The Step-by-Step Process of Air Duct Cleaning

People often focus less on cleaning air ducts because they think HVAC maintenance is more crucial. However, they should understand that cleaning them is essential because it helps the HVAC system maintain efficient operations and improve indoor air quality. So, when you hire the cleaning service, here’s what you can expect.

Moving Furniture and Obstructions Out of the Way

Property owners should know that they must initially remove obstructions and furniture from the air duct openings. Experts recommend not placing anything near the duct opening.

Ensuring Pets and Children are Not in the Way

Sometimes, controlling pets and children becomes difficult because they are naughty. Not handling them might exaggerate difficulties during the cleaning procedure. So, to ensure everyone’s safety, children and pets should stay away from the working area.

Conducting an Initial Inspection

After removing all obstructions and children and pets not coming near the working area, the cleaning crew can start their job. The first step is to inspect the air ducts and ventilation system. The technicians have unique cameras and mirrors to look deep into the pipes. They will pinpoint the areas that are the dirtiest and require air duct cleaning services.

Cleaning Air Ducts Through Negative Pressure

In this method, the cleaners attach a high-powered vacuum cleaner to the air ducts and seal the edges. The machine creates negative pressure that pulls out debris and dust. A tip to enhance the negative pressure is to close air supply registries.

Removing the Settled Dust and Debris

Sometimes, debris, dirt, and dust settle on the air duct surface that a regular vacuum cleaner can’t remove. The cleaning contractors have special tools and equipment to remove stubborn dust and debris. The air duct cleaning tools used to clean the air ducts include:

  • Air compressors
  • Air whips
  • Rotary brushes
  • Negative air machines

Getting Rid of Pests and Small Animal Infestation

If the cleaning tea suspects the presence of small animal or pest infestations in the form of colonies or droppings, it should remove them. The team can use various products, such as repellents and traps, to free the air ducts from them.

Cleaning Other HVAC Components

Experts recommend cleaning various HVAC components, including drip pans, motor blowers, and coils, to ensure it improves overall efficiency. Cleaning these components will also ensure debris, contaminations, and dirt don’t accumulate in the air ducts and HVAC components.

Sealing the Holes and Access Points

Sometimes, the cleaning team creates holes and access points to reach certain areas of the air duct system. After cleaning and sanitizing, the technicians seal the holes so that air doesn’t leak through them.

Making the Final Inspection

In the second last step, the technicians will inspect the ventilation system and air ducts to ensure that every component is clean. The air duct cleaning experts will also check for wear and tear and signs of damage and examine if the air ducts are clean.

Test Running the HVAC System is Essential

The last step is to turn the HVAC system on to ensure the air ducts are clean and everything functions correctly. The technicians will check the proper airflow and strange noises and ensure that other components are intact. This step will ensure that cleaning is flourishing and you can use the HVAC system.


Property owners should learn about air duct cleaning to prepare them for what’s to come. The cleaning process includes moving furniture and obstructions out of the way.
