Automotive
air conditioning, more commonly referred to as auto AC, is standard
equipment on modern vehicles. And why wouldn’t it? Our climate is
changing in ways beyond our imagination. One moment it’s humid, the next
it’s freezing. Having a way to control the temperature inside our
vehicles is therefore not a luxury; it is a need.
And
because auto AC is an important part of our cars, AC repair should also
be a staple service in our vehicle’s annual check-up. Aside from this,
AC repair should also be given attention as it is one of the auto parts
that can often lead to very high repair bills if left untended.
As
car owners, it will be a lot easier for us to diagnose and do auto AC
repair if we have some basic knowledge of how it works. Auto AC’s are
closed pressurized systems. Each unit consists of five parts namely
compressor, condenser, accumulator or receiver dryer, expansion valve or
orifice tube, and evaporator. These five components work together to
create an output air temperature cold enough to make us feel
comfortable.
Auto
AC’s have two sides: the high side of the system and its low side. The
former refers to the parts that are under high pressure and high
temperature. Its components are identified by smaller diameter tubing
and are very hot to the touch. Meanwhile, the latter refers to low
pressure components. Its components are larger in diameter and are ice
cold to the touch. These two sides, however, are important in that they
are very handy for diagnosis. If we have a high-pressure line that is
warm and then turns cold in line or even a frozen spot, then it
indicates that there is a clog in this component. It signals us to head
to the nearest auto AC repair shop and have our units checked. Other
common auto AC repair problems include corrosion due to moisture as well
as compressor damage due to the accumulation of particles like metal
flakes, sand, or grit.
It
is highly recommended that professional repairmen fix our auto AC's
whenever problems occur. Working on an air-conditioning system entails
us to have the right tools and skills and not all of us have those.
