Common Air Conditioning Parts & Terms

If you are frequently surrounded by friends working in the air conditioning industry or planning to buy your first AC unit, you could benefit from knowing some of its common parts and terminology. These terms are second nature to the pros, but to any regular person, they are a whole new language.  

To help you out, we will define some of the most common terms you will come across in your conversations about air conditioning units. Here are some basic details that will get you started. 

What Does HVAC Stand For?

HVAC is the most common abbreviation you will hear and see in conversations surrounding air conditioning topics. It stands for heating, ventilation, and air conditioning. Sometimes, you will also see R attached to this abbreviation, which stands for refrigeration. 

An HVAC system can alternate between producing hot or cold temperatures within the home. It comprises six main components: thermostat, heat exchanger, evaporator coil, condenser coil, combustion chamber, and blower motor. 

What Is An Evaporator?

The evaporator is an essential part of your indoor air conditioning unit. It is responsible for removing hot temperatures from the air inside your home. It uses a liquid substance called the refrigerant fluid to achieve this process. If your AC goes out, one of the first things an AC repair technician will check is the evaporator and the levels of the refrigerant fluid.  

The lack of cool air inside the home is one of the first signs that your AC needs to be repaired. But do you have any other signs? Click here to learn more. 

What Is UVA, UVB, and UVC?

UV stands for ultraviolet light. The third letters are either A, B, or C, indicating the ultraviolet light type. UVA and UVB are harmful forms of ultraviolet rays that cause sunburns and even skin conditions such as cancer. In contrast, UVC is a favorable form of ultraviolet rays that help fight off sickness. Air conditioners often come with filters that block UVA and UVB and are best when they contain UVC. Click here to learn more about these filters and why UVC filters are suitable for you. 

What Are Air Filters?

Speaking of air filters, what are they? Air filters are an essential component of the HVAC system because they help separate dust and debris from the air that circulates through the vents. They help maintain a positive quality of air inside the home. They need to be periodically cleaned or replaced to continue their work. Most AC repair service companies recommend changing the air filters every two months. 

What Is A Condenser?

The condenser is a fancy term for the outdoor AC unit. Whether you are heating or cooling your home, it releases hot or cold air outdoors. Condensers are relatively large in size. They must be installed on level ground and in an area free of debris. These factors make a huge difference in the function of your heating and air conditioning unit. 

What Are Air Ducts?

Air ducts are large tubes that travel throughout the home. They connect the heating and air conditioning system to air vents placed inside every room. Unlike a ductless mini split, a central air conditioner relies on air ducts to maintain consistent temperatures throughout the house. Sometimes air ducts need to be inspected by an air conditioning service technician for clogs. If a duct is clogged, it will prevent the air from flowing through the vents.
