Our Packaged Rooftop Unit Replacement Services in Queens
Complete turnkey RTU replacement — engineering, permitting, rigging, installation, and commissioning — for Queens commercial buildings.
Engineering & Equipment Specification
We evaluate your building's load, existing curb, and electrical service to spec a replacement unit that fits without costly structural surprises.
NYC DOB Filing & Permitting
Rooftop equipment replacement typically requires DOB filings. We manage the paperwork so your project doesn't stall on compliance.
Crane & Rigging Coordination
Rooftop access in dense Queens commercial corridors requires careful crane and street-closure coordination — we manage logistics start to finish.
Old Unit Removal & Disposal
Decommissioning and responsible disposal of the old unit is included, so you're not left managing a second contractor for teardown.
Installation & Startup Commissioning
Certified technicians install the new unit to manufacturer spec and complete full startup commissioning before handoff.
High-Efficiency LL97 Upgrade Options
Replacement is the ideal moment to move to a higher-efficiency unit — often the single biggest lever available for reducing a building's LL97 exposure.
