Commercial HVAC System

The SunSource® Commercial Energy System from Lennox is the first and only HVAC commercial HVAC system to integrate directly with solar power. The SunSource system collects free, clean energy from the sun and feeds it directly into Lennox’ solar-ready Energence® rooftop unit; excess electricity is used to power other electric devices or is sent back to the power grid. Designed to reduce energy spending and emissions, the SunSource system can provide effective efficiency levels of up to 34 SEER and beyond.
