Three months of hard running, then storms in between

Your air conditioner in Sauk County only gets three months to do its job, June through August, and it runs hard through all of them. Summer afternoons averaging 80°F mean the compressor and condenser fan cycle on and off for most of the day, all season, with no easy stretches to rest.

Sauk County has also logged 22 hail events and 61 damaging wind events over the past ten years, with hail up to 1.75 inches. Hail that size dents and bends the thin aluminum fins on your outdoor unit's coil, and wind can knock the unit out of level or drive debris into it. If your air conditioner is blowing warm air or the outside unit sounds different than it used to, a storm may be part of the reason.

A new air conditioner would save little on running costs in Sauk County, so the repair decision comes down to the unit's condition.

  • A new one at the federal minimum, 13.4 SEER2$170 a year
  • An older air conditioner$180 a year

Estimates for a typical Sauk 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 is tested to get on that list, and nothing beyond the paperwork is checked. Counties and cities in Wisconsin are not allowed to add their own HVAC license on top of it, so this filing is the only state record that exists here.

For a repair on your air conditioner, the protection that actually applies comes from outside the state. Anyone who opens the refrigerant side of your system has to hold EPA Section 608 certification, and that rule holds in Wisconsin the same as everywhere else. It is a federal credential, tied to the person doing the work, not a state license tied to the business.

Why is my AC not blowing cold air?
Most often the filter is clogged and starving the system of airflow, or the outdoor unit is dirty and can't shed heat the way it needs to. It could also be low refrigerant from a leak, which won't fix itself and won't get better on its own. If the air coming out is warm or barely moving, a contractor needs to check the refrigerant charge and the coil before the compressor takes damage.
Why is my AC leaking water?
The drain line that carries condensation away is probably clogged, so water is backing up and finding another way out. Algae and dust build up in that line over time, especially after months of steady use. A dirty or frozen coil can also drip once it thaws, so if the system has been running nonstop through a hot stretch, that's worth checking too.
Why won't my AC turn on?
Check the thermostat first. Make sure it's set to cool and the batteries aren't dead, since that stops a system before it ever starts. If the thermostat looks fine, the problem is likely a tripped breaker or a blown fuse at the outdoor unit. Baraboo sees its share of summer storms, and a power surge or lightning strike during one of them can knock out the electrical components an AC needs to start.
