How Professionals Clean Your Ductwork

Posted on: 21 April 2019

Have you ever thought about how much dirt and debris is stuck inside your ductwork? There is likely years of accumulated dust inside there, which makes its way to the air each time you turn on your HVAC system. If you don't know the last time that your ducts were cleaned, it's a good idea to reach out to a local duct cleaning company to take care of this job for you. Without the right tools for the job, you are not going to be able to do it yourself. Here is how a professional actually cleans the ductwork in your home.

Setting Up

The process of cleaning your ductwork can sometimes create a mess, so a professional duct cleaning service is going to take precautions to cover things in your home. They'll set up drop cloths on the floor, cover furniture, and move items that are near the ducts that they are going to be accessing. That said, do not assume that your home is going to be covered in dust, since it's just a precautionary measure to make sure things are not dirty when they are done.

Sealing Off Registers

They next step is to go around your home and seal off the registers so that no dust escapes during the cleaning process. They may even remove the vent covers as well to give them a good cleaning.

Removing The Air Blower

Part of the cleaning process actually involves removing the air blower in your HVAC system so that they can bring in a negative air machine. This will attach in the place where the air blower was once located so that all of the dust can be sucked out of the ductwork.

Removing Debris Near Vents

The next step is to go around to each vent in your home and start removing all of the dirt and debris that they can find in the vents. The negative air machine will be sucking up anything that becomes loose and removing it from the system. Sometimes all it takes is a good scrubbing to get rid of the dust stuck to the surface near your vents. This can be done using a rotating brush that is attached to a cable, and forced through the ductwork at each vent.

Applying Sealant

Now that the ductwork is clean, the final step is to apply a sealant to the inside of the ductwork. This helps prevent new dust from sticking to the inside surface of the ductwork and prevent debris buildup in the future.

This is a general overview of the process required for cleaning your air ducts. For more info, reach out to an air duct cleaning company. 


Finding Incredible Flooring For Home

About a year ago, I realized that there were some serious problems with my home. In addition to feeling dated and looking a little dirty, I also hated the flow of the space. I talked with some remodeling contractors about fixing things up, and they pointed out how much of an improvement replacing the flooring would make. I chose a really nice charcoal gray plank flooring, and it made a huge difference. This blog is all about finding incredible flooring for your home and knowing what to avoid along the way.
