Four months of hard running, then storms on top of it

Quincy summers push your air conditioner into steady work from June through September, with afternoons averaging 85°F. That kind of heat means the compressor runs long stretches to keep up, and the parts that start it and cool it take the wear. A capacitor that's been struggling to get the compressor going will start hesitating on hot afternoons, then stop working at the worst possible time.

Adams County has also seen 33 hail events and 48 damaging wind events over the past ten years, with hail up to 4.5 inches. Hail dents the thin aluminum fins on the outdoor unit and can bend the coil behind them, cutting down how well it sheds heat. After a storm, a unit that used to keep the house cool may start running longer without getting there.

A new air conditioner would cut about $30 a year off cooling for a typical Adams County home.

  • A new one at the federal minimum, 13.4 SEER2$280 a year
  • An older air conditioner$310 a year

Estimates for a typical Adams 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.

Adams County does not run its own contractor licensing program, and Illinois does not either, so there is no state or county credential to check on this repair. Whether a town nearby requires registration or an exam is a local matter, town by town, and it may not apply outside city limits at all. That leaves this job resting on other things.

An air conditioner repair almost always means opening the refrigerant side, and federal law requires whoever does that to hold EPA Section 608 certification, no matter where the house sits. That certification is not a state license and does not test general repair skill. It confirms the technician is trained to handle refrigerant without venting it into the air. Beyond that, nothing in Adams County stands between this reader and the person doing the work.

Why is my AC not blowing cold air?
The most common reason is a dirty air filter choking off airflow across the coil, which can cause it to ice up and blow warm. Low refrigerant from a leak is another common cause, and that will not fix itself, a contractor has to find the leak and repair it. It could also be a failing compressor, which is worth having checked before it fails completely on a hot afternoon here.
Why is my AC leaking water?
Most often the condensate drain line is clogged, so the water your AC normally removes from the air backs up and drips out instead of draining away. A dirty air filter can also cause this by letting the coil ice over, then the ice melts faster than the drain can handle. A contractor can clear the line and check whether anything else caused the clog in the first place.
Why won't my AC turn on?
Check the thermostat first, a dead battery or a setting bumped to off or heat will stop the AC from starting. If the thermostat looks right, check the breaker, since a tripped breaker will cut power to the whole system. If the breaker keeps tripping when you reset it, that points to an electrical problem inside the unit, and that needs a contractor to look at rather than resetting it again.
