When you turn the A/C on, on a hot day, it should cool the entire cabin and make your feel comfortable. There should be nothing inexplicable.
If you have started noticing smells from the car A/C, there could be a number of reasons behind it.
However, the real reason behind the smell primarily depends on what type of smell it is.
Common Causes Of Bad Odors
Most car owners tend to smell a musty sort of smell, more like a dirty pair of socks. If that is the case, there is a lot of mildew depositing in the system and it is not really too big of a problem. In fact, this is the most common problem behind car A/C smells.
This smell usually occurs when you turn the A/C on and use it solely on re-circulate. After using for a while, you quickly turn off the engine without turning the fan on for a few minutes. This leads to mold and mildew growth in the entire system leading to a musty smell.
Even though mildew can be there in most parts of the A/C system, you will typically see it on the condenser or the evaporator core. These are the areas that are mostly moist and sealed, making the perfect habitat for bacteria growth. Even though it isn’t really too much of a problem, the smell can certainly keep you from using the A/C.
Preventing Bad Smells
Even though there are several ways a car A/C repair technician will use to solve this problem, a good approach is to prevent it from occurring in the first place.
When you use the A/C, keep switching between re-circulation and fresh air.
Moreover, you should also turn the fan on for at least a few minutes before turning the engine off. This will help keep the entire system dry and minimize chances of mildew deposits.
An A/C repair expert can also solve this issue by spraying a disinfectant through the fresh air intake.
Another thing you should do is change the cabin filter as any air entering the cabin passes through here.
