The air ducts used in a central heating and air conditioning system are usually exposed to a lot of airborne impurities. This includes; hair follicles, dust, pet dander, clothing fibers, chemicals, smoke and many other types of impurities. Most of these impurities usually get trapped in the air filter, but there are many that usually settle inside the air ducts. This means that filtered air can still get contaminated in the ducts before reaching the targeted room. To prevent this, duct cleaning is recommended.
