    Difference Between Central AC, High Velocity AC and Split Ductless AC?

    Central AC cools your whole home through ducts; High Velocity AC uses small, flexible tubing for older homes; Split-Ductless AC cools individual rooms without ducts using wall-mounted units.

     

    Yes, split-ductless ACs are quieter, more energy-efficient, and provide better cooling without blocking windows like traditional window units.

     

    A heat pump is an efficient device that provides both heating and cooling. It moves heat rather than generating; it transfers heat from outside to inside and vice versa, depending on the season.
