Received an unsolicited call to my business line from this number, claiming to be part of "Patriot Air Conditioning and Plumbing."   Was pushy but not so much as it was unusual for a cold sales call.  Said we weren't interested but that he could e-mail information for me to hold on to.  http://www.yelp.com/biz/patriot-air-conditioning-and-plumbing-mesa this doesn't inspire a lot of confidence though.
