AC Refrigerant Leak Repair in Islamabad – Detection and Fix

A refrigerant leak is the root cause behind most AC gas refill requirements. Gas does not run out naturally; it leaks. Simply refilling without finding the leak is money wasted: the gas will escape again in weeks or months. AF Tech Fix always finds and fixes the leak before refilling.

Signs of refrigerant leak in Islamabad ACs

Poor cooling despite running. Ice forming on copper pipes or indoor coil. Frost on the outdoor unit service valves. Hissing sound near the unit or piping. Unusually high electricity bill as the compressor runs continuously trying to reach target temperature. Oil stains near pipe joints (refrigerant oil escapes with the gas).

How AF Tech Fix detects refrigerant leaks

Step 1: Electronic leak detector swept along all pipe joints, valve connections, and coil surfaces. Step 2: Soap solution applied to suspected leak points for visual confirmation. Step 3: Nitrogen pressure test of the sealed system to identify pressure drop. This three-step approach ensures no leak point is missed.

Common refrigerant leak locations in Islamabad ACs

Flare joints at the indoor unit service valves (caused by incorrect torque at installation). Pipe joints in concealed runs where the pipe was bent sharply during installation. Outdoor unit service valve packing (common in units more than 5 years old). Indoor coil hairline cracks (rare but seen in units with history of overcharging).
