There is no denying the fact that air conditioners are appliances that help us feel comfortable during the hot summer days. Hence, we have an urge to install air conditioners in our home so that we do not have to face the unbearable heat during the summer season. But, it needs to be mentioned here that just installing an air conditioner is not enough, there are certain things we must know about the air conditioner. This is because; unless we have these ideas we will not be able to take good care of the air conditioner.

So, let us have a look at some of the fact about which we need a careful idea.

In the very first place we need to have a clear idea about the way an air conditioner functions. You must know that air conditioner do not pump in cold air into a room, rather it removes the heat from inside the home and transfers that heat to the outside air. It involves a series of process where the refrigerant plays an important role. As the refrigerant changes state from liquid to gas and again back to liquid there is change of temperature in the room and the room becomes cooler.

It is also important to know the important terms that are associated with air conditioners. Some of these terms include:

• SEER: It is the measure of the efficiency of the air conditioner. Thus, higher the SEER rating of a unit more is the efficiency of the air conditioner.

• Charge: This means adding refrigerant to the unit.

• Compressor: It is the pump that moves the refrigerant from the indoor evaporator to the condenser that is situated outside and again the refrigerant is sent back to the evaporator.

• Duct work: It is the pipe or the conduit through which the air is supplied.

• Evaporator Coil: It is a network of tubes that is located inside the house and it is filled with refrigerant. The main job of the evaporator coil is to take heat and moisture from inside the room as the liquid refrigerant evaporates.

When you have an air conditioner at home, it is important that you should have an idea about the common problems that is faced by an air conditioner. Some of the most common problems of air conditioners include:

• Leaking refrigerant
• Reduced airflow in the system
• Too much of heat generated in the indoor air
• An air conditioner that is improperly sized

Along with the common problems that an air conditioner faces it is also necessary that you are aware of the importance of air ducts, air filters in an air conditioner. For instance, filters remove unwanted particles away from the air so that the home can have a clean air. So it is important that air filters of an air conditioning system are kept clean. Similarly, air ducts help in the circulation of the conditioned air throughout the home.

Last but not the least; when you have an air conditioner, you need to know about the importance of regular maintenance of the air conditioner.
