To remove the clogged dirt and trapped debris, special brushes are designed to loosen them. Following this process, a high-powered vacuuming should be done. This process is extremely important because, oftentimes, rodents, insects, bacteria and airborne allergens like pollen also make their home in the air ducts. They should be dislodged and the ductwork professionally cleaned. Otherwise, the critters can cause infestation, the bacteria can spread respiratory-causing diseases and the allergens can cause seasonal allergies. This means that dirty air ducts are a health hazard.
The age of your home does not matter. As long as you are running an HVAC system, the air ducts continually collect air pollutants, contaminants and particulate matters. Therefore, they should be cleaned periodically. Their accumulation is bad news for your health and your family’s because when the inside air flow is affected, it dictates what you breathe in.
