The Most Important HVAC Components
Having an HVAC system in your home will be very important if you want to ensure comfort of your family throughout the year. But having the HVAC system is not enough. You will also need to make sure that it is in proper working condition all the time if you want it to serve you best. It is therefore very important for you to learn basic facts about the essential components of this system and know the roles they play in maintaining comfortable temperatures in your home.
One of the most important components of the HVAC system is the thermostat. It is the most visible part of this system that is usually set on a prominent and easily accessible wall. You can either program it in advance or set it manually to maintain desired temperatures in your home. In the event that the temperatures in your home become too cold, the thermostat will trigger the heat exchanger to start circulating warm air as needed so as to prevent you from freezing. If the temperatures are too hot, the thermostat will trigger the evaporator coil condensing unit to start circulating cooled air in your home.
The furnace is another very important component of the HVAC system. It is quite large, and as a result it requires substantial space. The based places that you can put it in your home include the attic, your finished basement, the cellar, or a special closet that is specifically designed for it. It is responsible for heating the air that is distributed to various rooms via the HVAC system. The heating process is accomplished using a heat pump, electric resistance, combustion or solar energy.
Another important component of the HVAC system is the heat exchanger. It is usually located inside the housing unit of the furnace. It switches on when the furnace is activated by the thermostat so as to produce warmer temperatures when it is too cold. It does this by pulling in cool air, heating it and then circulating it via ducts as well as out through the vents. The opposite role is played by another important component known as the evaporator coil. It works similarly to an automobile radiator and is responsible for producing cool air.
The condensing unit is also a very important component of the HVAC system. It is usually connected to the evaporator coil and is installed on the outside of the home. After the heat exchanger has cooled the refrigerant to a liquid, this unit pumps the liquid to the evaporator coil so that it can be evaporated into a gas again.
The ductwork is another very important unit of the HVAC system. It simply refers to a system of ducts that transport the air that is either warmed or cooled by the system to different areas or rooms in your home. They are very easy to install since they are made of lightweight aluminum. You can however come across others that are manufactured from steel, polyurethane, flexible plastic, fabric or fiberglass.
