Why HVAC Systems Are Moving to the Roof — And Why Green Link Leads the Way
Written by Eli Zuelke
The future of HVAC isn’t on the ground; it’s on the roof. Across the country, advances in technology and sustainability concerns are taking contractors to the roof, where efficient, consolidated HVAC units and arrays are the clear choice for modern construction.
The Rise of Rooftop HVAC
Smaller, lighter, and more efficient HVAC units have made rooftop installations not only practical but preferred. According to industry reports, the HVAC rooftop units market is steadily growing at a CAGR (Compound Annual Growth Rate) of 5.7% from 2025 to 2033. (Grand View Research, 2025).
Why more teams are going up top:
- More Usable Space: Free up valuable ground-level real estate for parking, landscaping, or pedestrian areas.
- Reduced Noise: Keep equipment noise away from offices, living spaces, and public walkways.
- Simplified Maintenance: Rooftop units are easier for technicians to access and service without disrupting operations.
- Safety: Rooftop installations reduce the risk of tampering, theft, and accidental damage.
But with these benefits come new challenges, including high winds and temperature swings, as well as snow, ice, and standing water. Supporting rooftop HVAC systems safely and sustainably takes more than just standard materials. It takes engineered innovation. That’s where Green Link steps in.
Why Green Link Is the Smarter Choice
Rooftop HVAC systems are only as reliable as the supports beneath them, and Green Link is redefining what strong, innovative, and sustainable support looks like.
- Engineered Strength: The MetalHead Support System withstands up to 10,000 lbs of compression, outperforming traditional wood or rubber blocks.
- Roof Protection: Wide, stable bases prevent membrane damage and promote proper drainage, reducing pooling, freeze-thaw stress, and ice buildup.
- Fast, Flexible Installation: Lightweight, corrosion-resistant materials with Snap-N-Strut compatibility make setup simple, secure, and adjustable.
- Built to Last: Reusable, recyclable, and backed by up to a 20-year warranty, all proudly made in the USA.
From coastal humidity to northern freeze cycles, Green Link supports are engineered to handle real-world rooftop conditions year after year.
Supporting a Sustainable Future
As energy-efficient design and green construction continue to evolve, rooftop HVAC systems are leading the way toward reducing a building’s footprint and improving building performance. Green Link delivers the strength, reliability, and innovation needed to support this next generation of sustainable rooftop infrastructure.
Because when it comes to rooftop HVAC, your system is only as strong as what’s holding it up.
