HVAC AutoCAD Mechanical Drafting

I have an HVAC project that needs precise, professional mechanical drafting in AutoCAD. The focus is a U-channel card slot frame that forms part of the system’s support assembly. I will provide hand sketches and key dimensions; from there I need clean, fully-notated DWG files ready for fabrication and on-site installation.

Accuracy is critical: every hole, flange and bend on the frame must line up perfectly with the surrounding ductwork and equipment. Dimensioning, tolerances and material call-outs all need to be included so the shop can work straight from the drawing without guesswork.

Please work natively in AutoCAD (any recent version is fine) and export final sheets to PDF as well. A couple of revision rounds to iron out fit-up issues are expected, so keep your source files organised for quick updates. If you have HVAC drafting experience and can turn around high-quality mechanical drawings quickly, I look forward to collaborating with you.
