Upon arrival, I investigated the noise in question. The blower wheel is spinning out of balance. I confirmed that the blower shaft is not wobbling when it spins, the motor is secure, and the keeper bolt is tight. The wheel is spinning and shaving the blower housing. It appears as if the wheel has warped causing this. Due to the unknown damage that may have happened, it is advised to replace the blower motor, blower wheel, and the blower housing. Customer has not had maintenance and AdonCPS has not been out since the install of the equipment in August of 2020. We will need to reach out to York on Monday to verify warranty and part availability.
