Air Conditioning Systems Filled with refrigerant, these coils draw heat from the air, cooling it. Next, the air moves into the air handler, where a blower sends it into the ducts. As the cool air moves through the ducts, any noxious gasses produced during the process are expelled through the flue.

When it comes to HVAC, as in heating and cooling systems specifically, the ventilation is made up of your air handler, ducts, return vents, and blower assembly. These systems work in tandem to provide “mechanical ventilation”, aiming to reduce humidity levels and normalize temperatures throughout the home.

The HVAC systems are an integral setup of three processes - heat addition, heat extraction, and conditioning. Certainly, HVAC systems are installed almost everywhere including homes, industrial locations, food processing stations, organic warehouses, marine systems, and so on.
