Many of us 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 irritating. It can greatly influence 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 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. 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 are likely experiencing a different problem.

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

Buildup of mold, dirt and other particles is one of the more typical culprits of odor with air conditioners. It can take place with the coils, drain pain, air ducts or even your filter. Thankfully, routine maintenance can help decrease this buildup and reduce the chances that an unfriendly smell starts diffusing throughout your house.

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 should you do?

Check 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 three months. But it’s also vital to keep in mind other reasons 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 helping, 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 examine the situation to see if a thorough cleaning can do the job. You might 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.
