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

Where are these smells coming from?

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

If it doesn’t smell like rotten eggs, you probably have a different issue.

Just like anything in your house, if your air conditioner isn’t cleaned properly or taken care of, there’s a good chance that dirt and dust will accumulate. And because components of your air conditioner aren’t front and center, 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 happen with the coils, drain pain, air ducts or even your filter. Thankfully, ongoing maintenance can help prevent this buildup and reduce the probability that an unfriendly smell starts dispersing throughout your space.

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

It’s also possible that a small animal 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 swapped your air filter, replace it with a brand new one. We typically recommend changing your filter every two to three months. But it’s also important to keep in mind other elements 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 call in an expert. Especially if it’s been an extended period of time since your last air conditioning inspection. The pros can examine the situation to see if a thorough cleaning can do the job. You may also want to 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.
