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 annoying. It can greatly impact your home comfort.

Where are these smells coming from?

Begin with what the odor smells like. If the odor resembles a rotten egg, this could be an indication of a gas leak. If this is the case, you should open your windows, turn off the gas supply, evacuate the home and contact 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 are likely experiencing a different challenge.

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 right in front of 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 occur with the coils, drain pain, air ducts or even your filter. Thankfully, routine maintenance can help decrease this buildup and reduce the probability that an unfriendly smell starts diffusing throughout your house.

Heat and moisture can contribute to increased mold growth, particularly 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 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 get the animal.

Where do I start?

Check your filter. This is a usual 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 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 reach out for some help. Especially if it’s been an long period of time since your last air conditioning checkup. The pros 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 be enhanced from a proper cleaning.
