Why is my AC giving off bad smell?
Musty smell is a common problem when it comes to air conditioners.
It’s an unpleasant odor that can be caused by a variety of factors, including HVAC duct problems, clogged filters, clogged drain lines, and mildew or mold buildup.
In order to get rid of the musty smell, it’s important to determine the source of the odor, and then take the appropriate steps to get rid of it.
How to get rid of bad smell from air conditioner
The best way to get rid of bad smell from an air conditioner is to regularly clean the filters and coils.
Additionally, changing the air filter every 1–2 months can help reduce odors, while using an air purifier can eliminate any lingering smells.
How do you get a musty smell out of an air conditioner?
One of the most common causes of a musty smell in an air conditioner is clogged filters.
If the filter is not changed or cleaned regularly, dust, dirt, and other debris can accumulate, leading to a musty smell.
Clogged drain lines can also be a source of musty smells, as the water accumulation can lead to mold and mildew growth.
What to do?
Once you’ve identified the source of the musty smell, you can take steps to get rid of it.
1. Carefully remove the outer case of the air conditioner and move it to a secure place.
2. Then, blow compressed air through the coil and the ducts, and use a brush or cloth to clean any finer dust particles.
3. Clean the vents and the ducts, and flush the drip tray with a cleaning solution.
4. Allow the air conditioner to dry completely, and then reassemble it.
If the musty smell persists, or if you find evidence of mildew or mold, it may be time to call a professional.
A professional can inspect the location and extent of the mildew, as well as any moisture or filth that may have collected in the coil and ductwork.
Types of Air Conditioner Smells, Possible Causes and What You Can Do
In addition to musty smells, there are a few other types of air conditioner smells and their possible causes.

3. Rotten Eggs
If it smells like rotten eggs, it may be due to a chemical leak, such as Methyl Mercaptan.
4. Skunk
If it smells like gas or skunk, it could be due to a natural gas leak.
