in the same direction as the arrows. This allows the filter to work appropriately,
as the air exits the filter in the most reinforced part of the filter. The air condi-
tioning filter should fit tightly. A perfect seal is necessary to prevent unfiltered
air from entering and damaging your air conditioning system. Without a perfect
seal and appropriate sizing, the filter is useless. Additionally, the non-
conventional filters may have a higher efficiency and may not fit your system.
This should be checked with an air conditioning company, contractor, or air
conditioning supply company.
Air handler
The outdoor unit, or condensing unit, is part of the air conditioning sys-
tem and is there to provide your home with central air conditioning year-round.
But the outdoor unit also has an indoor unit, called the air handler. It is usually
used in place of a gas furnace and is just as cost efficient. The air handler is the
unit that circulates all of that lovely air we crave in the summer and the heat
that's essential for those living in colder environments and it does so evenly
throughout the home. One unit cannot work without the other, they work to-
gether to provide central air conditioning.
Air handlers operate in conjunction with an air conditioning or heat
pump system, are simple to the naked eye and are generally used instead of a
furnace. An air handler is a box made of sheet metal
, with holes on each side
and a fan that circulates the air. It also houses essential air conditioning parts,
such as an evaporator coil
and an air conditioning filter.
There are various sizes and efficiency ratings of air handlers, mainly due
to the different air conditioning systems. Both are matched together to provide
the very best central air conditioning for the size of the home or office building.
Basically, it's the part of the air conditioning system that solely focuses on the
cooling of the house, while the condensing unit, or "outdoor unit," focuses on
the heating. Both have the same parts yet concentrate on different functions to
provide both heating and air conditioning.
The air handler can also be referred to as an "indoor unit." Whenever you
have to replace the outdoor air conditioning unit, you also have to do the same
with the air handler because both are designed to provide the very best air con-
ditioning system. Not matching these two air condition parts can result in insuf-
