As long as our homes receive proper heating and air conditioning, we are never interested in what actually happens.
There is more behind this phenomenon and knowing a little bit about the parts behind our comfort can give you a basic understanding of how an HVAC system works.
Even though HVAC systems are not the same, most of them have the same parts needed for heating, cooling, and air conditioning. One of the most essential parts of an HVAC system is the furnace, which is basically the heat supplier. The furnace is usually stored in a hidden place such as a closet or basement. It supplies heat to different areas of a home through the ducts. A furnace can use either gas (oil/gas) or electricity as its heat source. Every furnace unit has a heat exchanger, which is responsible for the heating air. Also, it has an air blower for pulling in cold air in the home and then blowing it back into the house. When a furnace unit is switched on, the heating makes the heat exchanger’s outside walls very hot. The air handler then blows air over the extremely hot exterior walls of the heat exchanger. It plays a significant role in making sure the warm air reaches inside your home. Some furnaces can be operated manually by the user, while others have a thermostat that detects whether cold or hot air is needed. A thermostat is better when it comes to saving energy because it turns off the furnace as soon as the temperature reaches the desired level.
