Don't 'FREEZE' Call D's...What Is HVAC Zoning?
Stop Heating and Cooling Rooms You're Not Using
HVAC zoning divides your home into separate temperature-controlled areas — each with its own thermostat and motorized dampers in the ductwork. When one zone calls for heating or cooling, only the dampers for that zone open. The rest stay closed. You condition only the rooms you're using, which cuts energy waste and eliminates the hot-upstairs, cold-downstairs problem that plagues most Chicago two-flats and multi-level homes.
D's Air & Heating, Inc. installs the full Lennox zoning lineup — from the entry-level LZS1 two-zone panel to the fully communicating Lennox Smart Zoning System that integrates with iComfort S40 and S30 thermostats and variable-speed equipment for precise, room-by-room comfort control.
Lennox Zoning Lineup
3 Systems. Every Home Size.
Lennox Smart Zoning System
Communicating Zoning Platform
The Lennox Smart Zoning System is a fully communicating zoning platform designed to work seamlessly with Lennox iComfort S40 and S30 thermostats. It divides your home into up to four independent comfort zones, each with its own thermostat and damper control — so every room stays at exactly the temperature you want.
LZS2 Four Zone System
Four Zone Control Panel
The Lennox LZS2 is a four-zone control panel compatible with multi-stage heating and cooling equipment. Ideal for multi-level homes, homes with multiple occupants, or any application where upstairs and downstairs temperature control is needed independently.
LZS1 Two Zone System
Two Zone Control Panel
The Lennox LZS1 is a two-zone control panel — the most straightforward way to add zoning to a conventional single-stage HVAC system. Perfect for ranch homes, split-level homes, or any home where main floor and basement temperature control is the primary goal.
