What AES Industries does

AES Industries, Inc. is a privately held U.S. manufacturer founded in 1988 and headquartered in Tallassee, Alabama, that specializes in custom-engineered HVAC accessories for commercial buildings. Its core product portfolio comprises adapter curbs (sizes from 1 to 130 tons, designed to transition between existing roof curbs and new HVAC equipment without penetrating the roof membrane), drop box diffusers for high-capacity long-throw air distribution, wind and seismic brackets built from heavy 10-gauge steel rated to withstand 150 mph wind loads, and structural roof curbs fabricated from heavy-gauge galvanized steel with full-height internal dividers and P.E. stamps available in all 50 states. The company operates four fabrication facilities across the country — Tallassee AL, Reno NV, Weatherford TX, and Wheeling WV — to minimize freight costs and lead times for national account programs.

The business model centers on direct enterprise sales to multi-facility commercial customers, positioning itself as a single-source supplier for national account HVAC replacement programs. AES serves large national retail, grocery, pharmacy, and quick-service restaurant chains — including Walmart, McDonald's, Target, Kroger, Lowe's, Walgreens, Dollar General, Petco, Ulta Beauty, Simon, Big Lots, and Shopko — through custom one-time-sale manufactured products priced on a quote basis. Revenue is generated through three streams: roof curb product sales, the AES Mechanical service division managing multi-facility HVAC unit replacement programs, and the AES Recycle subsidiary providing eco-friendly equipment recycling and asset recovery. The company maintains a strategic linkage with Lennox International, evidenced by Lennox-hosted careers infrastructure, co-branded footer, and shared legal/policy references, suggesting a parent, distribution, or close OEM partnership arrangement. Pricing is not publicly disclosed.

• Nailor Industries: Manufacturer of commercial HVAC diffusers, grilles, dampers, and air-handling components. Direct overlap with AES's diffuser and ventilation component offerings for the same contractor customer base.
• Hart & Cooley (including Milcor): Produces HVAC grilles, registers, diffusers, and roof curbs under the Milcor brand. Most directly comparable competitor to AES's combined roof curb plus diffuser portfolio.
• Loren Cook Company: Major U.S. manufacturer of commercial and industrial fans, blowers, and air-handling equipment. Comparable in scale and product overlap with AES's drop box diffuser and air distribution offerings.
• CaptiveAire: National manufacturer of commercial kitchen ventilation systems, including rooftop units and supporting curbs/ductwork. Comparable in serving multi-facility commercial customers with fabricated HVAC solutions.
• Metal-Fab: Manufactures venting and ducting products for HVAC and chimney applications. Adjacent to AES's duct and air distribution components for commercial HVAC installations.
• KCC (Kool Curbs / Roof Curb Systems): Specialty manufacturer of adapter curbs and roof curbs for HVAC replacement projects. Closest head-to-head competitor in the adapter curb retrofit niche that defines AES's core product.

Broad incumbents

• Greenheck Group: One of the largest U.S. manufacturers of commercial ventilation equipment, including fans, dampers, louvers, and air-handling systems. A broad incumbent that overlaps with AES but operates at much larger scale across many more HVAC categories.
• Titus (Johnson Controls): Tier-one commercial air distribution brand within Johnson Controls, offering diffusers, terminal units, and air-handling products. Comparable diffuser portfolio but part of a much broader building controls/HVAC portfolio.
• Ruskin (by Johnson Controls): Established manufacturer of commercial HVAC louvers, dampers, and air control products. Larger incumbent with comparable commercial air distribution overlap to AES's diffuser business.
