Homeowners are generally good about cleaning their Raleigh NC homes and apartments to eliminate dust and dirt from floors and furniture. However, the hidden deep within the bowels of some homes and buildings, indoor air quality experts agree, lie the seeds of potential problems in the form of dust, mold, pollen, germs, fungi and other microbes and materials that may have accumulated inside heating and air-conditioning duct ventilation systems. These contaminate cause allergy systems and keep the inside of the home or buildings dusty and dirty.
What is particularly troubling, Mr. Ron Nichols (a certified NADCA air duct cleaning contractor) said, is that, in some cases, the heating, ventilation and air-conditioning systems in some homes and buildings are acting like dust-delivery systems throughout the home and buildings.
Mr. Ron Nichols said that workers need to clean the various parts of the air deliver system, including the fan, the coil, the unit housing and the ductwork. The tools they use include a high-efficiency particulate air cleaner, referred to as a HEPA vacuum or some use a negative air system.
”The first thing we’re doing is removing and cleaning all the registers and then brushing and HEPA-vacuuming the transition from the register to the ductwork,” Mr. Ron Nichols said, referring to the process of cleaning the grill-like intake and exhaust grates mounted in walls, floors or ceilings. Once that is done, he said, it is then necessary to brush out and vacuum the interior of the ducts themselves — a project that can sometimes mean cutting temporary access holes in the ductwork in your Raleigh, NC home.
