When your air conditioner starts emitting strange or funky odors, it is necessary to take notice because it could be a sign of a significant problem. Disregarding unpleasant smells coming from your cooling system could lead to serious damage to your air conditioning or even pose a risk to your health and safety.
Depending on the cause of the odor, the culprit could be bacteria or fungus in the system. In other cases, it could also signal something mechanically wrong with the air conditioner. Some smells are even indicative of an unsafe situation, like a natural gas leak.

What does a particular smell billowing from your cooling system mean? Here are a few typical air conditioner odors and what they may mean:
My Air Conditioner Smells Like Feet
If your air conditioner smells like feet, it can be due to a buildup of bacteria or fungus inside of it. When moisture collects inside the unit, it can establish an environment that is conducive to the spread of bacteria and fungus. This can produce a nasty odor that is often described as smelling like dirty feet.
Another possible explanation for an odor of stinky feet could be a dirty air filter. When your HVAC system's air filter becomes clogged with dirt, dust and other debris, it can lead to poor air quality and a musty smell that resembles feet.
To solve this dilemma, it's important to have a professional inspect and clean your air conditioning system, including the evaporator coil, drain pan and condensate drain line. It's also important to exchange the air filter on a regular basis to provide good air quality and restrict the growth of bacteria and fungus.
My Air Conditioner Smells Like Rotten Eggs
If your air conditioner reeks of rotten eggs, it could be the result of a natural gas leak in the unit or in the surrounding area. Natural gas has a unique odor, often described as smelling like rotten eggs or sulfur, which is because of a substance added to it to make it easily detectable.
A natural gas leak is very dangerous and requires immediate attention. If you suspect a gas leak, turn off your air conditioning system, immediately open windows and doors to air out the area, make everyone leave the building and call your gas company or emergency services right away.
My Air Conditioner Smells Like Mildew
If your cooling system is giving off an odor like mildew, it might be due to a accumulation of moisture inside the unit. When moisture collects inside a cooling system, it can cultivate the growth of mold and mildew. This can cause a musty stench that bears a resemblance to mildew.
Another possible explanation for the smell could be a clogged air filter. Once the air filter becomes clogged, it can result in poor air quality and a musty smell that resembles mildew.
Regular air conditioning maintenance from Air Temperature Control can help prevent both of these situations, because a good cleaning, inspection and filter change is a terrific way to keep your system working at its best!
My Air Conditioner Smells Like Urine
One of the most distressing scenarios is when your AC smells like urine.
If your air conditioning equipment reeks of urine, it could be traced back to a number of things. One possible cause is a buildup of bacteria or mold in the your cooling system. This can happen when moisture accumulates in the system and creates a wet environment that can promote bacterial growth. The bacteria can create a foul odor that some people describe as smelling like urine.
Another potential cause of the smell could be a blocked drain line. The condensation that forms inside the air conditioning unit needs to drain away properly, but if the drain line becomes filled with debris, it can cause water to back up and build up inside the unit. This can generate a musty smell that can stink like urine.
My Air Conditioner Smells Like Burning Plastic
If your air conditioner smells like burning plastic, a possible cause could be an electrical issue with the unit. After some time, the electrical elements in the air conditioning system can wear out or bust, which can create a burning smell that resembles plastic.
Another possible cause of the smell could be a foreign object stuck in the unit. If something foreign gets trapped in the air conditioning system, it can heat up and result in a smell like burning plastic.
If you smell burning plastic coming from your cooling system, it’s important to call a professional right away.
My Air Conditioner Smells Like Gas
If your air conditioner smells like gas, there could be a natural gas leak in the unit or in the surrounding area. Natural gas has a recognizable odor, often described as smelling similar to rotten eggs or sulfur. That’s because an odor is incorporated into natural gas so that it is easily detectable.
As we said before, a natural gas leak can be VERY hazardous and calls for immediate attention. Should you suspect a gas leak, turn off your air conditioning system, open windows and doors to air out the home, get everyone out of the building and phone your gas company or emergency services as soon as possible.
Why My Air Conditioner Smells Like Fish
When your air conditioning equipment smell like fish, this could be a sign of a build-up of bacteria or mold in the unit. Moisture creates an environment that fosters the growth of bacteria and mold. This can cause a foul odor that can be described as smelling like fish or, as mentioned earlier, it also can cause a smell like dirty feet.
Another potential cause of the smell could be a dead animal or other biological material caught in the air conditioning system. This often can happen if an animal such as a mouse or bird becomes trapped inside the unit and dies.
To fix the issue, it's important to have a professional check out and clean your air conditioning system. They can identify the source of the smell and take the correct steps to remove any contaminants and prevent the problem from recurring.
Why My Air Conditioner Smells Like Vinegar
There could be numerous reasons a home's air conditioner smells like vinegar. One possible cause might be a clogged air filter. One other likely cause of the smell might be a refrigerant leak. If the refrigerant leaks, it can make a chemical odor that resembles vinegar.
To fix the issue, it's beneficial to have a skilled mechanic examine and clean your air conditioning. If the odor continues after the cleaning and exchanging the air filter, it's best to reach back out to a professional to identify and repair any persistent issues with your air conditioning. Or, the tech can tell you if your air conditioning needs to be replaced.
If you are planning to upgrade, Air Temperature Control can help locate the correct unit to fit your home’s needs. We provide dependable, expert air conditioner installation in Macon.
My Air Conditioner Smells Like Chemicals
If the smell of chemicals is emitting out of your air conditioner, it could be the result of a refrigerant leak. When the refrigerant leaks, it can create a chemical scent that people sometimes describe as smelling like chemicals or paint thinner, vinegar or acetone.
Another possible cause of the smell could be problems with the electrical wiring or hardware inside the air conditioning system. This can result in a burning smell that resembles chemicals or burning plastic.
If you believe there is a refrigerant leak or an electrical concern, it's important to shut down your air conditioning system as soon as possible and contact a professional to inspect and repair the unit. Refrigerant leaks can be harmful and may require immediate attention to prevent injury or damage to your residence.
