ABOUT COOL COST LAB
Useful buying estimates.
Visible limits.
Cool Cost Lab helps room-AC shoppers compare capacity, running cost and inverter payback without pretending a short form can replace local expertise or a utility bill.
Why ranges?
Rooms with the same floor area can have different windows, insulation, ceiling heights, occupancy and climate exposure. A range is a more honest starting point than a precise-looking single number.
What we exclude
Commercial spaces, multiple rooms and central systems need professional load calculations. This site provides no wiring, installation, safety or health instructions.
