Depending on your location and what you already have in place within your home will determine what type of air conditioner you need. If you are in a more tropical environment with no need for heat then it would be a waste of money to install a reverse cycle split system, and ducted air conditioning would be best. But if you lived in a house with no heating and it can get quite cold during winter then a reverse cycle air conditioner would be the perfect addition to your home, rather than ducted air conditioning.
