Compatible with/Replacement for Suburban Manufacturing - 2450A - NT-20SQ 19 000 HEATER

The "Q" stands for "QUIET." Suburban Q Series furnaces have been redesigned to be significantly quieter. Increasing the efficiency of the furnace blower to deliver more CFM, allowed Suburban Design Engineers to lower the motor RPM to deliver the same amount of air but at a substantially lower sound level. Why "talk over" the furnace when you don't have to with the Suburban Q Series furnace.
