Full-Scope HVAC Installation for New Construction in Atlanta

Mallory & Evans has been handling commercial HVAC installation in Atlanta, GA for over 70 years. Our team installs rooftop units, air handlers, chillers and cooling towers, heat pumps, boilers, VAV systems, make-up air systems, and specialty systems for commercial buildings of every type, from mid-size office buildings to large hospitals, data centers, and industrial facilities.

We handle the full mechanical scope: load calculations and system selection, equipment procurement, rough-in, ductwork, controls integration, startup, and commissioning. We pull required permits, coordinate inspections, and maintain the licensing required for commercial HVAC work across Georgia.

In-House Fabrication and Heavy Equipment Capabilities

What sets Mallory & Evans apart is the depth of what we bring in-house. Our 45,000+ square foot fabrication shop allows us to prefabricate piping assemblies, ductwork, and equipment supports before they reach the job site, reducing field labor time and improving installation quality. We also operate cranes, rigging equipment, and a full fleet of construction vehicles for heavy equipment placement.

For large commercial projects (manufacturing plants, data centers, or mission-critical facilities), our team has the equipment, the manpower, and the track record to handle industrial HVAC installation work that most contractors can't.

Design-Build HVAC Services

Mallory & Evans also offers design-build HVAC installation services, combining mechanical engineering, equipment selection, and installation under one contract. Our engineers perform load analysis and system modeling to identify the right solution, produce stamped mechanical drawings for permit submission, and execute the installation with the same team.

FAQs

What Types of Commercial HVAC Systems Do You Install?

We install rooftop units, air handlers, chillers and cooling towers, heat pumps, boilers, furnaces, VAV systems, fan coil units, make-up air systems, and specialty systems for commercial and industrial facilities across Atlanta, GA and surrounding areas. We work with all major equipment manufacturers.

How Is the Right HVAC System Selected for a New or Existing Commercial Building?

System selection is driven by building type, occupancy, load calculations, energy goals, local code requirements, and budget. Our design and engineering team performs load analysis and system modeling to identify the right solution before equipment is specified.

What Is the Process for a Commercial HVAC System Installation From Start to Finish?

The process runs from design and load calculations through equipment procurement, rough-in installation, ductwork, controls integration, startup, and commissioning. We coordinate with the GC and other trades throughout, pull required permits, and manage all required inspections.

How Long Does a Commercial HVAC Installation Typically Take?

Duration depends on system complexity, building size, and overall project schedule. A standard commercial HVAC installation for a mid-size office building typically runs several months from rough-in through commissioning. Large or complex installations may run longer. We provide detailed schedules during preconstruction.

Do You Pull Mechanical Permits and Handle Inspections for Commercial HVAC Installations in Georgia?

Yes. We pull all required mechanical permits and coordinate inspections with local jurisdictions across Georgia. Our team is experienced with Georgia's mechanical code requirements and maintains the licensing and insurance required for commercial HVAC installation work.

What Warranties Are Typically Provided on Commercial HVAC System Installations?

Warranty terms vary by equipment manufacturer and project type. Most commercial HVAC equipment carries manufacturer warranties ranging from one to five years on parts, and we provide a workmanship warranty on our installation. Specific warranty terms are established in the project contract.
