Business grew 13 percent during the first half of the 2015 fiscal year at Wolseley PLC, parent company of HVAC construction and plumbing wholesaler Ferguson.

Revenues of existing HVAC market stores in business at least a year increased 11.7 percent. That’s above the 6 percent increase for the same time last year and the 8 percent that ended fiscal 2014.

“Once again, our associates delivered an outstanding performance,” said Ferguson CEO Frank Roach. “Our focus on providing the best possible Ferguson experience to our customers nationwide drove record results.”
