The second floor of your home gets too hot, and your downstairs feels too cold from trying to cool the upstairs—you need a zone control system.
You like one temperature, your spouse prefers a different setting. And your kids complain it’s too hot—HVAC zoning is the answer.
A zone control system is the perfect solution for homes with multiple floors or sprawling layouts. With zoning, you create different temperature zones under the same roof, reducing your energy use and lowering utility bills. Homes with concrete slab foundations, large windows, high ceilings, or finished rooms in the attic or basement are good candidates for a zone control system.

About Zone Control Systems
Creating a zone control system in your home is no DIY job. Our NATE-certified professional understand how to install the mechanical dampers, thermostats, and remote-control board to make it work. You might think closing and opening vents creates HVAC zoning. It does not—your HVAC system is still working at full speed, creating stress on your equipment.

Zone Control Installation
Our heating and cooling specialists will install dampers in your ductwork and mount a control panel near your furnace or air conditioner. Thermostats are placed in each zone. Turn your second floor into one zone, your downstairs into a second zone, and the master bedroom into a third one.
When you adjust each thermostat, the control panel opens or closes dampers to distribute hot or cold air where it is needed. Set the thermostats in each zone, and relax. Plus, you can control the thermostats using your smartphone or tablet.
Opening and closing registers throughout your home will not create a zone control system because adjusting the registers does not cause your furnace or air conditioner to produce less hot or cold air. Closing the registers could contribute to leaky ductwork and low airflow.
By comparison, a zone control system not only redistributes airflow by operating dampers but also controls your HVAC system, telling it when to run and when to shut down, which eliminates unnecessary energy expenses.

Frequently Asked Questions
Yes, adding zoning to an existing HVAC system is possible, but it depends on your current system and the type of zoning you’d like to implement. Sometimes, adjustments to your ductwork may be required, as well as the installation of new thermostats and dampers.
