Premier Ductwork Installation & Custom Fabrication in New York City
​
Engineering High-Velocity, Zero-Leakage Air Distribution for NYC’s Residential & Commercial Infrastructure.

How do I choose the right ductwork installation company in NYC? The best NYC ductwork installers must provide SMACNA-compliant fabrication, Local Law 97 efficiency audits, and Manual D load calculations. Dezier Air specializes in precision-engineered galvanized and antimicrobial duct systems that reduce energy waste by 30% and meet the strict NYC 2026 electrification mandates.
Navigating NYC’s New Energy Landscape: Local Law 97 & 154
In 2026, New York City is no longer just "installing AC." With the All-Electric Buildings Act and Local Law 97 in full effect, your ductwork is the most critical link in your HVAC chain. Poorly sized or leaky ducts will cause high-efficiency heat pumps to fail and trigger heavy carbon fines for commercial property owners.
​
At Dezier Air, we don't just hang metal; we engineer airflow. Our systems are designed to handle the static pressure requirements of modern VRF and VAV systems, ensuring your building remains compliant, comfortable, and carbon-efficient.
The Dezier Air Precision Installation Process
​
​
To dominate the NYC market, we follow a rigorous 4-stage protocol that ensures your system lasts for decades, not years.
​
1. Advanced Airflow Modeling
​
We utilize Manual J, S, and D protocols to calculate the exact CFM (Cubic Feet per Minute) required for every room. This eliminates the "hot and cold spots" common in older Manhattan brownstones and high-rises.
​
2. Custom In-House Fabrication
​
Generic ductwork doesn't fit NYC's unique architecture. We operate a dedicated sheet metal shop to fabricate bespoke:
-
Rectangular Offsets: For tight plenum spaces.
-
Transitions: For seamless unit integration.
-
Spiral Ductwork: For aesthetic, exposed industrial designs.
​
3. Class A Leakage Sealing
​
According to the Department of Buildings (DOB), duct leakage is a primary cause of energy failure. We utilize mastic-sealed joints and internal gaskets to achieve a Class A Seal Rating, virtually eliminating air loss before it reaches the vent.
​
4. TAB (Testing, Adjusting, & Balancing)
​
Every Dezier Air installation concludes with a certified TAB report. We measure the velocity at every register to ensure the system is performing exactly as the engineers intended.
Frequently Asked Questions
​
​
What is the cost of ductwork installation in New York City?
​
In NYC, commercial ductwork installation typically ranges from $18 to $35 per linear foot. Factors influencing price include accessibility (high-rise vs. ground floor), the gauge of steel required, and specialized fire-stopping mandates required by the NYC Building Code.
​
How does ductwork affect air quality in NYC?
​
Old, unsealed ducts act as a vacuum for city dust and pollutants. Dezier Air installs non-porous, antimicrobial-lined ducts that prevent mold growth and integrate seamlessly with HEPA and MERV 14+ filtration systems to ensure "Museum-Grade" air in your home or office.
​
Can I replace my ducts without tearing down my walls?
​
In many NYC apartments, we utilize high-velocity mini-duct systems or Aeroseal technology to repair or replace air distribution paths with minimal structural disruption.
