i called this company to clean my A/c duct. My wife had a 14 day old baby with her home. He first opened the coils & told her that this duct has mold in it & needs cleaning & will cost 950. When he was there to clean the duct only. With the coupon its was priced for $ 69.00. this coupon do not say that it needs to be physically present with paying the bill. They wanted to charge her $520 for that stupid service of 15 minutes.
