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

Where are these smells coming from?

Begin 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 have a different issue.

Just like anything in your house, 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 occur with the coils, drain pain, air ducts or even your filter. However, routine maintenance can help prevent this buildup and reduce the odds that an unfriendly smell starts diffusing throughout your house.

Heat and moisture can contribute to increased mold growth, especially 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 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 get the animal.

Where do I start?

Assess your filter. This is a usual 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 advise changing your filter every few months. But it’s also vital to keep in mind other elements 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 reducing the smell, it’s probably time to contact a professional. Especially if it’s been an lengthy period of time since your last air conditioning checkup. The pros can assess 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.
