At ZACH-VAC we provide residential & commercial air duct and dryer vent cleaning throughout South Central PA and Berks county. We have certified ASCS (Air System Cleaning Specialists) for air duct cleaning. That certification is by NADCA, the National Air Duct Cleaners Association. In addition our technicians are certified in dryer vent exhaust cleaning by the Chimney Safety Institute of America, CSIA. "We're bringing honesty and trust back to duct cleaning." No bait and switch pricing...EVER! We also provide easy over the phone pricing for residential homes. All we need is the square footage of the home and a few other details. This makes quoting for you and ZACH-VAC easy. We also provide remediation for mold inside of ducts and offer encapsulation so it doesn't return. Our HVAC partners trust us to clean their customer's ducts, so you should too! **BEWARE OF ROTOBRUSH, RAM AIR SYSTEMS, and other shop vac style "cleanings" ** These aren't used by any reputable company.
