Coleman HVAC

Coleman HVAC main picture

Coleman may be best known for its camping gear, but in HVAC, it’s part of the Johnson Controls family, sharing engineering DNA with York and Luxaire. While smaller in market share than Carrier or Trane, Coleman positions its Echelon® series as a premium residential lineup that combines reliability, efficiency, and installer-friendly design.

For this review, I’m focusing on three flagship models: the CP9C Gas Furnace, the AC21 Air Conditioner, and the HC20 Heat Pump. Together, they demonstrate Coleman’s ability to deliver modern HVAC solutions with modulating, variable-capacity technology that rivals the bigger names. In my field experience, Coleman often appeals to homeowners who want premium comfort at competitive prices, especially in regions where local Johnson Controls dealers are strong.

Armstrong Air HVAC

Armstrong Air HVAC Main Picture

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.
