Woman wondering why her AC is acting up

Why does it smell bad when my air conditioner runs?

We 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 impact your home comfort.

Where do the smells come from?

Focus on what the odor smells like. If the odor resembles a rotten egg, this could be a signal 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 tackle yourself.

If it doesn’t smell like rotten eggs, you are likely experiencing a different challenge.

Just like anything in your indoor space, if your air conditioner isn’t cleaned properly 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 most request 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 probability that an unfriendly smell starts diffusing throughout your home.

Heat and moisture can contribute to increased mold growth, particularly 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 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.

What can I do?

Check 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, go ahead and replace it with a brand new one. We typically suggest changing your filter every two to three months. But it’s also key to keep in mind other elements that would require you to replace it more repeatedly, 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 reach out for some help. Especially if it’s been an extended period of time since your last air conditioning checkup. Technicians can assess 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 benefit from a proper cleaning.
