We 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 affect your home comfort.

Where do the smells come 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 risk doing on your own.

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 correctly or taken care of, there’s a good chance that dirt and dust will develop. 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 more typical culprits of odor with air conditioners. It can take place with the coils, drain pain, air ducts or even your filter. Luckily, regular maintenance can help avoid this buildup and reduce the chances that an unfriendly smell starts dispersing throughout your space.

Heat and moisture can contribute to increased mold growth, particularly 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 space.

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 should you do?

Assess your filter. This is a typical culprit for air conditioner odors. If it’s been a long time since you’ve exchanged your air filter, replace it with a brand new one. We typically recommend changing your filter every three months. But it’s also key to keep in mind other reasons that would require you to replace it more frequently, 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 examination. Technicians can review 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 improve from a proper cleaning.
