We install air conditioners to help us feel cool in our homes. But when you start to notice unpleasant odors coming from your cooling system, it’s more than just bothersome. 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 signal 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. Allow 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 have a different problem.

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 gather. 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. However, regular maintenance can help decrease this buildup and reduce the chances that an unfriendly smell starts spreading throughout your house.

Heat and moisture can contribute to increased mold growth, particularly 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 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 remove the animal.

What can I do?

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

If you’ve exchanged 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 checkup. They can assess 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 benefit from a proper cleaning.
