HVAC Basics for Beginners

Your heating, ventilation, and air conditioning, commonly referred to as the HVAC system, is an integral part of keeping your house at a comfortable temperature. However, many different parts make up this system, and you may be confused by all of it. Fortunately, we're here to help! Here are some basics that everyone that has an HVAC system needs to know.

Furnace And Heat Exchanger

This component can usually be found in the basement. It basically warms the air in your house. Some people refer to it as a boiler, but it is an entirely different appliance. The heat exchanger is found inside the furnace, and it adds heat to the air that comes into the combustion chamber.

Evaporator Coil

This component is found inside of the furnace as well. Refrigerant runs through it and absorbs heat. This allows cold air to blow through your home's air ducts.

Condensing Unit

This component has a similar job to that of an evaporator coil. However, the condensing unit is located outside in your HVAC unit. It does cool air, but it gives off heat as well.


The thermostat is the component of your HVAC system that you've seen the most. It's located on a wall in your home, and you use it to adjust your home's temperature. Many individuals opt for a programmable thermostat so that their home temperature can automatically be adjusted depending on the time of day it is. Many thermostats do have batteries that will need to be changed at some point.

Ductwork And Vents

Air moves through your home via the ductwork and is located in the attic or basement. It allows cold or hot air to be distributed into each of the rooms and out of the vents. You will find vents located on the floor or ceiling in various rooms of your home. When your HVAC unit is running, you will notice that hot or cold air comes out of them, depending on the thermostat temperature.

Air Filter

You may have heard that you need to replace the air filter for your HVAC system monthly but aren't sure where it's located. You can usually find this filter in the return air duct. It will collect dust and debris from the air it's come in contact with.
