AC repair cooling and heating

Unfortunately, even regular maintenance does not guarantee that the AC will not need to be repaired. Among all the reasons we can highlight: non-professional installation; dirty filter of the indoor unit; Freon leak; poor cooling, condensation, shutdown after a few minutes of operation and unusual noises are signs that the air conditioner needs urgent repair. So for proper heating or cooling of your room checkups are necessary. Always be aware of the outdoor temperature. Most models are simply not designed to heat properly if the temperature outside is below 0 Celsius. If the weather allows your AC to work first thing you need to check is for the AC to be in a heating mode. Perhaps you weren't paying attention. But the default is always the "Cool" mode. Press MODE on the remote and find the Heat mark or the sun icon. If the air conditioner does not operate on heat, but at the same time blows from the indoor module, and the compressor is running, the reason may be a breakdown of the four-way valve. This valve is very important, it is responsible for the transition from the "winter" to the "summer" mode and vice versa. When the air conditioner is not running on heat, the compressor does not start when power is applied, but an air jet is blowing from the indoor unit, the problem is probably in the compressor. It needs to be repaired or changed.
