How Does an Air Conditioner Work?

The first air conditioner of modern technology was first introduced in 1902 of a man known as William Carrier. In the past an air conditioner was utilized to reduce humidity. While the function is different, the mechanics remain the same. If you’re curious about how an air conditioner functions and how it works, we’ll explain everything below.

AC Basics

Carrier’s initial AC system utilized steam coils and a fan. Steam coils filled with water, and the fan circulated air over these coils. As the air moved through the cold coils the humidity from outside would condense on the coils and create pleasant, slightly cool air.

While the devices appear incredibly different, the functions are basically identical. Consider an air conditioner like the refrigerator. Instead the stainless steel cabinet walls of your home are what keep cool air inside.

Each central air conditioner includes six main components. Although it requires more than these crucial components to function at its top level it is impossible for any HVAC system to perform its task without these parts.


The thermostat acts as the remote control for the HVAC system in general. It won’t begin cooling until the thermostat instructs it to.


An evaporator is an array of metal coils that make use of refrigerant in order to extract moisture and heat from the air.


A fan is a device that circulates air around the evaporator before dispersing the treated air throughout your home.

Condenser Condenser

This is a different set of coils, but this one releases heat to the air outside of your house.


Refrigerants draw heat from air. The compressor moves refrigerant inside the indoor evaporator coils as well as condenser outside.


A fan that is in the outdoor condenser serves two functions. It draws warm outdoor air into the unit and treats it. Then it releases the heat into the air outside.

The Skyrun air conditioner is split into two components. One in the house and another outside. Both of these components depend on refrigerant for keeping your house cool.

One thing we often hear is the fact that the central air unit recycles air. When you switch off your heating system, and turn it on at AC mode, the initial thing it does is bring air from your home and into the HVAC system.

It is drawn into the vent by a vent, and is then sent to the furnace. Then it is blown over the coil that is used to evaporate. The Evaporator coil converts liquid refrigerant into gas. The refrigerant gas draws moisture and heat from the warm air that passes through it.

After that, cool air is then pumped into your home. The refrigerant is then an extremely hot vapor is sent outside to the condenser. The refrigerant moves between the condenser and the furnace via the compressor.

The hot vapor, which is brimming with the humidity and heat of the air you have treated, flows from the condenser to the evaporator; the condenser, it’s exposed to the outside air.

Once the refrigerant has converted to liquid, it’s now cool and is ready to go through the process. The process continues until your house is at the appropriate temperature by your thermostat.

Types of Air Conditioners

In terms of cooling options the majority of homeowners have several options that they can pick from. We’re not trying to determine which one is the best depending on your personal situation. Below are the 4 most popular kinds of ACs.

Central Air Conditioning

This is the most popular kind of cooling system that we can see across Southern California. It is composed of two units and utilizes the same process as we mentioned in the previous paragraph. It is the most efficient system to cool a complete home. There is the option of setting up a zone in your home and then switching to heat as the seasons change.

Mini-Split System Mini

Split which is also known as a “ductless” system is found in older houses or smaller ones hotels, apartments, or even hotels. It works the same like central AC, but does not depend on ductwork to distribute air. The evaporator coil can be found in one unit inside your home.

Window Units 

Window units are air conditioners with small size that are placed on windowsill. They typically serve to cool a small room or studio. They aren’t recommended for larger areas.

Portable Air Conditioners

A portable air conditioner functions similarly like a traditional window air conditioner in that it is able to be transported from room to room. The units that are standalone are typically with wheels and can be moved around a tiny space.
