Why Does My Window AC Smell Bad and How to Solve It?
Why Does My Window AC Smell?
If your window AC smells, it could be due to water buildup in the unit.
This can lead to mold and mildew growth if not drained properly.
Some window air conditioners may not have an easy way to drain the water, unlike July, a new window AC model with a drain plug.
If there is no drain hole, gently tipping the AC on its back can help the water flow out.
Additionally, checking and cleaning or replacing the air filter can address musty, moldy odors emitted by the air conditioner.
However, if the odor has a chemical smell, it may indicate a refrigerant leakage, which requires immediate discontinuation of use.
If within the warranty period, contacting the manufacturer for a replacement is advised, as refrigerant leaks cannot be repaired.
Key Points:
- Window AC smells may be caused by water buildup in the unit
- Mold and mildew growth can occur if the water is not drained properly
- Some window AC models, like July, have a drain plug for easy water drainage
- If there is no drain hole, tipping the AC on its back can help the water flow out
- Cleaning or replacing the air filter can help eliminate musty, moldy odors from the AC
- Chemical smells may indicate a refrigerant leakage, requiring immediate discontinuation of use and contacting the manufacturer for a replacement
Did You Know?
1. Some window AC units may give off a foul odor due to the growth of mold and bacteria on the unit’s evaporator coil, which can create a musty smell in your room.
2. To prevent unpleasant smells, it is recommended to clean or replace the window AC unit’s filters regularly, as they can accumulate dirt and debris that contribute to odors.
3. Certain strong odors, such as cigarette smoke or cooking smells, can get trapped in the window AC unit’s filters and be recirculated into your room, intensifying their presence.
4. In some cases, decomposing leaves or other organic materials can find their way into the window AC unit, causing a strange smell when the unit is turned on.
5. If the window AC unit smells like chemicals or burning, it could indicate a malfunction or an electrical issue that requires immediate attention from a professional technician.
Water Buildup: Common Cause Of Smelly Window Acs
Having a window air conditioner can be a lifesaver during those scorching summer months, but what happens when a strange odor starts wafting from the unit? One common cause of bad smells in window air conditioners is water buildup.
When the unit operates, it naturally produces condensation, which is usually directed outside through a drain hole. However, if this drain hole becomes blocked or the unit doesn’t have one at all, the water can start to accumulate inside. This standing water can become a breeding ground for mold and mildew, leading to unpleasant odors emanating from the unit.
To address this issue, here are some helpful tips:
- Clean the drainage system: Check if the drain hole is clear and not clogged with debris. Clean it regularly to prevent water buildup.
- Use a deodorizer: Consider using an air conditioner deodorizer specifically designed to eliminate odors caused by mold and mildew.
- Ensure proper ventilation: Allow fresh air to circulate in the room by opening windows or using a fan. This can help dissipate the odor.
- Seek professional help: If the problem persists and the odor is strong, it may be necessary to seek assistance from a professional air conditioner technician.
Remember, addressing the issue of bad odors early on can help maintain a pleasant and comfortable indoor environment.
Mold And Mildew Prevention: Proper Drainage Is Key
To prevent mold and mildew growth and the subsequent odors, proper drainage is of utmost importance. Many window air conditioners do not have an easy way to drain water, but there are solutions available. July, a new window A/C model, includes a convenient drain plug that allows for easy water drainage. This feature ensures that mold and mildew have no chance to thrive and cause unpleasant odors. It’s a simple yet effective addition that sets July apart from other window air conditioners.
If your window air conditioner doesn’t have a drain hole, there are alternative methods to help the water flow out. One effective technique is gently tipping the A/C on its back. This utilizes gravity to assist in the water’s exit, providing a temporary solution until a more permanent drainage option becomes available.

Musty Odors: Addressing Air Filter Issues
Another cause of bad smells in window air conditioners is a dirty or clogged air filter. Over time, dust, dirt, and other particles build up in the filter, leading to musty and moldy odors when the AC is running.
To address this issue, regularly checking and cleaning or replacing the air filter is essential. By keeping the air filter clean, you not only improve the smell of your window AC unit but also ensure better air quality in your living space.
July takes air filter maintenance a step further by offering advanced air purifying filters that can effectively cleanse the air from fine particulates and pollutants.

Chemical Smells: Refrigerant Leakage Warning
While water buildup and dirty filters are common culprits of bad smells in window AC units, a chemical odor should never be ignored. This smell could indicate a refrigerant leakage, which can be hazardous to your health and the environment.
If you suspect a refrigerant leakage, immediate discontinuation of use is crucial. It is advised to contact the manufacturer, especially if the unit is still within the warranty period. Refrigerant leaks cannot be repaired and typically require a replacement unit. July, for example, comes with a 1-year limited warranty, which can be extended for an additional 2 years upon activation, providing peace of mind for the consumer without the hassle of filling in forms.
In conclusion, a strange odor coming from your window AC unit is often a sign of an underlying problem. Water buildup, caused by inadequate drainage, can lead to mold and mildew growth and musty odors. Regularly checking and cleaning or replacing the air filter is essential to maintain good air quality and prevent musty odors. However, if your window AC emits a chemical smell, it may indicate a refrigerant leakage, necessitating immediate action. July AC offers an innovative solution with its easy drain plug, advanced air purifying filters, and reliable warranty, making it an excellent choice for those looking to replace their old window AC unit.

Frequently Asked Questions
Should I be concerned if my AC smells?
If you notice a persistent smell coming from your AC, it is important to address the issue as it could indicate a more significant problem with your AC compressor, fan motor, or wiring. A lingering smell after the initial 20-minute period may suggest a mechanical issue that requires professional attention. It is recommended to have a qualified technician inspect your AC to ensure proper functioning and prevent any potential risks or further damage.
Why won’t my AC smell go away?
If the AC smell persists despite cleaning the condenser and clearing out dirt and debris, it is possible that there may be a more serious issue with your air conditioning system. It is recommended to schedule a professional AC tune-up to thoroughly clean the evaporator coil and unclog the condensate drain. This will ensure that any underlying problems causing the unpleasant smell are properly addressed and resolved.
How long does AC smell last?
Typically, the duration of an AC smell can vary depending on various factors. However, in most cases, the smell tends to fade after the initial use. To avoid any unpleasant odors, it is advisable to ensure proper AC maintenance before turning it off for the winter and performing maintenance again before restarting it in the spring. This proactive approach can help prevent lingering smells and ensure a fresh and comfortable environment when using the AC.
Why does my window AC smell like mildew?
If your window AC smells like mildew, it can be due to several factors. One common reason is the presence of moisture in the unit. Moisture can build up within the AC due to condensation, especially if it is not properly drained or if the unit is not tilted slightly downwards to allow water to flow out. This moisture, combined with dust and dirt in the AC, creates a perfect environment for mildew and mold to grow, resulting in the unpleasant odor.
Another factor could be a dirty air filter. If the AC’s air filter is clogged with dust and debris, it restricts proper airflow and can lead to excess moisture accumulation, making the unit an ideal breeding ground for mildew. Regularly cleaning or replacing the air filter can help prevent this issue and eliminate the mildew smell.
