Ductless AC (Mini-Split Systems)

 Compact, Powerful Cooling for Older Homes and Tight Spaces 

Need Cooling in a Home Without Ductwork?

High velocity HVAC systems deliver strong, even cooling through compact, flexible tubing — perfect for homes where traditional ductwork just won’t fit. Whether you live in an older home, have a finished attic, or want to avoid tearing up your walls, CRS Heating and Air Conditioning, Inc. can help.


We install and service high velocity systems from trusted brands like SpacePak and Unico — with less mess and disruption than traditional ducted systems.

Is High Velocity Right for Your Home?

These systems are ideal for:

  • Homes without existing ductwork (like radiator-heated homes)
     
  • Historic homes where preserving structure is important
     
  • Finished attics, basements, and tight retrofits
     
  • Remodels where standard ducting isn't possible
     
  • Homeowners who want quiet, fast, even cooling
