AC On But No Air from Vents?
When your outdoor AC unit runs but no air comes from your indoor vents, the problem is with the air distribution system. This is distinct from an AC that cools poorly — here, air simply isn't moving. Lancaster AC Repair Pro diagnoses and repairs all AC airflow failures throughout Lancaster County.
Why Is My AC Not Blowing Air?
- Blower motor failure — The indoor blower circulates air through ducts. No motor = no airflow.
- Blower capacitor failure — Blower motor has its own capacitor; failure prevents starting.
- Control board fault — Board may not be sending the start signal to the blower.
- Severely clogged filter — Can reduce airflow to near zero and trigger blower safety shutoff.
- Ductwork disconnection — A collapsed or disconnected duct blocks air delivery.
- Closed registers — Check that all vents are in the open position.
