What problem is it with my air conditioner, which I bought for 15 years and has been running for 9 years? Two weeks ago the room temperature was around 26 degrees Celsius even when set at 26 degrees. But now, after reaching 40 degrees outside, the room temperature can only reach 29 degrees Celsius no matter how high the setting. What's wrong with it? |
