I don't see the actual article content provided. You've given me the title "Lennox International Inc. (Q1 2026 Earnings Call Transcript)" and noted it's from Seeking Alpha, but the article text itself is missing.

To write an accurate summary following your strict guidelines, I need:

- The earnings numbers (revenue, profit, margins) - What management said about performance - Guidance for upcoming quarters - Any specific challenges or wins mentioned - Direct quotes from executives

Please paste the full article content, and I'll deliver a 150-250 word summary with the required CATEGORY and TAGS lines.
