STEP CLEANING PROCESS
complete HVAC unit/system is turned off.
furnace cover(s) and air filter(s) are removed. The furnace,
blower motor, and air filter(s) are then inspected for cleanliness.
If necessary, the service technician will recommend whether
these components should be cleaned or not and the services will
be offered. If the air filter(s) needs to be replaced the filter
size will be measured and noted and may be purchased at the
customers' discretion. Efficient, high-quality filtration is
key to maintaining your HVAC equipment and keeping your duct
technician then examines the house and the main ductwork in
the basement to determine how many zones there are. The zones
for residencies are broken down as follows: single, double,
or triple zone.
access hole 6 inches in diameter is cut into each supply plenum
(depending on how many zones) and into the cold air return.
The technician will choose where to cut these access holes according
to experience and convenience/accessibility to the structure
of the ductwork for that specific job.
one, all supply vent covers/registers are closed which increases
the air movement in the ducts. The one open supply register
allows the air to safely flow backward through the air duct
system without creating adverse negative pressure.
return covers are prepared for removal.
the vacuum hose is connected to the return access hole.
Super-Vac Truck-mounted system is then turned on to create negative
pressure within the return ductwork.
forward and reverse air blast assemblies, all return registers,
branches, and main return ducts are air-washed and cleaned.
Agitation is a method used which causes dust and debris to be
quickly caught up in the air movement and is vacuumed out of
the system into the vast holding tank mounted to the truck.
vacuum hose is then situated where the return duct meets the
furnace to ensure any dust/debris that has fallen hasn't been
missed and everything is collected.
vacuum hose is then connected to the access hole(s) made in
the supply plenum(s) creating negative pressure within the supply
Starting from the vent opening furthest away from the furnace,
each branch line is air-washed and cleaned using only forward
air blast assemblies. This process is then repeated at each
supply vent opening as the technician makes his way from the
top floor down to the bottom floor/basement. Each register will
be opened and then closed again once cleaned.
Once all supply branch lines are cleaned, the technician will
cut one-inch holes every couple of feet in the main supply ductwork
that is exposed to the eye. Using forward and
reverse air blast assemblies, the main supply ductwork is then
air-washed and cleaned to ensure all dust/debris has been removed
and collected out of the whole duct system.
any other services are requested (i.e. Furnace cleaning, blower
& coil cleaning, etc.) they will be done in-between cleaning
the return and the supply or after the
complete duct system has been cleaned
The Super-Vac Truck-mounted system is then turned off.
All supply vent covers/registers are opened.
The HVAC unit/system is then turned on and inspected for proper
If the customer has requested sanitization, a product called
Benefect is sprayed/fogged throughout the air duct system using
the access holes that were made. A combination between air pressure
and the hot air supply now flowing pushes the sanitizer throughout
the whole air duct system. This product is a disinfectant and
a fungicide and immediately kills any bacteria, mold/mildew,
fungal spores, and other contaminants that may be left in the
system. This product will air-dry and evaporate leaving no chemical
All one-inch holes are plugged and sealed with soft-plastic
plugs standard to the duct cleaning industry. All access holes
are then securely closed with proper gauge
sheet metal plates cut to size. Each metal plate is secured
to the duct using sheet metal screws and the edges are sealed
with aluminum foil tape ensuring a complete, proper seal.
