Freon Leak Repair — AC Refrigerant Leak Detection

Professional Freon Leak Repair — AC Refrigerant Leak Detection in Asheville & Western NC

A Sealed System Should Never Lose Refrigerant

Your AC operates as a closed loop — refrigerant circulates continuously but is never used up. A low charge means one thing: there is a leak. Topping off refrigerant without tracking down and sealing the leak is like adding water to a leaking pipe — you will be paying for another recharge in weeks or months, and the compressor suffers progressive damage every time the charge drops. Quality Mechanical does it the right way: locate the leak, repair it, then recharge to specification.

Professional Leak Detection Techniques

Refrigerant leaks can be notoriously hard to find. Some are pinhole-sized and only weep under operating pressure. We employ multiple detection approaches matched to the situation: electronic refrigerant detectors that sense trace molecules in the air near a leak, UV fluorescent dye injected into the system and revealed under ultraviolet light, nitrogen pressure testing, and soap-bubble testing on accessible joints and connections. The best method depends on the suspected location of the leak.

Repair the Leak or Replace the Component

Once the leak is found, certain types can be sealed with brazing — especially leaks at solder joints, service valve connections, or accessible tubing. Leaks inside the evaporator coil or condenser coil usually mean the coil itself needs replacement, since internal leaks tend to reappear. We outline your options clearly and help you choose between a targeted fix and a more comprehensive solution based on the system's age and overall condition.
