Carrier Global is a Palm Beach Gardens, Florida-based climate-control and refrigeration operator that runs the Carrier, Otis (separated), and broader portfolio of HVAC, refrigeration, and fire-security brands, and the company is in the middle of a fiscal second quarter that demonstrates the kind of margin-expansion profile the climate-control operator cohort has been waiting for. Q2 2026 total net sales of $6,351 million were 3.9 percent above the prior-year quarter's $6,113 million, the H1 2026 net sales of $11,692 million were 3.2 percent above the prior-year period's $11,331 million, and the operating-income profile produced the kind of margin expansion the company has been positioning for. The combination of the revenue growth and the operating-income profile is the cleanest single-sentence read on what the climate-control operator business model is producing.
