**SCAM ALERT** This spoofed number is being used by GGS Air who claims to come to your place and clean your air ducts. Their rep stated that they did work at our home in 2005. I stated we've lived here since 1998 and we have not had GGS Air clean our ducts, and I don't appreciate this type of sales tactic. Their spoofed telephone number is also questionable. I looked them up on the web. They have a simple, 4-page website (ggsair.com) that could have been created in an hour. No address on their website and their phone number (866-472-4748) is not being answered by anyone.
