Regularly cleaning or replacing the filters on your ac units plays an essential role when it comes to maintaining them properly. A dirty or damaged filter will affect your home's air quality and place extra strain on the ac unit’s motor.
Air conditioning units that are outside are often exposed to all the elements. This will cover them in every kind of debris and dirt. The first step, then, is to clear away this debris, including branches, leaves, and spider webs, etc. that have accumulated around the unit. The next step will be to remove the cover of the ac unit which will allow you to clean the inside as well. Inside you will find hundreds of metal fins surrounding coils of piping. You may notice that some of these metal fins are bent. These can be straightened again using a tool called a fin comb.
Drainage lines are fitted to central ac units which draw away condensed water. If these drainage lines become blocked, which can happen over time, the air conditioner will not work optimally. As you clean your air conditioning unit, make sure these lines are not clogged and check that they are attached firmly to the unit.
Finally, if your ac unit requires oil, be sure to check the operating manual first to know what type of oil you should be using for your unit.
