High Velocity HVAC Systems

 Zoned Comfort with No Ductwork Required 

Cool the Rooms You Actually Use

 

Ductless mini-split systems are a flexible, efficient way to cool specific areas of your home — without needing ductwork. Whether you’re finishing a basement, upgrading an office, or fixing that one room that’s always too warm, CRS Heating and Air Conditioning, Inc. installs clean, professional systems that deliver comfort where you need it most.


We work with trusted brands and tailor every installation to your space.

Is Ductless Right for You?

Mini-splits are perfect for hard-to-cool areas like sunrooms, attics, additions, or garages. They're also ideal for older homes without ductwork, or households that want room-by-room temperature control instead of cooling the whole house at once.


Each unit works independently — so one room can be set to 72° while another stays off completely.
