Yes, HVAC includes air conditioning (AC). HVAC systems are designed to provide heating, ventilation, and cooling services to a building or space. The air conditioning component of an HVAC system is responsible for cooling the air in the space, as well as removing humidity and other airborne particles. HVAC systems are typically composed of a furnace, air handler, evaporator coil, condenser coil, and thermostat. All of these components work together to provide a comfortable environment for occupants.
