Why Does My Car AC Smell Like Ammonia?
The unpleasant smell resembling ammonia in a car's air conditioning system can be caused by the accumulation of mold, mildew, and bacteria. This leads to the production of ammonium, a component found in urine.
An additional reason for the ammonia-like odor could be a leakage of refrigerant in the system.
If the ductwork in areas without temperature control, such as the attic, becomes damp, it can also contribute to a musty or ammonia-like scent when the air conditioning is turned on.
The source of the musty or ammonia odor is the presence of "mycotoxins," which are metabolic byproducts of mold and mildew.
What causes the ammonia smell in my car's AC?
If you detect a urine-like odor emanating from your car's air conditioning vents, it is likely due to the accumulation of mold, mildew, and bacteria. The mold produces ammonium, which shares a resemblance to the smell of urine.
This particular smell is primarily caused by the presence of mold on the evaporator coil, which plays a crucial role in regulating the temperature and airflow. As time goes by, moisture in the air can lead to the formation of mold, resulting in a musty odor with hints of ammonia.
If you find yourself encountering this type of smell, it is highly recommended to seek professional cleaning services in order to effectively address the issue.
