Duct Cleaning: All You Need To Know

Whether or not you decide to clean the air ducts in your home, preventing water and dirt from entering your system is the most effective way to prevent contamination (see How to Prevent Air Duct Contamination). Duct cleaning can cause indoor air problems if service providers don’t follow proper duct cleaning procedures. There is little evidence that cleaning the air ducts alone increases the efficiency of the system. Duct cleaning will eliminate the build-up of allergens in the ductwork and prevent the spread of these allergens in your home through the forced ventilation system. We would recommend hiring one of the many duct cleaning companies that are out there to do this for you.

HVAC Systems

In fact, since the only time you need to clean the ducts is when they are dirty, it follows that if you need to clean the ducts, then you must clean the entire HVAC system that comes into contact with the air passing through the ducts. A clean duct system allows the entire HVAC system to operate more efficiently, reducing heating and cooling bills, extending equipment life, and providing cleaner, healthier air to the home. Cleaning these components, along with cleaning or replacing the filter, will improve the air quality in your home, extend the lifespan, and increase the efficiency of your HVAC system.

Change the air filter regularly

Since your air conditioning system is designed to use an air filter to clean the air, the most obvious thing you can do is to change the filter regularly. Your air conditioner already has a built-in cleaning system The air conditioner system already has a built-in cleaning system called an air filter. Duct Cleaning Services Can Actually Damage Your Ducts Because air conditioners rely on air filters to clean the air, and there’s no evidence the ducts need cleaning, HVAC manufacturers don’t design clean ducts. It might sound like a logical maintenance task, but cleaning the ducts in your home’s HVAC system might not be as good as it sounds.

Sealing

Duct cleaning service providers may also recommend the use of a “sealer” to prevent dust and dirt particles from entering the air or sealing air leaks. A duct cleaning service provider may tell you that they need to use a chemical fungicide inside the duct to kill germs (bacteria) and fungi (mold) and prevent future biological growth.

Clean ducts mean less dirt in the home and in the air because ducts are often a source and pathway for dust and biological contaminants. This is also about ensuring that all pipes and vents in your home or commercial building, such as air ducts, drying ducts, and even garbage chutes, are free of dirt, harmful debris, and deposits. Drying ducts are often overlooked when it comes to keeping the vents in your home or commercial property clean.

 

The methods used by accredited contractors are called NADCA removal methods and include cleaning the air ducts manually and with compressed air tools, while a vacuum collecting device removes any displaced dust and debris. The HEPA-AIRE method allows our technicians to reach and thoroughly clean the entire duct system with minimal noise and interruptions. These procedures determine how to properly clean ducts, registers, filters, plenums, evaporator coils, and air handling units—nearly every component of a forced air HVAC system—and the results will be obvious.

In most cases, the dust that enters through the air filter into the duct system is minimal and does not cause a noticeable reduction in air quality. As one study shows, most of the dust will stick to the surface of the duct and will no longer enter your home. Have your contractor use a camera to check for excessive dust inside the ducts and show you evidence before they start cleaning.

At the same time, installing insulation on the outside of ducts whenever possible, keeping existing fiber insulation clean and dry, and properly maintaining and replacing system filters can help reduce the need to clean duct insulation in the first place.
