Let’s take a look at how dirty coils can negatively impact your AC:
- Energy efficiency. Your coils circulate a chemically designed refrigerant, whose phase-changes, and fluctuations of pressure and temperature. In order to cool your home, and move the heat drawn from the indoors to the outdoors efficiently, the coils have to be free of dust and any other debris. If they become dirty, they cannot not disperse or absorb thermal energy effectively and this throws off the entire system.
- Performance. During the long hot summer, you need your AC to perform effectively. You expect it to cool your home without too much strain being put on the system. It was, after all, designed with that purpose in mind. But if your coils are dirty, then the heat transfer and cooling will not be as effective. The barrier of dust and debris on your evaporator coil will create an obstacle for cooling.
- Longevity. Dust and other debris kill air conditioning units. Without professional maintenance, your AC will simply not be able to live up to its projected service life. Unless you want to replace your AC prematurely, you would do well to keep your AC as clean as possibly. Professional routine maintenance, as well as taking care of any necessary air conditioning repairs along the way, is the easiest way to do that.
