Sizing this system
This is a whole-home system: its rated cooling is shared across several indoor units or distributed through ductwork, so there is no single room it does or does not fit. An installer sizes each zone against that room (a Manual J calculation), which is why we do not print a room verdict here.
Installation cost
$5,000-15,000 fully installed depending on the number of zones (roughly $3,000-8,000+ for the multi-zone install on top of the equipment). A 2-room (2x1) setup sits near the lower end, a 4-5 room whole-home system near the top. The unit price you see here is hardware only; installation is the larger, separate cost.
A typical range for this system type, for comparison only, not a quote for this unit. The actual price depends on the line-set run, electrical work and access.

Installation & the rules that apply
This is a multi-split. Same F-gas certified-installer requirement and sub-750 GWP refrigerant rule as a single split, applied across a bigger system. Because it touches multiple rooms and routes pipes through the structure, it more often triggers planning or prior-declaration steps, freeholder, landlord or condominium and shared-wall consent, and neighbour distance and noise rules. Heritage and historic-centre restrictions apply to the outdoor unit just as for a single split, but the single shared condenser is often easier to get approved than several separate units.
