The definition of an induction system HVAC is a type of heating and cooling system that uses an air handler to distribute air throughout a building. This system is made up of two main components: an air handler and an induction unit. The air handler is responsible for taking in air from outside and pushing it through the ducts to the various rooms in the building. The induction unit is responsible for taking the air from the air handler and using it to heat or cool the building. The induction unit works by using a fan to draw in the air from outside and then using a heat exchanger to heat or cool the air. This heated or cooled air is then pushed through the ducts to the various rooms in the building. An induction system HVAC is an efficient and cost-effective way to heat and cool a building. It is also relatively easy to install and maintain.
