Is your AC unit performing poorly or cutting out? A pressure fault could indicate a more serious underlying problem. Our experts pinpoint and resolve these critical issues.
AC systems rely on precise refrigerant pressure for efficient operation. A pressure fault can manifest as poor cooling/heating, the unit frequently cycling on and off, or complete system shutdown, often accompanied by error codes. These faults typically point to issues like refrigerant leaks, blockages, or compressor problems, all of which require immediate professional attention to prevent further damage.
Our engineers will conduct a comprehensive pressure analysis using specialised gauges and diagnostic equipment. We'll check both high and low-side pressures against manufacturer specifications, identify any abnormal readings, and investigate potential causes such as refrigerant levels, expansion valve issues, or blockages in the system. We'll also examine the pressure switches themselves.
