Compressor Running but No Cooling Output – The Sneakiest Failure

Sometimes the system sounds normal, but no cool air comes out. The compressor hums, fans spin—but the refrigerant circuit isn’t moving heat.
Chatterbox detects this by comparing compressor current, coil temperature change, and airflow data. When the compressor works but coil temps stay flat, it’s a sure sign of a stuck valve or internal failure.
This early alert prevents hours of wasted runtime and speeds repair before total failure.
Chatterbox ensures you know what failed, why it happened, and how to fix it—before comfort is lost.
