How Valley Mechanical Services Used Slimduct RD Casing for AC Pipes to Ensure Long-Term Durability and Clean Installations
In the heart of Nyack, New York, a once-abandoned bowling alley has been transformed into a luxurious condominium complex. The HVAC portion of the project was led by James Bencivengo, owner of Valley Mechanical Services in Rockland County. It presented a series of unique challenges — from sustainability requirements to rooftop environmental exposure.
The Challenge: Sustainability Meets Practicality
As New York state regulations no longer permit major gas utilities in mixed-use buildings, the team had to rethink traditional HVAC solutions. The answer? Cold weather heat pumps — ideal for the 26 residential units — but they came with logistical hurdles.
With solar panels added to meet sustainability goals, outdoor condensing units had to be placed strategically across the rooftop. That meant running AC pipes through multi-story shaft ways, making durability and protection of those lines an absolute priority.
The Solution: Slimduct RD Rooftop Casing for AC Pipes
Bencivengo and his team turned to a trusted solution: Slimduct RD. Designed for commercial rooftop applications, RD provided exactly what this project needed — a rigid, weather-resistant cover that protects refrigerant lines from:
- UV deterioration
- Foot traffic (from solar inspections, roof maintenance, and firefighter access)
- Heavy snow loads
- Extreme summer heat
Having used RD in past projects, Valley Mechanical felt confident in its strength, durability, and professional appearance. It allowed for seamless line set management, even in the complex, vertically stacked layout of the building.
The Result: Durable, Professional, and Long-Lasting
All materials were supplied by Marketair, and the installation was completed in just a few weeks. The final rooftop layout not only met engineering and safety codes but also delivered a visually clean, polished finish that aligned with the luxury standards of the new condos.
Bencivengo summarized their experience:
“We keep coming back to RD for three reasons: rigidity, durability, and appearance. It gives us the confidence that our work will stand up to the elements — and still look great years down the road.”
Product Highlight: Slimduct RD
Engineered specifically for rooftop environments, Slimduct RD is a commercial grade lineset cover system that ensures long-lasting protection from UV rays, impact, and extreme temperatures. Ideal for solar-integrated or heat pump applications where rooftop access is routine.
