Nowadays most houses have a central air conditioning system linking air ducting to move conditioned indoor air throughout the house. Gradually, the air system and the linking air ducting will collect dust and other contaminants, which can trigger the blood circulation of unclean and contaminated indoor air through your house. Out-of-sight and out-of-mind health products that we do not believe much about are filthy air system and a duct which could be the unhealthiest product in our house.
Air duct cleaning is done by heating, ventilation and air conditioning (HVAC) professionals. The pros use industrial-strength, truck-mounted vacuums and powerful brushes and hoses to clean inside the metal ducts that make up your forced air heating and cooling system. The Environmental Protection Agency recommends duct cleaning if there is “substantial visible mold growth inside hard surface ducts, ducts that are infested with vermin such as rodents or insects, or ducts that are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.”
