LII vs MKSI 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) accounted for 67% of sales and commercial HVAC (building climate solutions) accounted for the remaining 33% of sales. To be clear, Lennox's commercial exposure is what its peers refer to as "residential and light commercial," 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 the company's flagship HVAC brand.
