How A Heating & Cooling Zoning System Works

HVAC Zoning

Zoned Heating and Cooling Controls Temperature and Lowers Utility Bills.

A zoned heating and cooling system allows your furnace and air conditioner to use dampers in the ductwork to direct air to specific areas when needed. Zoned systems help you use your heating and cooling more effectively by distributing air where and when it is needed. Zoning can improve comfort and lowers utility bills up to 35% with a programmable thermostat according to the US Dept of Energy.

Is HVAC zoning right for you?

A typical zoned heating system treats the main floor as one heating zone and the upstairs as a separate heating zone. This allows heat to be directed to the main floor during the daytime and to the upstairs bedrooms at night, allowing unoccupied areas of the home to cool down when vacant.

Do you have some rooms that are cooler or warmer?  Does your home have two or three levels, large windows, rooms that you seldom use? Ideally, your entire home should stay about the same temperature. But insulation, duct size, window size, sunshine, room size, ceiling heights, room location all influence your comfort.

By dividing your place into two or more zones, your HVAC system can deliver more comfort. Zoning helps eliminate temperature inaccuracies from using only one thermostat sensor point. That means people in different areas can adjust their own thermostat and temperature to meet their needs. Especially true if you like to keep your bedrooms warmer at night, while the rest of your home is cooler. Now you can turn off zones when no one is using them, especially at night.

One thing is certain.

Don’t try to install an HVAC zoning system if your building has problems. Problems like poor insulation or air leaks from windows.

Your zoned system contains 4 main components:

  • Control panel— is installed at your furnace and reads the different thermostats and triggers the dampers to open or close.
  • Duct dampers—HVAC zoning dampers are the valves in your ducts that open and close. Two zones are common but you can do four zones or more for commercial.
  • Zone thermostats—Yes, each zone gets a thermostat to send messages to the control panel.
  • Multi-stage furnace, variable-speed blower—When there is less heat needed, this type of furnace can adjust to a lower setting.

Zoned heating & cooling savings and comfort.

The average household spends 40% on energy bills for heating and cooling costs (about $2200). You won’t waste energy overheating or overcooling certain areas of your home or business.
