Can I do Myself?
With the proper maintenance and care, your equipment will
operate economically and dependably. There are a few simple,
routine maintenance operations you can do to help ensure the
best performance and comfort from your system.
Before you perform any kind of maintenance, consider these
important safety precautions.
- Disconnect all electrical power to the unit before removing
access panels to perform maintenance. Please note that there
may be more than one power connection switch.
- Although Daikin takes special care to prevent sharp edges
in the construction of our equipment, it's best to be very
careful when you handle parts or reach into units.
Check the air filter in your furnace or fan coil
every 3 to 4 weeks. A dirty filter will cause excessive
strain on your furnace, air conditioner or heat pump. Replace
your filter when necessary, or clean it if you have the reusable
type. (If you have a reusable filter, make sure it's completely
dry before you re-install it.) The prefilter and collection
cells of an electronic air cleaner should be cleaned at least
two or three times per year.
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 us 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 outdoor coil 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 Pro-Air.
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. Although new Carrier units
are made out of galvanized metal and are protected by top-grade
paint, you can add life to your unit by washing all exposed
surfaces and the coil approximately every three months. (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 Pro-Air and do not operate your furnace until
it is professionally inspected and/or repaired.
Have oil-fired boilers inspected annually.
Call Pro-Air before each heating season to replace your oil
filter cartridge and conduct a thorough inspection of the
Clean your humidifier at the beginning of every heating
season. Review your owner's manual for the proper
procedure to clean the external and internal components of
your unit. The evaporator pad should also be replaced before
each heating season. If the water in your area is hard or
has high mineral content, you may need to clean or service
your humidifier more frequently.
Clean the core and air filters on a ventilator at
least every three months. You can vacuum the core
of an energy recovery ventilator as long as it is dry and
the outdoor temperature is between 60 F (16 C) and 75 F (24
C). Heat recovery ventilator cores can be soaked for three
hours in a solution of warm water and mild soap and then rinsed.
Ventilator air filters are washable: just use a vacuum to
remove the heaviest accumulation of dust and then wash them
in lukewarm water. Replace them after they are completely
