High efficiency variable capacity cold climate heat pump
The Lennox EL21KLV Elite Series is a high-efficiency, variable-capacity, cold-climate heat pump. Designed for year-round heating and cooling, it is particularly effective in colder climates. It provides both heating and cooling while delivering enhanced energy savings and precise temperature control.
Key Features
- High energy efficiency: With efficiency ratings of up to 20.5 SEER2 and 10.0 HSPF2, this heat pump significantly exceeds federal energy-saving guidelines.
- ENERGY STAR® Certified and may qualify for seasonal local rebates
- Variable-capacity technology: The unit can precisely adjust its heating and cooling output from 35% to 100% capacity. This variable operation eliminates temperature swings, improves dehumidification, and delivers more consistent comfort.
- Cold-climate performance: Engineered for regions with colder winters, the EL21KLV uses advanced technology to deliver efficient heating even in freezing temperatures.
- Enhanced dehumidification: By running for longer periods at lower capacity, the system more effectively removes excess moisture from the air, which improves overall comfort.
- Quiet operation: A sound-dampening system and a precision-balanced, direct-drive fan allow the unit to operate as quietly as 60 dBA, comparable to a microwave.
- Durable construction: A proprietary aluminum alloy Quantum™ Coil and a heavy-gauge, galvanized steel cabinet with a composite base resist corrosion and wear from harsh weather.
Technology and Reliability
- Digital-ready: When paired with a communicating Lennox smart thermostat, such as the S40, the EL21KLV can operate as part of a fully communicating home comfort system. This allows for advanced control and optimized efficiency.
- Environmentally friendly refrigerant: The system uses R-454B refrigerant, which is compliant with 2025 EPA regulations and has a lower global warming potential (GWP) than older refrigerants.
- Easy servicing: The cabinet features easily removable louvered panels, providing quick access for cleaning and service
- Lennox Elite Series® Warranty: Elite series models, including the EL21KLV, come with a 10-year limited warranty on the compressor and a 5-year limited warranty on covered components. A 10-year extended limited warranty on components is available upon product registration.
