Commercial Horizontal Package Units

Not every commercial building wants its cooling equipment on the roof. A horizontal package unit sits on a ground-level pad beside the structure and discharges conditioned air sideways into ductwork entering through the wall, which keeps technicians off ladders, simplifies inspections, and avoids the structural questions a rooftop install raises. For single-story retail, service shops, and small offices, that accessibility is often the deciding factor.

You might be replacing an existing side-discharge unit and matching the duct connections your building already has, or specifying new equipment where roof access is impractical. Either way, the decision comes down to capacity and electrical service, and our team will confirm both against your building before the unit ships. Every system here arrives as one complete cabinet, so installation stays predictable and future service stays simple.
