Freon is odorless, but it is possible to smell the refrigerant oil that could also be leaking.
Freon is odorless; you cannot smell it.
Freon mixed with refrigerate oil will have a slight smell.................
Freon could be leaking anywhere in the ac system. A colored dye can be added to the system, then seen with a special light to find the leak.
A Freon leak can cause you headaches and nausea but not cause severe health issues. You should have the leak repaired by a qualified professional as soon as possible.
If you smell gas from your vehicle it probably indicates a leak. Even a tiny leak will produce a fuel smell. If there is nothing obvious leaking from the fuel lines, pull the vacuum hose off the fuel pressure regulator, if there is any smell of fuel there or if gas is present, it is leaking and needs to be replaced.
No, it should not leak freon because it is supposed to be a sealed unit.
AnswerYou probably have mold growing in the system. You should be able to find something at the auto parts store to kill it off. To keep it from coming back, you should always run the fan (even if just on the lowest setting) to keep moisture from building up in the system. Leaking freon from your evap. may cause a smell if you have a substantual leak.
There are lots of places that can leak freon and some can be sealed with stop leak. The only way is to try it.
I don't know how to solve the odor problem, but I can give you an idea on detecting the freon leak. If the leak is not visually apparent, the next time you add freon, use one can of freon with leak detector. It is usally red in color and you will be able to see where it leaks from.
If it leaks it leaks. Central units are self contained with no external rotating shaft seals to leak. If the tech came out and added freon without detectng the leak, either he did exactly what you directed, or he is a BS artist hoping for a repeat job.
The rubbing alcohol smell can indicate a Freon leak. The smell can also indicate a plugged drain tube. There is natural condensation that needs to drain away from the air conditioning compressor.
Chances are your leaking freon. There may be a leak in one of the seals.
