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.
Request Engineering SupportApex Grid Engineering is a multi-discipline firm with multi-state PE coverage confirmed per project — we engineer property engineering scopes as a standalone service or as part of a coordinated structural, MEP, civil, and geotechnical package. Our engineers have direct experience with this type of work across commercial, industrial, multifamily, government, and military projects.
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.
Send us a brief description of your project or attach your drawings. We'll review the scope and respond with a proposal within one business day.
