LII vs NDSN Comparison

Lennox International manufacturers and distributes heating, ventilating, air conditioning, and refrigeration products for the North American replacement (75% of sales) and new construction (25% of sales) markets. Residential HVAC (home comfort solutions) accounts for 67% of sales and commercial HVAC (building climate solutions) accounts for the remaining 33% of sales. Lennox's commercial exposure is what its peers refer to as residential and light commercial, and lacks the scale and complexity of what is referred to as an applied solution. The company goes to market with multiple brands, but Lennox is its flagship HVAC brand.

Nordson manufactures equipment (including pumps, valves, dispensers, applicators, filters, and pelletizers) used for dispensing adhesives, coatings, sealants, and other materials. The firm serves a diverse range of end markets including packaging, medical, electronics, and industrial. Nordson's business is organized into three segments: industrial precision solutions, medical and fluid solutions, and advanced technology solutions. The company generated approximately $2.8 billion in revenue in its fiscal 2025.
