Strange smells from the AC unit can be scary, and they should be so. While most of them are harmless smells caused by a clog or moisture entrapment, others can be dangerous for your AC as well as your health. So how do you identify the smells, and what do they mean? Let’s find out. Here are the five most common AC smells and what they mean.

1) Electrical Odours

You should first turn off the AC unit if you notice any electrical odour that resembles the smell of gunpowder. Then, you should check the air filter. A dirty air filter can cause the electric resistance heaters to overwork that can cause overheating. If the filter is clean, then there might be an issue with the motor or the wiring. You should not try to fix this on your own as it can cause severe injury. It would be best to call a professional technician to repair it.

2) Rotten Egg Smell

If you notice a hint of rotten egg smell in your house that is not coming from your fridge, it is a sign of a natural gas leak, like sulphur, within your AC unit. Natural gas is odourless, so utility providers add the pungent smell to alert you if it starts leaking. You should not take this lightly as it can be dangerous to life. When you notice this, you must open all the windows, get out of the house immediately, and contact a professional technician as well as the gas company.

3) Mouldy Smell

On the other hand, if you notice the musty smell of mould or mildew, there is not much to worry about. It is a fairly common ailment. There is a lot of condensation within your AC. So if the moisture fails to escape out of the drain properly, it can get stuck to the surfaces and cause mould to grow. Here, you can try finding and cleaning the most. If the problem persists, you should contact a technician to check the AC drain as there might be an issue blocking the flow of moisture.

4) Smell of Old Socks or Feet

Similarly, if your AC emits the smell of old socks or stinky feet, then it is a sign that there was water clogged within your AC unit. You should first check the drainpipe to see that it is clog-free. If the water is not flowing out of it, you should contact a technician to clear it up.

5) Exhaust Fume Smell

Another smell that you should worry about is the exhaust fume smell. Of course, your AC does not run on gas, but this smell can also be caused by the various oils and chemicals present within your AC. To check, you should first look for any leaks around the tank and the filter. If you spot a leak, all you need to do is find the source and tighten the bolts. If you don’t see any oil leaks, then it is a sign that the oil burner is not functioning correctly. It could be because of a damaged or clogged fuel pump. In this case, it is time for an air conditioner repair.
