Goodman HVAC
For decades, Goodman has been known as the HVAC brand that delivers straightforward, affordable comfort systems without the luxury pricing of top-tier competitors like Carrier or Lennox. Founded in 1975 and now part of Daikin Industries, Goodman benefits from global R&D while still focusing on value-oriented systems built for the American residential market.
In this review, I’ll focus on three key models that showcase Goodman’s capabilities: the GSXC7 Air Conditioner, the GSZC7 Heat Pump, and the GMVM97 Gas Furnace. These units represent the upper end of Goodman’s residential offerings, combining competitive efficiency, reliable performance, and some smart technology integration through ComfortBridge™.
While Goodman has historically been seen as a “budget” brand, its recent lineup demonstrates significant improvements in quality, efficiency, and warranty coverage. Still, it’s worth noting that Goodman’s reputation remains closely tied to installation quality—when properly installed, these systems can perform exceptionally well, but poor installs are more common at this price tier, which can skew homeowner experiences.
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.
