Company Profile

    Alliance Water Conditioning & Plumbing Inc. is a family owned and operated business founded in 1973 by Scott and Mary Duncan. Their philosophy was to provide their customers with the same high level of service and value that they wanted and expected for themselves. Now, over fourty years later, that tradition continues with eldest son David Duncan at the helm. He and the crew at AWC Inc. strive to provide the same high level of honesty, service, solid workmanship and value to their customers as they want for their own families and homes.

    And speaking of families, at A.W.C. Inc. we think of ourselves as one big family. We consider it an honor and a privilege to have a solid core of both highly skilled veteran service technicians and responsible young people who are being raised up in the trades to carry the torch into the next generation and beyond.
