They called back. Additional complaint filed with the FTC.
This time they have a web site (topaircaredallas.com) and also listing on Facebook and Yelp at http://www.yelp.com/biz/top-air-care-dallas which needs to have some complaints put on it.

I got a call this morning at 8:17am from this number. I have an answer machine but when it came on, whoever the caller was, they didn't leave a message. The name on the phone says, Dallas, TX. In my opinion, this isn't a name of a company & is most likely a spoof caller or a crook trying to steal identities.
Probable robo-call. Left message "..single furnace, we will also include a free dryer vent cleaning.. and furnace inspection..To hear more about this offer press 1 or press 2 to be removed." Looking for phones that are answered. Needless to say, message was immediately deleted.
