SL22KLV - LENNOX HEAT PUMP - The Most Precise and Efficient Heat Pump You Can Buy

Lennox Heat Pump Model No SL25XPV

Upgrade to the SL22KLV Efficient Heat Pump, designed for cold climates with high SEER ratings, precise temperature control, and full compatibility with 2025-compliant refrigerants.

The most precise and efficient heat pump available, featuring Lennox’ most advanced cold climate technology.*

The Dave Lennox Signature® Collection SL22KLV is a heat pump like no other. Utilizing Lennox’ most advanced cold climate heat pump technology, it optimizes efficiency while delivering rich, warm comfort in temperatures as low as -20°F. From its innovative cabinet design that increases durability, to its digital communication features that maximize accurate control, no other heat pump delivers this level of efficiency and precision.*

Leading heat pump technology for the coldest conditions

Our leading heat pump is engineered with Lennox’ most advanced cold climate technology, using a variable-speed compressor with Electronic Refrigerant Injection (ERI) to adjust the energy usage based on the outside temperature. In colder temperatures, the ERI increases heating output efficiently, providing the warm, rich comfort of a gas furnace with the efficiency of a heat pump.

The perfect amount of quiet

To reduce operating sound levels, the SL22KLV uses a sound-dampening system with a precision-balanced, direct-drive fan to ensure smooth, quiet operation. This lets it operate at a volume as quiet as 58 dB, or the sound of a microwave.

Digitally intelligent for accuracy and efficiency

This truly digital product is designed to pair with the Lennox S40 Smart Thermostat as part of a fully communicating home comfort system. Sensors in the equipment allow the thermostat to diagnose issues and automatically make system adjustments to more accurately and efficiently maintain temperature, humidity and air quality.

Cabinets designed for reliability and serviceability

Our most innovative cabinet design features panels that fit securely to the unit to prevent excess noise, along with an easily removable louver panel that allows for quick access by your technician. This proprietary design makes Lennox units more attractive and durable, quieter and easier to install and service, so nothing stands between you and having perfect air in your home.

A refrigerant that’s better for the environment.

This product is compliant with 2025 EPA regulations for lower global warming potential (GWP) refrigerants. The Lennox choice of 2025 Compliant Refrigerant has a lower GWP than its predecessor and is formulated to provide excellent, reliable performance of your system for years to come.
