Air conditioning pressure test
Need to verify the integrity of your commercial air conditioning system? Our air conditioning pressure testing service ensures leak-free operation for businesses across London, Surrey, Kent, and the M25.
Air conditioning pressure test
If you're installing new AC pipework, suspect a refrigerant leak, or need to confirm a repair, a pressure test is a critical diagnostic step. This test evaluates the system's ability to hold pressure, indicating whether there are any breaches that could lead to refrigerant loss. It's a non-invasive way to identify potential problem areas before a system is put into operation or recharged.
Our engineers conduct a meticulous pressure test by introducing an inert gas, typically oxygen-free nitrogen, into the system at a specific, controlled pressure. They monitor the pressure readings over a set period using calibrated gauges to detect any drops, which would signal a leak. This process allows for precise leak detection without contaminating the system or releasing harmful refrigerants.
