Wesco’s latest quarter shows how much the AI infrastructure boom is changing the contractor supply chain.
The company reported record second-quarter net sales of $6.7 billion, up 13% year over year. Most importantly for contractors watching the data center market, Wesco said its data center sales reached $1.5 billion, up about 45% year over year. The company also reported record total company backlog, up roughly 60% year over year, and raised its 2026 outlook.
For HVAC and mechanical contractors, this is not only an electrical distribution story.
Data centers need cooling, power, controls, cabling, switchgear, generators, pumps, water systems, and mechanical infrastructure. When a supply-chain giant like Wesco is reporting $1.5 billion in quarterly data center sales, it shows that AI infrastructure is creating demand far beyond servers and chips.
This matters for contractors because the data center buildout affects labour availability, equipment lead times, project scheduling, and competition for technical talent. Electrical infrastructure may be the first headline, but cooling and thermal management are inseparable from power growth.
If data center sales continue to rise at this pace, HVAC contractors should expect more competition for chillers, controls talent, commissioning specialists, sheet metal labour, hydronic expertise, and project managers who can handle mission-critical work.
Contractor Takeaway
Wesco’s $1.5 billion data center sales quarter is a warning and an opportunity.
Contractors near data center markets should prepare for more mission-critical work, but also for tighter labour, longer lead times, and more complex coordination between electrical, mechanical, and controls teams.
AI may be digital, but the supply-chain demand is very physical.
