Probably one of the reasons why there is a distinct smell in your air conditioner when you turn it on is the growth of mold in your air vents. As the car becomes older, bacteria, mold, fungi, and micro-organisms can start to grow. The growth of these bacteria is often behind the dash panel on the evaporator.
Why does my car smell bad when I turn on the AC?

Where is the air intake vent on a car?
A: The heating-and-ventilation air intake on most vehicles is at the base of the windshield. This location provides optimum airflow to the cabin while the vehicle is moving.

Why does my AC smell when I first turn it on?
Dust, hair, and moisture on the AC filter encourage mildew growth, which can cause a musty odor when the air conditioner runs. This is a likely reason why the air conditioner smells when first turned on if you don’t use forced-air heating in winter. To help prevent this odor, clean or replace the filter in the spring.
Why does my AC smell like sewer?
Like with a rotten egg smell, a sewage smell coming from your air conditioner can indicate a hazardous cause. If you smell sewage when you turn on your A/C unit, your sewer system may have backed up into your house or near your unit, and the smell may come from a ruptured pipe.
Do car AC cleaners work?
Air conditioning aerosol ‘bomb’ cleaners cannot be effective, unless the evaporator is dried, first. The aerosol’s contents should pass through and disinfect the air ducts. Replacing the pollen filter afterwards is a prudent move, too. On my experience, air conditioning ‘bombs’ are effective, if used regularly (approx.
Does car AC take air from outside?
When activated, the car’s air conditioning system recirculates the air inside the car for cooling, instead of using air intake from the outside. Recirculating air, especially on a hot day, will cool down the inside of the car quicker and put less stress on the car’s blower motor and air compressor.

Recirculating cooled air, rather than bringing in fresh outside air, can cool down your vehicle faster. The longer it’s on, the cooler your car gets.
Why is my car AC not ice cold?
