I was sent to check out a leak coming through a ceiling at a business. When I got there, the condensate line was plugged up. The overflow went into a drain pan...that had been plugged off with caulk and duct seal...duh!!! I fixed those and as I was leaving, I looked at the lineset and noticed it was frosting up. Then it hit me...I didn't hear the furnace fan. I figured a bad cap or motor so I crawled out of the attic(150ft and half of it was CRAWLING) to go get my meter. I crawled all the way back and got ready to meter the low voltage, just to make sure the fan was getting a call. That's when I saw it(look at the two wires on the bottom that go to the condensor)...What the heck????? Soooo, I just had to crawl back out to get my phone to take pics to show everyone. When I asked the ladies downstairs how it heated in the winter, they told me they had to bring in their own portable heaters...wonder why? No, I did not check out the heating side of it...way too hot and too far to crawl back in there again. I'll do it if they want this fall. I feel like I just completed my first novel.
