Air duct cleaning is recommended every 4-5 years for average homes.
Removing only 4 inches of dust from the coils of the cooling system will reduce power consumption by 21 % and extend the life of the system
Indoor air quality is a very important for our health. In fact, according to National Air Duct Cleaners Association in a typical six-room home, up to 40 pounds of dust is created annually through everyday living. Dirty ducts may be contributing to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies.
A dirty vent, however, is only one link in possible chain of events that may include: excessive lint build up inside the dryer , a missing or damaged lint screen , a crushed hose behind the dryer and a failure of thermostat and limit switch in the dryer.
