A system that runs but never actually cools usually means a refrigerant charge issue, a failing capacitor, or restricted airflow — not something a thermostat adjustment will fix. Ignoring warm air from the vents rarely makes the underlying issue cheaper to fix later.
This pattern shouldn't be ignored — some of the underlying causes carry genuine carbon monoxide risk. Our Yorba Linda, CA techs see this specific pattern often enough to diagnose it quickly rather than guess.
