Upon arriving at your home
the technician will ensure that the HVAC system is turned off prior to the
cleaning.
- The
procedure starts by connecting an 8” vacuum line into the supply section of
the duct work near the furnace, using access panels.
Unlike some competitors SADC does not
charge extra for making access panels.
- The
system is then sealed using magnetic strips covering all supply and return
grills, allowing for concentrated suction.
- Once the
truck mounted vacuum is turned on the system is then put under a negative
pressure and the cleaning process begins.
- High
pressured air (250psi) is forced through each individual supply vent.
- This
process is continued until all supply vents are adequately cleaned. The
vacuum is then switched to the return section of duct work and the procedure
repeated with all return vents.
-
Following the air washing of all supply and return vents, the technician
continues the cleaning in the basement where special tools are inserted into
the duct system through a series of 1” holes. These tools agitate the dust
and direct it towards the vacuum and out of the home.
- Both the
air conditioning coil and furnace are cleaned to finalize the cleaning
procedure.
- All
access panels and 1” holes are sealed air tight and the system is turned
back on to its original settings.
