As we move towards a more energy-efficient future, HVAC systems have become an essential component in our homes and workplaces. They help us maintain a comfortable and safe indoor environment, especially in harsh weather conditions. However, traditional HVAC systems have limitations, one of which is, they lack the capacity to regulate temperatures in different rooms, ensuring optimal comfort and improving indoor air quality for every occupant.

Zone control systems offer a range of benefits that traditional HVAC systems cannot match, and one of the most significant benefits is the improvement of indoor air quality. Poston Brothers explain how you can improve indoor air quality and energy efficiency with a zoned system installed in your home.


Zone control systems allow you to control the temperature of each room in your house or building independently. This means that you can adjust the temperature in each zone according to individual preferences. For instance, if you have a guest room that is rarely occupied, you can program the zone’s thermostat to run at a lower temperature, saving energy and, in turn, money. In contrast, rooms that are frequently used, such as common areas, can be set to the desired temperature for maximum comfort.

This individual temperature control helps to reduce energy consumption, which in turn reduces your carbon footprint while saving you money on energy bills.


There are two ways you can add a zoned system to your home. The easiest and most effective way is with ductless mini-splits. Ductless mini-splits are air handlers that are installed in each room, or multiple rooms to create a zone. Each one has its own temperature controls for individualized comfort. Since ductless mini-splits are not connected to ductwork, a place where many contaminants and allergens hide, installing these systems in your home will greatly improve indoor air quality. Ductless mini-splits require an outdoor compressor which can be a heat pump so that they can provide both heating and cooling functions to your space.

The other way to create a zoned system in your home is with dampers. Dampers are installed in your air ducts and will open and close to control how much air is added to a zone. If you have empty bedrooms upstairs, it’s easy to close the dampers and save energy by not allowing conditioned air to enter empty rooms without putting additional strain on your heating and cooling systems. Dampers can also be controlled by individual thermostats.


The benefit of a zone control system goes beyond just controlling the temperature. With the system’s ability to regulate air distribution, it helps significantly with ventilation and improving indoor air quality. The technology allows for air control in each zone, so you can determine airflow levels, reducing dust and other air pollution that may be present in your home or workplace. This is especially beneficial for people with allergies or respiratory issues, who are often sensitive to dust and other particulate matter in the air.

By reducing indoor air pollution, the system helps maintain healthy indoor air quality. In traditional HVAC systems, air circulation occurs throughout the entire building, which can result in the transportation of potentially hazardous materials from one area to another. With zone control systems, you can control the flow of air to specific zones, preventing pollutants from traveling to other parts of the building. This works toward improving indoor air quality alongside an air purifier or air cleaner and promotes a clean and healthy living or working environment.

Another essential aspect of zoning is its ability to offer better humidity control. It is no secret that damp environments can attract a range of harmful substances, including mold and fungi that can irritate respiratory systems. However, with zone control technology, you can control the air conditioning levels accurately in different zones. As a result, this enables you to better manage humidity levels, reducing the risk of moisture buildup that can damage your property or cause health problems. Dehumidifiers and humidifiers are other great tools to help you balance indoor moisture for a more comfortable living area.


Zone control systems offer numerous benefits to homeowners and business owners as they manage temperature levels, air quality, and humidity. The systems are suitable for buildings of all sizes and come with an array of customizable features. Not only do they provide better health and comfort by improving indoor air quality, but they also cut back the cost of utilities by saving energy.
