Zoned Comfort with No Ductwork Required
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.
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.
These systems are great for homes without traditional HVAC infrastructure.
Perfect for bedrooms, nurseries, or offices where noise matters.
Only cool the rooms you actually use — no wasted energy.
Many mini-splits offer both cooling and heating in one system.
No major demolition required — most installs are completed in a day.
Adjust temperature, fan speed, and mode remotely or by room.
We install ductless systems from brands like Mitsubishi, Daikin, and LG, and we handle every part of the process:
