AC Pressure Test
If your air conditioning system isn’t performing as efficiently as it should, a common cause is low refrigerant pressure — often due to a leak. Before any system is commissioned or recharged, FGAS regulations require a full pressure and strength test to ensure the refrigerant gas is not leaking into the atmosphere.
Why Is a Pressure Test Important?
A common misconception is that air conditioning systems “use up” refrigerant gas over time. In fact, these systems recycle the same refrigerant to produce cooling. If your system needs to be topped up regularly, it means there’s a leak — and continuing to operate it in this condition is both inefficient and illegal under FGAS regulations.
Our Aircon Leak and Pressure Testing Process
At Subcooled, we use pressure testing to find leaks before we refill your air conditioning system. This helps prevent refrigerant loss and makes sure the system is safe to use.
The process includes:
- Removing any refrigerant left in the system
- Filling the system with nitrogen to test for leaks
- Using soapy water to find the exact source of the leak
- Sealing and repairing the leak
- Refilling the system with the right amount of refrigerant
- Testing the system to make sure it works safely and well
A full pressure test helps confirm that the system is free from leaks. It can also restore cooling performance, reduce wasted energy and help you meet current rules.
Finding Small Leaks
Even a small leak can affect how well your air conditioning works. It may also lead to refrigerant loss and higher running costs.
We use a pressure gauge to check the pressure inside the system. A drop in pressure can be a sign that gas is escaping. We can then locate the leak and carry out the needed repair.
Once the leak has been fixed, we test the system again. This helps make sure it holds pressure and works as it should.
