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

Where do bad AC 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 reach out to the gas company. Make sure to let 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 are likely experiencing a different problem.

Just like anything in your indoor space, if your air conditioner isn’t cleaned well 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 more typical culprits of odor with air conditioners. It can happen with the coils, drain pain, air ducts or even your filter. However, routine maintenance can help decrease this buildup and reduce the odds that an unfriendly smell starts diffusing throughout your house.

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 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.

What should you do?

Assess your filter. This is a common culprit for air conditioner odors. If it’s been a long time since you’ve swapped your air filter, try replacing 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 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 helping, it’s probably time to contact a professional. Especially if it’s been an extended period of time since your last air conditioning checkup. They 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 improve from a proper cleaning.
