Joe, arrived within 15 minutes of when he said he would arrive. He listened to my issue and went to work on resolving it. He determined that everything was working as designed but would check and see if there was a way to slow the fan down and he would get back to me. The next morning he call me to say he had contacted the manufacturer and he could slow the fan down if I wanted him to. I decided to leave it as it was installed.
