Mini-Split System FAQs

What is a ductless mini-split?

A mini-split system uses an outdoor unit and one or more indoor units to provide heating and/or cooling without conventional central ductwork.

How do I choose the correct BTU size?

System sizing depends on the building and application. Use appropriate HVAC sizing methods or professional guidance rather than selecting by room size alone.

Are line sets included?

Included components vary by product. Check the exact listing before ordering.

Can I request pricing for multiple systems?

Yes. Submit model numbers, quantities and delivery ZIP through Request a Quote.
