Heil HVAC
Heil may not be the first HVAC brand homeowners think of, but industry insiders know it as part of ICP (International Comfort Products)—the same corporate family that builds Carrier and Bryant systems. This means Heil equipment often shares the same engineering DNA as its premium siblings, but is marketed at a slightly lower price point with fewer flashy brand campaigns.
For this review, I’ll focus on Heil’s flagship Ion™ series: the Ion 98 G97CMN Furnace, the Ion 21 Variable-Speed Air Conditioner, and the Ion Variable-Speed Heat Pump HVH8. Together, these represent Heil’s top technology tier, blending high efficiency, modulating or inverter-driven performance, and smart connectivity. In my experience, Heil appeals to homeowners who want near-premium comfort without paying Carrier Infinity pricing.
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.
