We install air conditioners to help us feel relaxed in our homes. But when you start to notice unpleasant odors coming from your cooling system, it’s more than just annoying. It can greatly affect your home comfort.

Where do bad AC smells come from?

Focus on what the odor smells like. If the odor resembles a rotten egg, this could be an indication of a gas leak. If this is the case, you should open your windows, turn off the gas supply, evacuate the home and reach out to the gas company. Be sure to have the gas company turn it back on for you. It’s not something you want to tackle yourself.

If it doesn’t smell like rotten eggs, you are likely experiencing a different challenge.

Just like anything in your home, if your air conditioner isn’t cleaned correctly or taken care of, there’s a good chance that dirt and dust will develop. And because components of your air conditioner aren’t clearly displayed before you, cleaning them can often go overlooked.

Buildup of mold, dirt and other particles is one of the most common sources of odors with air conditioners. It can take place with the coils, drain pain, air ducts or even your filter. Thankfully, regular maintenance can help avoid this buildup and reduce the chances that an unfriendly smell starts dispersing throughout your space.

Heat and moisture can contribute to increased mold growth, particularly in warmer climates. Not only can mold and mildew create a nasty smell, but it can also negatively impact the quality of air in your home.

It’s also possible that a tiny creature navigated into your duct system and died. You can turn off your air conditioner and either give our team or pest control a call to come and retrieve the animal.

What can I do?

Check your filter. This is a usual culprit for air conditioner odors. If it’s been a long time since you’ve changed your air filter, try replacing it with a brand new one. We typically recommend changing your filter every few months. But it’s also key to keep in mind other factors that would require you to replace it more repeatedly, such as pets in the home or if a family member has allergies or asthma.

If you’ve replaced the filter and it’s not reducing the smell, it’s probably time to contact a professional. Especially if it’s been an lengthy period of time since your last air conditioning inspection. They can review the situation to see if a thorough cleaning can do the job. You could consider having your air ducts cleaned. Professional duct cleaners can take a look to see if your indoor air quality would be enhanced from a proper cleaning.
