Reasons Why Your AC Smells

If you’ve noticed that your ac is smelling like a chemical factory, there are a few things you can do to combat the odor. You can install an electrostatic air filter, but you should consider how this can affect the air quality in your home. Another cause for the odor could be a paint thinner, formaldehyde, or mildew smell. If you notice that your AC is smelling, it’s time to take action. Regular AC maintenance in Sharjah can also help you overcome this issue.

Paint thinner:

If you’re noticing paint thinner smells in your ac, there’s more than likely a leak somewhere in your system. Paint thinner is a volatile organic compound or VOC that can smell like paint. Your AC unit often emits these vapors, and if you inhale them at high enough levels for an extended period, they can even make you feel nauseous or dizzy. There are ways to remove the smell from your ac unit, and this article will go over a few of the most common solutions.


If you notice a strong, pickle-like odor coming from your air conditioner, you may have a problem with formaldehyde. This chemical is a byproduct of combustion and is commonly found in automobile exhaust. Tobacco smoke is also a common source of formaldehyde in the indoor environment. Regardless of how you determine the source, it is crucial to avoid formaldehyde in your air conditioner.


A musty odor coming from your air conditioner could be due to mold or mildew. These two types of mold grow in areas with high moisture content, making your air conditioner a prime breeding ground. In addition to making your air conditioner smell musty, mold can also trigger allergies and worsen asthma symptoms. Additionally, your air conditioner is commonplace to find mold spores, as it continuously distributes them throughout your home when it runs.

Electrical problems:

There are many causes of fishy odor from your AC. Overheating electrical components can lead to a fishy odor and a potential fire hazard. Unless you notice that your air conditioner is leaking water, you should contact a licensed HVAC technician to investigate. If you smell gunpowder, it’s probably an electrical issue. If this is the case, call an electrician.
