Lennox® Zoning Systems | For Complete Control and Unbeatable Comfort

Reduce energy costs by cutting back on heating and cooling unused areas of your home. Lozier Heating and Cooling has two zoning systems that are quality, high-efficiency products to keep the temperature in your home consistent from room to room. These can easily be adjusted for seasonal weather or if your preferences change. Zoning your home can equate to energy savings of up to 35% when used with a programmable thermostat.

Variable speed control.

Variable-Speed Control

Variable speed technology delivers greater control and consistent airflow for improved comfort and air quality inside your home. While low-quality A/C’s are either all the way on or off, variable-speed has different levels of airflow - much like the temperature controls in a car.

Auto changeover.

Auto Changeover

The changeover feature automatically switches between heating and cooling operations based on indoor temperature so you don’t have to remember to switch settings each season.
