The article specifically brings you the causes of this odor and how to remove it. I hope you will like it.

The first reason for the air conditioner to have odor

1. After years of use, the air conditioner will squeeze a certain amount of dust inside the indoor filter and copper sheet. When it accumulates to a certain amount, it will produce a certain odor. When the air conditioner is turned on, the odor will float into the air.

2. Because the air conditioner will have moisture inside the indoor unit in many cases after cooling and heating, so when the air conditioner is turned off, the air conditioner without drying and mildew prevention function will stop immediately. In this way, the moisture inside will always exist, and mold will be produced over a long period of time, and the musty smell will naturally be produced.

3. Dust in the air may also have an odor, or the air in your room may not be very good. During defrosting, the compressor will run at high speed, and the smell may be caused by the plastic on the compressor encountering high temperature.

The second method to remove the odor of air conditioner

Step 1: Clean the outdoor unit condenser and fan. There is no need to remove the outer casing. Just rinse with tap water, being careful not to get water on the electrical components.

Step 2: Clean the internal filter, open the movable outer shell, remove it, and rinse it with tap water.

Step 3: Clean the indoor evaporator. Open the movable outer shell and remove the filter to see the metal fin evaporator. Prepare a bottle of special air-conditioning cleaner (usually sold in large supermarkets). Spray the cleaner evenly into the evaporator with the power off. Wait for fifteen minutes and then start the air conditioner. The dirt will flow away with the condensed water.

Here’s why your air conditioner has an odor, and how to get rid of it. As you can see, the air conditioner has an odor because we do not clean and maintain it enough on a regular basis. There are more and more clothes in the air conditioner, and the air becomes damp, which creates a bad smell that is blown out of the air conditioner along with the air flow. Moreover, if the air conditioner is not cleaned for a long time, the wind power will become smaller and smaller, which will directly affect the life of the air conditioner.
