Why Your Air Conditioner Smells And How To Fix It?
When your air conditioner starts putting out odd or gross odors, it is a good idea to take notice because it could be a sign of a major problem. Disregarding unpleasant smells coming from your cooling system can lead to serious damage to your air conditioning or even pose a risk to your health and safety.
Depending on the smell, the cause may be bacteria or fungus in the system. Other times, it could also signal something mechanically wrong with the AC. Some smells are even indicative of a dangerous situation, including a natural gas leak.

What does a specific odor wafting from your air conditioning mean? Here are a few common air conditioner aromas and what they may mean:
My Air Conditioner Smells Like Feet
If your air conditioner smells like feet, it could be caused by a buildup of bacteria or fungus in the system. When moisture collects inside the unit, it can create an environment that is beneficial to the development of bacteria and fungus. This can cause a bad odor that is often described as smelling like feet.
Another likely reason for the smell may be a dirty air filter. When your HVAC system’s air filter becomes filled with dirt, dust and other debris, it can lead to poor air quality and a musty smell that bears a resemblance to 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 replace the air filter on a regular basis to provide good air quality and protect against the growth of bacteria and fungus.
My Air Conditioner Smells Like Rotten Eggs
If your air conditioning equipment stinks like rotten eggs, it might 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, that is added to it to make it easily detectable.
A natural gas leak can be very dangerous and requires immediate attention. If you suspect a gas leak, turn off your air conditioning system, immediately open windows and doors to allow gas to escape the area, evacuate the building and call your gas company or emergency services at once.
Your AC Smells Like Mildew
If your cooling system emits a smell like mildew, it may 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 odor that resembles mildew.
Another possible cause of the smell may be a soiled air filter. Once the air filter becomes clogged, it can result in poor air quality and a musty smell that resembles mildew.
Routine air conditioning maintenance from Tokay Heating & Air can help prevent both of these situations, because a good cleaning, inspection and filter change is a terrific way to keep your system running at its best!
The Air Conditioning Smells Like Urine
One of the most distressing things is when your AC smells like urine.
If your air conditioning equipment stinks like urine, it could could be caused by multiple factors. One possible cause is a collection of bacteria or mold in the air conditioning system. This can happen in the event that moisture accumulates in the system and creates a damp environment that is conducive to bacterial growth. The bacteria can produce a foul odor that is like urine.
Another feasible cause of the scent of urine could be a clogged drain line. The condensation that forms inside the air conditioning unit needs to drain away properly, but if the drain line becomes stopped up by 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 conditioning unit smells like burning plastic, this could indicate an electrical problem with the unit. After some time, the electrical elements in the air conditioning system can wear out or bust, which can produce a burning smell that resembles plastic.
Another possible cause of the smell could be a foreign object stuck in the the air conditioner. If something foreign gets caught in the air conditioning system, it can become hot and cause a smell that reminds people of burning plastic.
If you smell burning plastic coming from your air conditioner, it’s worthwhile to contact a professional right away.
Your AC Smells Like Gas
If your AC smells like gas, it could be because of a natural gas leak in the unit or in the surrounding area. Natural gas has a distinct smell, often described as smelling similar to rotten eggs or sulfur. That’s because a smell is added to natural gas so that it is easily detectable.
As mentioned earlier, a natural gas leak can be VERY hazardous and needs 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 contact your gas company or emergency services right away.
The Air Conditioning Smells Like Fish
When your air conditioner smell like fish, it could be due to a build-up of bacteria or mold in the unit. Moisture causes an environment that fosters the growth of bacteria and mold. This can cause a foul odor that is often described as smelling like fish or, as mentioned earlier, it also can create a smell like dirty feet.
Another possible cause of the smell could be a dead animal or other biological material caught in the air conditioning system. This often can take place if an animal such as a mouse or bird gets trapped inside the unit and dies.
To solve the issue, it’s often necessary to have a professional examine and clean your cooling system. They should be able to find the source of the smell and take the correct steps to remove any contaminants and stop the problem from recurring.
The Air Conditioning Smells Like Vinegar
There could be several reasons an air conditioner smells like vinegar. One possible cause of the smell could be a dirty 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 important to have a skilled mechanic examine and clean your air conditioning. If the odor persists after the cleaning and exchanging the air filter, it’s best to reach back out to a professional to identify and repair any hidden issues with your air conditioning. Or, the mechanic can tell you if your air conditioning should be replaced.

Your AC Smells Like Chemicals
If the smell of chemicals is emitting out of your air conditioning unit, it could be caused by a refrigerant leak. If the refrigerant leaks, it can create a chemical scent that some people describe as smelling like chemicals or paint thinner, vinegar or acetone.
One other possible reason for the smell could be problems with the electrical wiring or components inside the air conditioning system. This can result in a burning smell that resembles chemicals or burning plastic.
If you suspect a refrigerant leak or an electrical concern, it’s important to shut down your air conditioning system right away and contact a professional to inspect and repair the unit. Refrigerant leaks can be hazardous and may require immediate attention to avoid injury or damage to your home.
