About Air Duct Cleaning: Understanding Air Duct Cleaning and Air Duct Cleaning Methods Air ducts are pathways where heated or cooled air to travel throughout a residential or commercial establishment, and it is always associated with your heating, ventilation and air conditioning (HVAC) system. Air ducts are commonly found in many homes, and its maintenance is often overlooked by tenants or homeowners. Apart 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 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. Some occupants are more sensitive to these contaminants than others, and those who have asthma and allergy are more susceptible to poor indoor air quality, so air duct cleaning can help address the problem. Air duct cleaning is defined as the cleaning of the cooling and heating system parts that include the supply and return air ducts and registers, heating and cooling coils, heat exchangers, grilles and diffuser, fan housing and motor, condensate drain pans or drip pans, and the air handling unit housing. It is recommended to get a professional’s help to check your entire 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. The various air duct cleaning methods used include 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. Experts recommend source removal as the best method of air duct cleaning, wherein the two key elements are mechanical agitation and extraction which loosens debris from the walls of air ducts and HVAC components. Steam air duct cleaning involves delivery of a high temperature and high pressure steam with the use of a wand, in order to agitate the debris from air ducts’ walls which are drawn into the negative pressure by a vacuum. Truck mounted vacuum cleaning process is 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 with the rotary brushes and air lines are inserted into air vents, agitating debris to the collection point. Point of contact methods are the most effective and safest method of air duct cleaning with its high velocity vacuum allowing a greater lift of debris and HEPA filters preventing cross contamination.Interesting Research on Experts – Things You Probably Never Knew
