Whether you’ve always had central air, or you’ve recently moved into a home which has it, or maybe you’re just starting to contemplate installing a central air unit, you still may not fully understand the central A/C system and how it works. Most people associate air conditioning with cold, when in fact, the science behind making your home cooler actually deals with the transfer of heat. Making your home cooler is actually more about removing existing heat than increasing cool air. Once that heat is removed, the remaining cold air cools your home. Let’s take a look at the major components in order to better understand this system.

Your central air conditioning system is comprised of two key components – the indoor unit and the outdoor unit. They work in tandem to keep your home comfortable year-round…

Indoor Unit

The indoor unit is typically located in a basement or closet, and is usually near where your furnace filter is located. This unit consists of a coil box that contains an evaporator. The evaporator allows for the refrigerant – a cooling fluid inside the coil piping sometimes known by a brand name such as Freon™ – to evaporate and absorb heat. Once the heat is absorbed from inside your home, it leaves nothing but cool air to be sent back into your home.

Outdoor Unit

The outdoor unit is usually located in the rear or side of your home, and it is where the heat from inside your home is dispersed. It contains the compressor, condenser coil and a fan. The heat absorbed from your home’s air is transferred to the refrigerant and then pumped to the outdoor unit. As this heat is absorbed and moved by the refrigerant to the outdoor coil, it passes through the compressor.

The compressor has the primary job of moving the refrigerant throughout the system. This is important as the refrigerant is used over and over again to cool the house. The refrigerant is compressed to a higher pressure, and moved through the outdoor coil known as the condenser. As the refrigerant passes through the condenser, a fan delivers ambient air across the condenser coil causing it to cool. As the process completes, the heat from inside your house is dispersed to the air outside your house. The refrigerant is then pumped back indoors and the entire process repeats. Oh, the beauty of science.

A high-quality, efficient central air conditioning system that is properly installed can provide years of comfort for your home, while keeping your utility bills in check.
