Did you think that you could totally break your AC when you first buy it? Buying an a/c is quite easy, then do some research, decide if you want it ductless or not! Then you option out the size, model & where you want the cooling method to be, however next is to have a cooling system corporation in to do the AC replacement, and a lot of people skip right over this step, then since buying a cooling system is so easy, installing it should be too, well that is totally wrong. Do not install your AC method by yourself… Get a professional to do the replacement, however most people who install their own cooling method do it totally wrong… If the AC is not hooked up respectfully well, expect big energy bills. The a/c is not easily working as efficiently as it could be. Also the a/c is more likely to have total breakdowns when not installed or handled correctly. The biggest mistake a man can make is with refrigerant. There is a set level of A/C refrigerant that needs to be in the AC method on the first set up. If you don’t study the instruction & fill it to the right level, you have a wrecked cooling system. The cooling method will not perform well & have a major malfunction easily early in its own lifespan, however you basically kill the AC if you mess up the initial refrigerant & replacement. So don’t ease out with AC replacement, just have a good AC corporation do it for you. That way you think it is done right & you will have no future bad issues.
