Retrofit vs. Replace: Making the Right Call for Aging HVAC Systems

As commercial and industrial HVAC systems age, performance naturally begins to decline. When that happens, many facility teams assume a full unit replacement is the only option. But in many cases, it isn’t necessary — and it certainly isn’t the most cost-effective solution.

At Re-Coil Solutions, our name says it all: Why replace the entire unit when you can just re-coil?

What Is Retrofitting?

Retrofitting means replacing the coil components inside your HVAC system while leaving the main unit, ductwork, and infrastructure intact. It’s a strategic way to restore lost performance, extend equipment life, and avoid the high costs and disruptions that come with a complete replacement.

We custom-engineer coils to match your exact specifications, allowing for a seamless fit and optimal performance — even in older or discontinued systems.

When Retrofitting Makes Sense for HVAC Systems

In most cases, the system's structure is still in good condition. It’s the coils that have suffered from corrosion, reduced airflow, or loss of capacity. Retrofitting focuses on that core issue — and solves it without replacing what still works.

Here are a few key benefits of retrofitting:

• Significantly lower cost compared to full replacement

• Minimal system downtime and reduced disruption to operations

• Added lifespan of 5 to 10 years or more

• Improved system efficiency and heat transfer

• No need for redesigns, permits, or major construction

• Custom fabrication for legacy and hard-to-source OEM models

If the unit housing is still sound, retrofitting is often the smarter path forward.

When Full Replacement May Be Necessary

While retrofit solutions work in most situations, there are exceptions. A full system replacement might be required if:

• The unit has severe structural damage or corrosion

• Multiple internal components beyond the coil have failed

• The system can no longer meet the building’s capacity requirements

Even in these cases, a retrofit can serve as a temporary fix to keep the system operational while long-term plans are made.

Why Choose Re-Coil Solutions

At Re-Coil Solutions, we focus exclusively on custom coil replacement. We don’t sell complete units — we specialize in helping our customers extend the life of the ones they already have.

Our team provides:

• Custom coil design and fabrication

• Free onsite measurement to ensure a perfect fit

• Durable material options, including copper, stainless steel, and coated coils for corrosive environments

• Solutions for both standard and legacy systems

Whether you’re dealing with a leaking condenser coil, a clogged hot water coil, or a failing steam system, our goal is simple: restore your system’s performance and keep your operations running.

The Bottom Line

Not every aging HVAC system needs to be replaced. If your equipment is structurally sound, replacing the coils is often all it takes to restore performance and reliability.
