Green Bay air conditioners work a short, hard season
Your air conditioner only gets two months of real work, July and August, and summer afternoons here average 78°F. That is not extreme heat, but it means the system sits idle most of the year, then gets asked to run hard with little warm-up.
Brown County has logged 78 damaging wind events and 29 hail events over the past ten years, with hail up to 2.5 inches. The outdoor unit takes that weather directly. Wind-blown debris can bend the fins on the condenser coil, and hail can dent the cabinet or damage the fan. If your AC is running rough or not cooling like it used to, a short summer and a long stretch of exposure to rough weather are often part of the reason.

A new air conditioner would save little on running costs in Brown County, so the repair decision comes down to the unit's condition.
Estimates for a typical Brown 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.
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 license the trade. Because counties and cities in Wisconsin cannot layer on their own HVAC license, that state record is the only one that exists anywhere in Wisconsin. There is no local licensing board picking up what the state does not cover.
For a repair on your air conditioner, the credential that actually applies is federal. Anyone opening the refrigerant side of your system, which a repair like this usually requires, has to hold EPA Section 608 certification, and that rule holds in every state regardless of what Wisconsin does with registration. That certification is the one thing here that was actually tested.

- 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 up, and once it's iced over the air coming through the vents turns warm even though the unit is running. Low refrigerant from a leak causes the same warm-air symptom, but that's not something to test yourself since it means opening a sealed system. Check the filter first. If it's clean and you're still getting warm air, the system needs a contractor to look at the coil and refrigerant charge.
- Why is my AC leaking water?
- Almost always it's the condensate drain line, and it's either clogged or disconnected. Your AC pulls a lot of moisture out of the air on a summer afternoon, and that water is supposed to run out through the drain line to the outside. Algae and dirt build up in that line over a season and block it, so the water backs up and drips inside instead. A frozen coil that's now thawing will do the same thing, so if the air was blowing warm before you saw the water, that's likely the real cause.
- Why won't my AC turn on?
- Start with the thermostat and the breaker before assuming the worst. Check that the thermostat is set to cool and a few degrees below the room temperature, since a dead thermostat battery will leave the display blank or unresponsive. Then check the breaker panel and any shutoff switch near the outdoor unit, since a tripped breaker will stop the whole system cold. Green Bay gets a fair number of damaging wind events each summer, so a tripped breaker after a storm is worth checking first. If power is reaching the unit and it still won't start, the capacitor or the compressor itself may have failed, and that calls for a contractor.
