We use a dual process cleaning method, point of contact and negative air to ensure the removal of all debris build up from the vents.
A vacuum hose is sent from the opening of the vent to the trunk line/furnace snaking through the system removing any loose dirt, dust, or debris. This is followed by a high pressure air whip sweeping the side walls free of any remaining dust, which is then removed with the vacuum hose that is still in the trunk line/furnace. The same process is used for the cold air returns.
AB Richards fit me in emergently. Eric and Kris were top-notch. They came in and knew exactly what they were doing and did the work efficiently. They got a ton of crud out of my dryer vent and duct work. Kris fixed a problem he found with the dryer. And Eric fixed a problem that could have been fatal. The previous owner had stuffed insulation in the space where carbon monoxide is supposed to disperse. We felt so much better and breathed so much better after having this work done. Amazing results.
They cleaned our air ducts, sanitized the ducts to prevent mold and germs from growing, cleaned the furnace from blower motor to the exhaust flue to make it more efficient.
