Learning about the various parts of the HVAC system and how they all work together can help you stay on top of many maintenance concerns before they require costly repairs.
Overview of the Parts of the HVAC System
HVAC stands for heating, ventilation and air conditioning. While every system is different, the parts of the HVAC system are all the same.
- Furnace – The furnace is the heart of your HVAC system. It’s usually large and requires its own area in your home. Most furnaces are found in a closet or in the attic.
- Evaporator coil – When activated, an evaporator coil provides the home with cool air. These are found inside a metal enclosure that’s attached to the top or the side of the furnace.
- Heat exchanger – This device serves the opposite function of the evaporator coil, working to keep your home warm. Cool air is brought through the heat exchanger and warmed up before being blown out through the ducts.
- Thermostat- The thermostat is what controls the furnace, using a combination of technology and user controls to determine the proper temperature of your home.
- Refrigerant lines – These metal tubes carry the liquid to the evaporator coil and deliver gas to the condensing unit. These lines are very durable and are designed to withstand great temperatures.
- Condensing unit – This item is located away from the furnace, typically outside of the dwelling. Refrigerant gas is cooled inside of the unit and then sent inside to the blowers.
- Ducts – Usually found in the ceiling of a house, ductwork and vents work together to distribute warm or cool air throughout a building. Ducts can generally be found in every room.
- Vents – Typically in the shape of a rectangle, vents allow air to enter the room.
