The evaporator units and fan coils in air conditioning systems and heat pumps perform the primary function of these systems by transferring heat. Both types of coil extract heat from the indoor air and send it to the outdoor condenser where it circulates through the condenser coils to dissipate the heat. If you use a heat pump, the fan coil unit contains refrigerant and an additional heating element for winter operation.

Regardless of the type of coil your system uses, both should be considered for optimal performance. The new cooling system or heat pump coils are completely clean, which speeds up the heat transfer process. Keeping the coils as clean as possible over the long life of the HVAC system is an important part of system maintenance, which keeps your equipment running more efficiently and longer.
What Do I Have To Do
The clean air filter traps dust in the air which will coat the evaporator and fan coil, reducing their performance. Dust acts like insulation on the coils and when coated not much heat exchange can occur, slowing down the cooling of your home. If you use the heat pump in winter, the dust on the coil will also affect the heating performance.
Since the humidity in this area is very high, mould and a layer of bacteria can also grow on the coils. As the cooling system runs, moisture in the air condenses on the coils, providing an ideal environment for biological growth. Keeping the internal humidity below 50 per cent helps prevent biological overgrowth on the coil.
