How Your Air Conditioning System Works

How Your Air Conditioning System Works

Your air conditioning system is comprised of many sections that all play their part in cooling your dwelling. Learn how your air conditioning works:

  • Outside Condenser Coil or Heat Pump- A compressor inside the unit provides compression for the system. This compression causes the cooling vapor to heat up. The compressed vapor is then cooled by heat exchange with the outside air, so that the vapor condenses to a fluid, in the condenser. The fluid is then pumped to the inside of the building, where it enters the evaporator coil. The fan mounted on the top of the unit forces the warm air created by the compressor out of the unit, keeping the compressor from overheating. All new condensers must have at least a 14 SEER Efficiency Rating. (A on diagram)
  • Air Handler- The blower motor in this unit is used in the air conditioning process to blow or draw warm air over the evaporator coil. This cools the air, and then blows the cool air into the existing ductwork. All new air handlers must have at least a 14 SEER Efficiency Rating. (B on diagram)
  • Electronic Air Cleaner- An electrically-charged filter installed between the existing ductwork and the furnace or air handler. This places an electric charge on airborne particles from the home then collects the particles on the built-in filters like a magnet. Usually these are more energy efficient than HEPA Air Cleaners, and there is no need to replace filters. Certain brands can eliminate up to 99.98% of airborne particles and allergens. (C on diagram)
  • HEPA Air Cleaner- Has some of the same benefits that an electronic air cleaner, highly effective at removing airborne particles. Filter replacement is necessary periodically. (C on diagram)
  • Ultra-Violet Air Purifier- Usually used in conjunction with an electronic air cleaner or HEPA air cleaner, these purifiers are excellent at eliminating airborne bacteria and viruses. (E on diagram)
  • Humidifier- Used to maintain proper moisture levels in the home. (D on diagram)
  • Evaporator Coil- Inside the evaporator coil, small spray nozzles inject coolant into a chamber, where the pressure drops and the fluid evaporates. Since the evaporation absorbs heat from them, the surroundings cool off. Then the evaporator coil absorbs or adds heat to the system. The vapor is then returned to the compressor. A metering device acts as a restriction in the system to ensure that the heat being absorbed by the system is absorbed at the proper rate (G on diagram)
  • Energy/Heat Recovery Ventilator (ERV/HRV)- HRVs and ERVs recover heat energy in exhaust air, then transfer it to fresh air as it enters the home. They ultimately provide fresh air and improved climate control, while also saving energy by reducing the heating and cooling requirements. ERVs, unlike HRVs, also transfer the humidity of the exhaust air to the intake air. (F & H on diagram)
  • Zone Control Panel- This allows your heating and cooling system to be set up in zones, run by multiple programmable thermostats. It also allows homeowners to have certain areas of the home warmer or cooler than other areas. (I on diagram)

Now that you have a good idea of how your air conditioning works, make sure you invest in regular maintenance to keep it running reliably when you need it most!
