The Air Duct Cleaning Methods

Have you recently been on the Internet searching for air duct cleaning near me? Maybe you have been receiving a lot of home air duct cleaning ads in the mail and are just wondering what all the hype is about.

Well, it is a well known and proven fact that air duct cleanings services can improve the overall indoor air quality as well as increase the efficiency of the unit. However, what you need to know is that not all air duct cleaning companies are created equal.

This is why when you are searching for duct cleaning near me it is more important than ever to understand how the air duct cleaning process works. There are several different methods in which the ducts can be cleaned, but the best companies will follow the method described below.

Identifying Leaks

The first thing you need to know about air vent cleaning companies is that they should send out an inspector before the duct cleaning is scheduled. Never do business with a company that just books the cleaning without sending out an inspector.

The inspector not only makes sure that the ducts need to be cleaned, but he will identify possible leaks within the system. If your duct system is leaky and you get a cleaning without sealing the leaks, you aren't doing yourself any favors.

This would be like vacuuming your carpet without using a vacuum bag to capture the dirt. If the system isn't properly sealed the cleaning will not only be ineffective, but it will cause your energy bill to skyrocket.

Sealing Leaks And Attaching To The System

Once the vent cleaners arrive at the home they will first go ahead and repair the leaks that were identified by the inspector. Once all the leaks are repaired they are then going to attach into the system with a HEPA vacuum.

This is not just an ordinary vacuum cleaner as it will be about four times the size of a modern vacuum cleaner and it will contain a HEPA filter. The purpose of this vacuum cleaner is to place negative pressure on the ducts.

This means that when contaminants are broken loose they are going to be sucked up by this vacuum cleaner. They will first attach to the supply side of the system and they attach as close to the HVAC unit as possible.

Blocking Off The Vents In The Home

Once the supply side of the system is placed under a negative pressure the vent cleaning company is now going to enter the home. The air duct cleaners will block off the supply vents will a piece of plastic or some other material.

They will block off all the vents except for the one furthest away from the HVAC unit. The basic idea of the whole process is that they are going to start at the end of the system and knock the contaminants and debris loose working their way toward the unit. Blocking off these vents also helps increase the negative pressure that is being placed on the system.

Air Duct Cleaning Services Knocking Loose Debris and Contaminants

Once the vents are blocked off and the HEPA vacuum is pulling a negative pressure on the home the tech will be ready to knock loose the debris and dust. There are two different ways that they can do this and it really depends on the type of ductwork that you have.

If you have all hard pipe then the techs will be able to use rotary air bushes brushes. These brushes look like something that you would find inside an automatic car wash just on a small level. The brushes in combination with the high-pressure air will knock loose as much dirt and debris as possible while it is being sucked back towards the HEPA vacuum.

Now, if you have flex duct, which most systems will the techs will not be able to use these brushes because they will likely damage the duct and rip it. Instead, they will have to use air pressure alone. Keep in mind that they do have special nozzles that attack every surface of the duct just like the brushes would.

Once the vent it cleaned it will be blocked off and the techs will move to the next vent that is furthest away from the unit. They will work in this manner until they have cleared every vent in the home that is attached to the system that they are cleaning.

Cleaning The Registers And Ducts

After the air duct cleaning company has cleaned the supply side of the ducts they will clean the supply registers and inside the vents with microbial chemicals. These chemicals are specifically designed to kill mold spores and other bacteria.

Such chemicals are not harmful to pets or humans so you can remain the home while the cleaning is taking place. Keep in mind that some air duct cleaning companies might clean the vents and registers as they go. This means they might break loose the contaminants, clean the register, clean the vent, and then move on to the next vent.

Cleaning The Return Side Of The System

When the entire supply side of the system is clean the air duct cleaning company will seal the supply side of the duct that they tapped into and move onto the return side. Once again, they will tie in as close to the unit as possible.

They will also come in and block off any return with plastic, but most systems are only going to have one return so this might not be necessary. The return vents will be cleaned in the same manner as the supply vents.

Cleaning The HVAC System

After both the supply and return sides of the system are cleaned the techs will them move onto the unit itself. They will clean the evaporator coil as well as the blower wheel. They will clean these components with microbial chemicals to kill any potential mold spores or other bacteria. At this point, the cleaning will be done.
