Features

Balanced comfort and efficiency

While most furnaces are single stage, meaning they're either on or off, this furnace can heat at two different speeds. Most of the time the unit will meet heating needs at its lower speed, resulting in balanced and consistent temperatures with lower energy use.

The perfect amount of quiet.

Made with a fully insulated cabinet, special sound-absorbing materials and sturdy burners to reduce noise, this furnace is designed to operate extremely quietly, so you can relax in peaceful warmth.

LOWER OPERATING COSTS

• The separated combustion technology enhances overall energy efficiency of the building by eliminating the continued replacement of conditioned air with unconditioned outside air.
• Up to 5% more efficient than standard efficiency direct-fired unit heaters**
• LS25-250 through LS25-400 kBtuh models lower operating costs by efficiently meeting the demands of the space with two stages of heating.

A refrigerant that’s better for the environment.

This product is compliant with 2025 EPA regulations for lower global warming potential (GWP) refrigerants. The Lennox choice of 2025 Compliant Refrigerant has a lower GWP than its predecessor and is formulated to provide excellent, reliable performance of your system for years to come.
