Brand new window air conditioners can be an excellent addition to your home, providing much-needed relief from the heat during the summer months. However, one issue that can arise with new units is an unpleasant smell. If you’ve recently purchased a new window air conditioner and are noticing an unusual odour, you may be wondering what’s causing it and how to get rid of it.
Understanding Air Conditioner Smells
There are several reasons why a brand new window air conditioner might produce a strange smell. One of the most common causes is the off-gassing of chemicals used during the manufacturing process. This smell should dissipate after a few days of use. However, if the odour persists, it could be due to other factors such as mould, mildew, or bacteria growth.
Preventative Maintenance and Cleaning
One way to prevent unpleasant smells from your window air conditioner is to perform regular maintenance and cleaning. This includes cleaning or replacing the air filter, cleaning the evaporator coil, and emptying the drip pan. Doing this regularly will help prevent the growth of mould, mildew, and bacteria, which can cause odours. Additionally, it’s essential to ensure the unit is installed correctly and used properly to avoid any issues that could lead to unpleasant smells.

Understanding Air Conditioner Smells
If you’ve recently purchased a brand new window air conditioner, you might have noticed some strange smells coming from it. While it’s not uncommon for new appliances to have a slight odour when first turned on, persistent or strong smells can be a cause for concern. In this section, we’ll explore the common causes of smelly air conditioners and how to identify different types of AC smells.
Common Causes of Smelly Air Conditioners
There are several reasons why your brand new window air conditioner might be producing a bad smell. Some of the most common causes include:
- Microbial growth: Mold, mildew, fungus, and bacteria can all grow inside your air conditioner if it’s not properly maintained. These microorganisms can produce a musty or sour smell that can be particularly noticeable when you first turn on your AC.
- Refrigerant leak: If your AC smells like chemicals or has a sweet, pungent odour, it could be a sign of a refrigerant leak. Refrigerant is a toxic substance that can be harmful to your health, so it’s important to address this issue immediately.
- Dead animal: If you detect a foul, rotting smell coming from your AC, there could be a dead animal trapped inside. Birds, rodents, and other pests can sometimes get into your air conditioner and die, producing an unpleasant odour.
- Burning smell: If your air conditioner smells like something is burning, it could be a sign of an electrical problem. This could be a serious issue that requires professional attention.
- Dirty filter or coils: If your AC smells like dirty socks or has a musty odour, it could be a sign that your filter or coils are dirty. Regular cleaning and maintenance can help prevent this issue.
Identifying Different Types of AC Smells
Different types of smells can indicate different problems with your air conditioner. Here are some common AC smells and what they might mean:
- Musty smell: This can be a sign of microbial growth, such as mold or mildew. It’s important to address this issue promptly to prevent further growth and potential health problems.
- Rotten egg smell: This can be a sign of a gas leak, which can be dangerous. If you detect this odour, turn off your AC immediately and contact a professional.
- Fishy smell: This can be a sign of a refrigerant leak, which can also be harmful. Contact a professional immediately if you detect this odour.
- Smoke or burning smell: This can be a sign of an electrical problem or overheating. Turn off your AC immediately and contact a professional.
- Weird or bad smell: If your AC smells strange or unpleasant, it’s always a good idea to investigate the cause. Regular maintenance and cleaning can help prevent many common AC smells.
In conclusion, it’s important to pay attention to any strange smells coming from your brand new window air conditioner. By understanding the common causes of smelly air conditioners and how to identify different types of AC smells, you can take steps to address any issues and keep your home comfortable and healthy.

Health Implications and Indoor Air Quality
If you have recently purchased a brand new window air conditioner and it is producing an unpleasant odor, it’s important to consider the potential health implications and indoor air quality.
Effects of AC Smells on Health
The smell from a new air conditioner can be caused by a variety of factors, including mold and bacteria growth. Exposure to mold and bacteria can cause a range of health problems, including headaches, respiratory issues, and allergic reactions. It is important to address the issue promptly to avoid any potential health risks.
Improving Ventilation and Air Flow
One way to address the issue of unpleasant smells from a new air conditioner is to improve ventilation and air flow. This can be achieved by opening windows and doors when possible, unless outdoor air quality is poor. Air conditioning should be reduced or turned off when doors and/or windows are opened. Additionally, operating exhaust fans (e.g. in toilets, kitchens) at full capacity can help expel air from indoor spaces.
It is also important to ensure that your ventilation system is functioning properly. Consider adding a dedicated outdoor air supply and/or exhaust to improve air flow and reduce the risk of mold and bacteria growth. If you suspect that your air conditioner is producing an unpleasant odor due to mold or bacteria growth, it may be necessary to have it professionally cleaned or replaced.
By taking steps to improve ventilation and air flow, you can help ensure that your indoor air quality is healthy and free from unpleasant odors. Remember to address any issues with your air conditioner promptly to avoid potential health risks.
