What are the Sizes of Air Conditioners?

Unless you use the right air conditioner sizes, the unit will not be able to satisfy your requirements. There are many dimensions available. The Frigidaire FRA052XT7 measures 13.2 x 16 x 12 inches. Other units have dimensions of 14 x 16 x 13, 14 x 15 x 12 and 17 x 16 x 10 inches.

How These Units Work

There are many air conditioning systems. The amount of cooling they provide varies. But the same principles are used in most models.
These appliances function just like a kitchen refrigerator. Basically, the only difference is it doesn’t come in a box.

Many people believe that these appliances bring cold air into a specific area. But that is not how it works. What the appliance does is remove heat from the room. When the heat is gone from the area, it starts to feel cool.


No matter what the air conditioner sizes are, they always make use of evaporation. A useful analogy is an alcohol swab. When pressed against your skin, you feel cool. The alcohol does not reduce your body temperature. When alcohol turns into gas, it pulls heat away. The same principle applies to air conditioning units.


The refrigerant is a chemical found in these cooling units. It can change form from gas to liquid quickly. The refrigerant type most commonly used is Freon. Other kinds are also available. The chemical is set in the system during assembly. Some lubricating oil is applied on the compressor. This is an integral part of the cooling process.


The major parts are the thermostat, compressor, the expansion valve and the condenser. There are also motor fans that enable the conditioned air to flow. Different methods are used for dispatching the heat.

One of the most common is the use of metal fins. The biggest component of the device is usually the compressor. This is necessary because it must handle immense amounts of pressure. These various components interact to remove the hot air and cool the place.

Tips for Buyers

A lot of research is required. What is its capacity? A small unit can handle rooms up to 150 sq ft. If you have a bigger room, you will need a more powerful device. Assess your needs first.

The air conditioner sizes do not necessarily reflect its capacity to cool a room. It will depend on how the appliance is installed and if it is used according to the specifications.
