Two-stage heating for always-on performance

While most furnaces are either off or on, the SL280V can actually deliver two different levels of heat based on how cold it is outside.  This lets it fine-tune fuel use to carefully match your comfort, keeping your home warm and energy-smart.

My house after upgrading to Lenox is now more evenly heated in a much shorter run time. Amazing and toasty warm (even in southern california).

Problematic Unit

July 17, 2022

Installed this heater with outdoor ac unit el16xc1 in May 2021. Immediately disliked a whistle and jet like roar on low stage ac blower. Heater blower noise is ok. The inducer motor went this year. The ac unit had to be completely replaced a month ago due to sporadic loss of refrigerant (3 house calls needed to determine problem).
