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.

EL21KLV Cold Climate Heat Pump
July 11, 2026I recently had to replace a failing heat pump and chose the EL21KLV. This unit is performing great, although I have only used it for cooling to this point. I can see a significant difference already in the electricity use compared to my old unit. This unit runs very quietly.
Yes, I recommend this product.
