Lennox HVAC

Lennox HVAC main picture

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.

Ruud HVAC

When discussing reliable American HVAC brands, Ruud often comes up as a sibling to Rheem—both share engineering roots but maintain their own dealer networks and product branding. For homeowners, Ruud positions itself as the “no-nonsense comfort” option: systems that aren’t overloaded with gimmicks, yet deliver consistent heating and cooling performance.

In this review, I’ll focus on the U98MV Endeavor Line Prestige® Gas Furnace, the UA19AY Air Conditioner, and the UP19AY Heat Pump. These three models represent Ruud’s top-tier offerings, combining efficiency, durability, and smart connectivity. If you’re wondering how Ruud stacks up against its better-known rivals like Lennox or Carrier, keep reading—there are strengths here worth noticing, along with a few areas where Ruud takes a more conservative approach.
