Features
Class-leading heat pump technology
Our advanced cold climate technology delivers a greater amount of heat compared to traditional heat pumps, resulting in a feeling similar to the rich, warm comfort of a gas furnace—even during the coldest outdoor temperatures.
A peacefully quiet environment
To reduce operating sound levels, the EL21KLV uses a sound-dampening system with a precision-balanced, proprietary direct-drive fan to ensure smooth, quiet operation. This lets it operate at a volume as quiet as 55 dB, or the sound of a microwave.
Your Digital Bridge into a World of Perfect Air
The compact, efficient EL21KLV variable-speed heat pump is your digital bridge into a world of perfect air. When paired with a fully digital furnace or air handler and a Lennox S40 Smart Thermostat, it can step into a fully communicating home comfort system, maximizing its 21.00 SEER2 efficiency with modern communication features.

So far, so good
September 15, 2026Six weeks in, and the unit seems to cool and dry the air much more efficiently and quietly than my 20 year old Bryant AC. January will be the real test--whether i can efficiently heat without punting over to my back up gas furnace.
Yes, I recommend this product.
