We all want our homes to be as comfortable as possible. An HVAC zoning system, also called a “zoned HVAC” is a heating and cooling system that uses dampers in the ductwork to redirect and regulate air to certain areas of the home. It’s a great system if you want to customize temperature zones throughout your home to improve comfort and efficiency.
Will a 2 or Dual Zone System Work in Your Home?
Because most homes have rooms that are too hot or too cold, almost any home can benefit from a zoned HVAC system. Most homes also have family members that want a different temperature than the rest of the family. Again, a zoned system can help. Different needs can be accommodated with a zoning system and it will save you some money in energy costs. Consider using a zoned system if you have large windows in your home, a top floor that seems to be warmer than lower floors, a room you rarely use, a room that feels stuffy or you have a room that needs extra cooling, like an office or a gym.
Multi Zone Heating & Cooling Systems
A zoned system will control different “zones” in your home, instead of heating or cooling the entire home. Different temperatures an be set for different section or rooms in your home. Typical forced air systems only have one thermostat for the whole house. Once you switch it on, there really isn’t any way for you to control the temperature in certain rooms. The only way you can attempt to do this is to manually close off outlets to certain rooms. This method of temperature control is not only time consuming but can be harmful to the HVAC unit. When too many outlets get turned off, it can reduce the airflow and cause parts of your HVAC system to wear down prematurely. You won’t have to heat or cool rooms that aren’t used very often. Example, you live in a two-story home and are rarely upstairs. A zoned system will have a damper and thermostat for each room or zone in your home.
How Does Adding a Zone to Your HVAC System Work?
Zoning is accomplished through a series of components, the first are motorized dampers that will open and close based on the demands of the thermostats set for that zone. These dampers insert into the ducts or they can be installed at each air outlet for each room or zone. The next components are the zone thermostats. Homes that are already built will use the existing thermostat as a zone thermostat. As zones are divided, each zone will use a thermostat to control the heating, cooling and fan operations for the zone it’s attached to. These thermostats and dampers are wired to the central control panel. Think of a zoning system as having a light switch in each room in your home. You wouldn’t have one light switch for every room in your home. The same should go for heating and cooling. Why flip the AC on for the whole house when you only need to cool or heat one room?
