Remember; think about your air system as the lungs of your home. Then consider the type of company that you want to handle your home’s lungs and your indoor air quality within your home. Have the complete air system periodically inspected for contaminated duct work and have it properly maintained so your Heating and Air System can provide your family with good air quality for years to come.

More particles could be broken up and released into your home or your HVAC system could be damaged.
There is some disagreement within the industry about the best method for cleaning air ducts. The two schools of thought are the “negative air” approach and the rotary brush and vacuum approach. We believe that both air duct cleaning methods can achieve great results in most situations when performed properly by competent technicians. However, our focus has always been on high quality residential service. The type of residential duct work commonly used in homes in the South poses unique challenges to duct cleaners because it is soft, flexible, and does not go in straight lines. Firms using the negative air approach are especially challenged by this type of duct work, as that process was originally designed to work well on the rigid metal duct work commonly found in the North and in large commercial buildings. The tools used to agitate the duct work in negative air cleaning are very difficult to get all the way into your duct work and can damage the lining of the ducts we find in most residences in the greater Jacksonville area.
On the other hand there are a lot more duct cleaning business that will appropriately clean the air system and duct and make use of industrial damaging duct cleaning vacuums with a minimum of 2,000 CFMs of vacuum power and use correct agitating tools to move the contaminants within the duct to be recorded with HEPA filters and consisted of by the duct cleaning vacuum devices.
