Lennox is a forward-thinking company that specializes in innovative technologies that maximize efficiency and minimize noise. With 20 different furnace models available and expert representatives, Lennox has consistently earned recognition as a brand of excellence. 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.
Types of Lennox Furnaces

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. 
Lennox Furnace ModelsLennox offers furnace options to fit various budgets, heating requirements, and energy-efficiency preferences. Below are the top 10 Lennox furnace models.

SLP98VThis energy-efficient Lennox furnace is the company's flagship gas furnace and has an industry-leading AFUE rating of 98.7 percent. This heating system was named one of the most efficient Energy Star-certified products of 2019.
This quiet unit has two heat exchangers and condensing technology, which provides effective heat dispersement. The modulating valve and a variable-speed blower improve performance, and according to Lennox, the unit's silicone nitride ignitor increases its durability and reliability. The system runs on natural gas and is compatible with the Lennox smart thermostat.
SL280VThis popular furnace has an AFUE rating of 80 percent. With two-stage heating and a variable-speed motor, this model provides efficient heating. The system uses Lennox's proprietary SilentComfort technology, and sound-absorbing insulation further quietens operation. This natural-gas heating system is compatible with Lennox's smart thermostat for automatic temperature control and remote access.
