Charlotte Air Conditioning Repair Tip: How a Refrigerant Leak is Detected

Posted by Chris Allen

A refrigerant leak represents a significant problem with your air conditioning. A lack of refrigerant means that the AC must work harder to cool your house and eventually may not blow any cool air at all. That could spell trouble in Charlotte, NC, where air conditioning is necessary to stave off the heat and humidity of summer. Refrigerant circulates throughout a closed system that ideally shouldn’t spring any leaks, but unforeseen damage and normal wear and tear can change that. Homeowners may wonder how a refrigerant leak is detected; in most cases, it involves a trained technician who knows what to look for.

The first sign of a possible refrigerant leak comes when the AC is on and the fan is blowing, but no cool air is coming out. That may stem from a number of different causes, however, so the technician must do more. He or she will open up the system and check the cooling and condensing coils. In some cases, ice may form on the coils, which indicates lowered refrigerant levels. There may also be signs of corrosion or breaks in the coils, poorly soldered fittings or stains that may indicate a previous history of leaks.

These signs can usually be spotted with the naked eye, though again, it takes a trained technician to know what to look for. The next step is to gain a more accurate idea of the source of the leak. Most service technicians use a halogen leak detector: a sensitive tool that reads the amount of halogen gas in the atmosphere and can help pinpoint concentrations that may indicate a leak. Detecting such a leak is a vital step in the repair process, and a professional service tech should pinpoint it and seal it up before recharging the refrigerant. Otherwise, he’s just temporarily alleviating the symptoms.
