Start with the symptom
AC Running Constantly
Long run time may reflect weather and load, but it can also point to airflow, controls, equipment condition, duct losses, or a building that is not reaching the thermostat setpoint.

What you can document
The pattern is useful evidence.
Note when the symptom happens, which rooms or equipment are involved, and what changed before it started. That information makes an on-site diagnostic more focused.
Useful observations for AC Running Constantly
Air feels cool but rooms do not catch up
Runtime changed from prior seasons
One area drives the whole system
Diagnostic pathway
What a technician may check next.
The exact inspection depends on the equipment, building, history, and conditions observed during the visit.
Potential diagnostic checks
D01
Actual temperature and thermostat behavior
D02
Filter, blower, coil, and delivered airflow
D03
Indoor and outdoor equipment operation
D04
Duct distribution and obvious building-load factors
