter, and if it's clean, a contractor needs to check the refrigerant charge and the coil.
- Why is my AC leaking water?
- Water around your unit usually means the condensate line is clogged. Your AC pulls a lot of moisture out of the air on a humid afternoon, and that water is supposed to drain outside through a small drain line. Algae and dirt build up in that line over time and block it, so the water backs up and drips out wherever it can, often inside near the indoor unit. A frozen coil that's thawing can also leave water behind, so if the airflow's been weak too, mention that to whoever comes to look at it.
- Why won't my AC turn on?
- Check your thermostat first, since dead batteries or a setting knocked off cool are the simplest explanation. If the thermostat looks fine, check the breaker panel, since a tripped breaker will shut the whole system down. Summer storms here bring damaging wind often enough that a breaker trip after a storm isn't unusual. If the breaker keeps tripping once you reset it, stop resetting it and have a contractor find out why.
