What we did
The downstairs air conditioner in this Lexington home would not cool below 72 degrees. It came to us as a thermostat issue, and in March 2026 we came out to find the real cause.
During the visit we discovered a missing cap on the inducer motor drain ports. Without that cap in place, the inducer sensor was shutting the system down, which caused it to short cycle, turning on and off before it could finish a full cooling run. That explained why the house never reached the temperature on the thermostat. We repaired the issue so the air conditioning system could run properly again.
This job is a good example of why a symptom at the thermostat does not always mean the thermostat is the problem. A small missing part elsewhere in the system was enough to interrupt the whole cooling process. Short cycling also puts extra wear on equipment, since frequent starts are harder on components than steady operation. In Kentucky, where summer humidity makes a properly cooled house important for comfort, finding the actual cause matters. If your system turns on and off frequently or will not reach its set temperature, call us and we will dig into it.
