In an “Industry Update,” the National Air Duct Cleaners Association (NADCA) reported in October on the climate of the residential market. The results were mixed: “For some,” according to NADCA, “business was better than ever. Others were tightening their belts and waiting for the eventual turning of the tide.” One Michigan duct cleaner said business was still strong, speculating that many homeowners chose slower economic times to spruce up their homes. Another reported having a “phenomenal” year in Connecticut. But one said, “Business is definitely way down from last year” and another said business for his firm has probably decreased from 15-20%.
