Trane HVAC
Founded in 1885, Trane has long been recognized as one of the most durable and performance-driven names in the HVAC industry. With a reputation built on rigorous testing and engineering, Trane systems are often the choice for homeowners in regions where extreme heat, humidity, or cold put HVAC equipment to the test. Over the years, I’ve installed and serviced countless Trane systems, and I’ve consistently seen them hold up where lesser brands begin to struggle.
For this review, I’ve chosen three residential ducted products that best represent Trane’s current engineering leadership:
- Trane S9V2-VS Gas Furnace – a high-efficiency, variable-speed furnace for steady, even heat.
- Trane XV20i TruComfort™ Variable-Speed Air Conditioner – the brand’s flagship central AC with exceptional humidity control.
- Trane XV20i Variable-Speed Heat Pump – an all-season comfort solution with strong performance in both cooling and moderate heating.
These models reflect the top end of Trane’s offerings in each category and have been selected based on real-world performance data, field testing, and customer satisfaction feedback.
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.
