We recommend you test run your air conditioner at this time of the year. Manufacturers get busy with inquiries and repair requests when summer comes, and it could take a long time before your air conditioner is fixed if there is a problem. Here is how you can test your air conditioner, the test is similar for most major manufacturers.
Set the function in “cool” and the temperature at 18 degrees, run it for 10 minutes.
If it does not turn on.
If the remote control works but the wind does not come out. (or is too weak.)
If it smells bad.
It does not cool well.
Check if the outside fan is blocked. Air conditioners need to have enough space around them for air to flow, a minimum of 5cm behind and 10cm sideways, and check it is not clogged with leaves and such.
The light is flashing, and/or the error message is showing
The color of the flashing light or the error number could tell the status if it needs repair or just the wrong operation.
We hope you all stay cool this summer!
