Installing a VRF heat pump system is a smart way to enjoy more energy savings and efficient temperature control in commercial or multi-unit residential buildings. But here’s the challenge: how do you protect your investment so it lasts for decades?
That’s the question the Phillip Burtner Apartments project near Pittsburgh, Pennsylvania, faced when building its new complex. They needed a solution that could handle exposure to sunlight, weather, and physical wear without reducing efficiency.
The answer came in the form of Slimduct™ RD from Inaba Denko America, which is a durable lineset protection system that adds performance, longevity, and clean design to modern heat pump HVAC systems.
Let’s break it down.
The Challenge: Protecting the VRF Heat Pump System for the Long Run
A VRF heat pump system (Variable Refrigerant Flow) provides flexible heating and cooling by moving refrigerant through multiple indoor units from one or more outdoor units. These systems are common in apartment complexes, schools, and office buildings because they are energy-efficient and easy to control.
Unlike traditional heat pump AC systems, a VRF setup can cool and heat different rooms at the same time. However, this system depends on many linesets and insulation layers that run across walls, attics, or rooftops.
Those refrigerant lines are usually insulated to prevent heat loss and maintain system capacity. But here’s the problem: insulation doesn’t hold up well under UV light or harsh weather conditions. Over time, exposed insulation cracks, fades, or wears down.
Once that happens, the heat pump system loses efficiency and may start consuming more energy to deliver the same comfort. Gradually, your repair costs can add up, especially if the system serves several zones or floors.
So how do you keep those refrigerant lines protected and your heat pump air conditioner system performing like new? You shield them with the right cover solution, which is what Phillip Burtner Apartments did.
The Project: Phillip Burtner Apartments, Pennsylvania
Located near Pittsburgh, the Phillip Burtner Apartments project needed a durable and reliable heat pump HVAC system that could serve multiple units year-round. Comfort Supply Inc. installed a 20-ton VRF heat pump system on the rooftop to provide heating and cooling for 34 indoor units across two buildings.
The architect and the property owner wanted a setup that not only performed well but also looked good. They needed a lineset protection system that would withstand the outdoor environment and maintain a clean design for years.
That’s where Slimduct™ RD came into play.
The Solution: Slimduct™ RD by Inaba Denko America
Slimduct™ RD is a metal lineset cover designed for demanding commercial installations. It’s tough, rust-resistant, and built to handle rooftop, exterior wall, or ceiling applications.
Gerry Spanger from Marketair collaborated with the engineering team to design the system layout, handle material specifications, and oversee the bidding and installation process. Together with Comfort Supply Inc., they selected a Mitsubishi VRF system paired with Slimduct™ RD for maximum protection and performance.
According to Justin Kern from Comfort Supply Inc., “Slimduct™ RD was actually chosen for this project because the majority of the linesets are actually up on the roof, and the architect and the owner wanted to protect the linesets for as long as possible, and we felt that the RD series was going to be the best solution for that.”
Why Slimduct™ RD Works So Well
Slimduct™ RD is engineered for real-world conditions. It’s not just a cover; it’s an armor for your AC heat pump system. Here’s why:
- Corrosion Resistance
The metal construction resists rust even in humid or rainy environments. That means your heat pump HVAC system stays protected no matter the weather. - UV Protection
Sunlight breaks down insulation fast. Slimduct™ RD blocks harmful UV rays, keeping insulation intact and refrigerant lines secure. - Multi-Line Flexibility
VRF systems often use multiple refrigerant lines. The RD series can cover several linesets at once, making it perfect for large commercial installations. - Neat Appearance
It adds a clean, professional finish to any heat pump AC system. Whether installed on walls, ceilings, or rooftops, it looks neat and blends with the building design. - Long-Term Value
By extending the life of the line insulation, Slimduct™ RD helps maintain system efficiency, cutting down on energy waste and servicing costs.
Visual and Functional Value
At the Phillip Burtner Apartments, Slimduct™ RD gave the VRF heat pump system a strong shield against Pittsburgh’s changing weather. Beyond protection, it improved the building’s visual appeal. The rooftop installations stayed organized, giving maintenance teams easier access to service points.
Residents now enjoy steady comfort across all apartments. The system allows precise temperature control and improved airflow throughout both buildings.
The success of this project shows why Slimduct™ RD has become the go-to choice for protecting heat pump air conditioner systems in commercial setups.
How You Can Build a Long-Lasting Heat Pump System
If you’re planning a new heat pump system or upgrading an old one, know that durability starts with protection. Don’t overlook your linesets. Poorly protected refrigeration piping reduces system performance and lifespan.
Whether your project involves a VRF heat pump system for a residential or commercial building, using a proper protective cover like Slimduct™ RD helps you get more efficiency, fewer repairs, and longer service life.
Also, involve your design team and HVAC contractor early in the process. Choosing compatible protection and support components at the planning stage prevents rework later.
Final Takeaway
The Phillip Burtner Apartments project proved that performance and protection go hand in hand. The partnership between Comfort Supply Inc., Marketair, and Inaba Denko America shows what’s possible when you pair advanced technology with smart design. Slimduct™ RD is the finishing touch that keeps your VRF heat pump system efficient, protected, and looking great year after year.

FAQs
What is a VRF heat pump system?
A VRF heat pump system uses variable refrigerant flow technology to heat and cool multiple spaces with one outdoor unit. It adjusts the refrigerant flow based on demand, saving energy and improving comfort.
How does a heat pump HVAC system differ from a traditional AC system?
A heat pump HVAC system can both heat and cool spaces, while a traditional AC system only cools. It transfers heat instead of generating it, making it more energy-efficient year-round.
Why use Slimduct RD for a heat pump air conditioner system?
Slimduct™ RD shields the refrigerant lines and insulation from sun, rain, and impact damage. It extends the lifespan of your heat pump air conditioner system and maintains performance.
Can Slimduct RD be installed on rooftops?
Slimduct™ RD is designed for rooftop, wall, and ceiling installations. Its rust-resistant metal construction makes it ideal for outdoor use in commercial buildings.
TLDR Summary:
A VRF heat pump system offers efficient heating and cooling for large buildings, but only if its refrigerant lines are well protected. The Phillip Burtner Apartments near Pittsburgh used Slimduct™ RD from Inaba Denko America to safeguard their rooftop heat pump HVAC system. The durable, rust-resistant metal cover shields linesets from UV rays and weather damage, extending system life and improving performance. It also boosts the building’s appearance and makes maintenance easier.
