Woman wondering why her AC is acting up

Why does it smell bad when my air conditioner runs?

Many of us install air conditioners to help us feel comfortable in our homes. But when you start to observe unpleasant odors coming from your cooling system, it’s more than just irritating. It can greatly affect your home comfort.

Where do the smells come from?

Start 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 mess around with.

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 correctly 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 common sources of odors with air conditioners. It can happen with the coils, drain pain, air ducts or even your filter. Luckily, routine 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, 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 house.

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 get the animal.

What can I do?

Check your filter. This is a typical 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 suggest changing your filter every three months. But it’s also important to keep in mind other elements 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 making a difference, it’s probably time to reach out for some help. Especially if it’s been an extended period of time since your last air conditioning examination. 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 benefit from a proper cleaning.

You should be able to enjoy your cool indoor space throughout the warmer summer months, without having to suffer with unfavorable odors.
