Cleaning air ducts has a big impact on the cleanliness, health, and hygiene of a house. The longer you keep your air ducts unclean, the more dirt and dust they will collect, making your life difficult.

While we recommend hiring a professional air duct cleaning service, sometimes you can clean your ducts yourself. Especially when you regularly clean your ducts and there isn’t much work that needs to be done. 

For DIY air duct cleaning, you will need tools like a vacuum cleaner, a screwdriver, a soft bristle brush with a long handle, etc. Then, you have to remove the registers of the ducts and clean them. Next, you have to place the vacuum inside the duct, clean the debris with the help of the brush and suck them up with the vacuum. 

Let’s take a detailed look at how to clean air ducts yourself. 

The process of DIY cleaning air ducts

Air duct cleaning is a process that needs both time and effort. This is what, along with the sophisticated nature of the process, makes it quite difficult for the untrained to undertake. But sometimes, you might need to clean your air ducts yourself.

You might need to clean your ducts urgently. Or you might want to clean your ducts before the scheduled cleaning time just because you want to. 

If these are the cases, you should know how cleaning air ducts DIY is done. Here are the steps you will need to follow to clean your air ducts yourself. 

1. Getting all the necessary DIY air duct cleaning equipment

Before undertaking the cleaning procedure, you have to gather all the tools necessary for the job. If your air ducts are near the ceiling, you need to have a ladder. The other necessary DIY air duct cleaning tools are:

A. Screwdriver
B. Rags/Towels
C. Air filters
D. A long-handled brush with soft bristles
E. Vacuum cleaner
F. Safety equipment like masks, goggles, gloves, etc.

If you don’t have all these items in your home, you can either borrow them from a friend or rent them from a DIY air duct cleaning equipment rental.

2. Removing and cleaning the registers

The first thing you need to do is remove the registers of your air ducts. These trap a lot of dirt and debris when the air flows into them from the house and to the HVAC units via the ducts. Unscrew them with the screwdriver and then clean them one by one with a clean rag or towel. Once cleaned, set them aside. 

3. Agitating the debris

Agitating the debris air duct cleaning

Once you are done cleaning the registers, cover all the supply registers with paper towels, or clothes so that the debris doesn’t flow out through them. Next, turn the thermostat on which will turn the fan on, creating a negative pressure inside the ducts.

Then, using the long-handled brush, agitate the debris inside the ducts as much as you can. Remember not to put too much pressure on the brush, as it might damage your air ducts. 

4. Using the vacuum

Once you have agitated a sufficient amount of dirt and dust, you have to insert the hose of the vacuum cleaner inside the air ducts.

Then clean up all the loose dirt and debris with its help. Keep repeating this process until you don’t see any more debris inside your ducts. 

5. Changing air filters

Sometimes the air filters of your air ducts are too clogged up which prevents them from working properly. In that case, you need to replace them. Replace the old air filters with the new ones you have to improve the airflow and quality inside your home. 

6. Placing the registers back in their place

Once you are done cleaning your air ducts and changing the air filters of these ducts, you now have to finish up by placing the registers back in their place. Screw them back with the screwdriver you used before

Why you should avoid air duct cleaning DIY

As we have mentioned earlier, it is better not to clean your air ducts yourself. When you need to get your air ducts cleaned, you should hire professional air duct cleaning services.

This is because your air ducts are sometimes too delicate and fragile, depending on what they are made of. If you are not experienced in dealing with these types of air ducts, you might end up damaging your air ducts. This will end up costing you more money than you had saved while doing DIY air duct cleaning.
