• incorrect speed from installation: The most frequent root cause found during diagnostic service calls.
• changing ductwork configuration: Often seen in systems that are overdue for maintenance or operating under excessive load.
• adding air conditioning: Can develop gradually over months or years of system operation.
• improper airflow for heating or cooling: Less common but can indicate a developing problem that should be addressed soon.
