Is HVAC a boiler?

No, HVAC is not a boiler. HVAC stands for Heating, Ventilation, and Air Conditioning, and is a system that is used to regulate the temperature, humidity, and air quality of a space. It typically consists of a furnace, air conditioner, and other components such as air filters, humidifiers, and thermostats. A boiler, on the other hand, is a device that is used to heat water or generate steam for heating, hot water, and other uses.
