Refrigerant Leak Detection: Symptoms, Methods, and Precautions
Entrance
For cooling systems to operate efficiently, refrigerant must circulate in a closed loop. However, over time, microcracks or loosening of connections can lead to refrigerant leaks . This impacts not only system performance but also human health and the environment.
In this article, we explain in detail how you can detect refrigerant leaks, their symptoms, and the precautions you need to take.
1. Signs of a Leaking
🚨 Decrease in Cooling Performance
✔️ If the air conditioner is not cooling enough, the gas may be low.
🚨 Increase in Electricity Consumption
✔️ As gas decreases, the system works harder and consumption increases.
🚨 Frosting and Condensation
✔️ Abnormal ice formation may occur in the pipes or on the evaporator surfaces.
🚨 Abnormal Sounds
✔️ A leakage sound like “sizzle” may be heard in the system.
2. Leak Detection Methods
🔍 1. Foam Test (Soapy Water)
This is the simplest method. Foam is applied to the suspected connection points. If bubbles form, it indicates a leak.
🔍 2. Electronic Gas Leak Detectors
These are devices that detect common gases such as R-134a, R-410A, R-32.
✔️ Fast and precise detection
✔️ Standard equipment of technical services
🔍 3. UV Dye Method
A special dye is added to the system, and leak points become visible by glowing under UV light.
🔍 4. Pressure Test
The system is shut down, nitrogen is injected, and the pressure is monitored. A drop indicates a leak.
3. Why Are Leaks Dangerous?
⚠️ Performance loss : Cooling is not done sufficiently, the system is strained
⚠️ Environmental damage : Fugitive gases mix with the atmosphere and trigger climate change
⚠️ Health risk : Inhaling intense gas can cause dizziness and headaches.
⚠️ Fire risk : Flammable gases (such as R-290) can pose a serious danger if they leak.
4. Leak Prevention and Preventive Maintenance
🔧 Perform regular maintenance: Gas level and connections should be checked
🔧 Use leak detection sensors: This becomes mandatory, especially in large systems
🔧 Have the system installed by a professional: Plumbing errors increase the risk of leaks.
🔧 Use quality equipment and gas: Cheap materials wear out quickly
Conclusion
Refrigerant leaks can silently degrade system efficiency and cause serious long-term damage. Early detection and preventative maintenance are the most effective ways to mitigate these risks.
