COMPLAINT
Unit Does Not Cool/Heat Room Suffi ciently, Or
Cycles On And Off Too Frequently (continued).
Unit Runs Too Much.
CAUSE
The outside temperature is below
60°F (16° C).
The digital control is set to fan
cycling mode.
The air conditioner has insuffi cient
cooling capacity to match the heat
gain of the room.
The air conditioner has insuffi cient
heating capacity to match the heat
loss of the room.
This may be due to an excessive
heat load in the room.
It may also be due to an improperly
sized unit.
This may be normal for higher
effi ciency (EER) air conditioners.
You may notice that the discharge
air temperature of your new air
conditioner may not seem as cold
as you may be accustomed to from
older units. This does not, however,
indicate a reduction in the cooling
capacity of the unit.
SOLUTION
Do not try to operate your air conditioner in the
cooling mode when the outside temperature is
below 60°F (16° C). The unit will not cool properly,
and the unit may be damaged.
Since the fan does not circulate the room air
continuously at this setting, the room air does not
mix as well and hot (or cold) spots may result.
Using the continuous fan setting is recommended
to obtain optimum comfort levels.
Check the cooling capacity of your unit to ensure it
is properly sized for the room in which it is installed.
Room air conditioners are not designed to cool
multiple rooms.
Check the heating capacity of your unit. Air
conditioners are sized to meet the cooling load,
and heater size is then selected to meet the
heating load. In extreme northern climates, room
air conditioners may not be able to be used as a
primary source of heat.
If there are heat producing appliances in use in the
room, or if the room is heavily occupied, the unit will
need to run longer to remove the additional heat.
Be sure to use exhaust vent fans while cooking
or bathing and, if possible, try not to use heat
producing appliances during the hottest part of the
day.
The use of higher effi ciency components in your
new air conditioner may result in the unit running
longer than you feel it should. This may be more
apparent, if it replaced an older, less effi cient,
model. The actual energy usage, however, will be
signifi cantly less when compared to older models.
The energy effi ciency ratio (EER) and cooling
capacity rating (Btu/h) listed on the unit's rating
plate are both agency certifi ed.
