What Are HVAC Zoning Systems?

Some areas in the home sometimes feel colder or hotter than the rest of the home. This can occur due to poor temperature control, poor insulation, lack of window coverings, or excessive sun exposure. An HVAC zoning system helps prevent fluctuations in temperature and keeps the entire home at a consistent temperature.

How a Zoning System Works

A zoning system heats and cools a home by zone. Zones can be made up of specific rooms, areas, or even floors. The dampers serve as the main component of a zoning system and are installed inside the duct, allowing the cooled or heated air to travel to specific zones.

The dampers in each zone are connected to a thermostat that is wired into a centralized control panel. The panel controls the different thermostats and dampers within a zone.

In the past, homes needed separate HVAC systems to control temperature in different parts of the home. Today, one HVAC system can have multiple thermostats controlling temperature in various zones.

Benefits of a Zoning System

Large homes with many rooms and floors will benefit the most from a zoning system. Homes without a zoning system often have high temperatures on the top floor, and low temperatures on the bottom floor, even if the thermostat is set to a certain degree. 

A zoning system offers greater control over indoor temperature and ensures everyone feels comfortable, no matter what part of the home they’re in.

A zoning system also gives homeowners the option of not heating or cooling certain parts of the home that are rarely used or occupied. This can help save energy and lower monthly utility bills, especially during seasons with extreme temperatures.

Because zoning systems rely on smart thermostats, homeowners can expect greater efficiency and ease of use. Smart thermostats can be controlled by smartphone apps even when away from home.

How to Choose an HVAC Zoning System

When considering an HVAC zoning system, homeowners will need to find a compatible zone control panel, install thermostats, know the size of their ducts, purchase dampers, calculate airflow rate, know the material used in their ductwork, install sensors, and purchase a warranty. Getting all of these steps down is key to an efficient HVAC zoning system.
