Carrier Comfort 96 vs Performance 96 single-stage: the 60,000 BTU/h furnaces
A same-size comparison of Carrier's two single-stage 60,000 BTU/h furnaces — the Comfort 96 (59SC6A) and the single-stage Performance 96 (59SP6B) — from Carrier's published product data.
Short answer
The Comfort 96 (59SC6A 060M17–16) and the single-stage Performance 96 (59SP6B 060V17–16) are Carrier's two single-stage 60,000 BTU/h condensing furnaces. Both deliver 58,000 BTU/h at one gas rate, but the Performance certifies 97.0% AFUE upflow versus 96.5% for the Comfort, adds the 3-digit display with InteliSense capability and the variable 25-speed blower, and costs more. The Comfort is the entry furnace; the Performance single-stage is the step above it.
| Specification | 59SC6A 060M17–16 | 59SP6B 060V17–16 |
|---|---|---|
| Input | 60,000 BTU/h | 60,000 BTU/h |
| Output capacity | 58,000 BTU/h | 58,000 BTU/h |
| AFUE, upflow / horizontal | 96.5 % | 97 % |
| AFUE, downflow | 95 % | 95 % |
| Cabinet width | 17.5 in | 17.5 in |
| Shipping weight | 142 lb | 144 lb |
| Airflow, heating @ rated ESP | 1,030 CFM | 1,030 CFM |
| Cooling airflow range | 315 – 1580 CFM | 345 – 1565 CFM |
| Blower motor | 3/4 HP | 3/4 HP |
| Maximum unit amps | 10.1 A | 10.1 A |
| Maximum fuse / breaker | 15 A | 15 A |
Heating output is identical at full fire: 58,000 BTU/h from a 60,000 BTU/h input on both, with certified temperature rises of 40 to 70 °F. The difference is efficiency and equipment: Carrier certifies the Performance single-stage at 97.0% AFUE upflow versus 96.5% for the Comfort, with 95.0% downflow and horizontal on both.
The blower families differ in name but not in kind: the Comfort uses Carrier's multi 18-speed constant-torque ECM and the Performance single-stage uses the variable 25-speed constant-torque ECM. Both are non-communicating ECM motors with installer-selectable speeds; neither reports airflow back to the control.
The Performance single-stage adds the current-generation 3-digit display control with InteliSense capability, ComfortFan control and the same control platform as the two-stage Performance furnaces; the Comfort 96 uses the same 3-digit display generation but without InteliSense communications. Both carry the 15 A maximum breaker in this size.
For a simple, efficient single-stage replacement, the Comfort 96 is the lower-cost answer; the Performance single-stage earns its premium through the 97.0% certification point and the shared Performance control platform. Neither has a low-fire stage, so sizing from a heat-loss calculation matters more than the tier badge.
Questions people ask
Which single-stage Carrier furnace is cheapest?
The Comfort 96 is Carrier's entry tier. The single-stage Performance 96 costs more and certifies one efficiency point higher (97.0% versus 96.5% upflow in this size) with the Performance controls.
Do both furnaces run at full fire on every call?
Yes, both are single-stage: one gas rate, on until the thermostat is satisfied. That is the trade-off both make against Carrier's two-stage furnaces.
