What Is Air Duct Cleaning?

Reading Time: 3 minutes

Just like washing your home’s curtains every couple of months, it’s important to clean your air ducts every few years. Regular duct cleaning improves your indoor air quality, helps control allergen and irritant levels, and helps your HVAC system to run efficiently.

Do you want to know exactly what air duct cleaning is and how it works, read on to learn all about the duct cleaning process.

Why Do I Need To Schedule Air Duct Cleaning?

Professional air duct cleaning removes dust, allergens, pet hair, bacteria, and other particles from your HVAC system. If these particles are not removed, they can end up circulating in the air you breathe. Air duct cleaning is an essential part of air duct maintenance.

It is recommended that you have your air ducts cleaned every three to five years. If you or a family member have allergies, asthma, smoke, or own pets, it can be worth having them cleaned more frequently.

What Equipment Does An Air Duct Technician Use?

Air duct technicians use several equipment pieces to ensure they clean every inch of your air duct system.

When performing an inspection, your technician can use a small mirror, a periscope, or CCTV cameras with flexible cables. To clean the ducts, they use a negative pressure vacuum, rotating brushes, regular brushes, and agitation devices.

Steps During Professional Air Duct Cleaning

Air duct cleaning is a simple process, but it requires specialized equipment and a trained technician.

The cleaning process can be divided into 5 steps:

Step 1. Pre-inspection

During the pre-inspection, your air duct technician looks at your air duct system and decides what cleaning process or technique is best. They do this by examining the system from all access points and accessing the overall condition of your ducts.

If the technician notices any issues with the duct system, they can perform repairs. Common issues include leaks and kinks.

Step 2. Create Negative Pressure

Air duct technicians use specialized vacuums called negative pressure vacuums during the cleaning process. These vacuums are large and portable. A negative pressure vacuum makes the pressure inside your air ducts lower than the atmospheric pressure. This pulls out contaminants like dust, bacteria, and allergens.

Your technician will cut an access hole into a section of your air duct, insert the vacuum, and tightly seal the area where they join. They will then seal every other access point to your air ducts to maximize the negative air pressure. Finally, they’ll switch the vacuum on; ready to collect any loose particles inside your air ducts.

Step 3. Agitate Dust

Once the vacuum is hooked up and running, the technician will open each access point one at a time and use specialized equipment to shake lose any debris clinging to the walls of the system. Common equipment pieces include rotating brushes and compressed agitation air tools.

Step 4. Remove Debris

Once the ducts are clean, the technician will move on and clean the other system components, such as the drain pan, evaporator coil, and air blower motor. They will also switch out the air filters to extend the lifespan of your air duct system.

Step 4. Final Inspection

Once they’ve completed the duct cleaning process, your technician will take a final look through the system to ensure every section has been covered and cleaned thoroughly.
