How Do I Get Rid of the Smell in My Air Conditioner?


A smelly air conditioner is more than just a frustration. Depending on the source of the smell, it can indicate a problem that’s hurting your indoor air quality. Therefore, it is important to address the musty smell and deal with the underlying issue for the sake of your comfort and safety. Here is how you can do it.

Identifying the Smell

First, identify the location of the smell. Some common reasons that you might be having a problem with mildew in your indoor air quality include:

  • Mold and mildew growth – If you have water clogging up somewhere inside your air conditioner, it can allow mold and mildew to grow, which can cause a musty smell.

  • Clogged drain lines – One factor that can allow mold and mildew growth is a clogged drain line.

  • Clogged filters – Filters can collect mildew and mold, and if they are not changed on time, you will smell it.

  • A dead animal – If a dead animal takes up residents in your air ducts and dies, you will smell rotten eggs.

  • Gas leak – A gas leak in your system will smell like a skunk or eggs. If you notice this smell, don’t wait to call in an expert — this is an emergency.

  • Motor shorting out – A burning smell or gun powder smell indicates the air conditioner has short-circuited.

Addressing the Problem

The most common reason for an air conditioner to develop a smell is mold and mildew growth. To deal with this problem, you must first repair the cause. Drain line and filter clogs are most common, so have an HVAC professional address this issue for you. Then, once the clog and moisture are removed, consider professional duct cleaning to remove the actual mildew. This two-step process will get rid of the smell.

If you have a dead animal or similar debris in your system, you will need to schedule a professional cleaning. Professional removal of the problem and cleaning the system is the only way to address this issue effectively.

For a motor that has shorted out, you need professional HVAC repair. Air Experts has a team standing by who can repair or replace the motor on your AC unit so that you can enjoy a cool home without any unwanted smells or risks.

Gas smells indicate a true emergency. If you smell gas, leave the home and call 911 and your gas provider. Emergency responders will be able to test the home for gas and remove it. After it is safe, give Air Experts a call to repair the leak and get you back in your home. Do not stay in a home and try to find the source of the leak yourself.
