Three months to do all the work
Your air conditioner in Janesville gets one season to earn its keep, June through August, and summer afternoons here average 81°F. It runs hard for those three months, then sits through the cold stretch until it is called on again.
Rock County has also seen 41 hail events and 78 damaging wind events over the past ten years, with hail up to 2 inches recorded. Hail that size can dent the outdoor coil's fins or bend the cabinet, and either one cuts down how well the unit sheds heat. A tune-up before summer checks the coil and cabinet for that kind of damage, along with the parts that wear from three straight months of running, before the first hot week finds it.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Wisconsin requires contractors to register with the state.
The registration puts the business on file with the Department of Safety and Professional Services. It does not mean anyone tested the contractor's work, and there is no license behind it. Wisconsin also does not let counties or cities layer their own HVAC license on top, so this registration is the only state record that exists on a contractor here.
For a maintenance visit on your air conditioner, the protection that matters is federal, not state. Anyone who opens the refrigerant side of your system, to check the charge or service the coil, has to hold EPA Section 608 certification, and that rule applies the same way in every state. In Wisconsin that certification is the credential doing the real work, since the state's own registration was never built to test anyone.

- What does AC maintenance include?
- A contractor checks refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor that start the compressor. They also check the blower motor, inspect the electrical connections for wear, and confirm the thermostat is calling for cooling correctly. Cleaning the coil matters most, since dirt on it makes the system work harder to move the same amount of heat.
- How often does an air conditioner need maintenance?
- Once a year, in spring before the heat sets in. Janesville only asks the system to run June through August, so a spring check gives a contractor time to catch a weak capacitor or a low refrigerant charge before those three months hit. Waiting until a hot afternoon to find out something is wrong means going without cooling until it can be fixed.
- Is AC maintenance worth it?
- Yes, because most of what fails in a system fails slowly, and a yearly check catches that early. A capacitor that is starting to weaken, a coil that is coated in dirt, a refrigerant charge that has dropped a little all show up in a maintenance visit and none of them are things you can see from inside the house. Skipping it does not break the system right away, but it means those small problems keep building until one of them causes a breakdown, and with only three months of cooling weather here, that is the stretch you want the system working.
