Infinity Series 59TN6
Backed by the intelligent Infinity control and a variable-speed blower, this furnace will run in low stage up to 90% of the time. Longer low-stage run times give you better energy efficiency, better temperature control and increased comfort. It also assures you quieter performance.
Variable-speed blower operation also aids other system components and can help make your air conditioning system more efficient and improve summer dehumidification.
