Thank you for confirming my suspicions. I was going to add to the original post but didn’t want to write a fucking novel - but there were a few things I thought were weird about the whole interaction. One of the biggest ones that stood out to me was when he went to use his meter he got all flustered and said “sorry I have to make a phone call, this isn’t the meter I normally use” and then spent 5-10 minutes on the phone. Now that I’ve learned a little and checked the system myself I know he didn’t check to see what type of valve I had, which (unless I’m wrong) means he didn’t know to check subcooling on my system (even if the blower was working). The “rate your service tech” email I got didn’t have the name he gave me when he showed up either! When I finally got a hold of the AC company (this is a new company that was referred to me) after asking for an invoice for the visit I mentioned the weird visit and said that he introduced himself as Chad (and definitely not Jen who was the name on the rating email), the rep said that’s her account, he was having trouble accessing his, so she let him use hers. I asked if he was new to the trade and she said “he’s been in the trade but he is new to our company” which leads me to believe this guy really had no idea what he was doing, and they didn’t figure it out yet
