HVAC

HVAC stands for Heating, Ventilation, and Air Conditioning. It's the broad term for all the equipment that controls the temperature, humidity, and air quality in a building. Traditional HVAC systems use a furnace or air handler connected to a network of ducts. Ductless systems like mini splits are HVAC too — they just skip the ductwork. When someone says "my HVAC is acting up," they mean something in their heating or cooling setup isn't working right. It's a catch-all term. What it actually covers depends on the system.
