Rheem HVAC
Rheem has earned a reputation as one of the most balanced HVAC brands – not only offering premium features but also focusing on practical reliability and wide product availability. For this review, I’m looking at three key products that represent the core of Rheem’s residential lineup: the Prestige® Series R98V Furnace for heating, the Prestige® Series RA19 Air Conditioner for cooling, and the Prestige® Series RP19 Heat Pump for year-round performance. These models represent Rheem’s higher-end offerings but are still accessible to homeowners who want advanced comfort without straying into ultra-luxury pricing. Over the years, I’ve tested multiple Rheem installs, and I’ve also heard consistent feedback from contractors and homeowners alike – their systems are seen as well-rounded, efficient, and dependable. With that said, let’s break down their performance across the eleven critical aspects

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.
