Highlights
Price Snapshot: Mid-to-premium; usually pricier than value brands, below ultra-luxury tiers.
Product Focus: Full lineup across Furnace, Central AC, and Air-Source Heat Pump (strong inverter options).
Best For: Buyers who want very even temperatures and low noise with brand-name dealer support.
What Stands Out: Polished smart thermostat ecosystem that works tightly with variable-speed systems.
Before You Buy: Match the series to climate (consider cold-climate heat pump models where winters are harsh).
Warranty/Dealer: Broad U.S. dealer network; parts coverage is solid; confirm labor options with your installer.
Founded in 1902 by Willis Carrier - the man credited with inventing modern air conditioning - Carrier is one of the most recognized HVAC names worldwide. In my years working with residential ducted systems, Carrier has consistently delivered a balance of innovation, comfort, and durability. The Infinity® series is their flagship line, offering top-tier performance with advanced control systems, variable-speed technology, and strong energy efficiency.
For this review, I’m focusing on three standout products that represent Carrier’s engineering strengths in each major residential ducted category:
- Infinity® 98 Gas Furnace with Greenspeed® Intelligence (59MN7) – Carrier’s most advanced furnace for precise heating.
- Infinity® 26 Air Conditioner (24VNA6) – a flagship AC designed for superior cooling and humidity control.
- Infinity® 24 Heat Pump with Greenspeed® Intelligence (25VNA4) – a versatile year-round option for both heating and cooling.
These units are selected not just for their place at the top of the spec sheet, but because they’ve proven themselves in actual homes, backed by both my field experience and consistent customer feedback.

Conclusion

The Infinity® 98 furnace, Infinity® 26 AC, and Infinity® 24 heat pump represent the top tier of residential ducted performance, capable of keeping a home comfortable in both extreme heat and cold while minimizing energy use.
