Ductless Heat Pumps or Variable Refrigerant Flow (VRF)

Go ductless to solve comfort, space issues

How it works

Ductless heat pumps, also known as mini-split or multi-split systems function much like traditional heat pumps. A ductless system, however, has one or more wall or ceiling mounted indoor units that are connected to an outside unit by refrigerant lines.



  • Energy efficiency — no ducts, zoning capability and higher efficiency variable speed compressors
  • Ease of installation — retrofits and room additions
  • Comfort — higher heating supply air temperature and ability to solve comfort issues in problem areas
  • Space — solution for limited access attics or where space is not available for a duct system
  • Aesthetics — eliminate unsightly window units; flexible indoor design options such as wall hung or ceiling mounted
  • Sound — quieter operation especially compared to window units
