What Is an A/C Unit and How Does It Work?

An air conditioning (A/C) unit is designed to keep the temperature and humidity within a confined space comfortable and consistent. It works by using a refrigerant, typically Freon, to cool the air and a fan to distribute the cooled air throughout the area.

The A/C unit has four main components: the compressor, condenser, evaporator, and expansion valve. The compressor is responsible for pressurizing the refrigerant and converting it from a low-pressure gas to a high-pressure liquid. The condenser then takes the pressurized fluid and cools it to a lower temperature, flipping it back to a low-pressure gas. The evaporator is responsible for absorbing the heat from the air inside the space and transferring it to the refrigerant. The expansion valve releases the now colder refrigerant into the evaporator.

The cycle is repeated continuously until the desired temperature and humidity levels are achieved. The fan inside the A/C unit is responsible for distributing the cooled air throughout the space, creating a comfortable environment.

A/C units are essential for keeping your home or office comfortable during the hot summer. They are also crucial for maintaining good air quality, as they can help filter out dust and other allergens. An A/C unit can provide years of reliable performance with the proper maintenance and care.

Types of Home A/C Units

Air conditioners are essential in hot climates, providing relief from heat and humidity. But with so many different home A/C units on the market, it can take time to decide which is best for your home. To help you make an informed decision, here is a brief overview of the most common home A/C units.

Split System Air Conditioners

Split system air conditioners are the most common home A/C unit and usually consist of two separate units: an indoor unit and an outdoor unit. The indoor unit is typically mounted on the wall or ceiling and circulates the cooled air throughout the home. The outdoor team is responsible for cooling the air before it is sent indoors. Split system air conditioners are typically more energy efficient than other types of air conditioners and can be used to heat the home.

Window Unit Air Conditioners

Window unit air conditioners are one of the most affordable and easy-to-install types of A/C units. As the name implies, they are installed in a window or through a wall. Window units are generally suitable for cooling small spaces, such as bedrooms and living rooms, but could be better for cooling large areas. They are noisier than other air conditioners and can be more prone to leaks than other A/C units.

Ductless Mini-Split Air Conditioners

Ductless mini-split air conditioners are similar to split system air conditioners in that they consist of two separate units. Still, the significant difference is that they do not require ductwork installation. Instead, the indoor unit is mounted directly to the wall or ceiling and is connected to the outdoor unit using a conduit. Ductless mini-split air conditioners are energy efficient and can heat and cool the home. They are also relatively quiet and can be used to control the temperature of individual rooms.

Portable Air Conditioners

Portable air conditioners are an easy-to-install option for cooling small spaces. They are typically mounted on a window, and their exhaust is vented outside. Portable air conditioners are relatively energy efficient and can be moved from room to room, making them an excellent option for renters or those who need temporary cooling solutions.
