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.
York HVAC
York is a name you’ve probably heard before—especially if you’ve ever set foot in a commercial building or sports arena, where its massive rooftop units are practically iconic. But on the residential side, York has been quietly building a reputation for dependable comfort and accessible innovation. With a catalog split into the premium Affinity™ series and the more value-driven LX series, York gives homeowners choices that balance efficiency, technology, and price.
What sets York apart is its roots in large-scale systems: when a brand engineers equipment for stadiums, you can expect durability and reliability to filter down into the products designed for homes. Of course, not everything is perfect—York has fewer flagship “flashy” models compared to Carrier or Lennox, and some homeowners have reported dealer support inconsistencies. Still, when installed by a qualified contractor, York delivers steady, efficient performance backed by solid warranties.
