The
most
important
thing
you
can
do
to
maintain
unit
efficiency
is
to
clean
the
filters
at
least
every
30
days
(or
sooner
depending
on
application).
Clogged
filters
reduce
cooling,
heating
and
airflow.
Keeping
filters
clean
will:
*
Decrease
cost
of
operation.
*
Save
energy.
«
Prevent
clogged
indoor
coil.
*
Reduce
risk
of
premature
component
failure.
To
Clean
Air
Filters:
*
Vacuum
off
heavy
