If your air conditioning’s evaporator coils get dirty, that can lead to them getting completely clogged.
This can really harm the performance of your central air conditioning unit, and make it eventually break down on you.
This is why it is very important to have a certified heating and air conditioning specialist come to your home to do preventative work on your central heating and air conditioning system on a semi regular basis. This will include cleaning your central air conditioning system’s evaporator coils. Of course, another way you could look after this one aspect of your central heating and air conditioning system, would be to completely do it yourself. This can also be done if you know what you are doing! You would first turn the air conditioning system off by using the “off” button on the thermostat. The next thing you would do, is to remove all screws and other latches on the access panel of the air conditioning system. 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 clean 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 ductwork! That is very important, or you could end up with a whole new set of problems that will require a good ductwork cleaning. These are the basics for DIY air conditioning coil cleaning.
