Ductless split and mini-split systems are relatively new types of air conditioners that have been growing in popularity in recent years in the Greater Las Vegas, Nv area. As their name implies, these air conditioning systems manage to cool your home without needing ductwork for the cooled air to pass through. This is of particular benefit if your home doesn’t already have ducts installed or if there simply is no room for them even if you wanted to put them in. These air conditioning units are generally very energy efficient as well.
