Full system vs one unit

Replacing both the indoor and outdoor units together is usually the best choice, since matched systems deliver their rated efficiency and keep the manufacturer warranty intact. A partial replacement can make sense when one side is newer and in good shape. We will tell you honestly which fits your system.
