_______________________________________________________
Air conditioner seems to run too much
_______________________________________________________
The current air conditioner replaced an older model.
The use of
more efficient components may cause the air conditioner to run
longer than an older model, but the total energy consumption will be
less. Newer air conditioners do not emit the blast of cold air you may
be accustomed to from older units, but this is not an indication of
lesser cooling capacity or efficiency. Refer to the efficiency rating
(EER) and capacity rating (in BTU/hr.) marked on the air conditioner.
The air conditioner is in a heavily occupied room, or heat-
producing appliances are in use in the room.
Use exhaust vent
fans while cooking or bathing and try not to use heat-producing
appliances during the hottest part of the day. A higher capacity air
conditioner may be required, depending on the size of the room
being cooled.
_______________________________________________________
Air conditioner cycles on and off too much, or does not
cool/heat room in cooling/heating mode
_______________________________________________________
The Mode or Fan control is set to Power Saver (on some
models).
Use power Saver only when you are asleep or away from
home, since the fan does not circulate the room air continuously.
Use Low Cool, High Cool or Turbo Cool, Turbo Heat or Low Heat for
your best comfort.
The air conditioner is not properly sized for your room.
Check the cooling capabilities of your room air conditioner. Room air
conditioners are not designed to cool multiple rooms.
The filter is dirty or obstructed by debris.
Clean the filter.
The inside evaporator and outside condenser coils are dirty or
obstructed by debris.
There is excessive heat or moisture (open container cooking,
showers, etc.) in the room.
Use a fan to exhaust heat or moisture
from the room. Try not to use heat producing appliances during the
hottest part of the day.
The louvers are blocked.
Install the air conditioner in a location
where the louvers are free from curtains, blinds, furniture, etc.
The outside temperature is below 65ºF (18ºC).
Do not try to
operate your air conditioner in the cooling mode when the outside
temperature is below 65ºF (18ºC).
The temperature of the room you are trying to cool is extremely
hot.
Allow extra time for the air conditioner to cool off a very hot
room.
Windows or doors to the outside are open.
Close all windows and
doors.
The temperature set point or Thermostat control is not at a cool
enough setting.
Adjust the temperature set point to a cooler setting
by turning the knob clockwise to a lower number. Turn the Fan
Speed control to Turbo Coo.
