Comments: The technician was mature and knew what he was talking about. No substitute for experience! My fan motor/system sounded like the motor was going bad. This actually went on for several months and I finally decided to have you guys come give me a quote for replacing and he said, how long have you had it off and I said a few days. Well, we cut it on and it sounded great! He said, frequently something will get in there and create noise. I was convinced he was wrong, so I said, okay, but if you have to come back it would be an inconvenience. Well, 6 weeks later and it’s doing well! Thank you!!
