What is the smell of freon?

Freon is a brand name generally used for refrigerants or chlorofluorocarbons used in air conditioners. These are of various types like R-22, R134a, R404a, R290, etc., and every one of them smells different from others. Apart from that, it is proven through research that the sense of smell is different for every person as it depends upon the number of receptors in your nasal cavity.

For me, the smell of freon was slightly sweet and aromatic, but most people find it to be a sweet chloroform kind of smell. Well, some people also think of it, as Google suggests, as ammonia, cat urine, acetone, rotten eggs, propane kind of smell. Many may even confuse the smell with that of some kind of mold buildup.

R22 is the most potent kind of freon, which is damaging to humans and the environment. There was a ban on using this freon as a refrigerant for air conditioners. The law made for its ban is not used throughout the world, and new products now contain freons that are a little better for the environment yet lethal for humanity.

Does Freon Smell Like Paint?

Everyone has a different perception of smells and what smells like paint for some people might be completely odorless for others. However, there are individuals who claim that a refrigerant leak does smell like paint thinner.

If you haven’t been painting anything in the house, but you have noticed a smell of paint coming from the air conditioner, then the chances are high that there is a refrigerant leak.

Of course, you would have to get the unit inspected by a professional as soon as possible.

How do I know if I have a refrigerant leak?

What happens when you smell freon?

Freon is a tasteless, mostly odorless gas. When it is deeply inhaled, it can cut off vital oxygen to your cells and lungs. Limited exposure — for example, a spill on your skin or breathing near an open container — is only mildly harmful. However, you should try to avoid all contact with these types of chemicals.

Why do I smell Freon?

Refrigerant is the lifeblood of your air conditioner. … Over time, sometimes these copper coils crack and leak refrigerant. Refrigerant has a sweet, chloroform scent, so that could be the chemical odor you’re smelling.

Does freon smell like natural gas?

At room temperature, freon is a colorless, almost odorless gas that is four times heavier than air. The ether-like odor that freon emits will almost immediately sink to the floor. Therefore, the chance of smelling freon during an air conditioning leak is very small.

Is Freon Dangerous To Breathe In?

Despite what we’ve covered here and all the opinions of what Freon smells like, Healthline says that “Freon is a tasteless, mostly odorless gas”.

Indiscriminate amounts of refrigerant that get inhaled are mainly harmless, thank goodness, since that occurs quite often in just bleeding refrigeration hoses.

Refrigerant poisoning is not an frequently occurring event, except in cases of abuse. Huffing, or inhaling Freon in an attempt to get high. These chemicals can give the inhaling person what’s described as a pleasurable feeling.

I had a customer call that had a heat pump problem. When I checked out his system I found it to be completely flat or out of refrigerant. I pressurized the system with nitrogen and found no leaks. I drew a vacuum and still no leaks.

This was a rental for my customer and he knew a relative of the renter and suspected him of huffing the Freon from the system. Or he could have just dumped it out of meanness or retaliation for something.

Recent codes have made it a requirement to add locks to the service ports of new installations. But homeowners that want to protect their valuable refrigerant from being stolen by some huffer can easily install these locks on there own systems.

If you have a heat pump then you will need three locks. Air conditioners will only need two. As you can see you get your own key. Just remove existing caps and replace with these locks and tighten with the key.

Toxic Freon Leaks

Freon is a chlorofluorocarbon (CFC) that helps the AC remove heat from the atmosphere to keep you cool, but can be harmful to people if it is not contained properly. Freon usually travels through closed copper coils in an AC unit, but these coils can crack and result in an AC coolant leak. A freon leak will produce a smell between sweet and chloroform.

Freon leaks can be toxic. If you suspect a freon leak, talk to a specialist who can use a freon leak detector to help address the issue.

How Long Does Freon Stay in the Air?

Let’s imagine that you have had a major refrigerant leak in your house. How long will it take the Freon to disappear?

There is no single answer to this question as the timeframe is going to depend on how well-ventilated your house is.

In any case, it is always better to call a team of professionals, so that they can take care of the problem and make sure that the space is safe again.

What you can do yourself, is open the windows and doors and turn on the fan (if you have one). This will help the air in the room get renewed a bit faster.

Sign and Symptoms of Freon Leak

The common signs and symptoms that you will observe during a freon leak depend upon the size of the leakage. You will face the following signs and symptoms;

• Headache
• Nausea
• Dizziness
• Difficulty in breathing
• Burning sensation on your ear, nose, lips, and eyes
• Vision loss
• Ingestion
• Diarrhea
• Severe stomach pain

If there is a freon leak, that is an indication that your air conditioner is not doing well and is in the last stages of well-being. Once you repair that leak, there will be another one just a few days after or a month later, so it’s better to change your AC than taking risks.
