Cooling Coil Leaking? How We Found and Fixed Every Leak on a Custom Cooling Coil in Sydney

A leaking cooling coil is a problem that gets worse the longer it is left. It wastes refrigerant, makes the system work harder, and can lead to a full breakdown if it is not dealt with.

That is exactly what happened on this job. The freezer room was producing snow, and the cause came down to one missing part.

What Was the Problem?

The cooling coil on this system had been leaking refrigerant. A leaking coil means the system keeps losing gas. When that happens, the cooling performance drops and the running costs go up.

Because this was a custom coil, we could not simply replace it with an off-the-shelf part. It needed to be removed, inspected, and repaired properly.

How We Found the Leaks

The first step was to remove the coil from the system completely.

Once it was out, we gave it a full clean and inspection. This is the best way to find every leak, not just the obvious ones. Trying to find and fix leaks while the coil is still in the system means you can easily miss some. Taking it out and inspecting it properly means nothing gets missed.

We found all of the leak points and marked each one before starting any repairs.

How We Fixed It

Once we had found every leak, we repaired each one. We worked through them carefully to make sure every single leak point was sealed.

After all repairs were done, we reinstalled the coil back into the system. We then tested the system fully to make sure it was holding pressure and performing correctly before we left the job.

What Was the Result?

After the repair, the system was back to full performance. The results were clear:

No more refrigerant leaking from the coil
Cooling efficiency was restored
The system was no longer working harder than it needed to
The client had a fully working system again

A proper repair on the coil meant the client did not need to replace the whole system, which saved a significant amount of money.

Why It Is Important to Fix a Leaking Cooling Coil Quickly

A small leak might not seem urgent, but it causes real problems over time. These include:

Refrigerant loss, which means the system cannot cool properly
Higher energy bills as the system works harder to keep up
Extra wear on the compressor and other parts
Risk of a complete system breakdown
Potential food safety issues if the system is used in a cool room or cold storage

The sooner a leak is found and fixed, the less damage it causes and the cheaper it is to repair.

Custom Cooling Coil Repairs in Sydney

Not all cooling coils are standard parts that can be swapped out easily. Some systems use custom coils that need to be repaired rather than replaced. BM Refrigeration has the skills and equipment to find leaks, repair them properly, and get your system running again.

Frequently Asked Questions — Cooling Coil Leaks and Repairs

Common signs include the system not reaching the right temperature, refrigerant needing to be topped up regularly, unusual hissing sounds near the coil, or ice forming in places it should not be. If you notice any of these, it is worth getting the system checked.

In many cases, a leaking coil can be repaired. It depends on how many leaks there are and how bad the damage is. For custom coils that cannot be easily replaced, a repair is often the most practical and cost-effective option.

Removing the coil gives us full access to every part of it. This means we can find all of the leaks, not just the ones that are easy to see. Fixing only some of the leaks and missing others means the problem comes back quickly.

This depends on the size of the coil and how many leaks need to be repaired. Most jobs can be completed in a single visit. We will give you an idea of the time needed once we have assessed the coil.
