Carrier Performance 96 single-stage 59SP6B 120V24–22
The 59SP6B 120V24–22 is the largest single-stage Performance 96: 120,000 BTU/h input, 116,000 BTU/h output at one gas rate, 96.1% AFUE upflow, in a 24.5-inch cabinet with six burners. It is a specialist size for genuinely large or poorly insulated houses.

The top of the single-stage Performance 96 family delivers 116,000 BTU/h on every heating call from six burners, certified at 96.1% AFUE upflow and 95% downflow and horizontal. At 186 lb in a 24.5-inch cabinet, it is a large appliance that needs a mechanical room and a duct system built for it.
The 1 HP variable 25-speed ECM blower moves 1,955 CFM in heating and up to 2,245 CFM for cooling, and the 20 A maximum breaker with 12 AWG wire suits the draw. 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.
A furnace this size firing at full rate on every call is a blunt instrument for mild weather: if the house rarely needs full fire, the two-stage Performance 96 at the same capacity serves it more gently. Carrier's product data repeats the standing warning that oversizing can shorten furnace and vent life.

Questions people ask
Is there a larger single-stage Performance 96?
No. The 59SP6B family tops out at 120,000 BTU/h input. Larger single-stage capacity is available in the Comfort 96 line (140,000 BTU/h) and in historical Carrier models documented on this site.
Why choose this over the two-stage 120,000 BTU/h Performance 96?
First cost and simplicity. The two-stage version carries most mild-weather cycles on low fire, which is gentler on a large house; if the calculation shows the house genuinely needs 116,000 BTU/h of output, compare both in the proposal.
