The majority of us install air conditioners to help us feel relaxed in our homes. But when you start to observe unpleasant odors coming from your cooling system, it’s more than just bothersome. It can greatly impact your home comfort.

Where are these smells coming from?

Start with 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 contact the gas company. Be sure to have 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 challenge.

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 develop. 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 most frequent reasons you’ll notice odors with air conditioners. It can occur with the coils, drain pain, air ducts or even your filter. Luckily, routine maintenance can help prevent this buildup and reduce the chances that an unfriendly smell starts diffusing throughout your house.

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 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 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 two to three months. But it’s also important to keep in mind other reasons 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 replaced the filter and it’s not reducing the smell, 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 inspection. Technicians can review 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 improve from a proper cleaning.
