An excellent way to understand your HVAC system better and make good decisions when upgrading or replacing it is by learning the common HVAC terminology. Important HVAC terminology includes:
  • Air conditioner. This is a system or appliance designed to remove heat and humidity from a building or just a room.
  • Heat pump. A unit that can heat or cool indoor spaces in mild climates by moving heat between two reservoirs.
  • Refrigerant. A fluid chemical used in heat pumps and air conditioners to transfer heat out of or into indoor air. It has a very low boiling point, which allows it to absorb and release heat.
  • Evaporator coil. Also known as the indoor coil, this device absorbs heat from the air passing over it. The heat changes the liquid refrigerant flowing through the coil into a vapor to initiate the cooling process.
  • Condenser coil. Also known as the outdoor coil, it is the specific area where the refrigerant is condensed from gas to liquid, releasing the heat carried by the refrigerant from the system.
  • Refrigerant line. A copper tubing that connects the evaporator coil to the condenser coil.
  • Compressor. The part of an HVAC unit that pressurizes the refrigerant to enable it to move through the system.
  • Condenser. The unit containing all the components needed to expel heat from the AC system. It's usually placed outdoors.
  • Ductwork. A network of fiberboard, flexible, or metal material designed to deliver air from your HVAC system to different zones of your home.
  • Air handler. A moving HVAC part inside your house that pushes air through your ductwork. A blower coil or furnace can serve this function.
  • SEER. The Seasonal Energy Efficiency Ratio rates the efficiency of air conditioners.
  • AFUE. The Annual Fuel Utilization Efficiency measures the efficiency of furnaces.
  • Energy Star. The federal Energy Star program gives this designation to heating and cooling systems that perform above the government's minimum efficiency standards.
