Whole-Home vs Mini-Split Calculator

Ducted central system or multi-zone mini-split?

This tool compares the installed cost of a ducted central heat pump against a multi-zone mini-split for your state and number of zones. Ducted usually wins on whole-home cost when ducts exist; mini-splits win for additions and no-duct homes.

Frequently asked questions

Is a mini-split cheaper than central air?

For a whole house with existing ducts, central is often cheaper; for additions, no-duct homes, or per-room control, multi-zone mini-splits can be more cost-effective. The calculator compares both for your state.
