Explore Zoning Solutions for Your Home


An Environment Exactly How You Want It

Every heating and cooling system moves air through your home. But a Lennox® zoning system such as iHarmony® uses motorized dampers in your ducts to reduce or increase airflow to different parts of your home, making sure they’re kept just how you want them.

Greater Control Over Heating and Cooling

A Lennox® zoning system divides your home into as many as four “zones,” giving you more options for controlling your family’s comfort and your home’s energy usage.

Use Your Phone to Control Zones Remotely

When you combine an iHarmony zoning system with an iComfort® thermostat, you can adjust the temperature in any zone remotely with your smartphone, tablet or other web-enabled device.

Smarter Use of Energy

By directing air to where it’s needed most, a Lennox® zoning system doesn’t waste energy overheating or overcooling other areas.

Your Comfort, Your Way, Every Day

Lennox® zoning systems let you create your comfortable environment, your way. Depending on the size of your home, up to 4 different zones can be established, and you can customize settings according to your needs.

A Lennox® zoning system directs air to specific areas of your home, keeping it perfectly comfortable and energy efficient. From the precise climate control of an iHarmony® whole-home zoning system to the room-by-room control of an LZP-2 zoning system, Lennox® gives you lots of ways to customize your home’s comfort. An iHarmony four-zone system delivers perfect temperature control throughout your home. Using a series of motorized dampers in your ductwork, the system directs air through the ducts to specific areas, while reducing air flow in others. When paired with an iComfort® S30 Ultra Smart Thermostat, each zone can be remotely controlled via a smartphone app. An iHarmony zoning system can help you save energy, especially when coupled with a programmable thermostat. An LZP-2 zoning system divides your home into two temperature-controlled zones. You can turn up the heating or cooling in one area and lower it in another, depending on your needs. An auto changeover feature automatically alternates between heating and cooling during transitional weather to deliver enhanced comfort and energy efficiency in any season. An LZP-2 zoning system works with your HVAC system to maintain your desired temperature in each zone, delivering year-round comfort and energy savings.
