When it comes to your home’s heating, ventilation, and air conditioning (HVAC), it is important to be as educated as possible on the topic. This will help you when talking to HVAC professionals and will make it easier for you to understand what they are telling you.
This blog post will introduce you to 10 common HVAC terms that everyone should know. But for those who don’t know, let’s start with a quick introduction to an HVAC system.
What is an HVAC System?
An HVAC system is a term used for heating, ventilation, and air conditioning. It is a system that regulates the temperature and airflow in a building or home. HVAC systems can be controlled by a manual thermostat or a programmable thermostat.
How Does an HVAC System Work?
An HVAC system is a complex network of interrelated components that work together to control the temperature, air quality, and humidity of a building.
At its core, an HVAC system consists of a series of ducts attached to air handlers. These metal boxes are mounted on the walls or ceilings of the building and contain blowers, motors, coils, filters, humidifiers, and other mechanical parts.
When the HVAC system is turned on, these components work together to draw fresh air from outside the building and circulate it throughout the rooms. The blowers speed up or slow down based on feedback signals from temperature sensors and thermostats; they also adjust their settings according to information gathered from other sensors regarding changes in pressure or humidity within the ducts.
In this way, an HVAC system can maintain consistent temperatures and air quality conditions no matter what the weather may be like outside. So if you’re looking for comfort and efficiency in your home or office, an HVAC system can help you achieve your goals.
9 HVAC Common Terms You Should Know About
The components of an efficiently working HVAC system are critical to understanding. The list below provides some insight into the function and importance each one plays in your home’s air conditioning or heating needs:
1. Thermostat
A thermostat is a device that helps regulate the temperature in a building. It does this by sensing the ambient air temperature and then sending a signal to the HVAC system to either heat or cool the air accordingly. There are two main types of thermostats: manual and programmable.
Manual thermostats are the type that most people are familiar with. They are simple devices with a dial or buttons that you use to set the desired temperature.
On the other hand, programmable thermostats are more advanced and can be programmed to change the temperature at certain times of the day or night. This can help save energy and money, as you can have your HVAC system turned off when you’re not home or when you’re sleeping.
2. Ducts
Ducts are an essential part of an HVAC system. The tubes carry air from the air handlers to different parts of the building. Ducts can be made from metal, fiberglass, or plastic.
One important thing to note about ducts is that they must be adequately sealed to ensure efficient airflow. Any leaks in the ductwork can cause energy losses and result in an HVAC system that doesn’t work as well as it should.

3. Air Handler
The air handler is a vital component of the HVAC system. It is essentially the “heart” of the system, containing all the mechanical parts necessary for moving air around. These components include blowers, motors, coils, filters, humidifiers, and more.
Air handlers come in various shapes and sizes, depending on your needs. They can be mounted on walls or ceilings and usually contain their built-in thermostat so that you can control the temperature independently from the rest of your HVAC system.
4. Blower
The blower is one of the most important parts of an air handler. It is responsible for speeding up or slowing down air as it passes through the unit. This helps maintain consistent temperatures and airflow throughout your building no matter what time of year it is or what weather conditions are outside.
5. Coil
A coil is a coiled metal tube that is responsible for transferring heat to or from the air, depending on whether the HVAC system is in heating or cooling mode. In heating mode, hot gas passes through the coil and transfers its heat to the surrounding air. In cooling mode, a liquid refrigerant absorbs heat from the surrounding air and releases it as it passes through the coil.
6. Furnace
A furnace is a type of heating system that burns fuel (typically natural gas or oil) to heat air, which is then passed through the HVAC system’s ducts and distributed throughout the building.
7. Heat Pump
A heat pump is a type of HVAC system that can both heat and cool a building by transferring heat from one place to another. It works like a furnace in heating mode by transferring heat from outside air or the ground into the building. Cooling mode transfers heat from inside the building to the outside air or ground.
8. Exhaust Outlets
Exhaust outlets are vents that release excess heat, moisture, and other pollutants from the HVAC system. These include bathroom exhaust fans, kitchen range hoods, and dryer vents. Keeping these vents clear and unblocked is important for proper HVAC operation and air quality.
9. Air Filter
Air filters are an important part of HVAC systems because they help remove pollutants, dust, and other particles from the air before it is distributed throughout the building. These need to be regularly replaced to maintain the efficiency and effectiveness of your HVAC system.
10. Compressor
The compressor is a crucial component of HVAC systems that use refrigerant, as it is responsible for pressurizing and circulating the refrigerant throughout the system. With a properly functioning compressor, an HVAC system using refrigerant will be able to heat or cool the building effectively. It’s important to have regular maintenance done on your HVAC system’s compressor to ensure it is working properly.
Wrapping Up
There you have it – a quick introduction to some common HVAC terms. Of course, many more terms and components make up HVAC systems, but understanding these basics can help significantly in discussing HVAC maintenance and operation with professionals or making informed decisions about your HVAC system.
