Lennox

Lennox makes heating, air conditioning, refrigeration and water heating equipment, mostly for North America. It has two segments. Home Comfort Solutions sells furnaces, air conditioners, heat pumps, thermostats, parts and supplies for homes, both directly to contractors through its own stores and through independent distributors. Building Climate Solutions sells rooftop units and other equipment for commercial buildings, refrigeration equipment for food stores and cold storage, and installation and service.

Most home sales replace old systems that break, but new home construction is also a market. In Q2 2026, Home Comfort Solutions had $936 million of revenue and Building Climate Solutions had $610 million. Lennox also buys smaller companies, such as Duro Dyne and Supco in 2025 and Heat Controller in 2026, to sell more parts and products to distributors.

The market prices Lennox for a long fall in home HVAC sales. Home Comfort Solutions revenue fell 21% in Q4 2025, 10% in Q1 2026 and 7% in Q2 2026, because new home construction is weak and distributors bought less. Lower volumes cut segment margin by 130 basis points in Q2 2026, and Lennox lowered its 2026 EPS guidance to $23.00 to $24.00 from $23.50 to $25.00. Investors fear that home demand stays low while inflation and tariffs raise costs, and that the commercial growth cannot offset it.

For the gap to close, home sales must stop falling and return to growth through 2027. Building Climate Solutions must keep its organic growth, which was 15% in Q2 2026, and its margin near 25%. Lennox must also meet its 2026 guidance of about 8% revenue growth and $750 million to $850 million of free cash flow while it integrates Heat Controller. The Q3 2026 report on October 28, 2026, shows the summer season, and the Q4 report with the 2027 guidance in about late January 2027 shows whether home demand recovers.

If home sales stabilize, the gap can close over the next four to six quarters. If housing stays weak through 2027, it can stay open longer.
