Split system air conditioners derive their name from the fact that the condenser is installed outside the house whilst the fan coil is installed inside. When cooling, warm air from inside the room is taken in by the fan coil and removed, resulting in cool air recirculating back into the room. For heating purposes the reverse happens during cold days.
Wall mounted split air conditioners are the most commonly installed air conditioning system because they are affordable and easy to maintain. Split systems have inverter technology. Inverters control the compressor rotation speed more accurately and this results in more comfort throughout the year by maintaining a constant temperature. Moreover it saves electricity and produces less noise when used.
On average a 2.5kW split system installed in a small room providing regular heating and cooling during the winter and summer periods, the yearly cost is approximately $280. You can reduce the running cost of the split system by setting a higher cooling temperature and a lower heating temperature via he economy setting. Keep the sun's heat from entering by closing curtains and blinds during daylight hours. Closing windows and doors to prevent air from escaping when the split system is running. You can also insulate your home to increase the cooling and heating effects of the air conditioner.
Split system wall mounted air conditioners are cheaper to install for small rooms and apartments because the units themselves are relatively cheap to purchase and there is no duct work required. Each wall mounted unit has independent temperature control saving more electricity where temperature control is not required. Split air conditioners also permit you to install air filtering and humidity control functions which regulates the amount of dust and humidity in a room. Sensitive children and allergic customers will find this feature useful.
