Called me this afternoon, Caller ID came up as "air duct cleaning" in all lower case letters. I get tired of these calls so I answer and then hang up. Maybe they will get the idea.
Just got a call from this number. Identified himself as AA Air Service and said they serviced our a/c in 2009 and still had a second, free service. He asked if we still had one unit. Told him we've never had just one unit and coincidentally, our regular a/c guy was here for our regular service. He hung up.
