Why Does My Car AC Smell Like Cat Pee?

The unpleasant odor in your car's air conditioning system is likely caused by a buildup of bacteria, mold, or mildew in the vents and AC system.

This mold produces ammonium, a chemical also found in urine, which is responsible for the odor you are smelling.

The most common reasons for a urine-like smell in your car are mold and bacteria blocking the system, a dirty cabin air filter, or the release of fumes.

In rare cases, the intake of small animals into the system can also be a cause.

Is there a problem with my car's air conditioning system causing it to emit a cat urine odor?

If your vehicle's air conditioner emits a foul odor resembling cat urine, it is likely due to the presence of bacteria and mold within the system. The air conditioning system includes an "evaporator" component, which works to cool the air by eliminating heat and moisture from the car's interior. Even in low humidity conditions, there is still enough moisture for condensation to occur on the evaporator, providing an environment for mold and bacteria growth.

The growth of mold results in the production of ammonium, which is also present in urine, leading to the unpleasant odor that you are experiencing. Additionally, factors such as the release of fumes, accumulation of dirt in the cabin air filter, and the entry of small animals into the system can also contribute to the presence of a urine-like smell in your car.
