Are chronic equipment breakdowns, surging utility bills, and uncomfortable indoor temperatures impacting your business operations? In New York City's demanding climate, your commercial property's mechanical infrastructure requires absolute precision. A professional packaged rooftop unit installation dictates whether your building secures 15 to 20 years of reliable performance or faces a decade of code violations and constant emergency repairs.
American HVAC Corp (DOB License #: GC-622134) is your trusted, fully licensed mechanical contractor serving Manhattan, Brooklyn, Queens, The Bronx, and Staten Island. We manage every phase of your installation in-house—from precise load calculations and custom structural curbs to multi-block crane logistics, Department of Buildings (DOB) approvals, and final sign-offs.
If your commercial RTU is over 15 years old, it is likely draining your operating budget through frequent compressor failures, refrigerant leaks, and plummeting energy efficiency. Our specialized packaged rooftop unit replacement service transforms an aging liability into a high-performance asset designed for maximum output and compliance.
An undersized system runs constantly and fails to cool properly, while an oversized unit short-cycles and wastes massive amounts of energy. Our end-to-end replacement services cover everything your facility requires:
Whether developing a new commercial structure or expanding an existing facility, our engineering team delivers turnkey execution designed to maximize energy efficiency and structural integrity.

In New York City, a complete commercial packaged rooftop unit (RTU) installation or replacement typically ranges from $8,000 to $45,000+, depending heavily on the tonnage, equipment tier, and structural requirements. Smaller 3-to-5 ton units for retail storefronts or small offices run $8,000 to $14,000, while mid-size 6-to-10 ton systems range from $14,000 to $22,000. Large industrial 12.5-to-25+ ton setups range from $22,000 to $45,000+. Total project pricing in NYC also accounts for localized complexities, including crane rigging, street permits, traffic safety plans, and custom structural adapter curbs.
Yes. The NYC Department of Buildings mandates mechanical and structural permits for all commercial rooftop equipment, and gas-fired units require dedicated FDNY sign-offs. Operating under DOB License #: GC-622134, we handle all municipal paperwork, permits, and final inspections for you.
Most single-unit commercial installations take 1 to 3 days, depending heavily on crane scheduling, electrical tie-ins, and municipal inspection availability. Multi-unit projects are custom-scoped during your initial site survey.
If your new packaged unit precisely matches the old unit's footprint and utility connection points, the existing curb can often be reused. If dimensions differ, we fabricate and install a structural adapter curb to exact specifications.
We work with all leading manufacturers, including Carrier, Daikin, Trane, YORK, Lennox, AAON, and more, ensuring you get the ideal system for your building's specific demands.
NYC Local Law 97 places strict limits on carbon emissions for commercial buildings over 25,000 square feet, with heavy financial penalties for non-compliance. Upgrading to high-efficiency heat pump RTUs or high-SEER modular equipment during a replacement significantly reduces your building's carbon output, protects you from municipal fines, and cuts long-term energy consumption.
Stop losing money to inefficient equipment and frequent breakdowns. Secure your building's comfort and compliance today.
