The majority of us 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 annoying. It can greatly affect 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 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. Make sure to let 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 probably have a different challenge.

Just like anything in your house, if your air conditioner isn’t cleaned well 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 more typical culprits of odor with air conditioners. It can occur with the coils, drain pain, air ducts or even your filter. However, ongoing maintenance can help avoid this buildup and reduce the odds that an unfriendly smell starts dispersing throughout your space.

Heat and moisture can contribute to increased mold growth, particularly 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 house.

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.

Where do I start?

Assess 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, go ahead and replace it with a brand new one. We typically recommend changing your filter every two to three months. But it’s also key to keep in mind other factors 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 helping, it’s probably time to contact a professional. Especially if it’s been an long period of time since your last air conditioning checkup. Technicians can examine 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 improve from a proper cleaning.
