Average Reviews:
(More customer reviews)I purchased this window air conditioner because I wanted a quiet unit for a small bedroom. The keyword is "quiet", and this unit was supposedly one of the most quiet small units available.
The good part. The unit is very quiet on the outside. This is a good unit if you do not wish to disturb your neighbors. It also makes little or no "water splashing" sounds, which is common in window units.
The bad part: It has characteristics that it should not have at this price. First, the thermostat has a loud "click" that is annoying each time it turns the compressor on or off.
Second, the unit has, in my opinion, an engineering flaw. If there is high humidity, water not only drips off the cooling fins (which is normal), but is also drawn into the air stream. The fan blows the air at high speed through a styrofoam air passage and into the room. Water droplets in the airstream hit the styrofoam at high speed, which creates a loud and annoying "pinging" sound. The intensity and pitch of the "pinging" is a function of humidity and blower speed. The pinging noise decreases, and eventually disappears, as the unit reduces the humidity in the room. If the humidity is high and the outside temperature is not too warm (common in Connecticut), the compressor will remain off for a sufficient time for humidity to return into the room. When the compressor cycles on to again cool the room, the pinging will resume until the humidity in the room is again reduced. This causes an annoying noise pattern that I find unacceptable for sleeping. There is no pinging if there is low humidity.
Third, the unit has a loud low frequency harmonic when the compressor first comes on. This sound tends to vanish after the compressor has run for several minutes.
And fourth, the quality control is not what it should be at this price. The centrifugal (squirrel-cage) fan is made of plastic, and half of one of its blades (ribs) was broken and missing.
Lastly, my emails and complaint letter to customer service were ignored.
