The Symptoms

What are the common freon leak symptoms?

  • Frozen evaporator coils. If you see any water pooling close to the AC unit or you see frozen evaporator coils, you need to contact a professional service right away.
  • Gurgling or hissing sound (from the AC). A gurgling sound typically shows that the leak is quite big, while a hissing sound tends to show small leaks.
  • The AC doesn’t generate cool air anymore. If the AC still runs and operates, but it doesn’t feel cool, then you should contact a professional. They can check whether there is a leak or not.
  • Electricity bills spike – and it happens suddenly. This usually happens because the leak causes too much stress on the AC.
  • Elongated cooling cycles. You should be suspicious if the AC runs, but it takes forever to make your house cooler. A normal AC only takes a short time to cool a room off.
  • Increased humidity. Not only it take forever to cool a room off, but humidity also increases. In fact, you should realize that the humidity level increases.
  • You have an exhaust-like smell in the air. It can be somewhat chemical-ish. If you notice this, get assistance as soon as possible.

Refrigerant Leak Smell Dangerous

You should know that freon is dangerous and pretty toxic. It is known as freon or refrigerant poisoning. When you inhale it deeply, it is able to cut the oxygen off to your lungs and cells. If the leak happens for quite a while, it can cause brain damage. In some severe exposure cases, the result can be death.

Limited exposure (like breathing close to an open container or a spill on the skin) is considered mildly dangerous. If you inhale a high ‘dosage’ of freon (and you do it repeatedly), you can suffer from the following:

  • Organ damage
  • Breathing difficulty
  • Fluid buildup within the lungs

No matter what, it’s imperative that it’s best to avoid any contact with the chemicals, regardless of the quantity. Small amounts may cause symptoms, especially for those who are sensitive.

Poisoning symptoms include:

  • Vomiting
  • Nausea
  • Irritation (to the throat, ears, and eyes)
  • Headache
  • Cough
  • Dizziness
  • Chemical burn (to the skin)
  • Frostbite

If you experience those symptoms and you are aware of the leaky freon issue at home (or around the area where you are usually present), you should get medical care right away. You can go to the doctor or even the ER, especially if the symptoms are heavy.

Conclusion

Don’t underestimate the case of leaky freon. Not only it will affect your bills, but it can also affect your health. Now that you know the answer to what a freon leak smell like, you can be more aware of your surroundings.
