In order to understand how an HVAC zoning system works, it helps to first look at how a traditional HVAC system functions to then understand how it can be optimized with zoning.
Traditional ducted HVAC systems work by treating the entire space as one zone. For example, if you turn the temperature settings down, then your HVAC system will transport air through your ducts to cool your entire house equally in order to reach your desired temperature.
An HVAC zoning system will divide your home into separate zones, each with its own thermostat that sends messages to the central control panel to either lower or raise the temperature in that space. With this HVAC system, if you turn the AC or heat on in one area of the home, then only that selected zone will receive airflow to reach that chosen temperature.
How does this all work? The components that differentiate these central HVAC systems from zoned HVAC systems are the HVAC zoning dampers. HVAC dampers are large, movable plates or valves that are located in your air duct system. They regulate the airflow and redirect it to the different zones of your home.
A zoned HVAC system is made up of 3 key components:
- Central control panel
- Electronic dampers
The thermostats all connect to the central control panel, which then controls the dampers in your air ducts. Dampers control where the heated or cooled air goes by opening up to allow air to flow into certain areas while blocking off others.
While an HVAC zoning system could be the answer to temperature control problems in many homes, they are not always the best fit. The best way to determine if a zoned HVAC system will fit your household’s needs is to speak to an HVAC professional. You should contact an HVAC technician at Integrity Heat & Air today about the possibility of an HVAC zoning system if your home has the following traits:
- Multilevel (including basement or attic)
- High ceilings
- Large windows
- Rooms or spaces that are not used much
Zoned HVAC systems were created in order to give homeowners more control over their home’s temperature levels and energy usage while saving them money. Let’s take a look at the ways your wallet could benefit.
