Educational starting point
Mini-Split Size Explorer
Use room dimensions and common load factors to create a broad discussion range—not an equipment selection.
Planning aid only. This tool provides general education from visitor-entered information. It is not a diagnosis, Manual J load calculation, equipment selection, safety inspection, proposal, price, warranty or guarantee. Property conditions and equipment requirements must be reviewed onsite.
Why an onsite review still matters: room-to-room load, construction details, outdoor design temperature, low-temperature heating capacity, line-set layout, condensate drainage, electrical requirements and multi-zone diversity can materially change equipment selection.
