Air Duct Cleaning: What And How It Is Done What should be done? When seeking to hire an air duct cleaning company, it is important to find one with high ratings and experience. This will ensure that the job would be done right in the first go. Here is what duct cleaning providers should do as part of their suite of services:
Open access ports that will allow the complete system to be cleaned after being inspected Review the system before starting the cleaning to make sure that there are no loose materials in the heating, ventilation and air conditioning (HVAC) system that contain asbestos Use High-Efficiency Particle Air or HEPA vacuuming equipment in case the vacuum exhausts are situated inside your house Shield the furnishings and carpets while the cleaning is going on Use controlled brushing for duct surfaces with some contact vacuum cleaning Use brushes with only soft bristles Take special precautions to protect the duct work Follow the industrial standards for duct cleaning
How it should be done Ask the company if their duct cleaning professionals will perform these typically good practices:
Would they keep the ducts getting cleaned under negative pressure during the process of cleaning? This will minimize the dust and dirt discharge. Would they avoid unnecessary cutting of holes in the duct and duct liner?
Is the collection equipment with the vacuum located outside of the real estate? If inside, do they offer HEPA filtration for the discharge? Is the vacuum combined with brushes to lift up the settled materials from the interior of the ducts? Would they avoid the use of sealants to cover up interior-contaminated ductwork? Will they remove (instead of cleaning) the bio-contaminated porous materials or waterdamaged materials?
