One hot room can point toward airflow balance, duct, insulation, or room load issues. Weak air across the whole house can point toward restriction, blower performance, a dirty coil, or a system problem that needs the $95 Springfield Diagnostic.
If the AC still cools but airflow feels restricted, the Outdoor AC Tune-Up can be a practical first look at the outdoor unit and basic operation. It starts at $80 in Springfield. If the house is not cooling, the coil is freezing, or the blower sounds wrong, start with the diagnostic instead.
