Imagine it’s a hot summer day. You just got home, turned your AC, and got a vinegar smell. The first thing is to wonder, “Why does my air conditioner smell like vinegar?” Then you start looking for answers. An unpleasant vinegary odor from the ac indicates that there is a problem.
Without question, the AC is due for repair and maintenance. Usually, if your AC is working correctly, you should come home to a smell-free comfortable space. The only way to get to the bottom of it is to find out why the smells are present in the first place.
Why Does My Window Air Conditioner Smell Like Vinegar
Before getting into the maintenance process when your AC has a vinegar smell, it’s essential to know some of the things that could be causing the smell. Here are some potential answers for when you ask yourself “why does my air conditioner smell like vinegar?”:
- Mold and Bacteria
Some of the most common causes of issues with air conditioning in a home are mold and bacteria. The two thrive in moist conditions, which would happen if your AC isn’t expelling moisture as fast as it should. Moisture plus the warm conditions make it absolute for mold and bacteria to exist.
There are mold species that produce a scent like that of vinegar. Mold often populates and gathers in the ducts. Unless you clean the ducts regularly, the mild continues to grow while feeding on dust and dead skin cells.
If you want to confirm that mold and bacteria are the sources of the smell, check for pans of condensation and blackish fuzz on the surface of the AC. Also, rethink staying in a space containing air contaminated by mold spores as it could lead to respiratory issues.
Pans of moisture appear in the AC when the condensation if the unit fails to evaporate as quickly as it’s produced. Manufacturers design AC to have optimum condensation levels to function correctly. The condensations will likely evaporate slower if you live in humid regions due to oversaturation.
Once the water collects and forms pans, it produces an odor your senses perceive as a vinegary smell. If it’s not a vinegary odor, then it’s musty. You can know if your AC has this problem by checking if the condensation pan has standing water.
Another indication is that the standard water drip stops. It’s better to take care of the problem as soon as you notice it, as it causes the AC to stop working efficiently.
- Faulty Filter
It’s easy for the air filter in an AC to get damaged. Any damage to the filter keeps it from performing as it should. In addition, a damaged air filter does not purify the air, so toxins and microorganisms might fill your air space.
- Issues with the Motor
If your air conditioner has a malfunctioning electric motor, the motor is likely to produce ozone which has a sour smell. Ozone is a product of using electricity. Typically, an AC produces an undetectable amount of ozone.
The urgent vinegary order should alert you that you have a possible leak. Note that the gas is harmful, so it would be best to clear an area with a leak.
Eliminating Vinegar Smell from an AC
After knowing what could be causing the vinegary smell in your AC, the next thing is to find solutions. Consider consulting an expert on air conditioning maintenance to ensure whatever you do doesn’t add to the list of problems. Here are some answers to help cure a vinegary odor from your AC.
- Clean the Filters
A dirty filter contains mold and microorganisms, which cause respiratory diseases besides causing an unpleasant smell in your space. You may clean the filter yourself, or you can hire a professional to do it on your behalf.
Besides cleaning the filter, the other alternative is to replace it. It’s a straightforward process that should take a few minutes, especially if you know your way around an air conditioning unit.
- Dry the Stubborn Condensation
As mentioned earlier, mold and bacteria do well in moist conditions. You can dry out excess moisture by switching the Ac off for the fan to blow out the moisture. Leave the fan running for about three minutes to ensure you get results.
It’s essential to invite experts to clean the ductwork as well. Do this to ensure you eliminate moss spores to keep them from growing back too soon.
- Clean the Vents
The vents, too, might contain mold and debris, which produces vinegary fumes over time. Cleaning the ducts eliminates the smell and improves the AC’s efficiency.
Tips to Prevent Vinegar Smell In the Air Conditioner
Instead of waiting for a time when you have to ask yourself a question like “why does my house conditioner smell like vinegar” there are things you can do to prevent it. For instance, an expert’s frequent inspections of the air conditioner are essential to rule out damage to the filters.
Routine maintenance should follow inspections. Even without the smell, you should schedule an expert to clean the vents and the filter of your AC. Also, if mold develops in the unit, it will be best to get rid of it before it emits smells.
