Types of Zoning Systems

Duct Mounted Zoning (no bypass) - not recommended
 The best way to describe this type of zoning is “shoddy”. Do you have any heat registers closed in your home? If you do, this system is basically like closing of registers to a variaety of rooms in the home if you do not desire heating or cooling in those places. The difference between this and typical zoning systems is that while a advanced zoning system will turn the furnace on and off even if it is just the bonus room that needs heat, this system can only zone if the main room thermostat has activated the furnace. As well, just like closing your registers, this is an easy way to limit the life span of your furnace. This system is an example of an "over deliver / under perform" scenario.

Forced Air Zoning System (with bypass)
There are many brands of this type of zoning system, we have chosen UltraZone, but that does not mean there are not others that will do the job well, like Honeywell. The Forced Air Zoning System uses motorized dampers in your duct work that open and close as needed based on each zone's thermostat settings. The damper system will control the airflow through the duct work and deliver only the desired air to the desired location. Each thermostat has the ability to turn on and shut off the heating and cooling supply in it's zone. When a zone doesn't need to be heated or cooled, the dampers close to save energy and maximize comfort elsewhere. It's that simple. This system does require a bypass or blow-off valve to allow excess air not being used by the zoning system to cycle back to the furnace. These types of systems are generally used in conjunction with Honeywell thermostats.

Carrier Infinity Forced Air Zoning System
While there are many types of forced air zoning, there is only one Infinity System. This zoning system is so advanced that it has the ability operate without a bypass, giving you, hands down, the most efficient zoning system available. Automatically communicating with all the heating, cooling and air cleaning components attached to it, the Infinity Zone Control is so easy to use it makes installing and using a standard forced air zoning system seem like rocket science.
