We install air conditioners to help us feel cool in our homes. But when you start to observe 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?

Start with 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 call the gas company. Allow 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 have a different issue.

Just like anything in your home, 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 happen with the coils, drain pain, air ducts or even your filter. Luckily, ongoing maintenance can help avoid this buildup and reduce the chances that an unfriendly smell starts dispersing throughout your house.

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 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 get the animal.

Where do I start?

Assess 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, replace it with a brand new one. We typically recommend changing your filter every few months. But it’s also vital 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 exchanged the filter and it’s not making a difference, it’s probably time to call in an expert. Especially if it’s been an long period of time since your last air conditioning checkup. 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 be enhanced from a proper cleaning.
