Lennox International Inc. introduced the Dave Lennox Signature SLP99VK gas furnace on January 8 2026, offering a 99 % seasonal energy‑efficiency rating that matches the company’s high‑performance product line. The furnace incorporates a built‑in Refrigerant Detection System (RDS) that eliminates the need for a separate installation kit, reducing dealer labor and material costs while enhancing safety for low‑GWP refrigerants.
The SLP99VK is dual‑fuel compatible, automatically switching between natural gas and electric heat‑pump modes to optimize comfort and efficiency across seasonal temperature swings. It also integrates with Lennox’s S40 Smart Thermostat and PureAir filtration system, providing homeowners with advanced control, remote monitoring, and improved indoor air quality. These features position the furnace as a premium offering in the residential HVAC market, where demand for high‑efficiency, smart‑home‑ready products is accelerating.
Lennox’s product launch comes at a time when the company is advancing its R‑454B refrigerant transition. The integrated RDS is particularly valuable as the industry moves toward lower‑global‑warming‑potential refrigerants, where leak detection is critical for safety and regulatory compliance. By simplifying installation and reducing dealer costs, the SLP99VK strengthens Lennox’s direct‑to‑contractor distribution model and supports dealer confidence during the transition.
Financially, Lennox reported strong results in the most recent quarter, with revenue of $1.3 billion and adjusted diluted EPS of $5.60, a 22 % core‑revenue increase and a 54 % year‑over‑year EPS gain. The Home Comfort Solutions segment grew 25 % in revenue, underscoring robust demand for Lennox’s high‑efficiency products. Management highlighted disciplined cost control and a favorable mix shift toward premium, high‑margin offerings as key drivers of the earnings beat.
Looking ahead, Lennox maintained its full‑year 2025 guidance of core revenue growth of approximately 2 % and adjusted EPS between $22.00 and $23.50, reflecting confidence in continued demand for its advanced HVAC solutions. The SLP99VK launch is expected to contribute to this outlook by expanding Lennox’s high‑efficiency product portfolio and reinforcing its competitive advantage in a market that increasingly values energy savings, smart integration, and refrigerant safety.
The launch also aligns with Lennox’s broader strategy to capture market share in the premium residential HVAC segment, where the company’s operating margin has consistently exceeded 19 %. By delivering a product that meets evolving regulatory standards and consumer expectations, Lennox positions itself to sustain growth and profitability in a highly competitive environment.
