This summer of 2025 is expected to be hotter than last year. Before the hot summer, Samsung Electronics, LG Electronics, Winnia, and AUTECH Carrier are offering free air conditioner pre-inspection services every year. If you want to get a free inspection of your air conditioner at home, let’s take a look at the pre-inspection period, how to apply for A/S, and how to do it yourself.

The advantage of pre-inspection is that traveling expenses (basically saving 20,000 won) and inspection fees are free. However, you will only be charged for parts if there is a problem. If you apply for A/S in the middle of summer, not only will you be charged for travel expenses, but you may have to wait for more than a month due to backlogs, so it is recommended to get a free inspection before it gets hot.

2. How to apply for free air conditioner pre-inspection service A/S
To apply for a free inspection, you can apply for a pre-inspection through each home appliance company’s service center or website. If you request the service center, an engineer will visit your home and check for refrigerant leakage and drain hose leakage without charging you for travel expenses and labor. However, if it is necessary to replace parts or inject refrigerant due to product abnormalities, costs may be incurred.

7. How to self-check your air conditioner
Air conditioner users can easily check the air conditioner machine for abnormalities through the home appliance smart app. The first thing to check is the power outlet and breaker when the air conditioner does not turn on before use, and if the remote control does not work, it may be due to battery discharge. You can check whether the remote control battery is dead or not by using infrared signals in the camera mode of your cell phone.

Before summer, if you notice that the air conditioner is blowing weakly or smells bad, you should clean the filter to remove dust. Before using the air conditioner, take out the dust filter, hold it at an angle under running water, and gently wash it to remove dust residue. The air conditioner filter is a very fine filter, so if it accumulates a lot of dust, it can reduce the airflow.
Cleaning your air conditioner
Dog or cat hair often gets caught in the filter, especially if you open the door a lot for ventilation or if you have pets. It’s a good idea to clean your air conditioner’s filter once or twice a month, and regular cleaning can save as much as 10.7 kWh per month. If your outdoor unit isn’t blowing cool air, it’s a good idea to clear the area around it and tidy it up so it can breathe better.
