There is simply no getting around the fact that air duct cleaning are becoming more and more prevalent. Heck, just look at the number of cleaning companies that have popped up in the Dallas area over the last couple of years ago.
There was a time when there was only a handful. This certainly is no longer the case today. That being said, it is true that more and more homeowners are growing aware of the importance of cleaning your ducts and indoor air quality, but there are still plenty of them that are unsure about duct cleaning. And, this is because there is somewhat of a stigma surrounding the industry as well.
Being that we have been in the industry for a number of years, we can completely understand where you are coming from. This is why we would like to take the time to explain the entire cleaning process to our customers.

Verifying The Cleaning
The very first thing that you need to know is that not all duct systems need to be cleaned. Yes, there will come a time when that system does need to be cleaned, but that doesn’t mean it currently needs to be cleaned. This is just one of the reasons that there is such a stigma surrounding the process.
This is why we always dispatch out a highly trained inspector to assess the ducts and unit before scheduling a cleaning. We want to make sure that our customers are actually paying for something that they need and know how much they need to pay for air duct cleaning. Not only this but if your system does need to be cleaned, we will provide you with the proof.
Checking For Leaks
When our inspector is at the home he will not be just assessing the system for cleanliness. He will also be assessing the system for leaks and other problems. In fact, it might be a leak that is causing your current situation.
Our tech or inspector will evaluate the system and check for any leaks so that they can be repaired before the cleaning takes place. Cleaning a system with broken, loose, or cracked ducts are nothing more than throwing good money out the window. And, we want to make sure that this is something that our customers never do because that cash is just too hard to make these days.
Tapping Into The System
Once the cleaning is scheduled and the leaks are all taken care of our techs will be ready to get to work. The cleaning will start by tapping into the supply side of the ductwork. Our techs will tap into the system with a HEPA vacuum.
This allows us to place anywhere from 15,000 to 17,000 CFM of negative pressure on the system. Simply put, once our vacuum is connected to the system, your system will turn into a veritable vacuum cleaner, sucking up any loose dirt and debris.
Of course, it won’t get it all and this is where the next step of the process comes into play.
Blocking Off And Blowing Out The System
Once our vacuum is attached to the system our techs will be ready to move on to the next process. This step will involve coming into the home and blocking off all the supply vents, except for the one furthest away from the unit.
how is air duct cleaning done So much negativity on these comments? Sure there are some bad companies. Use BBB rated companies or other locally rated outfits. Not every company is bad.
Our techs are going to work their way from the unit to the unit starting with the vent located furthest away. This is basically the same way that you would tackle washing a wall. This process pretty much prevents you from going back over the work that you’ve already done. Once the vents are blocked off and the system is in negative pressure our tech will begin blowing out the vents.
This will be done with a portable air compressor and air hose. This just ensures that we knock loose any dirt or debris that might be stuck to the inside lining of the ducts.
Sometimes stuff gets stuck and it won’t come loose without a little encouragement. Our tech will continue doing this until they have covered every vent on the supply side. When finished, they should finish at the vent that is located close to the unit.
5 Tips For Summer Pest Control
Internal insulation provides better acoustical (noise) control. A flexible duct is a very low cost. These products are engineered specifically for use in ducts or as ducts themselves and are tested in accordance with standards established by Underwriters Laboratories (UL), the American Society for Testing and Materials (ASTM), and the National Fire Protection Association (NFPA). Many insulated duct systems have operated for years without supporting significant mold growth.
Keeping them reasonably clean and dry is generally adequate. However, there is substantial debate about whether porous insulation materials (e.g., fiberglass) are more prone to microbial contamination than bare sheet metal ducts. If enough dirt and moisture are permitted to enter the duct system, there may be no significant difference in the rate or extent of microbial growth in internally lined or bare sheet metal ducts. However, the treatment of mold contamination on bare sheet metal is much easier. Cleaning and treatment with an EPA-registered biocide are possible. Once fiberglass duct liner is contaminated with mold, cleaning is not sufficient to prevent re-growth and there are no EPA-registered biocides for the treatment of porous duct materials. EPA, NADCA, and NAIMA all recommend the replacement of wet or moldy fiber glass duct material.
how much is air duct cleaning Be sure you do not have any missing filters and that air cannot bypass filters through gaps around the filter holder.
Tapping Into The Return Side
That will pretty much be the entire process for the supply side of the system. However, it will now be time to tap into the return side. While there will only be one or two vents, it is highly likely that this site is going to be much dirtier.
This is because this is the side where the filter is located and the natural negative pressure. Pretty much, during normal operation, everything gets sucked through this side.
The process will pretty much just be the same. Our techs will tap into the duct with the vacuum, they will come in the home and block off vents if there are any to block off, and then they will just simply blow out the ducts until they are free of dirt and debris.
Cleaning the System
That is pretty much a duct cleaning in a nutshell. The only thing that will be left to do will be to tackle the system. That’s right, our techs actually clean the system as well.
We will clean the blower wheel as well as the coils. These are two common areas where mold and other bacteria can build. We will clean the components and area with a microbial solution just to eliminate the possibility of any mold growth for the next couple of months.
Once everything is cleaned our tech will button back up the system and ensure that everything is running as it was before we arrived.
