Air duct cleaning process

Since cleaning air ducts has become very important in maintaining the cleanliness and hygiene of homes, their demand has also increased. This has led to various fraudulent service providers scamming people for thousands of dollars.

One way you can protect yourself from getting scammed is by having a good idea about the air duct cleaning process. 

At first, professionals will perform a visual inspection of your air ducts to see how much work they have to do.

They will then create a negative pressure inside the ducts, which will prevent dirt from flowing out.

They will then agitate the debris and use vacuum cleaners to clean them up. Finally, the process will be capped off by cleaning the HVAC units and repairing any damages in the ducts. 

Let’s take a look at all these steps in detail. 

Air duct cleaning process: Explained

Apart from preventing getting scammed, people should also know about how air ducts are cleaned.

This will inform them of why hiring a professional air duct cleaning company is important.

Since the procedure is a detailed and time-consuming one, knowing how cleaning air ducts works will discourage homeowners from trying to clean their air ducts and damaging them.

So, here are the steps a professional air duct cleaning service follows to clean the air ducts in your home.

1. Inspecting visually

Performing a visual inspection of your air ducts is the first thing professionals will do.

This will help them see how dirty your ducts are, and how much work they will have to do. It will also help them see if there is any damage or leaks in the air ducts in your home. 

2. Creating negative pressure in the ducts

When cleaning air ducts, the professionals will create a negative pressure inside the ducts, which will ensure the debris doesn’t fly off into your room through supply registers.

They do this by using professional-grade vacuum cleaners. The hose of the vacuum cleaners will be entered into your ducts by cutting a small hole in them.

The holes will be sealed once the cleaning procedure is done, so you won’t need to worry. The air vents will also be sealed shut by adhesive seals to prevent a mess from being created. 

3. Loosening the dirt

Once the hose is in place, expert air duct cleaners will start to loosen the dirt by agitating it.

This is one of the best ways to tell if someone is amateur or not. While untrained cleaners will use sticks or regular brushes, sanitizers, and air compressors to agitate the dirt, professionals will use specialized tools to do so.

These tools include rotating brushes, traditional vacuums, etc. 

4. Cleaning up the debris

Once enough dirt has been loosened, the experts will clean them up using their high-powered vacuum cleaners.

These vacuums are extremely efficient in cleaning every bit of loose dirt and debris from the ducts.

These can sometimes be quite loud, so you need to take the necessary steps to protect your children, elders, and pets. 

5. Finishing up

Once all the debris has been cleaned up by the vacuum cleaners, professional air duct cleaners will look for any leaks and damages in the ducts.

If there are any, they will repair those. They will also clean your HVAC units so that the airflow becomes clean and healthy.
