Engineering for Aging HVAC Systems

Aging HVAC systems — past their design life, running on refrigerants being phased out, or simply no longer performing — need engineering that determines the best replacement strategy, sizes the new equipment correctly, and handles the permit.

What This Engineering Scope Covers

How Apex Grid Handles This

Apex Grid Engineering is licensed in 49 states — every U.S. state except Alaska. Engineering stamping and licensure are confirmed for each project jurisdiction. We engineer property engineering scopes as a standalone service or as part of a coordinated structural, MEP, civil, and geotechnical package.

We work from architectural PDFs, contractor sketches, or existing CAD files and produce stamped engineering documents, permit drawings, and calculations that building departments accept the first time.
