In late July, 1997 my husband, Stephen and I parted with $ of hard-earned cash to get our home air ducts cleaned. Our house was fifteen years old and the heating and ventilating ducts had never been serviced. It had been on the "to-do" list since we purchased the house. When we stumbled across a $ off coupon in Clipper Magazine for a local cleaning service, "Pro Clean Environmental Services," we scheduled the work.
