Three months of hard running, then hail and wind

Your air conditioner in Moline gets three months to do its work, June through August, with afternoons averaging 83°F. It runs hard in that stretch, and the capacitor and the contactor take the wear. A weak capacitor can't get the compressor started, and the unit just hums or clicks without kicking on.

Rock Island County has logged 34 hail events and 87 damaging wind events over the past ten years, with hail up to 3 inches. That kind of storm bends the thin aluminum fins on the outdoor unit and can crack the fan blade or knock the unit out of alignment. After a bad storm, listen for a new rattle or grinding sound when the outdoor unit runs.

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

  • A new one at the federal minimum, 13.4 SEER2$230 a year
  • An older air conditioner$250 a year

Estimates for a typical Rock Island County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Illinois 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.

In Illinois, HVAC licensing for homes is left to the cities and towns.

Rock Island County does not run its own HVAC licensing program, so there is no local trade license to check here the way there might be in a city that requires one. Illinois leaves that decision to individual cities and towns, and Rock Island County has not stepped in to fill the gap with its own rule. That means no license, city or state, stands between you and the contractor you hire for this repair.

What does apply is federal. Fixing an air conditioner almost always means opening the refrigerant side of the system, and anyone who does that anywhere in the country has to hold EPA Section 608 certification. That certification is not a state or local license. It is proof the technician passed a federal test on handling refrigerant safely and legally, and it applies the same in Rock Island County as it does everywhere else.

Why is my AC not blowing cold air?
Most of the time this comes down to a dirty air filter choking off airflow, low refrigerant from a leak, or a frozen evaporator coil. A filter clogged enough can drop cooling fast, and it's the easiest thing to check yourself before calling anyone. If the filter looks fine, feel the vents. Weak airflow points to the blower or a frozen coil, while decent airflow that's just not cold points to the refrigerant side, and that needs a licensed contractor to diagnose.
Why is my AC leaking water?
Your AC makes condensation as it cools the air, and that water is supposed to drain out through a condensate line. When that line clogs with algae or dirt, the water backs up and finds another way out, usually into the pan or onto the floor near the indoor unit. A frozen coil that then thaws will cause the same kind of leak. Either way, a contractor can clear the line or find out why the coil froze in the first place.
Why won't my AC turn on?
Start with the thermostat. Check that it's set to cool and below the current room temperature, and that it has power or working batteries. If the thermostat looks right, check your breaker panel, since AC units trip breakers more than people expect. If the breaker keeps tripping when you reset it, stop and have a contractor look at the unit instead of resetting it again.
