Hello, everyone. I'm Joshua Clement, and today I'm gonna talk to you about how to de-ice a window air conditioner. The reason it freezes up is because of the high humidity in the room. The air conditioner doesn't create cold air it just removes the hot air and when it's pulling that hot air out the condensation that is caused through that process sticks to your coils and ends up freezing. The first step to deicing your window air conditioner is to shut it off and unplug it. Let it sit there and let the warm air from the outside thaw that ice out that way you're not putting heat on there and damaging those coils. You want to let it do it slowly and overtime you don't want to rapidly melt that ice off of there. One reason is all that water is just going to end up melting down and filling up the water tray in the bottom of your air conditioner and overflowing to the inside of the house. You want to let it do it slowly so that way it could filter out through the back of the air conditioner and to the outside. You want to make sure that you aren't trying to scrape the ice off of your coils on the inside that can damage your coils and cause it to freeze up faster. You also want to make sure that you keep your coils clean. Having this dust on here will reduce the amount of air that can flow through it which will cause it to freeze up faster. So you want to just take a rag and wipe off that dust and keep it as clean as possible. It's important to make sure that you aren't running your air conditioner when it is frozen up that's gonna cause the compressor inside to overheat and blow your window air conditioner. Thank you all for watching and good luck with this project.
