So, How DO HVAC Dampers Work, Anyway?

The most helpful start to understanding how HVAC dampers work is first mentioning what they are. Dampers in your HVAC system are the tools that help regulate temperature around the home when using an HVAC zoning system. They are like valves that decide how much heated or cooled air is required to feed into different areas of your ductwork that will then lower or raise the zone’s temperature to its desired number. HVAC dampers work to help give homeowners control over the amount of air that is distributed to the zone in question.

Damper systems are different than simply closing a vent in the floor or on the wall. A closed vent still allows the heated or cooled air to travel the length of the duct, where it then just sits and wastes, going back to room temperature. HVAC dampers work by being situated closer to the mouth of the distribution pipe and will push or hold air from that point as needed. The pressure in the pipe will then redistribute the airflow to whatever zone requires regulating at that time.

How Do HVAC Dampers Operate?

This question may seem like a repeat of the question “how do HVAC dampers work?” but it is slightly different because it covers that actual mechanism of the dampers, and the functions of manual and motorized ones.

HVAC dampers come in two types – manual and motorized. Manual dampers work by the homeowner twisting a screw to regulate the airflow that goes into a certain zone. On the other hand, a motorized damper functions on its own. Motorized dampers are more convenient for homeowners with a programmed HVAC zoning system, as they work in concert with the whole HVAC system and follow the home’s heating and cooling regime set by the owner.
