Read on to learn about the types of Lennox furnaces available, specifics on 10 of their top models, an overview of pricing and warranty options and what to look for in Lennox furnace reviews.
Most Lennox furnaces run on gas, but some use oil instead. Within those two fuel types, different furnace models offer different features. Different models include variable speed, ultra-low emission, and two-stage furnaces.
Variable speed furnaces prevent large temperature fluctuations and reduce operating costs while providing consistent heating with lower humidity. Ultra-low emission Lennox furnaces burn away more NOx gases and result in cleaner emissions, healthier for you and the environment. Two-stage furnaces offer both high and low output settings that calibrate furnace heat flow to thermostat settings. Furnaces with constant torque motors offer improved efficiency while delivering greater comfort and cost savings.
