5 Things That Happen When There Is a Refrigerant Leak in Your Commercial Refrigeration System in Sydney CBD

Refrigerant is what makes your commercial refrigeration work. It absorbs heat from inside the unit and releases it outside, keeping everything at the right temperature. When refrigerant leaks out — even a small amount — the whole system is affected.

The signs can start off subtle. But the consequences build up quickly if the leak is not found and fixed.

Here are the five things that happen when your commercial refrigeration has a refrigerant leak.

1. Your System Works Harder and Your Power Bill Goes Up

When there is less refrigerant in the system, the compressor has to run longer to try to maintain the set temperature. Instead of cycling on and off as it normally would, it runs almost continuously.

This uses significantly more electricity. Many Sydney CBD business owners notice their power bill creeping up before they realise there is a refrigeration problem. A refrigerant leak is one of the most common causes of an unexplained increase in energy costs for commercial refrigeration operators.

2. Temperatures Become Unstable or Too Warm

Without the correct amount of refrigerant, your refrigeration unit cannot hold a consistent temperature. You may notice:

Temperatures fluctuating throughout the day
The unit struggling to reach the set temperature at all
Warm spots inside the unit

For Sydney CBD businesses storing meat, dairy, fresh produce, or pharmaceuticals, this is a direct food safety and compliance risk. Even small temperature variations above the safe range can compromise product quality and put you in breach of food safety regulations.

3. Ice Builds Up in the Wrong Places

A refrigerant leak can cause ice to form — particularly on the evaporator coils. This happens because reduced refrigerant flow causes the coil temperature to drop lower than normal, freezing the moisture in the surrounding air.

Ice build-up on the evaporator is not just a sign that something is wrong. It also makes the problem worse by blocking airflow through the coil, which further reduces the unit’s ability to cool properly. Left unattended, it can also damage internal components over time.

4. The Compressor Is Put Under Extra Strain

The compressor is the most important — and most expensive — component in any commercial refrigeration system. When refrigerant is low, the compressor works overtime trying to compensate.

Running continuously under these conditions causes:

Overheating inside the compressor
Accelerated wear on internal components
A significantly higher risk of compressor burnout

A compressor failure is one of the most costly repairs in commercial refrigeration. In many cases, it could have been avoided if the refrigerant leak causing the extra strain had been caught and fixed earlier.

5. Your Stored Stock Is at Risk

This is where the impact of a refrigerant leak becomes most visible and most costly for your business.

When temperatures inside a commercial refrigeration unit become unstable or climb above safe levels, everything stored inside is at risk. Fresh food, frozen goods, dairy, meat, and pharmaceutical products all have strict temperature requirements. When those requirements are not met — even briefly — product can be compromised or unsafe to use.

For Sydney CBD food businesses, stock loss from a refrigerant leak can run into thousands of dollars. And that is before factoring in the potential compliance and liability consequences of serving or selling compromised product.

What to Do If You Suspect a Refrigerant Leak

Do not wait and hope the problem resolves itself. A refrigerant leak does not get better on its own. It gets worse.

Watch for the warning signs

A power bill that has gone up unexpectedly, temperatures that are not stable, ice forming in unusual places, the compressor running constantly, or a hissing sound near the unit are all signs worth acting on promptly.

Do not just top up the gas

Adding refrigerant without finding and fixing the leak is not a repair. The gas will leak out again and the problem will return — usually worse than before.

Call a licensed refrigeration technician

Only a licensed technician can legally handle refrigerant in Australia. The leak needs to be found, repaired, pressure tested, and the system properly recharged.

At BM Refrigeration, we use electronic leak detectors and pressure testing to find the exact source of a leak before carrying out any repair. We fix the cause — not just the symptom.

Frequently Asked Questions — Refrigerant Leaks in Commercial Refrigeration

This depends on the size of the leak. A large leak can cause temperatures to become unsafe within hours. A slow leak may take weeks or months to become obvious — but it causes ongoing damage to the compressor and ongoing cost in wasted electricity throughout that period.

When there is less refrigerant flowing through the evaporator coil, the coil temperature can drop lower than normal. This freezes moisture in the air around the coil, causing ice to form. The ice then blocks airflow through the coil, which makes the cooling problem worse.

The evaporator had multiple leak points. Repairing individual leak points on a heavily used evaporator in a high-demand kitchen is not a long-term solution. A full replacement provides a reliable, warranted component that the kitchen can depend on without the ongoing risk of further leaks developing at other points in the same unit.

It depends on how severe the leak is. If the unit is still holding temperatures within the safe range, it may continue to be used briefly. However, a refrigerant leak will not resolve itself. The longer it continues, the more refrigerant is lost, the harder the system works, and the greater the risk to both your stock and your compressor.

Topping up refrigerant adds gas without addressing why it was lost. The gas will escape again through the same leak and the problem will return. Fixing the leak means finding the exact source, repairing it, confirming the repair under pressure testing, and recharging the system correctly.
