Is HVAC same as air conditioning?

No, HVAC and air conditioning are not the same. HVAC stands for Heating, Ventilation, and Air Conditioning, and it is a system that provides heating, cooling, and ventilation services. Air conditioning is a subset of HVAC and is used to cool the air in a space. HVAC systems also include components such as air filters, humidifiers, and dehumidifiers, which are not found in air conditioning systems.
