Carrier HVAC

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.

Trane HVAC

Founded in 1885, Trane has long been recognized as one of the most durable and performance-driven names in the HVAC industry. With a reputation built on rigorous testing and engineering, Trane systems are often the choice for homeowners in regions where extreme heat, humidity, or cold put HVAC equipment to the test. Over the years, I’ve installed and serviced countless Trane systems, and I’ve consistently seen them hold up where lesser brands begin to struggle.

For this review, I’ve chosen three residential ducted products that best represent Trane’s current engineering leadership:

  • Trane S9V2-VS Gas Furnace – a high-efficiency, variable-speed furnace for steady, even heat.
  • Trane XV20i TruComfort™ Variable-Speed Air Conditioner – the brand’s flagship central AC with exceptional humidity control.
  • Trane XV20i Variable-Speed Heat Pump – an all-season comfort solution with strong performance in both cooling and moderate heating.

These models reflect the top end of Trane’s offerings in each category and have been selected based on real-world performance data, field testing, and customer satisfaction feedback.
