American Standard air conditioner runs but some rooms are not getting enough airflow

Safety first: Turn off power to the indoor unit before opening duct connections or blower panels.

• Check registers: Ensure all supply and return registers are fully open and not blocked by furniture or rugs.
• Inspect accessible ducts: Look in the attic or crawlspace for disconnected, crushed, or kinked flex ducts feeding problem rooms. Repair or replace as needed.
• Clean blower wheel: Remove the blower assembly and clean dust buildup from the wheel blades to restore airflow.
• Consider balancing: A professional can adjust dampers and evaluate duct design to improve airflow balance.
