In the world of HVAC and refrigeration, few components are as essential — and often overlooked — as the coil. Whether it’s heating or cooling the air inside a 40-story office tower or maintaining the temperature in a refrigerated case at your local c-store, the coil is doing the heavy lifting.
If you’re managing or maintaining buildings in Ontario — be it a school, transit station, or commercial property — and your system’s coil is on the fritz, you’re in the right place.
This guide covers everything you need to know about Ontario replacement coils — especially those that require precision-matched, made-to-measure solutions. And yes, we’ll show you how KCL helps building operators avoid costly retrofits.
What Are Replacement Coils?
Replacement coils are heat exchangers — either for removing heat (in refrigeration) or transferring it (in HVAC). You’ll find them in air handling units, rooftop systems, chillers, and walk-in freezers.
The two most common types are:
- Evaporator Coils: Found in cooling units and walk-ins, these pull heat from the air.
- Condenser Coils: Located in rooftop and external units, these release heat outdoors.
But not all coils are standard. In large buildings, coils are often custom-engineered to fit a very specific unit and space. Replacing them means you either retrofit the surrounding system — or you match the original specs exactly. KCL makes sure you can do the latter.
Signs You Need a Replacement Coil
Whether you’re managing a busy school campus or a mall HVAC system, catching coil issues early can save thousands in energy and repairs.
Watch for these signs:
- Inconsistent heating or cooling across floors or zones
- Reduced airflow and air quality complaints
- Ice formation or moisture around coil housings
- Unexplained increases in utility costs
- Frequent service calls or system shutdowns
In high-traffic facilities like subway stations and office towers, a failing coil doesn’t just impact comfort — it affects operations, tenant satisfaction, and health standards.
Why Choose Custom Replacement Coils?
Large-scale facilities rarely use off-the-shelf HVAC components. When it’s time to replace a coil, accuracy isn’t optional — it’s critical.
Here’s where KCL shines:
Made-to-Measure, Not Retrofit
Our coils are designed to match exactly what was originally installed. That means no guesswork, no field modifications, and no cutting or welding to make something fit.
Built for Your Building
Whether you’re servicing a Toronto high-rise or a suburban school, we can deliver coils that match the original spec in:
- Size and footprint
- Connection points
- Airflow direction
- Performance characteristics
You get seamless integration — no disruption to your system architecture or ductwork.
Custom Materials and Fin Types
KCL offers various tubing (copper, cupronickel, etc.) and fin configurations, so your replacement is not only identical — it’s optimized for durability and performance.
KCL Systems’ Measuring Services
One of the biggest pain points in coil replacement? Bad measurements.
A misfit coil delays everything — from install to occupancy. That’s why KCL offers on-site professional measuring services, ensuring your coil fits the first time.
We handle:
- Precise field measurements of failed or aged coils
- Drawing validation against original blueprints
- Custom CAD designs ready for fabrication
It’s not just about size — it’s about system integrity. We make sure the replacement coil matches the original thermally and mechanically, every time.
Direct-from-Manufacturer Pricing
Working on a budget? Whether you’re replacing a single chilled water coil or retrofitting multiple units in a public facility, cost matters.
KCL deals directly with coil manufacturers, which means:
- No middleman markup
- Factory-level quality
- Faster lead times
Plus, we’ve spent decades building relationships with some of the best coil fabricators in North America — ensuring you get premium parts at exceptional value.
