Air conditioning systems use two sets of coils to cool your home: the condenser coils that are in the outdoor unit and the evaporator coils that are in the indoor unit (if you use a ductless cooling system, these coils will be inside the blowers). The coils play a major role in the heat release/cooling process, so it is important that they are well-maintained. During annual or bi-annual maintenance, they will be carefully and thoroughly cleaned. Otherwise, problems will ensue.
The coils in your AC system are very small metal tubes that are constructed in a serpentine fashion. This is because the snaking is crucial the cooling process. In the condenser coils, the refrigerant snakes its way through the coils, releasing heat as it goes; in the evaporator coils, the refrigerant snakes its way through the coils absorbing heat.
However, the coils can be delicate, and when they wind up covered in a layer of dirt and dust, as they naturally will after each cooling season due to wear and tear, this layer will start to act as an insulator. Insulation is not good for either set of coils, and will interrupt the heat release/cooling process.
You may see evidence of this in a couple of ways. One is icing on the evaporator coils. Simply scraping the ice off does not fix the problems; the coils need to be cleaned. Another problem you may see is warm air blowing into your home. This is indicate that the system is able to release the heat as needed in order to cool.
