What is heating and air conditioning zoning and zoning control?  “Zoning” and “zone control” of HVAC systems are individual temperature control from one central heating and air conditioning system. Typically, with almost all 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 heating and air conditioning 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 is a professionally installed zone 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 heating and air conditioning system.

To understand why zoning makes sense, think of it as if you have 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.


Benefits of Heating & Air Conditioning Zoning

If you are only living in or occupying one room or zone of your house, why heat or cool the entire house?   Here are some benefits of HVAC zoning systems:

Enhanced comfort
One thermostat centrally located in a hallway, dining room or even the living room cannot properly control the temperature in any other area than the area nearest the thermostat.  If you have a multi-level home it’s very hard to control the temperature on the second floor when the thermostat is on the first floor.

There are many factors that affect the indoor temperature in your home. Outdoor conditions such as solar gain, wind chill, shading, cathedral ceilings, multilevels, below grade rooms and internal factors such as fireplaces, heat from lights, cooking, appliances, etc., all affect the temperature throughout the home.  Zoning solves these problems by allowing each zone’s thermostat to make the demand individually.  Zoning improves the overall comfort by allowing the zone thermostats to react to changes in temperature in each zone.

Energy efficiency
A zoning system increases the energy-efficiency of any heating and air conditioning system.  Zoning allows you to set back thermostats in zones not being used and prevents zones from becoming over heated or cooled while other zones are not yet comfortable.  Homeowners have reported as much as 20% to 30% savings in energy costs using zoned systems. These results in tests can be greater when combined with programmable thermostats allowing multiple setbacks each day.

A zoning system allows you to set the temperature in the room or zone you’re in and not have to go to another area of the home to change the temperature.  If you’re in the bedroom at night ready to go to bed, you can adjust the temperature you want right there without having to go to the living room or some other area.  You can rest assured that you are only conditioning your bedroom zone and not all other areas of the home.
