We purchased our home 3 years ago. It already had the Aquakleen system in it. We purchaded the home from a hispanic person. Aquakleen sends someone out once a year to "SERVICE?" the system. They chance a few filters and charge you hundreds of dollars. Last year the person spoke some english. Today, the person spoke no english, so I could not even tell him how to get to my home. I called the company to complain and got passed around and passed around until they hung up on me. They have not bothered to contact me back. I don't know what the system cost the original owners, but the service cost are a rip off, and the company customer reps stink. I would not refer anyone to this co.
