Proper Duct Cleaning Methods Used By Professional Air Duct Cleaning Companies

This has been a topic of discussion for a long time. How do you successfully clean and restore a HVAC system back to its original condition or close to it. There are different methods that air duct cleaning companies have been using for years. Until recently there hasnt been a set standard for the industry. The National Air Duct Cleaners Association came up with the ACR. This has been a study done for years and they came up with a few methods of properly cleaning and inspecting the HVAC system. In this article I want to discuss direct source removal which is the NADCA approved method my company uses. The other method I want to discuss is a rotary brush with a vacuum system installed on it. Its name is rotobrush.

I own a company called CMR air duct cleaning. We have been doing duct cleaning in Raleigh NC for about 5 years. We use the direct source removal method. The way this method is done is by connecting a negative air machine to the system and cleaning the system from each vent as its under negative pressure.

The negative pressure will work together with positive pressure and agitation tools to get the system clean. The most important reason why have system under negative pressure is because we dont want to contaminate the indoor air. If you start going to all the vents in the house and start sticking brushes in the vent it loosens all the debris in there. So every time you pull the brush out whatever is on it goes in the house.

If you have the system under a constant vacuum these debris will be filtered outside through negative air machines. Thats why we do the method we do. The downfall about rotobrush is the system is not under a vacuum. So that means every time they pull out that spinning brush whatever is on it goes flying around your house. The other big draw back about that system is the vacuum inlet hole. Roto has a vacuum inlet the size of a nickel. Our Vacuum line is 10 inches in diameter. With that said I have sucked anything you can possibly think of out of duct work. Just a few thing for example dead animals, toys, food, and construction debris.

Now you cant possibly suck that stuff up through a hole the size of a nickel. Another down fall of that system is at times it can be to hard on flexible duct work. I have gone after certain companies and seen damage they have created by that spinning brush. Softer methods need to be taken like using compressed air. The compressed air is enough to agitate the duct but not sacrifice it. One of the other issues we have with the roto system is you cant properly sanitize the system. if you have mold in the system you have to be able to treat the entire system with a chemical.

The only way to do air duct cleaning is with negative pressure. You can clean all day long but you need chemicals to treat mold. I hope this articles clarifies a little bit about the proper air duct cleaning method to get the best results.

Thanks

Mold In Air Ducts Big Issue

Mold in the HVAC system is becoming a big issue in the Raleigh NC area. In the past couple of years Ive have seen a increase in this service.

The first step in resolving this issue starts with a complete scan and inspection of the system. I need to find the source of the problem and eliminate it. Once the source has been found then we can start the process of remediation the mold.

There are different types of duct work in houses. Houses that are usually 25 years or older, its common to find metal duct work. The newer houses usually have plastic corrugated flex line wrapped on the outside with insulation. These surfaces we can treat for mold and 9 times out of 10 get rid of it. The problem you can run into is the surfaces that have insulation.

We cant treat mold on a porous surface. I can treat the top of it but not the interior of it. So our post inspection we find these areas of concern and do evaluation of whether or not it needs cleaned or tore out. When in doubt tear it out. So once we get the source of our problem fixed we start the cleaning process. We use truck mount negative air machine. The negative air machine are connected to the system and then started. I first clean the entire system.

After the system is clean then we can start applying the chemical. We start are negative air machine and it puts your entire system under negative pressure. This is a very important step because we dont want to contaminate the indoor air. By having the system of negative this insures everything in the duct work will be filtered to our machine outside. Also by utilizing the system under negative we are able to sanitize the entire system. The anti-microbial we use comes in a liquid form. So what we do is we put in a machine called a fogger.

The fogger will break this liquid down to a fog. So as we have system under negative pressure we go to every vent in the house and start shooting that fog in to the vent. The positive pressure from the fogger and the negative pressure from our negative air machine will pull the fog through the vent. This will insure that entire system is covered in that anti-microbial. We leave are negative air machine running until the anti-microbial has reacted and dried. This also prevents the release of it in the indoor air. This the only way you can successfully coat the system with the chemical. You need to figure this, if you just take that fogger and shoot it down the duct its only going to go about 10 or 15 down or reach the first bend and it will stop. You have to have some kind of negative pressure working with the positive pressure to pull the chemical through the duct work. I work with multiple mold remediation companies in NC. This method is a proven one with scientific evidence to back it up.

The National Air Duct Cleaners Association has had multiple studys done on this and it works. CMR air duct cleaning are proud members of the association and follow their code of ethics.
