Reasons for Why your Air Conditioner Smells bad – Speedy fix:

As we discussed earlier, the bad smell from an Air Conditioner includes several types of Odours which help in finding the problem in AC. So, here are the types of odors and causes from an AC.

Moldy Odour:

We all know that AC drips off water during the process of cooling due to the condensation process which takes place inside the AC unit. This dripped water drains in a pan and then comes out through a drain line. During the process of water draining, these are some chances of stocking water. The stocked water creates the best environment for molds to grow and even faster if there are more mildews. Air passing from the filters along with the moldy smell from the mildews results in bad smell from AC.

Speedy Fix:

Wipe out the visible mildews with a vinegar solution. You can even vacuum your AC with a Wet-dry vacuum cleaner to remove the stubborn mildews.

Smoke/gas Odour:

Every AC consists of a refrigerant which is also called a cooling agent. It is one of the main components required to flow in the coils of an AC. As this is fluid in nature, it sometimes tends to leak. The leaked refrigerant smells release a smoke/gas smell even though there is no presence of gas inside an AC unit. The leaked refrigerant also causes danger to an AC.

Speedy Fix:

If you observe any of the smoke/gas smell then you need to make a call to the serviceman as you cannot detect the leakage and refill the refrigerant.

Electronics Burning Odor:

The working of an AC consists of many components including a compressor, fan motors…etc. If any of these are components got damaged due to a blown fuse, then you can observe a burning smell from the air conditioner. 

Speedy Fix:

Right after observing a burning smell, you need to switch off the mains power supply and make a call to the serviceman to figure out the issue and replaces the damaged part with a new one by him.

Rotten Egg Odor:

An AC has 2 units one is on the inside of the room and the other is outside of the room. Not only the problem of bad smell (what we discussed till now) comes inside the unit but the problem happened the outer unit of AC can cause a bad smell inside the room. As the outer unit is free for the atmosphere, there are high chances for small animals, birds to get stuck inside the air duct, which circulates air inside from the outer unit. The decomposed flesh can cause the rotten egg smell in the room while running.

Speedy Fix:

As the odor is horrible to bear, you need a professional to clean because of the normal methods that we used to clean are not enough to remove the body’s remains and smell. So, make a call for the professional cleaner to clean those areas of dead things.
