Three months of hard summer work

Your air conditioner in Whitewater only gets three months to do its job, June through August, and it does it against afternoons averaging 81°F. That kind of steady demand puts real hours on the compressor and the fan motor, the parts that run longest when the heat sits in the mid-80s day after day.

Walworth County has also seen 74 damaging wind events and 43 hail events over the past ten years, with hail up to 2.5 inches. Wind that strong can bend the thin fins on your outdoor unit or knock loose the electrical connections, and hail that size can dent the cabinet or damage the coil underneath it. If your system is blowing warm air or the outdoor unit sounds different than it used to, one of these is often why.

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

  • A new one at the federal minimum, 13.4 SEER2$180 a year
  • An older air conditioner$190 a year

Estimates for a typical Walworth 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, nothing more. Nobody tests the contractor's HVAC knowledge before handing it out, and no state agency is grading the work itself. Because Wisconsin holds this authority statewide, no county or city in Walworth County can layer on its own HVAC licensing requirement, so this registration is the whole of it wherever you are in the county.

For a repair on an air conditioner, the protection that matters most doesn't come from that state registration at all. Any technician who opens the refrigerant lines on your system, which most AC repairs require, has to hold EPA Section 608 certification. That's a federal credential, earned by passing an exam on handling refrigerant safely, and it applies to this repair no matter what state you're in.

Why is my AC not blowing cold air?
The most common reason is a dirty air filter choking off airflow across the coil. When air can't move past the filter, the coil can ice over and what comes through the vents turns warm. A low refrigerant charge from a leak causes the same thing, and so does a failing compressor. Check the filter first, since that's the one thing you can rule out yourself before a contractor looks at the rest.
Why is my AC leaking water?
Usually the drain line is clogged and condensation is backing up instead of draining outside. Algae and dust build up in that line over a season and block it. A dirty filter can also cause this, since it lets the coil ice over, and the water shows up when that ice melts faster than the drain can handle it. Either way, a contractor can clear the line and check whether anything upstream caused the clog.
Why won't my AC turn on?
Start with the thermostat and the breaker. If the thermostat screen is blank or unresponsive, it may need new batteries or has lost power. A tripped breaker will also keep the unit from starting at all. If both of those check out and it still won't run, the capacitor or the contactor inside the outdoor unit has likely failed, and that's a repair for a contractor to diagnose.
