Diagnosing Poor AC Cooling in Desford
ACRC LTD was recently called out to a site in Desford, Leicestershire, where a customer's wall-mounted air conditioning unit was failing to cool properly. The air-off temperature was exceptionally poor, immediately pointing to the classic signs of a refrigerant leak.
Nitrogen Pressure Testing & Fault Finding
Our engineers connected refrigerant gauges to check the suction pressures, confirming the unit was running dangerously short at just 20psi. Following strict F-Gas regulations, we safely reclaimed all remaining refrigerant into a dedicated reclaim cylinder.
To pinpoint the exact location of the fault, we pressurized the system with oxygen-free nitrogen. Once the system was at high pressure, we thoroughly checked the flare joints and all standard leak-prone areas. Both the indoor evaporator and outdoor condenser were completely stripped down, and the pipework was tested with a specialist leak-detecting spray.
Identifying Micro-Leaks in the Coil While checking the condenser, we found multiple small coil leaks (as seen in the attached photo). When micro-leaks occur in a coil, there is usually more than one. Depending on the severity, these can sometimes be repaired; however, in cases of extensive corrosion, a new coil or a complete system replacement is required to guarantee long-term reliability. Once the leaks were detected, the nitrogen was safely evacuated, and the system was isolated and locked off for safety.
Advanced AC Leak Detection Services
Leak testing commercial and domestic units can take anywhere from a few hours to a couple of days, depending on the size of the system and the severity of the leak. We utilize a variety of advanced methods to find them, including injecting UV refrigerant dye into the system and returning with a UV light to illuminate extremely microscopic leaks.
