The system pairs a Dave Lennox Signature SLP99V variable-capacity gas furnace (model SLP99UH135XV60D, up to 99% AFUE) with a Lennox Signature SL22KLV 5-ton variable-capacity heat pump and a CK40 cased coil, all managed by a Lennox S40 smart thermostat with iHarmony zoning, smart room sensors, and an air quality monitor.
