Woman wondering why her AC is acting up

Why does it smell bad when my air conditioner runs?

We 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 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 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 risk doing on your own.

If it doesn’t smell like rotten eggs, you are likely experiencing a different challenge.

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 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 happen with the coils, drain pain, air ducts or even your filter. Thankfully, ongoing maintenance can help decrease this buildup and reduce the chances that an unfriendly smell starts dispersing throughout your home.

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 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?

Analyze 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, try replacing it with a brand new one. We typically suggest changing your filter every three months. But it’s also key to keep in mind other elements 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 making a difference, it’s probably time to call in an expert. Especially if it’s been an extended period of time since your last air conditioning examination. The pros 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.

If you have frustrations about the odors in your home, Central Aire Heating & A/C Inc can help you take a look at the situation and talk through possible solutions. You should be able to enjoy your cool indoor space during the warmer summer months, without having to suffer with undesirable odors.
