Three months of hard running, then storms on top of it
Your air conditioner in Watertown gets three months to do its job, June through August, with afternoons averaging 81°F. That's a short season, but it's a demanding one. The system runs long hours trying to keep up, and the compressor and the fan motor take the brunt of it.
Jefferson County has also seen 30 hail events and 60 damaging wind events over the past ten years, with hail up to 1.75 inches. Hail that size can dent or puncture the thin aluminum fins on your outdoor unit, and high winds can knock the unit out of level or drive debris into the coil. If your AC is running weak or short-cycling after a storm, the outdoor coil is the first place to look.

A new air conditioner would save little on running costs in Jefferson County, so the repair decision comes down to the unit's condition.
Estimates for a typical Jefferson 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 state, with a name and address on record, but nobody tested the contractor's work to get it. Wisconsin doesn't run a trade exam for HVAC contractors, and counties and cities here can't step in with their own license requirement either, so this registration is the only state record that exists on a contractor anywhere in Wisconsin.
For a repair like this one, the protection that actually applies comes from outside that registration. Since the job means opening the refrigerant side of your air conditioner, whoever does the work has to hold EPA Section 608 certification, a federal requirement that applies to that kind of work in every state. That certification is what says a technician has been tested to handle refrigerant safely. The state registration doesn't test for that. The federal certification does.

- Why is my AC not blowing cold air?
- The most common cause is a dirty air filter choking off airflow, so start there. A refrigerant leak will also cause this, usually with ice forming on the indoor coil or the line running outside. If the outdoor unit isn't running at all while the indoor fan blows, the compressor or a capacitor has likely failed. A contractor needs to check refrigerant charge and pressures to know which one it is.
- Why is my AC leaking water?
- Most water leaks come from a clogged condensate drain line, which backs up and overflows instead of draining outside. A dirty air filter can also cause this indirectly, by freezing the coil, then dripping as it thaws. Less often, the drain pan itself has rusted through or cracked. A contractor can clear the line or check the pan to find the actual source.
- Why won't my AC turn on?
- Check the thermostat first, since dead batteries or a setting knocked off cool will stop the system before it starts. If the thermostat looks fine, a tripped breaker or a blown fuse at the outdoor unit is the next likely cause. With Watertown's summer storms bringing damaging wind and hail, a breaker can trip during or after a power surge. If the breaker won't stay reset, a contractor should look at the unit before you try again.
