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.
Daikin HVAC
As the world’s largest HVAC manufacturer, Daikin brings a global engineering pedigree to the U.S. residential market. Known worldwide for its ductless mini-split systems, Daikin has also invested heavily in its residential ducted lineup, blending the reliability of American furnace traditions with advanced inverter-driven cooling and heating technologies.
For this review, I’m focusing on three flagship models from Daikin’s current catalog: the DM97MC Modulating Gas Furnace, the DX9VC Air Conditioner, and the DZ9VC Heat Pump. Together, they showcase how Daikin applies its international expertise—variable-speed compressors, precise modulation, and advanced comfort controls—to traditional U.S. home HVAC systems.
In my field experience, Daikin systems often appeal to tech-forward homeowners who value cutting-edge efficiency and smart features, but also want dependable heating and cooling that fits seamlessly into ducted homes.
