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 relaxed 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 impact 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. 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 correctly or taken care of, there’s a good chance that dirt and dust will accumulate. And because components of your air conditioner aren’t front and center, 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 occur with the coils, drain pain, air ducts or even your filter. Luckily, routine maintenance can help avoid this buildup and reduce the odds that an unfriendly smell starts spreading throughout your home.

Heat and moisture can contribute to increased mold growth, especially in warmer climates. Not only can mold and mildew induce 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 can I do?

Check 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, replace it with a brand new one. We typically suggest changing your filter every few months. But it’s also important to keep in mind other factors 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 exchanged the filter and it’s not making a difference, it’s probably time to contact a professional. Especially if it’s been an extended period of time since your last air conditioning examination. Technicians 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 improve from a proper cleaning.
