We install air conditioners to help us feel cool 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?

Focus on 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. Make sure to let 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 problem.

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 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 more typical culprits of odor with air conditioners. It can take place with the coils, drain pain, air ducts or even your filter. Luckily, regular maintenance can help avoid this buildup and reduce the odds that an unfriendly smell starts spreading throughout your house.

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

Analyze your filter. This is a typical culprit for air conditioner odors. If it’s been a long time since you’ve exchanged your air filter, replace it with a brand new one. We typically recommend changing your filter every three months. But it’s also key to keep in mind other reasons 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 switched 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 long period of time since your last air conditioning examination. 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.
