About Lennox
Lennox earned a Department of Energy nod as the first manufacturer to develop a next-generation cold-climate heat pump for northern states. That recognition came from the SL22KLV, which uses Electronic Refrigerant Injection to maintain efficiency when temperatures drop below zero. For a Texas-based company founded in 1895, the pivot toward cold-climate leadership is notable.
Lennox owns several brands including Armstrong Air, AirEase, Concord, and Ducane. The company runs the largest factory-owned distribution network in the industry and maintains 6,000+ dealers through its Premier Dealer Program. That vertical integration gives Lennox more control over pricing and service quality compared to competitors who rely on independent distributors.
For tax credit purposes, all Lennox-owned brands use QMID L7S0. The SL28XCV and SL22KLV heat pumps meet CEE highest tier efficiency requirements, qualifying for the maximum $2,000 federal tax credit under 25C.
UniColorado is Denver's most trusted heat pump installer, helping Front Range homeowners navigate rebates, tax credits, and equipment options for Colorado's challenging climate.
