If your air conditioning’s evaporator coils get dirty, that can lead to them getting completely jammed.
This can easily harm the performance of your central air conditioning unit, plus make it eventually break down on you. This is why it is honestly pressing to have a certified HVAC specialist come to your house to do preventative work on your central heating plus a/c on a semi regular basis. This will include cleaning your central a/c’s evaporator coils; Of course, another way you could look after this one aspect of your central heating plus a/c, would be to completely do it yourself. This can also be done if you know what you are doing! You would first turn the a/c off by using the “off” button on the control unit. The next thing you would do, is to remove all screws plus other latches on the access panel of the a/c, then following this, place these things in one place so nothing gets lost when you are finished, especially the screws! Or you are “screwed”! Then, the best way to scrub the coils out would be with some kind of compressed air across the coils in the other direction of the regular air flow. Try to avoid blowing any dirt, dust, grime or dander into your air duct! That is honestly pressing, or you could end up with a whole current set of troubles that will require a good air duct cleaning. These are the basics for DIY air conditioning coil cleaning.
