Many homeowners do not know what goes on during an air duct cleaning process. It is important to understand the process if you may need to assess the final results and determine if the cleaners did a good job. Find out below exactly what does in during air duct cleaning.
Before the cleaners begin air duct cleaning, you have to play your part by securing your carpets and household furnishings. Most cleaners request that you remove your car out of the garage or driveway. The reason is they use large equipment such as hoses and pipes hooked from their trucks to your furnace.
You will be required to give a brief overview of the house so that the cleaners can locate all the supply and return air ducts. The power to the furnace and any other attached device is then shut off. Your service provider will then open the access doors for the whole system to be cleaned and inspected.
The system is then inspected before cleaning to ensure no asbestos-containing materials in the cooling and heating system. Such materials need specialized procedures and are to be handled by expert contractors.
The blowers are then removed and disassembled to be cleaned with soap and water. Your service provider hooks the vacuum line to your furnace to the return airside. The grill is then removed and washed as well. Depending on your duct type, the service provider may then run a reverse air duct cleaning tool to agitate the debris and dirt in the system. The vacuum equipment then traps the dirt and debris. The vacuum equipment must exhaust outside your premises. Otherwise, the service provider should use a high-efficiency particle air vacuuming device if the vacuum is inside.
After the return ducts are thoroughly cleaned, the same is done in the opposite direction. A whip system is then used to clean the supply duct’s plenum and the trunk line. Then the blower compartment of the furnace is cleaned thoroughly. If a conditioning coil is installed, both sides are blown out with compressed air to loosen debris and dirt. It is then sprayed down using a self-cleaning, biodegradable coil cleaner agent.
At this point, the air duct cleaning process is done, and the service provider is obligated to ensure they have abided by NACDA’s air duct cleaning standards. They also ought to have followed NAIMA’s advised practices for air ducts lined or constructed from fiberglass.
Your service provider should use soft-bristled brushes for sheet metal ducts lined with fiberglass and fiberglass duct boards. Before returning the blower, the cleaner should brush it down and clean any dirt stuck on it. A degreaser is then used to wipe it down, giving it a new and polished look. The furnace is then put back together, and the proper operation of the system is ensured.
Air duct cleaning is almost a complex process to explain. However, with this simplified guide, you will have a simplified and informed understanding of what happens during duct cleaning.
