CoolVerdict is a free, independent online tool that sizes rooms for air conditioners, estimates running costs, and matches users to window, portable, and mini-split units based on efficiency and price data rather than sponsored placements.
The calculator asks for room size, climate zone, sun exposure, and whether the room is a kitchen. It returns a recommended BTU range (for example, 8,000–9,000 BTU for a 320 ft² room) and links to matched units in the comparison table. Running-cost estimates are based on each unit’s efficiency, about 8 hours of use per day, and average residential electricity rates.
CoolVerdict is free. There is no sign-up required, and the calculator, comparison tools, buying guides, and contractor directory are all available without payment. The site states it has no sponsored rankings; any future affiliate links would be clearly labeled.

They are estimates based on each unit’s efficiency, typical usage of about 8 hours a day, and average residential electricity rates — your actual cost varies with your utility rate and habits. The calculator personalizes it to your room and state.
