Woman wondering why her AC is acting up

Why does it smell bad when my air conditioner runs?

Many 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 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 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 reach out to the gas company. Allow the gas company turn it back on for you. It’s not something you want to tackle yourself.

If it doesn’t smell like rotten eggs, you probably 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 develop. 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 take place with the coils, drain pain, air ducts or even your filter. However, regular maintenance can help avoid this buildup and reduce the odds that an unfriendly smell starts diffusing throughout your home.

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

What can I do?

Analyze your filter. This is a usual culprit for air conditioner odors. If it’s been a long time since you’ve swapped your air filter, go ahead and replace it with a brand new one. We typically suggest changing your filter every three months. But it’s also key 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 replaced 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. The pros 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.
