Unclean Air Filter

A filthy air filter is the main cause of an odorous air conditioner. On the filter, grime, dust, and other debris can build up over time, providing the ideal conditions for mold and bacteria to flourish. These particles are blown into the air when the air conditioner is on, leaving behind an unpleasant stench.

Simply clean or change the air filter to solve the problem. Depending on how frequently the device is used, this should be done every few months. This will not only get rid of any unpleasant odors, but it will also make your house’s air quality better.

Mildew and mold

It’s possible that mold or mildew has grown inside the air conditioner if you’ve cleaned or changed the air filter but the odor persists. When the appliance is left unattended for a long time and dampness builds up inside, this can occur.

You must thoroughly clean your air conditioner in order to resolve this problem. Turn off the unit’s electricity before removing the front cover. Then, carefully scrub away any mold or mildew that is still visible using a soft brush. Next, spritz the interior of the appliance with a mixture of water and vinegar that has been mixed in equal parts. Prior to reassembling the device, rinse it with water after letting the solution sit for 10 to 15 minutes.

Death of Animals

Unbelievably, small animals like mice and birds can occasionally enter the air conditioner and become imprisoned, producing an unpleasant odor. It’s crucial to turn off the appliance and contact a specialist to securely remove the animal if you have any suspicions that this might be the case.

Electricity Problems

An unpleasant odor emanating from the air conditioner may occasionally be the result of an electrical problem. This is especially true if the odor smells like melting or smoldering plastic. In this situation, it’s crucial to switch the appliance off right away and make a professional repair call.

In summation, a number of factors, including a clogged air filter, mold and mildew, or even electrical problems, could be to blame for your window air conditioner’s foul odor. The secret is to locate the cause of the odor and take the necessary steps to address it.
