How Does a Zoned System Work?

These systems work just like the light switches in your home, so that you don't have to illuminate your entire home when you only need light in a specific place. Zoned HVAC systems work by controlling the flow of air to individual spaces.

They do so by:

  • Using dampers. Dampers inside ductwork open and close based on the area's need for conditioned air. When the damper is closed, it won't allow air to flow into the ducts that serve that specific zone.
  • Using individual thermostats. Each zone has its own thermostat that controls when the area receives heated or cooled air. 

Many homes are suitable candidates for zoning systems, especially those with:

  • Two or more stories.
  • Raised ceilings in a few areas.
  • Unequal placement of windows, especially those with southern or western exposure. 
  • Rooms that are infrequently used. 
  • Family members with different temperature preferences.

What's Involved

Dividing a home into separate zones involves working with your trusted HVAC contractor to determine how many zones you'll need based on your home's thermal characteristics and your usage patterns. The contractor will install the motorized dampers inside the ducts for each zone, along with the individual thermostats each zone requires.

The individual thermostats will be connected to a central panel which tells your HVAC system to turn on and open that zone's damper. If you opt for programmable thermostats for each zone, the installation team will help you program them based on occupancy. 

Direct Benefits of Zoning Systems

  • Lower energy bills. Instead of conditioning your entire home, only the areas that need warmer or cooler air receive it. 
  • Improved comfort. Your home won't have hot or cold spots, since the thermostats maintain your comfort exactly as you want it.
