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.
Is a split-ductless AC better than a window unit?
Yes, split-ductless ACs are quieter, more energy-efficient, and provide better cooling without blocking windows like traditional window units.
What is a heat pump?
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.
