Aircon Pressure Test

When your aircon fails to produce cold air, this could be a sign that the refrigerant gas is running out. That's when a pressure test is recommended to check the gas levels.
What Does An
Aircon Pressure Test Involve?

The aircon pressure test involves injecting nitrogen gas into the gas pipe, fan coil and condenser unit. This will help to pinpoint the specific location within the system where gas leakage is occurring. Once the problem area has been identified, the necessary repairs can be carried out to rectify the fault. Often, the leak point can be at any of the following locations:
- Pipe joints
- Piping
- Indoor unit
- Outdoor unit
Why You May Need to Conduct
An Aircon Pressure Test
An aircon pressure test is used to check the efficiency of an aircon system and to address potential leaks.
Here are the main reasons for conducting an aircon pressure test.
Detect Gas Leakage
One of the main reasons for conducting a pressure test is to identify if there is any leakage in the refrigerant gas. Refrigerant gas is crucial for the proper functioning of the air conditioning system, and any leakage can lead to a drop in cooling performance.
Optimal Cooling Performance
If there is a refrigerant leak, the aircon won't be able to cool effectively. By identifying and fixing the leak, the system can regain its optimal cooling performance, ensuring a comfortable environment indoors.
Preventing Further Damage
If gas leaks are left unaddressed, they can lead to more significant problems in the air conditioning system. Addressing the issue early through pressure testing can prevent costly repairs in the future.
Energy Efficiency
A properly functioning aircon system is needed to cool your home effectively. Detecting and repairing gas leaks can help reduce energy consumption and lower utility bills.
Are Repairs Needed Following
An Aircon Pressure Test?
Repairs to the aircon system may be needed depending on what is found.
- Minor leakage is found in piping that is accessible: In this scenario, welding work may be performed to seal the leakage. Alternatively, piping may be replaced in the affected area.
- If the leaking point is found in a location that is beyond repair, not accessible, due to wear and tear, is obsolete: In this scenario, new piping works may have to be undertaken or a whole system may have to be overhauled with a new installation done.
- If the leaking point is found at the indoor or outdoor unit: In this case, the equipment may have to be replaced.
Conducting an aircon pressure test is crucial to identify potential issues within the system, such as leaks and refrigerant imbalances. This is also part of maintenance and testing to extend the aircon’s lifespan.
