The Debut of Lennox’s SL22KLV Heat Pump for Cold Climates
Charlotte Comfort Systems is excited to introduce the Lennox SL22KLV heat pump, a groundbreaking solution designed to deliver exceptional heating and cooling performance even in extreme cold temperatures. With cutting-edge technology and impressive efficiency ratings, the SL22KLV sets a new benchmark for home comfort.
Revolutionary Performance and Energy Efficiency
The Lennox SL22KLV heat pump is engineered to operate efficiently across various climate conditions. It boasts an impressive Seasonal Energy Efficiency Ratio 2 (SEER2) of up to 21, an Energy Efficiency Ratio 2 (EER2) of 13.2, and a Heating Seasonal Performance Factor 2 (HSPF2) of 10.5. These ratings ensure optimized energy use and cost savings for homeowners.
Designed to handle both cooling and heating demands, the SL22KLV offers a cooling capacity ranging from 22,000 Btuh to 56,000 Btuh and a heating capacity between 21,600 Btuh and 60,000 Btuh. The system is available in sizes from 2 tons to 5 tons, allowing for flexible applications based on a home’s specific heating and cooling needs.
Designed for Extreme Cold Weather
One of the SL22KLV’s standout features is its ability to provide reliable heating even in sub-zero temperatures as low as -28.9°C (-20°F). This is made possible through Lennox’s most advanced cold climate technology, which includes a variable-speed compressor with Electronic Refrigerant Injection (ERI). This feature dynamically adjusts energy usage based on outdoor temperatures, increasing heating output efficiently when temperatures drop.
Advanced Technology for Maximum Comfort
Equipped with Precise Comfort® technology, the SL22KLV heat pump makes micro-adjustments to its heating and cooling output, ensuring a perfectly balanced indoor climate while maximizing energy efficiency. Unlike traditional heat pumps, which cycle on and off, this variable-capacity system fine-tunes performance in small increments, maintaining consistent comfort levels with minimal energy waste.
Additionally, the sound-dampening system and precision-balanced, direct-drive fan ensure ultra-quiet operation, rated at just 59 dB, making it one of the quietest heat pumps on the market. The unit’s composite base and removable louver panel contribute to durability and easy maintenance.
Eco-Friendly Refrigerant and Smart Integration
The SL22KLV utilizes R-454B refrigerant, an environmentally friendly alternative designed to reduce greenhouse gas emissions while maintaining high performance. Homeowners can also integrate this heat pump with the Lennox S40 Smart Thermostat, enabling precise temperature control and energy efficiency optimization through intelligent automation.
Recognized as ENERGY STAR® Most Efficient 2025
The SL22KLV has been recognized as one of the Most Efficient Cold Climate Heat Pumps by ENERGY STAR® for 2025, solidifying its position as the highest-efficiency, variable-capacity heat pump available. Homeowners can enjoy the warmth of a gas furnace with the efficiency of a heat pump, ensuring comfort without compromise.
