2020 Boiler vs. Furnace Guide | Hot Water or Forced Air

As opposed to furnaces and boilers, air conditioners can only cool and dehumidify the air. They use a compressor to draw air into a condenser, which liquefies the air, sending it into a thermal expansion valve that then gets sent into controlled amounts into the evaporator coil, where it's used to cool down air that a fan sends into vents.
