The majority of us 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 annoying. It can greatly affect your home comfort.

Where do the smells come from?

Begin 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 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 have a different problem.

Just like anything in your home, if your air conditioner isn’t cleaned well or taken care of, there’s a good chance that dirt and dust will gather. 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 common sources of odors with air conditioners. It can occur with the coils, drain pain, air ducts or even your filter. However, regular maintenance can help avoid this buildup and reduce the chances that an unfriendly smell starts spreading throughout your home.

Heat and moisture can contribute to increased mold growth, particularly in warmer climates. Not only can mold and mildew create 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.

What can I do?

Assess your filter. This is a typical culprit for air conditioner odors. If it’s been a long time since you’ve changed your air filter, go ahead and replace it with a brand new one. We typically advise 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 making a difference, it’s probably time to reach out for some help. Especially if it’s been an lengthy period of time since your last air conditioning examination. They can examine 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 be enhanced from a proper cleaning.
