Product Overview

Merit® Series | ML14KP1 Heat Pump 

Standard-efficiency, single-stage heat pump compatible with 2025 Compliant Refrigerant 

Energy Efficiency & Performance 

  • Efficiency rating meets or exceeds energy efficiencies of 14.30 SEER2 and 7.50 HSPF2. 
  • ENERGY STAR® Certified – meets or exceeds federal guidelines for energy-efficient performance. 
  • Federal Tax Credit Eligible – this product is eligible for the Energy Efficient Home Improvement Credit (Internal Revenue Code Section 25C). 
  • High-efficiency outdoor coil – provides exceptional heat transfer and low air resistance for high-efficiency operation. 
  • Single-Stage Compressor – a single-stage unit is either on or off, working at full capacity when in use. 

Quiet Operation 

  • Sound levels – as low as 74 dBs. 
  • Direct-drive fan – precision-balanced direct-drive outdoor fan is designed to provide quieter operation and longer product life. 

Craftsmanship & Reliability 

  • Quantum™ Coil – 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. 
  • Cabinet Construction – heavy-gauge, galvanized steel construction, louver coil guard, baked-on powder finish and durable zinc-coated steel base provide long-lasting protection against rust and corrosion. 
  • Braze-free installation flexibility – our 2025 compliant systems can accommodate braze-free fittings, giving you greater flexibility when installing. 
  • Drainage holes – prevent damaging moisture from collecting inside the base pan. 

Safety & Sustainability 

  • This product uses R-454B refrigerant which meets the 2025 EPA regulations for lower global warming potential (GWP) refrigerants. 
  • Our 2025 compliant systems feature a Refrigerant Detection System (RDS) mandated by the new safety code created for A2L, or mildly flammable refrigerants. The RDS is required for systems with over four pounds of refrigerant and consists of two components: the sensor, which detects leaks, and the control board, which interrupts unit operation and activates the indoor blower to disperse leaks, ensuring safe operation.
