I have been doing business with Clearwater Systems Hamilton & Missoula, MT for about three years and it has been a great experience. They installed my system and are always prompt when I call for service. I would describe all the servicemen as polite, hard-working, and friendly. I will definitely be using them in the future and would recommend them to a friend. Their product is excellent, and their customer service is outstanding. They bend over backward to take care of you.
