HVAC products manufacturer Ruskin is raising prices on several of its product lines.

The company said it is increasing prices 3.5 percent on aluminum products for its Swartwout, sound control, and air and sound control products. It is also raising prices 4 percent on all other Swartwout, and air and sound control products. Ruskin is also raising prices for its sound control line 5 percent.

The company blamed the hikes on rising medical and unemployment insurance expenses, along with freight costs and raw materials prices.
