DustBusters Duct Cleaning Specialists

The removal of such contaminants from the residential or commercial HVAC system should be regarded as one component of an overall strategy to improve indoor air quality. Heating, ventilation, and air conditioning (HVAC) systems have been shown to collect a variety of contaminants such as mold, fungi, bacteria, and very small particles of dust that have the potential to affect general health. Ask us about other components for improving your indoor air quality.  

A visual assessment of the HVAC system before and after cleaning is the best method to tell if the cleaning was successful. The system shouldn't be deemed clean during the visual examination if any dust or dirt are visible. A professional cleaning company should be able to provide you with better access to system components and potentially the use of specialist examination gear, such as a video camera, even though you can undertake your own visual check utilizing a flashlight and mirror. Additionally, adhering to the Homeowner's Guide to Air Duct Cleaning will also help in verifying a clean air duct system.  

Frequency of cleaning depends on several factors, not the least of which is the preference of the owner. Here are some additional thoughts to consider for more frequent cleaning:

Smokers in the home or commercial building

Pets that shed high amounts of hair and dander

Water contamination or damage to the home or HVAC system

Individuals with allergies or asthma who might benefit from a reduction The number of indoor air pollutants in the home’s or building's HVAC system

After home renovations or building remodeling

Prior to occupancy of a new home or moving into a new building

Using source removal cleaning techniques is the most efficient approach to cleaning ventilation and air ducts. To accomplish this, a contractor or air duct cleaning company must utilize a specific, strong vacuum to apply negative pressure to the system. Devices are put into the ducts to remove any debris that may be attached to internal walls and surfaces as the vacuum draws air through the system. By disturbing the debris, the vacuum can then remove the debris from the home or commercial air duct system.  

To treat microbiological contamination like fungi (mold), viruses, or bacteria, some air duct companies apply antimicrobial chemicals to the interior surface of the air ducts. The system should be completely cleansed before using any antimicrobial agents. Any antimicrobial treatment you use in your system must be approved for use in HVAC systems by the US Environmental Protection Agency. An extra service that is not typically provided as part of an air duct cleaning procedure is the application of antibacterial agents.
