consumers acknowledge the fact that air conditioning and heating
systems offer indoor comfort by controlling the temperature
and relative humidity inside their homes, but they fail to
recognize another important function of their system; cleaning
replacing the return air filters on a regular basis (usually
monthly), homeowners can help reduce the dust and dirt particles
floating through their homes while also extending the life
of their heating and cooling system. Dirt that flows into
the cooling coil can clog the fins and reduce the efficiency
of the entire system, shortening its life and increasing operating
costs. Dirt encourages mold growth and limits the coil's ability
to remove moisture from the air. In most cases, the coil will
have to be completely removed and cleaned outside the home
in order to remove heavy deposits of dirt and dust. Furthermore,
dirty coils can hide small ruptures in the internal tubes,
masking system leaks and increasing the amount of time needed
to diagnose and repair system problems.
choosing the type of filters to use for your existing system
or to protect your investment in a new system, the efficiency
of the filter must be considered. The "99 cent"
filters (shown left) typically found at the supermarket provide
only marginal levels of filtration. Replacing traditional
filters with pleated filters will increase the level filtration
by providing more surface area.
you have particularly heavy dust and dander problems, especially
in homes with pets, an Amana Air
Bear® filter will provide the highest level
of filtration. Nash Mechanical
recommends installing an Air Bear with every new system. The
is generally placed immediately in front of the system, eliminating
the dust particles that would otherwise enter the system between
the return air grill, where filters are traditionally placed,
and the actual system.
