I have been living in my cabin for the past many years, and I have never had any serious issues at all in the dwelling until recently. I heard some pretty strange noises coming from the attic. I told my brother about the noises, however he thought I was going mad. He came to the dwelling a single afternoon for dinner and we genuinely didn’t hear anything the whole time. My brother genuinely thought I was going crazy, although I swore to the man that I heard different sounds coming from the attic and the ductwork. When I had a tune-up performed on the Heating and A/C appliance, I told the repair serviceman that I was hearing sounds in the attic. He agreed to check on the HVAC duct to see if there were any issues, and the Heating and A/C serviceman found a few odd problems. I had loose HVAC duct in the Attic. It was making awful sounds every time the A/C appliance came on. That could have been the source of the sound that I heard, but it also could have been the mice that the Heating and A/C appliance worker found as well. The guy told me that I needed an exterminator and he told me to call when I have the pest problem under control. He would come back and fix all of the problematic areas in the HVAC duct. The guy told me it was pretty much useless to fix the problems now, because the mice would just make their way back into the HVAC duct to cause more problems. I had to get rid of the infestation before the HVAC duct could eventually be repaired.
