With the arrival of spring and the approaching heat of summer, it’s time to start thinking about getting your air conditioner serviced. If you don’t pay a professional to undertake routine maintenance, you may have to deal with costly disruptions in the future. Leaks in the refrigerant system are a common cause of AC failure.

If your air conditioner has a refrigerant leak, it will take longer to chill your home and cost more to run. Read on if you’re curious about the most common sites of refrigerant leakage. In this piece, we’ll discuss three typical A/C leak points and how to fix them.

• Capillary Tube:

The simplest form of throttling device is the capillary tube. In addition to being a common component in central air conditioners, capillary tubes can also be found in portable refrigerators and other small cooling machines. The capillary tube is usually located in the air conditioner’s condenser unit, the huge cubical component of your system that is typically located in the backyard.

An appropriate pressure is maintained for the refrigerant as it travels through a capillary tube to the evaporator in your home. The fluid is sent via a long, coiled copper tube to accomplish this. Since the refrigerant can’t flow as freely through a tube of smaller diameter, the pressure on the inside of the tube rises.

Due to their brittle nature, capillary tubes often leak refrigerant. The continual vibrations produced by the condenser’s motor can cause the mounting hardware for a capillary tube to become dislodged. Then, the free tube starts rubbing on neighbouring metal. The soft copper will wear away quickly due to the friction, leaving behind tiny holes.

• Flare Fitting:

Anywhere a capillary tube or other segment of metal tubing connects to an HVAC component, you’ll find a flare fitting. There is a significant risk of leakage at these fastenings. When the flare nut of a fitting is tightened, it squeezes the tubing’s end, sealing off any potential leaks.

However, flare fittings often experience their own issues with time. Flare fittings, like the hardware used to attach capillary tubes, can become loose due to vibration over time. If the flare nut loosens up too much, refrigerant will seep out.

In many cases, simply tightening the nut on a leaking flare fitting can fix the problem. However, a tube end that has been crushed too much can sometimes be the source of the issue. Leaks will persist no matter how securely you tighten the flare fitting. In this case, either the tubing or the flare nut needs to be changed entirely.

• Evaporator Coil:

The evaporator coil in your air conditioner is what does the actual work of cooling the air in your home. In your home’s air handler is where you’ll find the evaporator coil. From the outdoor condenser, liquid refrigerant makes its way to the indoor evaporator coil. The refrigerant draws heat from the air as it circulates around the coil.

Condensation commonly occurs on the exterior of the coil when the air rapidly cools. Formic acid can be produced from this condensation when it combines with volatile organic chemicals in your home’s air. Soon, holes will emerge in the copper evaporator coil as the formic acid eats away at it and the refrigerant leaks out.

It’s best to have a professional handle the difficult work of locating a refrigerant leak. Other leaks like aircon leaking water can also occur so make sure to services your aircon regularly.

Different Types of Refrigerant Leaks in Aircon:

Due to the diversity of refrigerant leaks, pinpointing the source of a leaking Freon supply can be a difficult task. Some of the Types are as follows:

• Standing Leak – A typical type of leak is a standing leak (SL). When the AC is turned off, you can easily spot an SL.
• Pressure Dependent Leak – Another type of leak, known as a pressure dependent leak (PDL), is uncovered when the cooling system’s pressure rises.
• Temperature Dependent Leaks – While the condenser becomes blocked, when the system is defrosting, or when the ambient temperature is very high, temperature-dependent leaks (TDL) occur. This generates a great deal of heat.
• Vibration Dependent Leakage – Another kind, called vibration-dependent leakage (VDLs), occurs only when the machine is in use. Mechanical motion is required for refrigerant leakage to occur in VDLs. Leaks based on vibration might develop in the refrigerant piping if it constantly scrapes against other parts of the system.
• Combination Dependent Leak – To have a combination dependent leak (CDL) means that the leakage is caused by two or more independent variables.
• Cumulative Miccro Leaks – Finally, there are the microscopic leaks that can form over years of operations and repairs and are known as cumulative micro-leaks (CMLs).

Thus, it is very important to check up on your AC for problems because refrigerant leaks are not the o bly issue.
