Refrigerant Leak Detection in Carthage, NC

A refrigerant leak usually comes from a small crack in the outdoor coil, a loose fitting, or wear at a connection point in the line set. It’s rarely a sign the refrigerant was simply used up, since a properly sealed system doesn’t lose charge on its own.

Common signs include reduced heating or cooling performance, ice forming on the outdoor unit, longer run times without keeping up with the thermostat setting, or a hissing sound near the unit. A technician confirms the diagnosis with testing equipment rather than the symptoms alone.

In most cases, the specific leak point, a fitting, a coil, or a section of line set, can be repaired and the system recharged. Replacement usually only comes up when the leak is tied to a coil that’s failing in multiple places or a system that’s already near the end of its service life.

No. Adding refrigerant without finding and repairing the leak means the system loses that charge again, sometimes within weeks. Locating the actual leak point is the first step, and the recharge happens after that repair is complete.

Yes. A maintenance visit includes checking refrigerant levels and inspecting coils and connections, which is often how a small leak gets caught early instead of during a breakdown.
