Efficient rooftop units

The Energence rooftop line features a multi-stage air volume (MSAV) supply fan and feature a belt-less blower system that is designed to reduce maintenance.


Lennox's Energence ultra-high-efficiency rooftop line feature efficiencies of up to 21.5 IEER and 13.9 EER and are designed to exceed ASHRAE Standard 90.1 requirements as well as CEE Tier 1 and 2 efficiency requirements. Energence ultra-high-efficiency models come standard with MSAV (multi-stage air volume) supply fan technology and has an optional feature with the belt-less DirectPlus blower system. The DirectPlus blower system combines the motor and electronics into one unit, which uses fewer components and features slide-out access to help reduce maintenance time and costs. The Energence units are backwards compatible with many existing Lennox rooftops, which makes replacement applications simpler.
