There are several steps to operating a ducted air conditioner efficiently. It is imperative that the temperature is set to the most efficient levels, between 22 and 24 degrees when cooling, and 19-21 degrees when heating. Make sure you also take advantage of the zoning capabilities of your Fujitsu General ducted air conditioner to provide the optimum level of comfort to each room. For more information, please refer to our article on how to zone ducted air conditioning. For your ducted air conditioner to work at its best, ensure your home is well-insulated, and that the air conditioning system itself is regularly maintained by a professional. Using smart controls to set timers, or switching the unit off when it is not needed, can also significantly reduce the amount of energy used by your ducted air conditioner.
