A chemical odor, frequently accompanied by a moldy smell, usually indicates the AC evaporator itself is leaking refrigerant. Because the evaporator is usually tucked up under the instrument panel, this repair should be done by your mechanic.
Can air conditioners give off toxic fumes?
The truth is air conditioners do not emit any gases during operation. However, if the air conditioning copper pipe is not brazed properly, the refrigerant flowing inside the copper pipe can leak to the surrounding through brazing cracks. The refrigerant is harmful to both humans and the environment.

How do I know if my AC is leaking freon?
Signs Your AC Is Leaking Freon Low Airflow. When your air conditioning system is low on refrigerant, it won’t produce as much cool air as it usually does. AC Blowing Warm Air. Ice Build-Up on the Copper Lines or Evaporator Coil. High Electric Bills. Your House Takes Longer to Cool Down.
Can a freon leak in your car make you sick?
While tasteless and odorless, Freon does make a large impact on your air and health. Refrigerant poisoning is a serious condition that can lead to difficulty breathing, headaches, nausea and vomiting, skin and eye irritation, and coughing.

How long does it take to get Freon poisoning?
acute effects occur within minutes to 24 hours. subacute effects appear 24 hours to 2 weeks after exposure.
Can Freon explode?
Freon is compressed into self-pressure-releasing cylinders that may rupture because of extended exposure to fires over 900 degrees Celsius. Freon itself does not catch fire, but the cylinders containing the gas may explode if the fire is not controlled.
How long does Freon poisoning last?
How well a person does depends on the severity of the poisoning and how quickly medical help was received. Severe lung damage may occur.

Why does my car AC smell when I first turn it on?

How do I check for a Freon leak?
Dye Detection One of the more effective ways to check for a refrigerant leak in your air conditioning system is to conduct a dye test. This process involves sending fluorescent dye into your HVAC system. After it has enough time to circulate, the dye will pour through any leaks that are present.
Is R134a toxic to humans?
The inhalation of high concentrations of R134a vapour may cause temporary central nervous system depression, with narcosis, lethargy and anaesthetic effects. Continued breathing of high concentrations of R134a vapours may produce cardiac irregularities, unconsciousness and death.
Is AC Freon flammable?
Although freons such as CFCs or HCFCs are not flammable at normal temperatures, it should not be said that they are not dangerous. It can also be the cause of explosions sometimes. Freon is kept in a gaseous form at high pressure in a gas cylinder.
