HVAC Retrofit Project with Custom Sheet Metal

When Standard HVAC Components Just Don’t Cut It

Not every building fits the mold, and neither should its HVAC system. For facility managers across Northern Ontario, off-the-shelf HVAC components can fall short when buildings demand something more precise, more durable, or simply more flexible.

At Bisschops Industries, we specialize in custom HVAC fabrication that meets the exact requirements of your space and system. Whether it’s a retrofit, a new install, or a layout with unique demands, custom components often make the difference between short-term fixes and long-term performance.

Why Off-the-Shelf Components Fall Short

Mass-produced HVAC parts are designed for general use, not your building. While they work for some setups, they can cause real challenges in more complex environments.

Common issues include:

  • Poor fit or airflow due to non-standard layouts
  • Installation delays from hard-to-source or mismatched parts
  • Reduced system performance caused by awkward connections
  • Increased wear due to inefficiencies or design compromises

Over time, these issues can raise operating costs, shorten equipment lifespan, and lead to more frequent service calls.

The Advantages of Custom HVAC Fabrication

Custom fabrication solves these challenges by designing components specifically for your system—not someone else’s. Here’s what you gain:

1. Precision Fit for Better Performance

Custom ductwork and fittings are tailored to your space. That means fewer leaks, smoother airflow, and improved efficiency.

2. Faster Installation with Fewer Modifications

When components are built to spec, your install goes faster, and the result looks and functions better.

3. Long-Term Value

Systems with custom-fitted components tend to perform more consistently over time. That reduces maintenance and improves ROI.

4. Flexibility for Unique Layouts

Older buildings, institutions with tight mechanical rooms, or facilities with mixed-use zones often require components that standard suppliers don’t carry.

Real-World Example: Custom Work That Made the Difference

One school facility in Northern Ontario had recurring airflow issues due to oddly placed beams and duct transitions. Off-the-shelf parts had been forcing airflow through restrictive bends, lowering efficiency.

Our team designed and fabricated a custom elbow and transition box to fit the space perfectly. As a result, airflow improved by 22%, and the HVAC system no longer struggled to reach classrooms at the far end of the building.

Why Facilities Choose Bisschops

We offer more than fabrication, we offer smart solutions built in-house, on time, and to spec. Our Sudbury-based shop produces:

  • Custom ductwork
  • HVAC transitions, plenums, and fittings
  • Ventilation components for specialized environments
  • Structural and sheet metal supports

Because we handle everything locally, we move faster and deliver with greater accuracy, especially when standard options just aren’t good enough.
