Normal Sounds

Sound of Rushing Air
At the front of the unit,
you may hear the sound
of rushing air being moved
by the fan.
Gurgle/Hiss
"Gurgling or hissing" noise may
be heard due to refrigerant passing
through evaporator during normal
operation.
Then ...
Inside blower continues operating for one minute to use as much cooling that is
available in the evaporator.
Newer, higher efficiency Air Conditioner may run longer to cool the room. Total
energy consumption is less due to higher efficiency.
A higher capacity unit may be required depending on the size of the room being
cooled. (Page 9)
Then ...
Unit should be mounted on a 1/4" downward slope to the outside (1/2 bubble on a
carpenter's level) to provide proper drainage. Reposition or shim cabinet as necessary.
DO NOT drill drain pan.
Then ...
Normal operation during hot and humid days.
Then ...
Verify batteries are installed properly. (Page 5)
The remote may not work properly when used at extreme angles to the front of the unit.
Then ...
Compressor - Normal noise due to modern high efficiency compressors. (Page 11)
Fan/Motor - Normal noise of higher efficiency fans pushing air further into the room.
(Page 11)
Condenser - Normal noise of water hitting the condenser to increase energy efficiency.
(Page 11)
Evaporator - Normal noise of refrigerant passing through evaporation. (Page 11)
Electronic Control - Normal noise when electronic control settings are changed.
Unit Vibration - Due to poor wall or window construction or incorrect installation. (Page 11)
High Pitched Whine
Today's high efficiency
compressors may have a
high pitched whine during
the cooling cycle.
11
Vibration
Unit may vibrate and make
noise because of poor wall
or window construction or
incorrect installation.
Pinging or Swishing
Droplets of water hitting
condenser during normal
operation may cause
"pinging or swishing"
sounds.
