When i clean air ducts and see very dirty vents, i always start by vacuuming to prevent dust from going into the house. Our machine scrubs and santizes the ducts after, resulting in amazingly clean air ducts. If you see any dust or dirt on the vent covers, it usually means the inside is much worse and needs a cleaning. We are based in Waynesboro Pa and service the surrounding areas 😁 #ductcleaning #satisfying #cleantok #satisfyingvideo #homemaintenance #wow #asmr
