INTRODUCTION
How and Why
Your room air conditioner provides the following functions to make hot weather living more
comfortable:
1.Cools and circulates the room air.
2.Lowers humidity by removing excess moisture.
3.Filters out summertime dust, dirt, and some airborne impurities.
The air conditioner performs these functions by drawing the room air through a filter which traps
dust and dirt particles. The air then passes over a cooling coil which refrigerates the air and
removes excess moisture. The same air is then returned to the room-cooler, drier, and cleaner.
Moisture removed from the room air is carried to the outside and evaporated.
Your air conditioner is designed to be easy to operate and to provide plenty of cooling power.
Normal Sounds
Aside from the regular fan motor and compressor sounds coming from your air conditioner, you will once
in a while hear a pinging sound. This is the result of moisture inside the room air being thrown against the
running fan. This is normal and should not be caused for concern. Also, do not be alarmed if you hear a
slight hissing or gurgling sound coming from your air conditioner after it is off. These are normal coolant
noises.
Fan
You may hear air
movement from the
fan.
Capacitance and Running Time
Proper unit size is important in deciding the desired comfort for the area you want to cool. The proper
size is determined by the number of square feet in the area to be cooled.
Whenever the heat or humidity load is above normal, the air conditioner must run longer and more often
to keep the desired temperature you have selected. Under heavy heat load conditions, the air conditioner
may need to run constantly to keep the temperature you want.

Compressor
The modern high efficiency compressor
may have a high pitched hum or pulsating
noise that cycles on and off.

Condenser
You may hear droplets of water
hitting the condenser, causing
a pinging or clicking sound.
