Carrier vs Lennox
Lennox pushes peak efficiency further than any other residential brand. Carrier is more widely supported by independent dealers and easier to service long-term.
Lennox and Carrier are the efficiency leaders of the premium tier. Lennox's Signature Collection — SL28XCV AC and SL280V furnace — is the highest-SEER2 residential equipment sold in the U.S. Carrier counters with the Infinity 24 AC and Infinity 98 furnace, slightly behind on peak numbers but with a denser independent dealer network across Minneapolis–St. Paul.
Side-by-side specs
| Criterion | Carrier | Lennox |
|---|---|---|
| Top-tier AC SEER2 | Up to 24 SEER2 (Infinity 24) | Up to 28 SEER2 (SL28XCV) |
| Top-tier furnace AFUE | 98.5% (Infinity 98) | 99% (SLP99V) |
| Parts warranty (registered) | 10-year parts limited | 10-year parts limited |
| Compressor design | Two-stage / variable Greenspeed | Variable-capacity SilentComfort |
| Independent dealer network (metro) | Strong, multi-dealer | Quasi-exclusive Premier Dealers |
| Service-part availability | Stocked locally | Often dealer-only, longer lead times |
| Humidity control | Infinity Touch w/ dehum mode | iComfort S30 active dehumidification |
| Typical Twin Cities install cost (furnace + AC) | $14,000–$18,500 | $15,500–$22,000 |
The verdict
Lennox wins on raw efficiency and humidity control, but the Premier Dealer model can make out-of-warranty repairs slower and more expensive. Carrier gives up 2–4 SEER2 points but is materially easier to live with at year 12.
Pick Carrier if…
- You value long-term serviceability and shorter parts lead times.
- You want premium efficiency without locking into one dealer.
- You expect to sell within 10 years — recoup on lower install cost.
Pick Lennox if…
- You're optimizing for absolute lowest utility bills (SL28XCV pays back in larger homes).
- Humidity control is a real comfort issue in your home.
- You have an established relationship with a Lennox Premier Dealer.
