Almost every home has a heating and air system. They are also called heating, ventilation, and air conditioning systems. What is an HVAC system and how does it benefit your home? Here is a simple introduction to HVAC systems and their purpose.
The main job of an HVAC system is to move warm air. When you turn up the temperature it moves hot air into your house or apartment. If you want to cool down your home the system moves the hot air outside.
Some parts including the air conditioner, heat pump, and furnace work to capture or create hot air. The air is then moved into or outside of your home with the help of blowers and ductwork throughout the house or apartment.
The furnace must have a fuel source to create heat. The most common ways to power a furnace are with electricity or with a fuel like gas, propane, or oil. You can also use a heat pump, which absorbs outdoor heat and transfers it to the inside of your house.
Cooling systems use refrigerant to absorb heat from each room.
These are just a few facts about HVAC systems. For more information, see the linked video.
