Horrible, horrible, horrible!! I have never experienced such unprofessionalism. The "tech" showed up with his girlfriend wearing a "dads against daughters dating shirt" took a flashlight, looked at my tank and said it needed to be replaced. No tests, didn't even turn on the water. He said the tank needed to be replaced. For literally telling me something I could have made up myself. I stupidly paid the $85 charge for a 5 minute look. Oh and when I came to my senses to cancel the check about an hour later...it was already cashed. Shameful and I will be contacting the BBB.
