May 18-2008, Toni from United air care came to my house for clean up air way system, he introduced U.V light cleanser & life time warranty for filters, U. V light kill bacteria etc...Filters clean air up to 99%...U.V light cost $750 and filter cost $200 each I buy 3 filters..and every 2 years come to my house for free service and clean up air way system for free up to 12 years..
May 19-2010 I call United Air Care for service and clean up air way system, they said that is not for free, only free is check for u.v light is working properly or not, i said o.k come to my house check for my u.v light . they said o.k they will call me back for make appointment, I wait and wait one week after nobody calling me..I call them again and they said the same thing again...and i wait and wait and today June 5-2010 I was so mad I call them and they put me on hold for so long and they said they don't care how much i pay they don't give me the service anymore.
