Judging from the web site and the youtube videos, it's looks like these people really know their stuff. Don't ask me though as I don't have a clue. I never got the opportunity to do business with them. My system is cold but old. I requested a quote for a completely new system. I waited from 8AM to 3:30PM (the on the way call) and finally cancelled at 5PM as there still wasn't anyone there. If there's not time for new business, it's only prudent to assume there will not be time for emergency calls. Of the few employees I did talk to, I found them genuine and very, very polite.

Upgrading from 1 to 4 stars. Customer service scheduled another appointment and was very helpful. Bubba showed up on time and was very knowledgeable and honest. My estimate was completed as requested. I would recommend A#1.
