The top of the Infinity 96 family delivers 117,000 BTU/h on high fire from 120,000 BTU/h of input, with low fire at 78,000 BTU/h input and 76,000 BTU/h output. Its certified 96.7% AFUE upflow and horizontal ties the 080C21–20 for the family's best figure; downflow certifies at 95.0%.
At 195 lb with a 24.5-inch cabinet, six burners, a 1 HP communicating blower and a factory-supplied 24-inch media cabinet, this is a large appliance that needs a mechanical room and a duct system built for it. The blower moves 1,820 CFM in high heat and up to 2,135 CFM for cooling.
In the Lower Mainland this size appears most replacing an old large furnace in a big older house where the heat-loss calculation confirms the capacity. Carrier's product data repeats the standing warning that excessive oversizing can shorten furnace and vent life; the calculation decides, not the old furnace.

Questions people ask
Does the Infinity 96 come any larger than this?
No. The 59TN6B family has five sizes ending at the 120C24–22. Larger communicating capacity sits in the Infinity 97 and Infinity 98 families at similar cabinet sizes.
Why does the largest size match the 96.7% figure of the 080C21–20?
Certified AFUE is per size, not per cabinet: Carrier publishes 96.7% for both the 080C21–20 and the 120C24–22, with 96.3%, 96.2% and 96.1% on the other sizes.
