How to Remove the Air Conditioner Smell in Your Car

Do you rely on your car’s air conditioner during the hot summer months?

Does it ever produce a musty smell?

When you get in your car after being out in the hot sun, the last thing you want is your air conditioner (AC) to blow out air that smells like wet socks. If this happens in your car, don’t worry—it’s common and easy to fix.

What Causes Air Conditioner Smell?

Musty smells are often caused by poor ventilation and excess moisture. This is the case with your car’s AC. The “evaporator,” which cycles refrigerant (the stuff that makes the cold air) through your AC system. Sometimes moisture builds up in the evaporator, and if it doesn’t exit through the evaporator drain, it will just sit there. This condensation is what creates the bad AC smell.

How Do I Get Rid of Bad AC Smell?

Getting rid of the bad smell is easy; all you need is a disinfectant spray.

Open your windows and set the car fans on a low setting, then spray disinfectant into your vents. The fans will circulate the disinfectant through the system and kill the bacteria causing the smell. Let the car continue airing out for a few minutes after spraying.

Can I Prevent the Smell Before it Happens?

Consumerreports.org recommends running your car fans without the AC for a few minutes before turning the car off; this can help get rid of excess moisture and prevent your AC from being smelly. The musty smell can also be caused by a dirty cabin air filter. Having ArborMotion install a clean filter can also help.
