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 irritating. It can greatly influence 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 call the gas company. Be sure to have the gas company turn it back on for you. It’s not something you want to tackle yourself.
If it doesn’t smell like rotten eggs, you are likely experiencing a different problem.
Just like anything in your house, 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 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 occur with the coils, drain pain, air ducts or even your filter. Thankfully, ongoing maintenance can help avoid this buildup and reduce the probability that an unfriendly smell starts spreading throughout your house.
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 small animal 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.
What should you do?
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, try replacing it with a brand new one. We typically advise changing your filter every two to three months. But it’s also important 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 replaced the filter and it’s not reducing the smell, it’s probably time to contact a professional. Especially if it’s been an extended period of time since your last air conditioning inspection. They can review 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 improve from a proper cleaning.
