Prevent Your Porsche’s AC from Smelling like Mildew
By Bavarian Performance Specialists May 25, 2023
As a Porsche owner, you want your car to look and smell great at all times. However, over time, the air conditioning system in your Porsche can develop an unpleasant odor, which is often described as a musty or mildew smell. This can be caused by a variety of factors, including a dirty cabin air filter, moisture buildup, or bacteria growth in the AC system.
An air conditioning (AC) system in a car consists of several parts that work together to provide cool air to the cabin. The compressor is the heart of the AC system, responsible for compressing and circulating the refrigerant, which is the substance that absorbs heat from the air in the cabin. The condenser is located in front of the car’s radiator and is responsible for releasing the heat absorbed by the refrigerant in the compressor to the outside air. The accumulator stores the refrigerant and removes any moisture or contaminants in the refrigerant. The evaporator absorbs the heat from the air in the cabin as the refrigerant flows through it, and the cooled air is then blown into the cabin by the blower motor.
If mildew begins growing inside this system, it can result in an unpleasant and unhealthy odor in your Porsche. Let’s look closer at how to circumvent this.
Change Your Cabin Air Filter Regularly
The cabin air filter in your Porsche’s AC system is designed to remove dust, pollen, and other airborne particles from the air that enters the cabin. Over time, the filter can become clogged with dirt and debris, which can cause moisture buildup and bacteria growth, resulting in a musty odor. To prevent this, it is recommended that you replace your cabin air filter every 15,000 miles or once a year, whichever comes first.
Run Your AC System Regularly
Moisture buildup in your Porsche’s AC system can also contribute to a mildew smell. This is because when your AC is not in use, condensation can accumulate in the evaporator, which can create a damp environment for bacteria and mold to grow. To prevent this, it is recommended that you run your AC system at least once a week, even during the winter months, to help circulate air and reduce moisture buildup.
Keep Your Porsche Clean and Dry
Another way to prevent your Porsche’s AC from smelling like mildew is to keep your car clean and dry. Moisture from wet shoes, clothing, or even pets can contribute to moisture buildup in your AC system. Therefore, it is important to dry any wet items before placing them in your car and to clean up any spills or moisture as soon as possible. Additionally, it is recommended that you park your car in a garage or covered area to reduce exposure to moisture from rain or snow.
Use an AC System Cleaner
Using an AC system cleaner can help eliminate bacteria and mold growth in your Porsche’s AC system, which can prevent the development of a mildew smell. These cleaners are typically applied through the air intake or through a special tool that is inserted into the AC system. It is important to follow the instructions on the cleaner carefully and to ensure that the AC system is running when applying the cleaner.
Have Your AC System Serviced Regularly
Regular servicing of your Porsche’s AC system can help prevent the development of a mildew smell. During a service, the AC system is inspected for any leaks or damage, the refrigerant level is checked, and the system is cleaned and deodorized. It is recommended that you have your AC system serviced every 2-3 years or as recommended by your Porsche’s owner manual.
