Came out to look at a humidifier. The unit looked like it was mounted with duct tape before it fell. There was a lot of mold built up on the interior. I was able to temporarily mount the humidifier back to the duct work for testing. I cranked the humidifier stat all the way but it wouldn’t start. Weather conditions may be the reason it wouldn’t work, however, it looks like it hasn’t ran in quite some time.
