Hints For The Home
During annual housecleaning, there’s one place even the most fastidious families can forget: heating and air-conditioning ducts. This can be a problem since dirty filters let in dust, dander, and mold spores and make the system work harder, use more energy and wear out faster. Fortunately, you can fix this. Have the ducts cleaned by a member of the National Air Duct Cleaners Association. They’re trained and tested regularly and clean and restore H-V-A-C systems in accordance with industry standards.
