355CAV Plus 90i™ Evolution™ Series - 96% AFUE Multi-Poise Variable-Speed Furnace

The Plus 90i™ sets the standard for home comfort. This unique combination of 2-stage gas valve, variable speed inducer motor, variable speed blower motor, and a patented, intelligent electronic control center offer the ability to adapt to changing needs within the home. The Plus 90i™ offers efficiencies from 92.7% to 96.6% AFUE depending on model and operating position. Electrical consumption is reduced to less than that of a 100 watt light bulb in low heat and continuous fan. Combined gas and electrical usage make the Plus 90i™ the most energy efficient line of furnaces you can buy-saving home owners money all year long.
