Purpose of this
page: To give you simple, easy to understand
information on our
Residential Air Duct Cleaning services which are
designed to improve your home's
indoor air quality.
Information:
Machado Environmental has performed over 25,000 air movement system
cleanings
since 1983. We provide the most thorough residential air duct cleaning
services.
What we do,
why and how much
We
thoroughly clean central heating and cooling systems in homes
throughout Southern California.
We use the
"source removal" method of cleaning. This means that all the
inner surfaces of the heating and air conditioning system
exposed to the air stream are thoroughly brushed, vacuumed, and
even washed in some cases. First we
remove all the vent grilles from the walls, ceiling, or floor.
They are taken outside and washed.
The blower housing is removed from the furnace and the blower
wheel is then disassembled from the motor, washed (scrubbed if
necessary), then reinstalled. The blower housing is also
cleaned.
We wash
(not just blow off) the evaporator (cooling) coils, clean the
heat exchanger, and thoroughly brush and vacuum the inside
surfaces of the air-handling unit (furnace).
Any fiberglass insulation exposed to the air stream is coated
with a special encapsulant, which prevents fibers from coming
loose and blowing into occupied spaces.
A large, high-power HEPA-filtered vacuum collector is attached
to the central duct system, which puts the whole system under a
negative air vacuum. This means that the airflow is now reversed
and air is being sucked back in through the vent openings
instead of being blown out.
All the vent openings are covered up, except for the one through
which the cleaning is being done. One by one, the duct runs are
all cleaned by inserting a rotary power brush (attached to a
long, flexible cable) through the vent openings. As the brush
spins and agitates the inside of the duct, the stirred-up dirt
and debris is sucked out of the ventilation system and into the
power vacuum collector.
The power vacuum collector and hand vacuums are all fitted with
high efficiency, surgery room standard HEPA air filters, so no
dust, fibers, or germs are released into the living spaces.
After all the ducts and the air-handling unit have been
brush-vacuum cleaned, everything is reassembled, vent grilles
are replaced, and the system is tested for proper function.
All surfaces in the home are well protected with drop cloths and
plastic sheeting, and special care is taken to leave the home in
the same condition as found before starting the job.
Vent grilles are carefully removed and reinstalled during
the cleaning process, but in instances where the grilles and
screws had been painted over, the customer may need/want to do
some minor paint touch-up afterwards.
We do not, as a rule, sanitize air-handling systems.
However we can, upon request, perform this procedure when necessary; e.g.,
if there are visible signs or other evidence of microbial
contamination in the system, or if mold remediation has been
performed at the residence.
Outdoor condensing units are also cleaned. The area below the
fan is accessed and thoroughly brush-vacuum cleaned. The
condensing coils are washed down, removing any dirt or debris
clogging airflow. This could result in significant energy cost
savings since less electricity is used in the cooling process
when the condensing unit is clean and airflow unrestricted.
Cost:
Pricing is based on the number of air-handling units and the
number of air vents in the home. For details on
