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.
Coleman HVAC
Coleman may be best known for its camping gear, but in HVAC, it’s part of the Johnson Controls family, sharing engineering DNA with York and Luxaire. While smaller in market share than Carrier or Trane, Coleman positions its Echelon® series as a premium residential lineup that combines reliability, efficiency, and installer-friendly design.
For this review, I’m focusing on three flagship models: the CP9C Gas Furnace, the AC21 Air Conditioner, and the HC20 Heat Pump. Together, they demonstrate Coleman’s ability to deliver modern HVAC solutions with modulating, variable-capacity technology that rivals the bigger names. In my field experience, Coleman often appeals to homeowners who want premium comfort at competitive prices, especially in regions where local Johnson Controls dealers are strong.
