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 & Pressure Testing Process
At Subcooled, we carry out professional pressure testing to identify and fix leaks before recharging your system.
The process includes:
-
Recovering any existing refrigerant gas from the system
-
Pressurising the system with nitrogen to test its integrity
-
Locating leaks using soapy water (a reliable and safe method)
-
Sealing the leak once identified
-
Recharging the system with the correct amount of refrigerant
-
Recommissioning the system to ensure it runs safely and efficiently
By ensuring your system is leak-free and fully pressurised, you not only comply with regulations but also restore full cooling performance and energy efficiency.
Identifying Small Leaks with Precision
Small leaks in your air conditioning system can significantly impact its efficiency and compliance with regulations. By using a pressure gauge, we can measure and monitor the system’s internal pressure levels accurately. Any unexpected pressure drops often indicate the presence of small leaks. Once detected, these leaks are promptly addressed to ensure your system operates at peak efficiency without any refrigerant loss.
