What is HVAC System Zoning?

HVAC system zoning is becoming a popular choice for homeowners to improve their comfort at home while also lowering their energy bills. If you have ever wanted to know more, read on to find out the details about HVAC system zoning, whether this system is right for you, benefits, and options!

What is HVAC System Zoning?

HVAC system zoning is a way to control temperatures in different areas or zones in your home. It uses dampers to control the airflow through your home’s ductwork and thermostats to control the dampers. This system allows you to keep your entire home at the same temperature or allows you to restrict heating and cooling in areas rarely used. 

Additionally, HVAC system zoning extends the life of your system. If you manually open and close the vents in rooms of your home, you waste time and also drastically reduce the airflow. This practice ultimately damages your HVAC unit.

HVAC system zoning is a professionally installed system including a series of dampers and thermostats. Typically, each thermostat controls an individual zone or room of your home. Our HVAC system zoning professionals design a system to meet your capacity needs and energy goals. We install HVAC system zoning with new heating and air equipment or retrofit to work with existing systems.

How Does HVAC System Zoning Work?

HVAC System zoning has two major components: motorized dampers and thermostats. The dampers are installed in the ducts of your HVAC system, and are controlled by the thermostat. HVAC system zoning includes single or multiple dampers controlled in a single room. We determine the number of dampers by the number of ducts that run to a specific room.

In each zone, there is a dedicated thermostat. All thermostats in a home run to a central control panel that interfaces between the thermostats and the HVAC unit. If an area requires cool air, the thermostat opens the dampers in that zone and sends the signal to the control panel to turn on the air conditioner. 

Once it reaches the desired temperature, the thermostat closes the dampers and signals the control panel to turn off the air conditioner. If another zone requires cool air while the air conditioner is running, the thermostat simply opens the dampers and allows the cool air to flow into that space.

Ductless Mini Split Systems 

Ductless mini split systems are another great way to achieve HVAC system zoning in your home. Ductless mini split systems are independent units installed in each room or zone. They are made of two components: an indoor air handler and outdoor compressor. You may set each air handler to a different temperature.

Ductless mini split systems are great for homes without existing ductwork, or to add heating and cooling where it does not exist (think sun porches, garages or attic spaces). They are also easy to install and have less air loss because there are no ducts for the air to flow through and possibly escape.
