Carrier HVAC

Carrier HVAC main picture

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.

Amana HVAC

Amana HVAC main picture

Amana has been around since 1934, originally known for appliances but now established as a trusted U.S. HVAC brand under Daikin Industries. While it shares engineering DNA with Goodman, Amana is positioned as the premium sibling: the same Daikin-built cores, but with enhanced design, extra warranty protection, and slightly more refined finishes.

For this review, I’m focusing on three flagship Amana models: the AMVM97 Gas Furnace, the ALXT7C Air Conditioner, and the AZV7S Heat Pump. Together, these represent Amana’s strongest offerings across heating and cooling. In my field experience, Amana appeals to homeowners who want reliable comfort backed by the industry’s most generous warranties—particularly the lifetime unit replacement coverage, which remains one of the boldest guarantees in the HVAC market.
