Why Is My Car AC Blowing Smelly Air?
There are various reasons as to why the air conditioning system in your car might emit unpleasant odors. Some of the most frequent causes include excessive moisture, a blocked drain pipe, a dirty cabin air filter, an abundance of condensation, and the presence of mold in the vents or on the evaporator coil.
Is there a possibility that mold or mildew has developed in the AC system?
AC units can be a breeding ground for mold due to the circulation of air. Mold spores from a moldy air conditioner can be blown into the air you breathe, spreading throughout your home.
In addition to AC units, mold and mildew can also be present in your HVAC system. When the system is activated, thousands of tiny mold spores can travel through the air ducts and circulate in the air, making them difficult to detect but easy to inhale.

Why does my air conditioner have a bad compressor?
If your air conditioner is not functioning properly, it may be due to a faulty compressor or other worn-out internal components. The compressor is responsible for pressurizing the refrigerant, a cooling agent, in order to convert warm air into cold air. Here are six indications of a malfunctioning air conditioner compressor.
Firstly, if your air conditioner is blowing warmer air than it should, it could be a sign that the compressor is not working effectively. Moreover, if you notice unusual noises, such as clicking or grinding, coming from your air conditioner, the compressor could be at fault. Additionally, if you experience frequent cycles of your air conditioner turning on and off, the compressor may be malfunctioning as well.
Furthermore, leaking refrigerant can be a clear indication of a failing compressor. Inadequate airflow or reduced cooling capacity are also potential signs that the compressor is not functioning properly. Lastly, if you notice an increase in your energy bills without any change in usage, it could be due to an inefficient compressor.
What causes a compressor to burn out?
Electrical issues are a frequent cause of compressor failure, with power surges from the connected source leading to acid buildup. This buildup causes the temperature in the compressor's discharge area to rise abnormally, ultimately resulting in compressor burnout.
Could the odor be coming from contaminated or old refrigerant?
There are several reasons why your fridge might have a bad smell. One possibility is the use of strong cleaning products that may have seeped into the plastic components inside the fridge.
If the smell is not caused by cleaning products, it could be due to a refrigerant leak. This can result in a chemical-like odor.
Decaying food is another common cause of unpleasant odors in fridges, as certain foods can produce strong smells as they rot.
In addition, old ice can develop a stale odor over time.
An additional factor to consider is outgassing, which can occur when certain materials in the fridge emit odorous substances.
