How to Get Bacteria Out of Your Car AC

How to Get Bacteria Out of Your Car A/C

Your car's air conditioning system can accumulate bacteria that causes damage not only to the A/C system, but also to you and your health.

Time to get it serviced!

Due to old age and lack of proper maintenance, mould, mildew, fungi and micro-organisms can start to grow in your car’s AC.

The growth of bacteria can cause an unpleasant odour when you turn on your car’s air conditioning system.

Mould and mildew

Mould and mildew are the common sources of bacteria in your car’s air conditioner.

They grow due to moisture (caused by condensation, humidity, or any water leakage inside the car), and lack of airflow.

Your air conditioner becomes the breeding ground of mould and mildew, especially when it’s turned on.

What are the signs?

Mold and mildew are common sources of bacteria in your car’s AC. They thrive on moisture from condensation, humidity, or leaks, especially when airflow is poor.

If it’s been over a year since your last service, there’s a good chance your AC’s full of dirt and bacteria.

Look out for the following signs to know if your car’s AC needs a thorough, anti-bacterial clean:

Bad odour
Lack of cold air blowing from the air conditioner vents
The feeling of suffocation

Common health issues

Bacteria builds up in your car’s AC when air brings in mold and germs through the vents and evaporator.

With the windows closed and AC on, you’re breathing that same air—bacteria and all.

This can lead to anything from minor headaches, drowsiness, a stuffy nose or a cold, to more serious issues that allergic reactions or bacterial infections.

What You Can Do Yourself

Your car’s AC is constantly exposed to dust, dirt, and moisture, so bacteria naturally build up.

The good news? You can tackle common culprits like mold, mildew, and grime.

Antibacterial Spray

Use an anti-bacterial spray to temporarily kill bacteria in your car. Just make sure no one’s inside, and give it 30 to 60 minutes before hopping back in.

Clean the Vents

Another quick way to clean your AC is by wiping the vents with a cloth soaked in vinegar. Baking soda works too if that’s more your vibe.

Clean/replace the Filter

Cleaning or replacing your air filter helps get rid of mold and bacteria in your car’s AC. It’s best to swap it out every two years.

Get a Professional In

If you think your car’s air conditioning unit has accumulated too much dirt and bacteria, it’s best to have your A/C checked by a professional for a cleaning service.

Motorama has car air conditioning experts that have the necessary tools and skills to effectively remove mould and mildew from your air conditioner, making it safe for your health.

Preventing Future Bacteria Growth

There are ways to prevent bacterial growth in your car’s AC. First, you should keep the car interior clean – remove all rubbish, wash and change the floor mats regularly.

Even if you don’t regularly use your car, always wipe the vents clean and turn on the car’s air conditioning weekly for at least 10 minutes. Also, run the defrost setting after long periods of use.

Most importantly, the best way to prevent bacteria and mould from building up in your car air conditioning unit is to have it regularly serviced. In our experience, your car’s air conditioner should be checked and cleaned at least once a year.
