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.

A system working harder than it should to hit the same setpoint is a system with a developing problem, even if it hasn't fully failed yet. Our Saint Marys, IA techs see this specific pattern often enough to diagnose it quickly rather than guess.
