Not every home or business is designed for central ductwork, and in Port Saint Lucie’s climate, reliable cooling is essential.

Installing a mini-split requires careful planning to ensure maximum efficiency and performance. Legacy Heating & Cooling evaluates each space to determine the best system size and placement.
