Clean
dust off of your indoor coil. With a vacuum cleaner
and soft-brush attachment, you can remove any dust from the top and underside of
the coil. Make sure you only do this when the coil is dry. If you can't get the
coil clean this way, call your dealer for service.
Keep your outdoor condensing unit free of debris. If you keep grass
clippings, leaves, shrubbery and debris away from your outdoor unit, it should
only require minimal care to operate properly. Check the base pan (under the
unit) occasionally and remove debris, to help the unit drain correctly.
If the oudoor becomes dirty,
use a brush or a vacuum cleaner with a soft brush attachment to clean the
surface. To clean dirt that is deep in the coil,
contact your AC dealer.
Take special care of outdoor condensing units in ocean environments. If
your unit is located near a sea coast, you can help preserve its optimal
condition with a little extra care. Ocean mist and sea breezes carry salt,
which
is corrosive to most metals. (Ask your installing contractor about the
appropriate interval in your area.)
Make sure your outdoor unit stays in a level position. If the support
for your split-system outdoor unit shifts or settles and the unit is no longer
level, re-level it promptly to make sure moisture drains properly out of the
unit. If you notice that water or ice collects beneath the unit, arrange for it
to be drained away from the equipment.
Inspect your furnace's combustion area and vent system before each heating
season. If you find dirt, soot or rust, your system may not operate properly
or at its peak efficiency. Call your servicing dealer and do not operate your
furnace until it is professionally inspected and/or repaired.
Have oil-fired boilers inspected annually. Call your servicing dealer
before each heating season to replace your oil filter cartridge and conduct a
thorough inspection of the unit's operation.
