An HVAC zoning system (also referred to as “zoned HVAC”) is a heating and cooling system that uses dampers in the ductwork to regulate and redirect air to specific areas of the home. This allows for the creation of customized temperature zones throughout the home for increased comfort and efficiency.

What is HVAC Zoning?

 HVAC zoning is the process of separating your heating and cooling system so it delivers different comfort levels to each area of the home. This process allows you to set the conditions independently for each section of your house. You might keep the bedrooms cooler at night while focusing your air conditioning on the kitchen and living room areas during the day. HVAC zoning gives you a higher degree of control and customization over the temperature in your home.

How HVAC Zoning Works

A zoning system for your HVAC system is a way to control the temperature for each area, or “zone” in your home, rather than have to heat or cool the whole house to the same temperature. With a zoning system, you can set temperatures differently for either individual rooms or sections of your home.

Typically, with forced air systems there is only one thermostat to control the heating and cooling for the entire home. Once that thermostat calls for heating or cooling there is virtually no way to control the temperature in each room of the house except by manually closing off the outlets in each room. This manual method is time-consuming and can cause harm to the HVAC unit, as closing off too many outlets can reduce the airflow. This could shorten the life of the furnace, air conditioner or heat pump.

Zoning solves this problem. It also allows you to save energy (and therefore money) by not heating or cooling rooms when they don’t need it. If, for example, you live in a two-story home and don’t use the upstairs very much, you can set the thermostat upstairs so that it doesn’t call for heat or cool air very often.

A zoning system with hvac damper control is a professionally installed control system consisting of a damper and thermostat for each room or zone of the house. This control system is wired into a central control panel that sequences each thermostat’s call with the zone dampers in the ducts and the HVAC system.

How does zoning work?

Zoning is a simple product and concept. Zoning provides the ability to only condition those rooms that need heating or cooling and does not allow conditioned air into those zones not requiring it. Zoning does this through a series of components, the first being motorized dampers that open and close based on the demands of the zone thermostats. These dampers insert into the ducts or can be installed at the air outlet for each room or zone. Multiple dampers can be controlled together for a single zone if multiple ducts serve a single room or zone.

The next key components are the zone thermostats. In existing homes, the existing thermostat can be used as a zone thermostat. As each zone is divided, each zone uses a thermostat to control the heating, cooling and fan operation for its individual zone. The zone thermostats and dampers are wired into a central control panel. The panel then also connects to the thermostat connections on the HVAC Unit. Instead of using one central thermostat, the control panel allows the unit to be controlled by multiple thermostats.

As each thermostat calls for heating or cooling, the panel takes the first call from any zone. If it’s heating, for example, it will keep open the damper to the calling zone, close the dampers to satisfied zones not calling for heating, activate the furnace or heat pump and begin supplying air only to that zone. If during this call other zones call for heating, those zone dampers would open and heated air would be supplied to those zones as well. Once all heating calls are satisfied the panel will shut off the furnace or heat pump.

To understand why zoning makes sense, think of it like having a light switch in every room of the house. You wouldn’t install just one light switch to turn on and off all of the lights in the house, would you? The same is true for heating and cooling. One thermostat turning on the heating or cooling for the entire house, when you only need it in one room or zone, wastes energy.

How Does It Work?

HVAC zone control utilizes a series of dampers that are installed either in the ducts or at the air vents. These dampers can open or close mechanically as needed to deliver airflow to each part of the home. Each zone has its own thermostat so you can adjust the temperature individually for that section of the house. If multiple ducts or air registers serve a particular part of the home, multiple dampers will move at once.

It’s important to have a zoned HVAC system professionally installed. The process of setting up the layout for this installation can be complex. A trained HVAC technician can properly evaluate the layout of your home and help you set up efficient zoning.

What are the Benefits of Zoning?

HVAC zoning offers several benefits for both your home and your wallet. Some of the perks that you’ll enjoy with the best hvac zoning system include:

  1. Better energy efficiency: A zoned system diverts air away from areas that don’t need it so you’re using less energy to keep your home comfortable. Zoning is more efficient than simply closing the air vents in each room because the dampers provide a better seal.
  2. Personalized comfort levels: Do you have thermostat wars in your home? A zoned HVAC system can put an end to these by allowing individuals to adjust the temperatures independently for each part of the home.
  3. Even temperatures: A zoned HVAC installation can help compensate for hot and cold spots in the home. This system will address your heating and cooling needs by zone, so areas that are naturally colder can get the extra heat they need without pumping excess heat into warm spots as well.

Benefits of zoned HVAC systems

Instead of setting one temperature for your entire house, Arzel zoning, hvac zoning system manufacturer,  can create as many as four temperature-controlled “zones,” so you don’t waste energy overheating or overcooling other areas. In fact, when used with a programmable thermostat, zoning can mean energy savings of up to 35%.* An iComfort® programmable thermostat even lets you adjust the temperature in any zone remotely with a smartphone or tablet.

Zone heating and cooling will give you a new level of control over your home’s heating and cooling. With individual zones in place, you can manage comfort levels in your Waverly Hall, Georgia, home like never before. Here’s everything you need to know about HVAC zoning.

Is a zoning system right for your home?

Almost every household can benefit from a zoned HVAC system. That’s because most homes have a room that’s always too hot or too cold, and family members with different temperature preferences. Zone air conditioning or zoned heating system (zoning systems) allow you to accommodate those different comfort needs, while also helping you save energy.

You should also consider zoned HVAC if you have large windows in your home, a top floor that’s always warmer than lower floors, rooms that you seldom use or that feel stuffy, or special areas like a home office or gym that need additional cooling.

Is a Zoned System Right for Me?

We can install a zoned HVAC system in any home with ductwork. However, this system isn’t the best option for every homeowner. Zoned heating and cooling, hvac zone dampers work best in larger homes where there’s plenty of space to separate into zones. Some families benefit from zoning more than others because the architecture of their home naturally lends to varying temperatures.

You’ll get the most out of HVAC zoning if you have one or more of the following:

  • A two-story home.
  • A basement.
  • An attic living space.
  • Cathedral ceilings.
  • A living space over your garage.
  • A sunroom.
  • Several large windows in the house.
  • A wide layout with two or more wings.

Alternatives to Zoning

A  is just one option for personalized comfort levels in your home. An alternative you might want to consider is a ductless heating and cooling system or zone damper. A ductless system utilizes several air handlers situated throughout the house to manage temperatures. A single outdoor unit can connect to multiple indoor units. Each indoor unit operates independently with its own thermostat.

This system allows you to turn heating and cooling off right at the air handler located in each part of your house. The effect is similar to a ducted zoned HVAC system.
