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.
Bryant HVAC
With a legacy dating back to 1904, Bryant has become a household name in residential HVAC, known for balancing performance, durability, and comfort. Over the years, I’ve worked hands-on with Bryant systems in both installations and service calls, and the brand consistently delivers solid results across a variety of climates. Their Evolution™ series-the premium line-represents the highest level of their engineering, offering precise temperature control, advanced humidity management, and quiet, efficient operation.
For this review, I’m focusing on three core residential ducted products that I’ve personally tested and that reflect Bryant’s capabilities across heating and cooling:
- Evolution™ 98 Gas Furnace (987M) - a fully modulating, high-AFUE furnace for cold climates.
- Evolution™ Extreme Variable-Speed Air Conditioner (191VAN) - a flagship central AC designed for maximum comfort in hot, humid conditions.
- Evolution™ Extreme Variable-Speed Heat Pump (284ANV) - a year-round system offering both heating and cooling efficiency.
These choices aren’t just based on spec sheets-they’re selected because they perform well in real homes, with feedback from homeowners that aligns with my own field experience.
