The principle of the air conditioner is quite simple, but I am still afraid to fix it myself. My friends advised me to clean the air conditioner every year. Initially, I did not understand why to clean AC. When I first contacted these guys https://www.airconservicingsingapore.com/ I was surprised at how much debris they pulled out of the air conditioner. If I hadn't gone to the professionals, my family would be breathing all that stuff. Now I tell everyone that the air conditioner needs to be cleaned if you don't do it you risk the health of your loved ones.
