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 impact your home comfort.
Where do bad AC smells come from?
Begin with what the odor smells like. If the odor resembles a rotten egg, this could be a sign 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. 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 issue.
Just like anything in your indoor space, if your air conditioner isn’t cleaned properly or taken care of, there’s a good chance that dirt and dust will develop. 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 occur with the coils, drain pain, air ducts or even your filter. Thankfully, regular maintenance can help prevent this buildup and reduce the chances that an unfriendly smell starts spreading throughout your house.
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 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 retrieve the animal.
What can I do?
Assess your filter. This is a common culprit for air conditioner odors. If it’s been a long time since you’ve swapped your air filter, try replacing it with a brand new one. We typically advise changing your filter every few months. But it’s also important to keep in mind other reasons that would require you to replace it more repeatedly, 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 lengthy period of time since your last air conditioning inspection. The pros can examine 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 benefit from a proper cleaning.
