How Does Air Duct Cleaning Work

It is vital to regularly have inspections done on your HVAC system since your air ducts need to be cleaned from time to time. The best way is having a skilled and licensed worker or company to do this for you, as they have the expertise. In case your ducts have not been cleaned by a pro before, it is about time you pick a reputable and trustworthy company to inspect your pipes. The National Air Duct Cleaners Association should at least certify the right company.

A lot of homeowners search for air duct cleaning companies with upgraded equipment and a dedicated team. In 2017, only approximately 5 percent of air duct cleaning companies in Northwest and Washington had efficiency and performance exceptional enough to receive the ‘Angie’s List Super Service Award’

How Does Duct Cleaning Work?

When expecting an inspection, it is reasonable to ask yourself, “How does air duct cleaning work?” worry no more, as below is a step by step detailed guide on how the whole process takes place. These are the same steps that technicians follow when they come to your home, as NADCA standards state. All qualified contractors should use some tools and equipment for the best result. These access tools include;

  • Drills
  • Saws
  • Chemical sanitizers
  • Vacuums
  • Brushes
  • Imaging devices

1. Inspection

This is the first step because it is the determinant of if and how your air ducts will be cleaned. You do not need an expert for this as it is straightforward, but it is safer if you hire one. The difference is that technicians have imaging devices and hand tools, which make leaks and kinks noticeable. Some drilling might happen, but a pro will leave your ducts in good condition. This step is helpful as you can see the dirt and stuffy build-up since the last cleaning session.

Access tools are necessary for technicians to get to innermost parts of the duct. When the inside of the duct is inspected, the experts are able to determine if the devices are needed or not. Cameras, mirrors, periscopes, and CCTVs are among the most used imaging tools to inspect an air duct. The equipment is usually designed for pipes; therefore, it provides impressive results.

2. Vacuuming

A superior and efficient vacuum specialized for the process is essential. Most technicians use a portable vacuum system, but severe cases or commercial ones use spaces mounted on trucks. Both types work amazingly -the quality and method of use are what matters.

By applying negative pressure, the technician hooks the equipment to the foundation of your HVAC system, drills a hole, and insert the hose. Successively, every register in your home is sealed to increase the vacuum’s performance. After the expert does this, they turn on the air duct cleaner to start the cleaning process.

3. Brushing and extra vacuuming

Inexperienced or unlicensed contractors/technicians frequently clean your ducts once using the vacuum. However, a professional should understand that one suction is not enough, and that is where the brushes come in. When an expert follows the rules dictated by NADCA, they naturally spend a more extended period cleaning each register.

The brushes rotate and get inside the air ducts’ tubes. These are the places a vacuum hose cannot reach. Also, a skilled worker will pair the rotating brushes with chemical disinfectants for extra sanitation. Also, mold is a common problem, and you might have spotted the contaminant in your air duct. Experts use chemicals when cleaning your pipes to get rid of potential and current waste products safely.

4. Cleaning the system

Lastly, after all the dirt has been sucked from your duct system, the technician will clean the blower motor, drain pan, evaporator coil, heating, and cooling unit, and seal any access holes. The main reason behind this step is because a well-sanitized HVAC system means fresh and stable air rotation in your home. When the process is done, you will have to maintain your air ducts and call for a constant inspection.
