Woman wondering why her AC is acting up

Why does it smell bad when my air conditioner runs?

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 irritating. It can greatly influence 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 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. Allow 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 are likely experiencing a different issue.

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 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. Luckily, ongoing maintenance can help avoid this buildup and reduce the chances 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 create a nasty smell, but it can also negatively impact the quality of air in your house.

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.

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 swapped your air filter, try replacing it with a brand new one. We typically recommend changing your filter every three months. But it’s also vital to keep in mind other elements 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 helping, it’s probably time to call in an expert. Especially if it’s been an lengthy period of time since your last air conditioning examination. 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 be enhanced from a proper cleaning.
