The majority of us install air conditioners to help us feel comfortable in our homes. But when you start to experience unpleasant odors coming from your cooling system, it’s more than just irritating. It can greatly affect 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 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 are likely experiencing a different challenge.

Just like anything in your home, if your air conditioner isn’t cleaned properly or taken care of, there’s a good chance that dirt and dust will accumulate. 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 most common sources of odors with air conditioners. It can occur with the coils, drain pain, air ducts or even your filter. Thankfully, regular maintenance can help prevent this buildup and reduce the probability that an unfriendly smell starts diffusing throughout your space.

Heat and moisture can contribute to increased mold growth, especially 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 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 should you do?

Assess 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, try replacing it with a brand new one. We typically suggest changing your filter every two to three months. But it’s also vital to keep in mind other elements that would require you to replace it more frequently, 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 call in an expert. Especially if it’s been an long 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 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 benefit from a proper cleaning.
