MECHANICAL FACT
A conventional Heating/Cooling system consists of 2 duct systems (Networks):
1. A SUPPLY system of ducts to carry (or supply) the heated air from the furnace to various parts of the house/building.
2. A RETURN system of ducts to bring back (return) the “cold” air to the furnace to be reheated.
These two systems MUST be “ZONED” or separated prior to the cleaning process in order to clean both systems
STEP 1: POWER VACUUM: Professional duty providing 4000-6000 Cfm.
An access hole is cut into the Supply Plenum where the Power Vacuum is to be attached. When in operation, dust/debris is dislodged from the ducts and pulled into the unit by a 12 inch (diameter) flex hose.
MUST: High-efficiency multi-stage filtration system must be used to assure “hospital operating room” air is exhausted back into the house.
Multi-stage HEPA filters.
STEP 2: COMPRESSOR STAGE: Industrial grade professional unit to deliver no less than 180 P.S.I.
Compressed air is applied to the entire system through each register (vent) while the Power Vacuum is in operation. This pushes the dust/debris into the main duct and into the collection system.
MUST: Compressor must be left outside the house during operation and non-marking air hoses to be used inside the house.
STEP 3: MECHANICAL AGITATION: A very important final step, disregarded by many duct cleaners.
Rubber whips and/or soft brushes are used to dislodge (agitate) any debris “stuck “on the inside of the ducts.
MUST: Different whips/brushes are designed for different duct materials (flex ducts in newer homes or metal ducts in older homes). Only an experienced duct cleaner can use the proper assembly and combination to achieve the best results.
STEPS 1, 2 and 3 are repeated to clean and decontaminate the RETURN “(cold)” duct system.
