How to Clean Your Air Ducts?

Jul 28

Cleansing your air ducts can improve the air quality of your home. Air duct cleaning can also help homeowners save money on their energy bills and improve the cooling system's efficiency. Do you know what it takes to properly clean your vents and air ducts without causing damage?

Tools Required for AC Duct Cleaning

To clean your air ducts, you'll need a vacuum, leaf blower, and power drill. A respirator is needed to keep from breathing in the elements. Before you start anything, make sure you turn off the furnace's power.

Vacuum: Before you buy a vacuum to clean your air conditioner vents, make sure you have a Shop-Vac. The housing may be damaged by sharp elements such as screws, which tend to settle at the bottom. It is recommended that you use a heavy-duty or old vacuum to complete this project.

Leaf blower: After vacuuming thoroughly to your best ability, you can use the leaf blower to remove any remaining dust particles from the AC vents. The material that covers your ducts will be visible without any film or opacity when you blow the air hard enough. This is why you should use an electric blower and not a gas-powered one.

Power Drill If the air ducts inside your home are made of steel, then you will need to enter them to clean them properly. You will need to drill a hole of five inches in the steel ducts using a core drill bit. You might need to drill multiple holes if your core bit is smaller than five inches in diameter. This will allow you to insert your vacuum hose into the ducts. If you aren't living in a new home, it is possible that  HVAC vent cleaning was done by the previous owners. If that is the case, the air conditioner cleaning company had already drilled holes and covered them in steel plates. Find the plate covers, remove them and clean those ducts.

An Old Pillow: While the pillow doesn't have to be worn out, it is necessary to use it as a stopper before the air enters the handler. You can also use extra insulation. All elements must be kept out of the air-cooling system.

N95 Respirator A NIOSH-approved N95 respiratory mask should be worn when cleaning home air ducts. This will ensure that the person is not inhaling any harmful substances. It is unknown how old the ducts and the materials used in building the home are. Asbestos is the last thing you want to inhale. The NIOSH-approved N95 respirator will protect you.

How To Clean Ducts DIY

Once you have all your tools for cleaning the air ducts, it's time to get started on cleaning the house. Start by taking out your screwdriver to remove the return vents. After vacuuming the outside plate, take your screwdriver and start sucking up any dust and debris from the duct. You might be able to find something you have been searching for, such as a set of keys. No matter if you find something, the exterior of the vents must be cleaned thoroughly.

After all, vents are cleaned, it is time to clean deep within the air ducts. Access the main HVAC ductwork. These air vents are often located in tight spaces such as a crawlspace or basement. Hire a local trusted air duct cleaning company if you don't want to do the dirty work. Once you've inspected the ductwork, you can now access it. You can either create a new hole using a core drill or remove the steel plate that covered a hole you have made previously. A single hole won't suffice. The size of your air-cooling system determines how many holes you'll need to clean your vents. You will stuff the vent with a pillow at the point where the duct connects to the air blower.

Properly Covering Supply Registers

This stage is the most important in the entire duct cleaning process. It will make all of the work you have done so far useless and also cause havoc to your home's air quality. To block the push vent, place a piece of parchment paper or a paper towel on the vents. Although this can save money, it might not be able to hold up if the vents are subjected to extreme pressure. The vents can be either held or blown out, allowing dust and debris to return to the home. Temporary register sealing tape is the best way to ensure that register vents do not allow dust and debris to enter the home. After you have done all of the above, sealing all vent openings with reliable tape will be worthwhile.

Cleaning Up The Remaining Dust From The Air Vents

After we have cleaned out all dust from the vents' perimeters, it is time to use the leaf blower to remove any remaining dust. The electric leaf blower should be plugged into the outlet next to the air handler. After that, the leaf blower should be pointed inside the air duct through the perforated hole. The electric leaf blower will release all dust and debris that is trapped in the vents when you turn it on. You should blow the dust out of any hole you make in the venting. After you have done this for a few minutes, you can use the ShopVac vacuum to remove any remaining dust. To reach areas that the vacuum cannot reach, you can use a long duster with flexible heads.


You cleaned the inside of your ducts yourself. Place a metal plate on top of all the holes in the vents, and seal them with foil mastic tape. You can then remove the covers and vacuum up any leaves that may have fallen from your leaf blower. Now you can turn on your air-cooling unit and allow it to run as normal. An air duct cleaning specialist should be contacted if you notice dust in your home. Your ducts still need to be cleaned, even though you have done a lot of work.
