More of what Larry
Installation Process is the one major step that makes the system what
it is. We at Andrews Mechanical, Inc believe that the indoor
coil (the ones in the furnace) should be in the factory case with the front
panel conveniently positioned. This will make it easier for the panel to be
removed in order to inspect, service and cleaning of the coils for any periodic
maintenance. Our unique 'Clean-Out Port' System below the coils also makes
this possible along with less expensive to inspect and clean.
The 'Return Boot' (section at the base of the furnace) that collects the air
from the entire home is fitted with our Hollow
Core Vanes that are used to turn or direct the air to more efficiently
move air and lower the energy costs in doing it. It's also quieter inside
We ensure the proper line size from the outdoor unit portion to the indoor
unit of the A/C system. All lines are then purged with dry Nitrogen while
the brazing is taking place to prevent the interior of the pipes from corroding
or soot from forming. By preventing unnecessary contamination we extend the
life of the compressor of the system by making it have less internal wear.
The completed, closed system is then pressure tested (keeps the freon in and
the air out!) to 300 psi! Once this test is complete, the system is
subjected to a deep vacuum test of over 29" of vacuum to ensure
the system does not have residual contamination. Finally, your Air Conditioning
system is charged to factory specifications and put in service.
These steps, while they seem tedious, are the insurance we use to provide
you, our customer, with a long lasting, efficient, trouble free A/C system."
