Lennox HVAC
Among the major names in HVAC, Lennox stands out for its long heritage and reputation for pushing the limits of efficiency. For this review, I focused on three cornerstone products that reflect the brand’s residential ducted portfolio: the SLP99V Gas Furnace, the SL28XCV Variable-Capacity Air Conditioner, and the XP25 Variable-Capacity Heat Pump. Together, these models showcase what Lennox brings to homeowners who demand consistent comfort, low energy bills, and technology that balances innovation with real-world reliability. Over years of field testing and speaking with homeowners, I’ve seen both the strengths and the areas where Lennox could improve, and this review reflects that balance.
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.
