As soon as winter arrives, many people switch off their air conditioners (ACs). But just switching off the AC is not enough. If you do so, it may negatively impact its performance and lifespan. If you have stopped using your AC, it is very important to take proper care of it. First of all, remove the AC filters and clean them thoroughly. Dirty filters can spread dust and bacteria into the air, so periodic cleaning is important. It is important to clean not only the indoor unit, but also the outdoor unit. If it gets filled with dust, leaves or debris, it affects the cooling system. Therefore, it is better to get service from a professional once in a while. After cleaning the outdoor unit, it should be covered to protect it from dust and moisture. This way you can protect the machine from damage. Apart from this, also get the drain pipe cleaned by a technician. If the pipes become clogged, water can accumulate and cause leakage problems. These small steps will help keep your AC efficient longer and cooler next summer.
