Air conditioning pressure fault
If your air conditioning system is frequently shutting down or failing to cool efficiently, a pressure fault could be the critical issue, indicating problems with refrigerant levels or flow.
Air conditioning pressure fault
A pressure fault in your AC system often means it's running inefficiently, short-cycling, or shutting down completely due to safety cut-outs. You might notice warm air from the vents, or simply no cooling at all. These faults usually point to problems with refrigerant quantity or flow, which can be detrimental to the compressor if ignored.
Our engineers will meticulously check both high and low-side refrigerant pressures using specialist gauges. We'll look for signs of leaks, assess the condition of the expansion valve, and ensure there are no blockages in the refrigerant lines. We will also check the pressure switches and sensors for correct operation.
