We install air conditioners to help us feel comfortable 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 influence your home comfort.

Where are these smells coming 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 call the gas company. Allow 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 are likely experiencing a different challenge.

Just like anything in your indoor space, if your air conditioner isn’t cleaned well or taken care of, there’s a good chance that dirt and dust will gather. 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 frequent reasons you’ll notice odors with air conditioners. It can happen with the coils, drain pain, air ducts or even your filter. Thankfully, ongoing maintenance can help avoid this buildup and reduce the chances that an unfriendly smell starts dispersing throughout your space.

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 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 get the animal.

Where do I start?

Assess your filter. This is a common culprit for air conditioner odors. If it’s been a long time since you’ve changed your air filter, replace it with a brand new one. We typically advise changing your filter every three months. But it’s also vital 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 switched the filter and it’s not helping, it’s probably time to contact a professional. Especially if it’s been an lengthy period of time since your last air conditioning checkup. The pros 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 benefit from a proper cleaning.
