We install air conditioners to help us feel cool in our homes. But when you start to experience unpleasant odors coming from your cooling system, it’s more than just bothersome. 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 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. Make sure to let the gas company turn it back on for you. It’s not something you want to mess around with.

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 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 clearly displayed before you, cleaning them can often go overlooked.

Buildup of mold, dirt and other particles is one of the most frequent reasons you’ll notice odors with air conditioners. It can take place with the coils, drain pain, air ducts or even your filter. However, ongoing maintenance can help decrease this buildup and reduce the odds that an unfriendly smell starts dispersing throughout your space.

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

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 remove the animal.

What should you do?

Check your filter. This is a common culprit for air conditioner odors. If it’s been a long time since you’ve exchanged 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 switched the filter and it’s not helping, it’s probably time to reach out for some help. Especially if it’s been an long period of time since your last air conditioning examination. The pros can review 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 improve from a proper cleaning.
