The Sign, Cause & Danger of Aircon Gas Leak

A gas leak is a potentially deadly situation. If you smell gas or suspect there may be a gas leak in your home, it is important to take action right away. Do not try to fix the problem yourself; call a professional immediately. This article will discuss the signs of a gas leak, the cause of gas leaks, and the dangers of gas leaks.

‍5 Signs of a Gas Leak in AC

Your Air Conditioner Makes a Hissing Noise

A sudden hissing sound coming from your air conditioner is one of the most clear-cut signs that you have a gas leak in your AC system. The refrigerant that circulates through your AC system is pressurized, so when it starts escaping through a hole or crack in one of the cooling pipes, it creates a hissing noise.

‍Aircon Not Cooling

One of the most common signs that your AC unit has a refrigerant gas leak is insufficient cooling. If your unit isn’t cooling the air properly, it’s likely because it doesn’t have enough coolant. Your AC may also start short cycling – turning on and off at short intervals. Another telltale sign of a gas leak is warm air coming from the unit instead of cold air.

Frozen Evaporator Coils

One of the most common signs that you have a gas leak in your AC unit is if your evaporator coils freeze up. The evaporator coil is responsible for absorbing heat from the air inside your home, and when it freezes, it can no longer do its job properly.

In addition to causing your AC unit to work less efficiently, a frozen evaporator coil can also damage the unit itself. If you notice that your evaporator coil is starting to freeze, you should turn off your AC unit and let the ice thaw.

Once the ice has thawed, you can inspect your unit for any hissing sounds or sweet smells that would indicate a gas leak. If you find either of these signs, you should call a professional to repair the leak as soon as possible.

High Electricity Bills

If your AC is using more energy than normal, it could be a sign of a refrigerant leak. When your AC system is low on coolant, it has to work harder to provide the same level of cooling, which uses up more energy and causes your bills to go up.

Air Conditioner Smells Sweet

The sweet, chloroform-like smell of refrigerant gas leaks is a telltale sign that something is wrong with your AC unit. If you notice this smell, it’s important to take action right away. First, unplug your AC unit to avoid any further damage. Then, contact a technician to find and fix the gas leaks. Ignoring the problem will only worsen, and it could even lead to a fire if the electrical wiring is on the fritz.

The Causes of Aircon Gas Leaking

Many homeowners in Singapore have problems with leaks. There are several things that can cause a leak.

Corrosion

The causes of aircon gas leaks can be attributed to many different things, but one of the most common is corrosion. When metal is exposed to oxygen, it begins to corrode and break down. This process is accelerated by exposure to certain elements, such as fluorides and chlorides. Over time, corrosion can cause tiny holes to form in metal surfaces, which can lead to leaks. In the case of air conditioners, these leaks can allow refrigerant gas to escape. As a result, it is important to be aware of the potential causes of air conditioner gas leaks to prevent them from occurring.

Mechanical Damage on Refrigerant Lines

One of the most common causes of an aircon gas leak is mechanical damage to the refrigerant lines. These lines are responsible for moving the refrigerant between the evaporator and condenser. Damage to these lines can cause a leak, and this is especially true for lines that pass through the exterior house wall.

Faulty Compressor

In addition to mechanical damage, another common cause of an aircon gas leak is a faulty compressor. The compressor is responsible for pressurizing the refrigerant, and a leak can occur if it is not working properly.

A malfunctioning Schrader Valve

The Schrader valve is located near the air conditioner’s compressor, and its purpose is to regulate the flow of refrigerant gas. However, if the seal covering the valve becomes damaged, it can cause refrigerant gas to leak out. In addition, if the valve itself is not functioning properly, it can also lead to gas leaks. As a result, it is important to have the Schrader valve inspected by a qualified technician on a regular basis to ensure that it is in good working order.

Faulty Seals & Leaky Connections around Control Valves

Faulty seals can cause refrigerants to escape, leading to a drop in air pressure and decreased cooling performance. On the other hand, leaky connections around control valves can allow refrigerants to leak out slowly over time. You can do a few things to make sure your air conditioner doesn’t have this problem. Make sure the valve is attached correctly and is clean. You should also do regular maintenance and inspection of your air conditioner to find any potential issues before they become serious.

The Danger of Aircon Gas Leaking

While a small leak may not seem like a big deal, it can actually be quite dangerous. The refrigerant gas is highly flammable, and if it comes into contact with an ignition source, it can cause a fire. In addition, the refrigerant gas is also toxic, and inhaling it can be harmful to your health. Below are some of the dangers of aircon gas leaking:

  • Harmful to Health: When gas leaks out of an air conditioner, it can be dangerous for people. There are two main dangers: first, people can get headaches or feel sick from the gas. Second, if someone is exposed to the CFCs in the gas for a long time, they can get frostbite.

    Short-term exposure to this gas can result in skin cracking, trembling, poor coordination, increased heart rate, convulsions, and other problems. Gas poisoning can induce severe medical issues, including unconsciousness, restricted breathing, and heart rhythm abnormalities that might lead to cardiac arrest and death.

    Inhalation of Freon can also damage your liver, kidneys, and central nervous system. That’s why it’s vital to have qualified personnel repair any leaks in your air conditioning unit as soon as possible.
  • Aircon Damage: Studies have shown that a leaking air conditioner can increase your electricity bill by as much as 20%. If you continue to use a leaking air conditioner, the compressor will eventually break down from the increased pressure. And replacing a compressor is much more expensive than repairing a leak.
  • Fire & Explosion: As we mentioned earlier, Freon is highly flammable. If it comes into contact with an ignition source, such as a lit cigarette, it can cause a fire or explosion.

10 Spots to Find AC Leak

Final Thoughts

Aircon gas leaking can be a severe problem that can lead to health hazards, damage to your AC unit, and even fires or explosions. That’s why it’s essential to take measures to prevent leaks from happening in the first place. Be sure to have your AC unit installed by a qualified technician and have it serviced regularly.

In addition, keep an eye on the Schrader valve and other control valves to make sure they are functioning correctly. By taking these precautions, you can help to prevent leaks from happening in the first place.
