| Feature | 59MN7 | 59TP6 |
|---|---|---|
| AFUE | Up to 98.5% | 96.5% |
| Heating | Modulating | Two-Stage |
| Blower | Variable-Speed | Variable-Speed |
| Installed Cost | $7,500–$8,100 | $5,000–$5,600 |
As Carrier’s flagship model, the Infinity 98 commands the highest price. By contrast, the Performance 96 – 59TP6 is more affordable, typically ranging from $5,000 to $5,600 installed.
While you’ll sacrifice some efficiency and performance, the Performance 96 still offers impressive features — including a two-stage burner, variable-speed blower motor, secondary heat exchanger, and 96.5% AFUE rating.
For many homeowners, the Performance 96 provides a strong balance of value, comfort, and efficiency at a lower cost.
Verdict: The 59TP6 offers strong comfort at a lower price, but the 59MN7 delivers superior efficiency and precision control.
| Feature | 59MN7 | 59SC2 |
|---|---|---|
| AFUE | 98.5% | 92.1% |
| Heating | Modulating | Single-Stage |
| ENERGY STAR® | Yes | No |
| Installed Cost | $7,500+ | $3,800–$4,800 |
The Infinity 98 sits at the top of Carrier’s lineup, while the Comfort 92 – 59SC2 represents the entry-level option. The Comfort 92 is a single-stage furnace with a multi-speed blower and 92.1% AFUE.
However, it lacks compatibility with Carrier’s advanced technologies and doesn’t meet Canada’s minimum 95% efficiency requirement, making it unsuitable for most modern homes. It offers less comfort, higher operating costs, and reduced humidity control compared to the Infinity 98.
Verdict: The Infinity 98 vastly outperforms the Comfort 92 in efficiency, comfort, and long-term savings.
| Feature | 59MN7 | 59TN6 |
|---|---|---|
| AFUE | Up to 98.5% | 96.7% |
| Heating | Modulating | Two-Stage |
| Smart Tech | Greenspeed® | Infinity Control |
| Installed Cost | $7,500–$8,100 | $6,000–$6,600 |
The Infinity 96 – 59TN6 is another premium option, though not as advanced as the Infinity 98. It features a two-stage burner instead of a modulating one and delivers a slightly lower 96.7% AFUE.
While energy savings will be similar, the Infinity 96 lacks Greenspeed Intelligence, which gives the Infinity 98 a clear edge in comfort precision and efficiency optimization.
If you want:
Maximum efficiency
Ultra-precise comfort
Quiet operation
Long-term energy savings
The 59MN7 is Carrier’s best furnace investment. While expensive upfront, it delivers top-tier performance and potentially lower lifetime operating costs.
The Carrier Infinity® Greenspeed® 98 – 59MN7 is the pinnacle of Carrier’s furnace technology. With 98.5% AFUE, full modulation, and Greenspeed® Intelligence, it offers unmatched precision, comfort, and efficiency.
For homeowners seeking the absolute best performance — and willing to invest in premium technology — the 59MN7 stands as one of the strongest high-efficiency furnaces on the market.
