TL;DR
Valley Mechanical Services needed a reliable way to protect rooftop refrigerant linesets at Diana Place Apartments in Nyack, New York. With support from MarketAir and Inaba Denko, Slimduct RD provided durable lineset protection, improved piping organization, and helped create a cleaner HVAC installation.
Overview
Diana Place Boutique Apartment Community in Nyack, New York, was designed to provide residents with comfortable and energy-conscious living spaces through modern HVAC technology. The one-and two-bedroom apartments feature Mitsubishi VRF systems that deliver individual temperature control across the property while supporting efficient operation.
The project required a reliable way to protect and manage rooftop refrigerant linesets exposed to outdoor conditions. Inaba Denko worked with Valley Mechanical Services and MarketAir to provide Slimduct RD lineset protection covers, helping create an organized rooftop layout while protecting the HVAC piping from UV exposure, weather, and physical damage.
Customer Profile
Valley Mechanical Services Inc.
Valley Mechanical Services is a mechanical contractor serving residential and commercial projects. For the Diana Place apartment community in Nyack, New York, the team managed the installation of the Mitsubishi VRF system, including the rooftop refrigerant piping layout.
MarketAir Inc.
MarketAir supported the project as the master distributor of Slimduct RD in North America. Their team provided product expertise and project support during the planning process to help develop an effective lineset protection solution for the rooftop installation.
The company reinvented itself in January 2016 as an importer, exporter, manufacturer, and distributor specializing in installation components and accessories for the HVACR industry. It continues to distribute Inaba Denko’s products like LineBrace, RD, PD, and MD, covering both ducted and ductless sectors.
The Challenge
The Diana Place project required Valley Mechanical Services to install individually controlled HVAC systems across 26 apartments and shared spaces. The installation included 27 ductless units with multiple zones per apartment, which required careful planning for refrigerant piping routes. With limited options available, the rooftop was selected as the location for the linesets.
This installation method created a new protection challenge. As James Bencivengo, managing partner at Valley Mechanical Services, stated, “Placing the pipes on the rooftop exposes them to the elements, posing a significant challenge.”
The exposed rooftop piping needed protection from weather conditions, UV exposure, and physical damage. The planned installation of solar panels also required a well-organized piping layout that could support efficient rooftop use. Previous attempts using fiberglass, plastic, and additional insulation did not provide the required level of protection.
Bird activity, including crows damaging the insulation, along with the risk of people stepping on the piping, created concerns about cracks, insulation failure, and long-term system reliability. Valley Mechanical Services needed a durable solution that could protect the refrigerant linesets while maintaining a clean and organized rooftop installation.
The Solution
Facing insulation degradation risks from rooftop exposure and the need for better refrigerant pipe management, Valley Mechanical Services selected Slimduct RD lineset protection covers as the solution for the Diana Place installation.
MarketAir, represented by Gerry Spanger, provided product expertise and project support throughout the planning process. The team reviewed the initial drawings, visited the job site multiple times, and refined the installation approach to match the specific requirements of the rooftop layout.
The final solution used Slimduct RD covers to protect the HVAC piping from environmental exposure, bird activity, and potential damage from foot traffic. The system provided a durable enclosure for the refrigerant linesets while helping Valley Mechanical Services create a cleaner and more organized rooftop installation.
Diana Place, Nyack’s latest boutique apartment community, sets a new standard for sustainable living with its innovative approach to energy efficiency and comfort. With focus on providing residents with optimal temperature control while minimizing environmental impact, Diana Place offers one and two-bedroom apartments equipped with state-of-the-art HVAC systems.

What Was the Strategy Valley Mechanical Used
Valley Mechanical Services installed the refrigerant piping on the rooftop using Slimduct RD covers to create a protected and organized routing system. The team followed the refined installation plan developed with MarketAir and Inaba Denko to position the covers around the rooftop piping layout.
The Slimduct RD system enclosed the insulated linesets and protected them from outdoor exposure, bird activity, and foot traffic. The installation also maintained a cleaner rooftop arrangement while allowing space for other rooftop requirements, including future solar panel installation.
Key Outcomes
The installation of Slimduct RD at Diana Place successfully protected the rooftop HVAC piping while improving overall lineset organization. The covers helped shield the refrigerant piping from environmental exposure, physical wear, and external damage, supporting a cleaner and more reliable installation.
The completed project also improved the appearance and management of the rooftop piping layout. James Bencivengo from Valley Mechanical Services highlighted the result, stating, “I definitely recommend the RD enclosure; the project looked very neat and clean.”
