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.
Armstrong Air HVAC
Armstrong Air may not have the same name recognition as others, but among contractors, it’s known as a premium, professional-grade brand that combines Lennox engineering with its own innovations. Manufactured under Allied Air Enterprises, Armstrong Air benefits from Lennox’s R&D resources while carving out a niche as a contractor-preferred brand with strong support and durable products.
For this review, I’m focusing on three flagship products: the A97MV Modulating Gas Furnace, the SCU23LX Air Conditioner, and the 4SHP23LX Heat Pump. Together, they represent Armstrong Air’s top-end lineup, showcasing high efficiency, inverter-driven technology, and smart control integration. In my field experience, it appeals most to homeowners who rely heavily on contractor recommendations and want premium comfort without the marketing markup of more famous brands.
