The only appointment time wasn't until the afternoon

I heard a actually odd plus different sound coming from the air duct in our study room.

At first I thought it was normal cracking plus creaking, however then the noises sounded more love an pet.

I thought there could be a problem with mice, however the problem was honestly coming from the air duct, so I contacted the local Heating, Ventilation plus A/C Center. I wanted to set up an appointment for the next afternoon, however the Heating, Ventilation plus A/C provider was busy plus did not have any available appointments until the afternoon. The lady on the iphone was actually nice plus accommodating, so I made the appointment. I did contact a couple of different Heating, Ventilation plus A/C providers, however none of them could get to me any earlier, so I kept the appointment with the company that I knew plus trusted. I waited all afternoon before the worker arrived plus it was really after 3 when the woman showed up. She instantaneously went into the attic so she could look at the condition of the air duct. She did not guess that the noises were coming from any pets. She did not find evidence of rats, mice, or even insects inside of the air duct. There were some locations where the air duct needed to be reattached, plus the repair worker felt that was the reason why I heard the odd sounds in the middle of the night. She assured me that the same sounds were actually happening during the afternoon, even though I only heard them at night when everything else in the cabin was quiet. The repairs to the air duct were reasonably priced plus I haven’t heard any sounds at all since the repairs were made.
