We 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 annoying. It can greatly influence your home comfort.

Where do the smells come 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. Be sure to have the gas company turn it back on for you. It’s not something you want to mess around with.

If it doesn’t smell like rotten eggs, you have a different problem.

Just like anything in your house, if your air conditioner isn’t cleaned correctly or taken care of, there’s a good chance that dirt and dust will accumulate. And because components of your air conditioner aren’t front and center, 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 happen with the coils, drain pain, air ducts or even your filter. Luckily, regular maintenance can help prevent this buildup and reduce the probability that an unfriendly smell starts dispersing throughout your space.

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

What can I do?

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, go ahead and 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 reasons 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 exchanged the filter and it’s not making a difference, it’s probably time to contact a professional. Especially if it’s been an long period of time since your last air conditioning examination. Technicians 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 improve from a proper cleaning.
