What Makes Up a Heating and Air Conditioning System?

Your HVAC system not only keeps your home comfortable, but it also helps keep your indoor air clean. Given its crucial job, it pays to know the basics. This way, you can detect problems faster, letting your technician repair it in record time. Doing so will prevent premature wear and tear and even costly breakdowns later on. Below, we’ll break down each of your HVAC system’s crucial parts so that you better understand how your furnace and air conditioner work.

Key Components of a Heating and Air Conditioning System

Your heating and air conditioning system is composed of several components working together. That’s why when one component goes down, many of the others will often follow suit. Here’s a list of each part and the roles they play:

  • Furnace. The furnace is one of the major components of your HVAC system. Its purpose is to produce heated air, which will be circulated in the entire home. Depending on the model, it may use any of the four different heat sources: combustion, heat pump, electric resistance or solar energy.
  • Heat Exchanger. This component activates when the furnace is turned on by the thermostat to improve heating capabilities during winter. It draws cool air, warms it up and distributes the heated air via your ductwork. You can find this inside your furnace unit’s housing.
  • Evaporator coil. This operates in contrast to the heat exchanger. It cools the air during summer. You can locate this in a metal enclosure on the furnace’s exterior.
  • Thermostat. This is a device that triggers the heat exchanger or evaporator coil-condensing unit to disperse warm or cool air as necessary. You can either program it in advance or adjust it manually to maintain your preferred indoor temperature.
  • Refrigerant lines. These narrow tubes, made from a heat- and cold-resistant metal, bring the refrigerant to the condensing unit in gas form and send it back into the evaporator coil in liquid form.
  • Condensing Unit. Considered the heart of your HVAC system, this sits out on the back or side of your home. It is packed with refrigerant gas and linked to the evaporator coil. When the refrigerant cools into a liquid by heat exchange with the outdoor air, the condenser unit sends it to the evaporator coil to vaporize it into gas again.
  • Vents. Vents are rectangular outlets that deliver the heated or cooled air from the ducts into every room of your home. They are located on or near the ceiling and they direct air downward. They can be manually controlled to control heating or cooling in the room.
  • Ductwork. This comprises a system of ducts that carry treated air from the HVAC system to various areas of your home. Most ducts are made of aluminum, but they can also be constructed from plastic, steel or fiberglass.
