Energy Efficient Design
With an efficiency of 16 SEER and up to 9.0 HSPF, the ML14XP1 heat pump keeps your home comfortable and energy efficient.
With years of rigorous testing under the most extreme conditions, our Quantum™ Coil–featuring a proprietary aluminum alloy exclusive to Lennox–is designed to weather the harshest elements.
Dual-Fuel Compatibility
When the ML14XP1 heat pump is installed with a compatible Lennox furnace, it creates a heating system that can switch back and forth between electricity and gas automatically, based on whichever is the most cost-efficient for the weather conditions at the time.
