Customer had me out because they could hear a weird noise in the upstairs bathroom. I got there and heard the noise myself. I was a semi-high pitch noise, it was not always the same note, and sometimes it was a short burst of noise sometimes it was longer. I could only hear it in the bathroom so I went into the attic above it and I was able to hear it there too. I followed the sound and as I got closer it grew louder so I know I was in the right direction. I followed it to the corner of the eve in the attic and I could go no further as I was already crawling on my stomach. There was no water or drain lines around there so I donâ€™t think it is a plumbing issue. To me it sounded like an animal that was stuck somewhere but I have no way of knowing for sure. I found no further issues at this time.
