Improve Air Quality – Duct Inspections


air duct cleaning in Annapolis md

Throughout our more than 3 decades of providing comprehensive services performed by our chimney sweeps in Maryland, we realized how important the quality of the air in your home or business is. While we offer such a wide variety of services—from making a brick repair in Annapolis to repairing and selling wood stoves in Maryland—ensuring our valued customers are as healthy as possible in their homes is always one of our goals. If you have young children or an elderly person living in your home, unhealthy air may be the cause of any number of respiratory illnesses, including bronchitis, asthma, or allergies. The last thing you want your heat source to do is to compromise the immune system of someone in your family. Your household air should be as pristine and free of dust as possible, in order to promote better health for everyone who lives in your home.

Bacteria, dust and pollen in your ducts can make breathing in your own home difficult. Give our experienced technicians a call if you find yourself sneezing indoors or the area around air vents is dirtier than other areas in your home. We can run a comprehensive inspection on your home’s duct system to see if your ducts need to be cleaned.

  • Allergies & Breathing Problems

  • Dust Builds Up on Furniture Soon after Cleaning


Before and after cleaning of air duct

Conventional air duct systems consist of a supply and a return. The supply ducts of an HVAC system supplies heated or cooled air from the air handler to a main “trunk” line. The main trunk line carries the air to smaller “branch” lines which then distributes the air to various locations throughout the home.

Although air duct systems may vary a typical job would work as follows:

1) Turn the system on to make sure it is operating properly. Once determined that everything is operating fine, the system is turned off

2) The furnace filter is removed and card board will be inserted in the filter’s place to separate the supply and return sides of the system.

3) A very powerful portable unit is set up outside as close as possible to your furnace. (Some companies have the truck mounted vacuums which entails using a longer hose to reach inside the home therefore there is a great loss of static pressure and vacuum power which is why we use a “state of the art” portable unit. This unit moves 10 thousand cubic feet of air per minute)

4) Hoses are connected to both supply and return side of your duct work.

5) Once the connection is made our technician goes to each register and covers them with paper to seal them off. This will increase air velocity.

6) The vacuum system creates a strong suction that removes contaminates sucking them into a collector tank and the technician through the registers and returns uses an assortment of attachments to agitate and loosen contaminates inside the branch lines.

7) After cleaning the register and face plates are put back on. If your duct work layout allows a “Skipper Assembly” which is high pressured air is sent through the main trunk line.

8) After the system has been cleaned an EPA registered air duct sanitizer (EnviroCON®) will be applied. EnviroCON® is extremely effective and completely safe. While the system is still under negative pressure, the sanitizer is sprayed into each register with a hand-held atomizer or an air-driven sprayer.
