Why the house can feel humid while the AC runs
An AC removes moisture best when it has enough airflow and runs long enough to pull humidity out of the air. If the system is short cycling, airflow is restricted, the outdoor coil is dirty, the thermostat is misleading the system, or the drain side is acting up, the home can feel sticky even when cool air is coming from the vents.
When a tune-up may be the right first step
If the AC is cooling but feels tired, runs longer in heavy heat, or the outdoor unit looks restricted, an Outdoor AC Tune-Up - Starting at $80 in Springfield can be the right starting point. It focuses on outdoor coil condition, outdoor electrical/component checks, basic readings, and clear findings.

If the system is short cycling, freezing, leaking water, blowing warm air, tripping a breaker, or not responding correctly, start with a $95 Springfield Diagnostic. Nearby towns may cost more based on drive time and location.
