Best practices to help prevent that musty odor from developing in your vehicle's A/C

Best practices to help prevent that musty odor from developing in your vehicle's A/C


An unpleasant or musty smell coming from your air conditioner can have a direct impact on your health and mood. Musty odors are due to several factors. Moisture is the building block for mold and mildew growth, which can cause a musty smell from your vehicle’s air conditioner.


Clean your ventilation system

Use a non-corrosive evaporator cleaner, Clean Air Evaporator Cleaner is a foaming detergent that will penetrate deep into your car's evaporator and breakdown the mold and other culprits that are causing the odor. This cleaner will not only eliminate the odor, but, it will also increase the evaporator's efficiency allowing you to have cooler air


 Keep it clean!

You can clean the air conditioner using an effective evaporator foam cleaner such as DWD2 Clean Air Evaporator Cleaner, However, taking certain precautions can extend the benefits you get from a clean ventilation system and reduce the frequency of maintenance required to maintain a fresh AC . Below are some steps that you can take to help preventing a mildew odor to develop in your AC.


Run your AC regularly

Even if you prefer to keep your windows down for fresh air instead of running your Ac, you'll want to turn on the AC now and then. The reason is so you can clear out the dust, buildup, and general staleness from your system. We recommend you dial it up to full blast now and then and leave it there for about 10 minutes. It is also vital because the refrigerant circulates the lubricating oil in the system, which keeps vital parts lubricated and keeps the system's seals from drying out.


Switch between fresh & recycled air

Switch between fresh air and recirculated air to help keep your car’s ventilation system dry. Switching between the two will cut down on the condensation buildup on the evaporator, which will help prevent mold, fungus, and bacteria from growing.


 Change dirty cabin air filters

Air conditioning systems trap tiny particles that settle in the filters over time and cause mildew growth when exposed to moisture. If your air conditioner's filter is dirty and clogged, this may encourage the development of a musty smell in your AC.


Clogged evaporator drain

The evaporator drain helps in removing the condensation generated by the evaporator coils. A clogged drain can trap excess moisture and promote the growth of mildew around the coil and cause your air conditioner to smell musty.
