Detecting leaks in the Air Conditioning Unit immediately

Detecting leaks in the Air Conditioning Unit immediately

Let’s try to hazard a guess on why it is important to look out for leaks in your air conditioning unit. Firstly, it is a matter that is extremely important for your health. You definitely do not want to be breathing in air that is unhealthy from the unit.

If that doesn’t convince you on why you need to detect such leaks, let’s think about the cost of replacing the refrigerant which leaks from the air conditioning unit. If your system requires R-22 refrigerant, this can cost anywhere from $50 to $200 a pound. And mark you, the price of repairing the leak hasn’t been factored into this.

Therefore, because of the cost to you financially and the impact to your health, you want to always be on the lookout to discover whether your air conditioning unit is leaking.

Causes of Leaks in Air Conditioning Unit

A leak in the Air Conditioning Unit is usually because there are holes or cracks in the coils which circulate the refrigerant. Hissing sounds could be a sign of many problems including a leak. Larger leaks may sound like a man struggling to breath and producing a gurgling sound.

The most common cause of water leaking from the air conditioning unit is a clogged condensate drain line. As we pointed out in a previous article, clogs in the air conditioning unit can come from dust and dirt particles or even mold. The air conditioning unit can be unclogged by using a vacuum pump before filling up the refrigerant. This is something that the air technician who has a good vacuum pump can do very easily.

Detection of Leaks in the Air Conditioning Unit

Leaks are no longer detected by using soap bubbles and water. Have you ever visited a tyre technician who dumps your tyre into a basin of water and rolls it around to find the leaks? That’s kind of the way it used to be done for the Air Conditioning Unit. But systems are sophisticated nowadays and bubbles will not always pinpoint the leaks.

Since soap and water are no longer commonly used for detection, technicians come with more sophisticated equipment. One of these is the Halide leak detector. It is designed to locate leaks from the refrigerant gases.
