Commercial HVAC Design & Engineering Services Atlanta, GA

Engineering That Supports the Build

Good mechanical design only matters if it can actually be built, and ours is created by the same firm that installs it. Mallory & Evans' licensed mechanical engineers handle load calculations, system design, energy modeling, BIM coordination, and stamped drawings for commercial and industrial projects. Because engineering and field crews work under one roof, your design translates directly into a buildable, coordinated installation, whether you need full design-build or engineering only.

"We're not making cookies in a hospital, we're saving lives. Without Mallory & Evans, I'd have to trust someone I'm far less comfortable with."

Mechanical Engineering That Sets Up the Build for Success

Mallory & Evans provides commercial HVAC design for projects across Georgia. Our licensed mechanical engineers perform load calculations, system design, energy modeling, and BIM coordination, producing stamped mechanical drawings for permit submission and construction documentation.

Because our engineering team and field crews work under the same roof, our HVAC engineering services translate directly into buildable, coordinated installations. We offer both full design-build delivery and engineering-only services for projects where the owner is using a separate contractor. Commercial HVAC engineering backed by 70 years of field installation experience, that combination is difficult to find. Call our design team today - (404) 297-1007.

FAQs

What Mechanical Design and Engineering Services Do You Offer for Commercial Projects?

We offer load calculations, system selection and design, mechanical engineering, stamped mechanical drawings for permit submission, BIM coordination, design-build delivery, and construction administration. Our commercial HVAC design team in Atlanta, GA serves projects from early feasibility through construction completion.

At What Stage of a Commercial Project Should Mechanical Design and Engineering Begin?

As early as possible, ideally during schematic design or design development. Early engagement allows our engineering team to optimize system design for the building layout, coordinate with structural and architectural teams, and establish accurate budget and schedule estimates before systems are committed.

Do You Provide Stamped Mechanical Drawings and Engineering Documentation for Permit Submissions in Georgia?

Yes. Our licensed mechanical engineers produce and stamp mechanical drawings for permit submission across Georgia. We handle the full permit documentation package and coordinate with local authorities having jurisdiction throughout the review process.

Can Your Engineering Team Optimize Mechanical System Design for Energy Efficiency and Code Compliance?

Yes. Our commercial HVAC engineering team performs energy modeling, load optimization, and system comparisons to identify the most efficient and cost-effective solution for each project. We design to exceed code minimums where the lifecycle economics justify it.

Do You Offer Design-Build Mechanical Services That Combine Engineering and Installation?

Yes. Design-build is one of our core delivery methods. Our HVAC engineering services team produces the mechanical design and then our field crews install it: under one contract, one team, one point of accountability. This approach streamlines the process and reduces the risk of design-construction gaps.

What Types of Commercial Facilities and Systems Does Your Design and Engineering Team Specialize In?

Our team specializes in complex commercial and industrial mechanical systems: hospitals and healthcare facilities, data centers, manufacturing plants, universities, government buildings, aviation facilities, and large commercial developments. We have commercial HVAC system design experience across virtually every facility type in the state.
