Behind every rooftop unit replacement is a custom solution that makes the installation possible 🔨🇺🇸🔥🌵

This commercial curb adapter was fabricated to bridge the gap between an existing roof curb and a new rooftop unit with different dimensions and airflow openings. Instead of modifying the roof structure, a custom adapter allows the new equipment to integrate seamlessly with the existing system.

At Curbs & Ducts AZ, we take field measurements, equipment specifications, and supply/return locations and turn them into a precision-built transition designed for proper airflow, energy efficiency, and a clean installation.🇺🇸🔥

A well-built curb adapter isn't just sheet metal—it's the connection between old infrastructure and new performance.

Custom commercial curb adapter ready for installation 🔨🔥🌵

When a new rooftop unit doesn't match the existing roof curb, a custom curb adapter allows the new equipment to connect properly without disturbing the existing roof system. Using precise field measurements and equipment specifications, we fabricate adapters that maintain proper airflow, maximize system performance, and save contractors time and money.

Built to fit. Engineered to perform.

🔥Finished and ready to go🔥

This custom curb adapter was built to transition an older commercial cabinet to a new residential unit. One side was capped, all seams were fully welded, sealed against air leakage, insulated for efficiency, and painted for a professional finish.

Custom solutions for unique HVAC retrofit projects.

Custom curb adapter in progress 🔨🔥🌵

We're transitioning an older rooftop unit to a new 5-ton system with a fully custom 20-gauge adapter. Welded, sealed, and insulated for durability, efficiency, and a perfect fit in the field.

From residential changeouts to commercial projects, we build custom HVAC solutions that keep installations moving.

Here I'm programming a custom twist elbow. The customer needed this side to stay flat because there's an obstruction in the field, so we're rotating and shifting the fitting to the opposite side while keeping everything aligned correctly.

The software lets us see exactly what the finished fitting will look like before fabrication starts, including the dimensions, pitch, rotation, and centerline geometry. Taking the time to engineer it correctly upfront helps ensure a precise fit and saves time during installation.

Every project is different, and that's where custom fabrication makes the difference.
