Zone Control For Heating and Cooling

Let’s face it, our houses are bigger than ever before. And we like it that way. It’s nice having a home theater for the weekends; a guest bedroom for when family arrives into town. The extra space is something we need to do all the things we like to do.

But it takes a lot to heat and cool all of that space too.

It’s easy to look at a wing of your home and wonder why you’re heating or cooling it at the same rate as the rest of your house. Why not close off a room, shut the door or turn the louvers to prevent conditioned air from entering? Without having the conditioned air flow through a room, you’ll save money, right?


It can be a smart idea to be able to close off some of the rooms from the ventilation system, so you don’t have to heat or cool empty rooms. But there is a method to getting it done the correct way. That’s where zone control systems come into play.

When you simply shut down a vent and control the louvers, it doesn’t stop the airflow to that space. The pressure builds inside the ductwork, and this, in turn, forces the HVAC blower to work harder. Which means you’ll see your utility bills increase instead of decrease, and it can even damage the furnace or the AC.

Zone controls are designed to close off parts of the house from the HVAC system while lowering the amount of energy used and preventing increases in pressure. You need:

  • Dampers in the ducts to seal and cut off a stretch of ductwork as needed
  • Zone thermostats to control each climate zone
  • Variable speed blower fan to alter pressure changes inside the ducts
  • A central thermostat to operate the fan and each of the dampers

With all of the parts for a zone control system in place, you’re ready to start saving money with your zone control HVAC system.

This means you can control heat and AC, allowing it to go to specific places in your home.

The central thermostat checks for zones that aren’t requesting heat or air, and closes those dampers. The blower fan adjusts to maintain pressure.

When the zoned thermostats reach their target temperatures, the central thermostat closes off their dampers.

When all zoned thermostats are fulfilled, the central thermostat shuts off the heater and blower, then allows any excess air to leave the system.
