The majority of us 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 annoying. It can greatly impact 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 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. Make sure to let 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 have a different problem.

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 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 happen with the coils, drain pain, air ducts or even your filter. Luckily, routine maintenance can help prevent this buildup and reduce the odds that an unfriendly smell starts spreading throughout your space.

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

It’s also possible that a little critter 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.

Where do I start?

Analyze 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 often, 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 reducing the smell, 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. 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 be enhanced from a proper cleaning.
