The sound wasn't the Heating, Ventilation as well as A/C after all

The repairman told our wifey and I that the sound was not coming from the plan and appeared to be a piece of metal linked to one of the air duct linkions

My wifey and I noticed some strange sounds in the bedroom and they appeared to be coming from the air duct above the bed, then i tried to go into the attic to find the source of the sound! When the Heating, Ventilation as well as A/C component was running, it was strenuous to determine where the sound was coming from, however since I was pretty sure that the sound was coming from the air duct, I decided to contact the local repair service. They came to help us on Monday, when our wifey and I were both beach house at the time. The repairman performed a complete maintenance tune up on the heating and air conditioner plan and she also looked for the location of the strange sound. The repairman was in the attic for a while, but she had the air conditioner plan turned off while she was in the attic, maybe that was the reason why I could not locate the sound, because I did not turn off the Heating, Ventilation as well as A/C plan during the attic. I thought the noise was coming from the system, so I left it on. The repairman told our wifey and I that the sound was not coming from the plan and appeared to be a piece of metal linked to one of the air duct linkions. The repairman secured the piece of metal with a screw and encouraged us to keep listening for the sound. She believed it was not going to come back, however told us to listen carefully. The repairman found the source of the noise and she performed a tune up while she was at the house.
