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 observe 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 signal of a gas leak. If this is the case, you should open your windows, turn off the gas supply, evacuate the home and call 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 have a different problem.

Just like anything in your indoor space, if your air conditioner isn’t cleaned correctly or taken care of, there’s a good chance that dirt and dust will gather. 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 most common sources of odors with air conditioners. It can take place with the coils, drain pain, air ducts or even your filter. Luckily, ongoing maintenance can help decrease this buildup and reduce the probability that an unfriendly smell starts dispersing throughout your house.

Heat and moisture can contribute to increased mold growth, specially 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 home.

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 remove 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 changed your air filter, try replacing it with a brand new one. We typically recommend changing your filter every two to three months. But it’s also vital to keep in mind other factors 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 helping, it’s probably time to reach out for some help. Especially if it’s been an lengthy period of time since your last air conditioning checkup. They can examine the situation to see if a thorough cleaning can do the job. You might 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.
