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.
Bosch HVAC
Bosch Home Comfort brings over a century of German engineering heritage into the U.S. HVAC market. Known worldwide for precision and efficiency, Bosch has carved a niche in residential HVAC by focusing on inverter-driven comfort solutions and compact designs. In the U.S., Bosch offers both traditional gas furnaces and advanced ductless heat pump systems, giving homeowners flexible options depending on their climate and home setup.
For this review, I’ll focus on the Bosch BGH96 Gas Furnace, which offers high-efficiency heating with a quiet, dependable design, and the Bosch Climate 5000 Ductless Mini-Split Heat Pump/AC, which showcases Bosch’s strength in inverter-driven, variable-capacity technology. Together, they highlight Bosch’s dual focus: combining American-style furnaces with global expertise in ductless and heat pump technology.
