What a Multi-Zone HVAC System Does

HVAC zoning saves money, prevents energy waste, and makes homes more comfortable overall. If you’re looking for a worthwhile improvement for your Burbank home, having your HVAC system zoned is an excellent choice. With zoned heating and cooling, you can lower your carbon footprint and maintain everyone’s ideal indoor temperature.

What Is a Multi-Zone System?

A central HVAC system has a single thermostat and a single system of air ducts that uniformly distributes heated and cooled air throughout the entire building. When you set your preferred temperature at the thermostat, your air conditioner or heater will run until every room reaches or nears this setting. Although central HVAC is effective for keeping homes both comfortable and safe, it’s often responsible for higher than necessary energy bills. After all, when homes are uniformly heated and cooled, homeowners are spending money to regulate temperatures in areas that aren’t being used.

Multi-zone systems make it possible to alter the temperature in one area of the home independent of all others. When zoning central HVAC systems, HVAC companies install dampers in the existing ductwork. Dampers open to permit airflow when heated or cooled air is needed in a specific zone, and they close to block the flow of air after the ideal temperature has already been reached.

How It All Works

Dampers section a home’s existing ductwork off to create individual service areas. Every service area or zone has its own thermostat, and every thermostat guides the opening and closing of nearby dampers. Individual thermostats transmit “satisfied” and “calling” signals to the main control box. This box uses sensors to pick up and respond to the signals that are sent from thermostats. When “satisfied” signals are received, the control box triggers dampers in the respective service area to close. When “calling” signals are sent, dampers reopen.

The Benefits of Having a Multi-Zone HVAC System

Zoning increases the efficiency of existing central HVAC equipment without compromising resident comfort. When homes are zoned, there is no need to heat or cool spaces that no one is currently using. These systems also add value and appeal to residential properties by modernizing one of their most important features.
