In the world of commercial facility management, the “Efficiency Gap” isn’t the only way to lose money during an HVAC upgrade. The most significant—and often overlooked—financial leak occurs before the new unit is even turned on: the installation of an adapter curb.
When a new rooftop unit (RTU) doesn’t match the footprint of the old one, contractors must install a heavy metal transition frame known as an adapter curb. While it solves a physical problem, it creates a fiscal one. At Allied Commercial, we’ve engineered a better way. Our “fit-all” design philosophy is specifically built to eliminate the need for these costly modifications.
The “Invisible” Expense of Adapters
An adapter curb isn’t just a piece of metal; it’s a catalyst for a chain reaction of expenses:
- Fabrication Costs: Custom adapter curbs can cost thousands of dollars in materials and specialized labor before they even reach your job site.
- Added Weight: Adapters add significant weight to your roof. In many cases, this requires a structural engineer’s assessment to ensure the roof can handle the new, taller load.
- Extended Crane Rentals: Installing an adapter is a two-step process—remove the old unit, set the curb, then set the new unit. This doubles your “pick” time and extends expensive crane rentals.
Protecting Your Roof’s Integrity
Every time you modify a roof curb, you risk the integrity of the roof’s weather seal. Adapter curbs raise the unit’s center of gravity and create new seams that are susceptible to leaks in Florida’s heavy tropical downpours. By utilizing an Allied unit that fits your existing curb, you maintain the original, engineered seal of your building, drastically reducing the risk of water damage and mold.
Static Pressure and Efficiency Loss
Adapter curbs often force the air to make sharp, 90-degree turns to move from the new unit into the old ductwork. This creates “static pressure” resistance.
- The Allied Advantage: Because Allied units are designed to align with the most common industry footprints, the airflow remains laminar and direct. This means your high-efficiency blower motor doesn’t have to work twice as hard to push air through a “choke point,” saving you money on electricity from day one.
Speed to Commissioning: The Orlando-Tampa Advantage
In Central Florida, business doesn’t stop for construction. Whether you are managing a retail center in Kissimmee or an office complex in Tampa, every hour your HVAC system is offline is an hour of lost revenue or tenant dissatisfaction. Because Oldach stocks Allied units with these “universal” footprints in our local hubs, we can facilitate a “drop-in” replacement. What takes other brands three days of curb-work, Allied and Oldach can often accomplish in a single afternoon.
Capital Expenditure (CapEx) Optimization
As a decision-maker, your goal is to put your budget into technology, not tin. When you avoid the cost of an adapter curb, those thousands of dollars are reinvested into the unit itself—allowing you to opt for higher SEER ratings or advanced filtration systems that provide a tangible return on investment.
Design That Respects Your Bottom Line
A “fit-all” footprint is more than a convenience for the contractor; it is a strategic financial benefit for the owner. By choosing Allied Commercial systems through the Oldach network, you are choosing a path that respects your building’s structure and your company’s budget.
Don’t pay for the “middleman” of metal adapters. Choose the system designed to fit your needs and your existing infrastructure.
