Allied Air Enterprises Inc. is expanding the company’s Z Series heat pump line for the HVAC market.

The company’s commercial division is adding 7.5- to 10-ton heat pumps to the series, which now offers units from 3- to 10 tons for HVAC construction.

“The introduction of new heat pump models to our existing Z-Series provides increased opportunities in the light commercial market,” said Nick Orth, Allied’s commercial division marketing manager. “Not only have we engineered our Z-Series line with compatibility in mind, but we’ve also enhanced the design to make routine maintenance and service easier for contractors.”

Allied is part of HVAC market company Lennox International Inc.
