Air ducts are pathways where heated or cooled air travels throughout a residential or commercial establishment, and it is associated with your heating, ventilation and air conditioning (HVAC) system. Air ducts are common feature of many residential areas, and its maintenance is often overlooked by tenants or homeowners. Aside from the normal accumulations of dirt and dust of air ducts, the other reasons why air duct cleaning is needed are air ducts infested with rodents or other pests, substantial mold growth inside the air ducts, water contamination or damage to the home or HVAC system, home renovation or remodeling projects, cigarette smoking, pets and occupants with allergies or asthma. In residential homes, some occupants are more sensitive to air contaminants than others, and those who have asthma and allergy have increased susceptibility to poor indoor air quality, so air duct cleaning can help address the problem.
Air duct cleaning refers to the cleaning of the various parts of the cooling and heating system that include the supply and return air ducts and registers, heat exchangers, grilles and diffuser, heating and cooling coils, fan housing and motor, condensate drain pans or drip pans, and the air handling unit housing. Unless you understand your cooling and heating system, it is best recommended to get an expert’s advice to check your entire air duct system to be able to assess what exactly needs to be done. The cleaning process associated with air duct systems differs according to each individual property, but it generally involves usage of vacuums and brushes which suck out dust. Air duct cleaning methods commonly used are air duct cleaning include source removal (mechanical agitation and extraction), steam air duct cleaning, truck mounted vacuum cleaning, and point of contact air duct cleaning.
The recommended method for air duct cleaning is source removal, wherein the two key elements are mechanical agitation and extraction that loosens debris from the walls of air ducts and HVAC components. Steam air duct cleaning uses a wand to deliver a high temperature and high pressure steam in order to agitate the debris from the walls of air ducts drawn into the negative pressure by a vacuum. Truck mounted vacuum cleaning involves drawing a volume of air ranging from 10,000 to 15,000 cubic feet of air per minute, wherein a vacuum hose is attached from the truck connected to the trunk lines of the ventilation system, and air lines or rotary brushes are inserted into air vents to agitate debris to the collection point. The safest and most effective air duct cleaning method is point of contact methods, utilizing a portable HEPA filtered vacuum and an agitation device that simultaneously clean air ducts.Finding Similarities Between Companies and Life
