How Does an Air Conditioner Work?When the heat of summer is bearing down on you, few things receive as much appreciation as your home’s air conditioner. Between the cold nights of winter and the dead heat of summer we have a few months of glorious mild temperatures before we need to switch on the air conditioner for relief. Everyone knows what an air conditioner does, but very few know how it actually works to create comfortable, cool air.

Having basic knowledge of how an air conditioner works is useful if you’re facing any problems to know why it happened. Likely you won’t be able to fix it by yourself, but at the very least you’ll have an understanding as to why it might be broken. Our experts at Point Bay have provided some of the basics about an AC unit below, so let’s dive right in:


The Simple Relief of Refrigerant

Basically a liquid called refrigerant, also known as coolant, moves through the air conditioning system collecting heat energy inside the house and leaving it outside of the house. During this transition the refrigerant changes from a liquid to a gas and then back to a liquid over and over again in quick succession.


The system pumps the refrigerant through the air conditioning unit and through an evaporator coil where it changes from liquid to gas. The evaporator coil is a copper coil that resides inside a home’s gas furnace. The refrigerant gas then absorbs heat and moisture from the air inside the house, resulting in cooler, drier air left behind. Next, the furnace fan, or blower, simply circulates the cooler air throughout the home via the duct system.


In order to continue the process, the refrigerant must now be removed from the furnace and converted back into a liquid. The refrigerant gas is sent outside to the compressor in the home’s external air conditioning unit. The compressor places pressure on the gas, turning it back into a liquid, and as it passes through the condenser coil the refrigerant liquid releases the heat energy into the air outside the house. This is done with the assistance of an exhaust fan.


An Important Luxury

If your home is already fitted with an air conditioning system you know how nice of a relief it is when you inside from the blazing New Jersey summer heat. It’s also important to remember that an air conditioner not only cools the air in your home, but also removes moisture, which also aids in the healthiness of the air and overall environment.


To ensure the efficiency and effectiveness of an air conditioning system it’s essential to properly maintain and service its various components through regular tune-ups. A professional and experienced heating and cooling company like Point Bay Energy can easily maintain and schedule annual appointments to keep your system running its best.
