AC Tonnage Calculator
Estimate ideal AC capacity from room area, ceiling height, sunlight exposure, and occupant count with practical room AC and multi-unit guidance.
সূত্র ব্যাখ্যা
Required tons = area / 150 + height adjustment + sunlight adjustment + occupant adjustmentA practical AC sizing estimate starts from room area and adjusts upward for higher ceilings, direct sunlight, and extra occupants.
Step-by-Step Example
- 1Estimate base tonnage as room area divided by about 150 sq ft per ton.
- 2Add capacity for ceiling height above 10 ft because the room has more air volume.
- 3Add or reduce capacity based on sunlight exposure and heat gain.
- 4Add a small occupant load for each person above two and map the result to practical 1.0, 1.5, 2.0, 3.0, 4.0, or 5.0 ton guidance.

সাধারণ প্রশ্ন
A quick estimate is about 1 ton per 150 sq ft, adjusted for ceiling height, sunlight, insulation, and occupancy.
Yes. Direct sunlight increases cooling load, so west-facing or poorly shaded rooms often need more capacity.
Yes. Oversized ACs can short-cycle, cool unevenly, and remove less humidity, so sizing should be practical rather than simply larger.
No. It is a practical estimate. Large rooms, top floors, glass walls, and commercial spaces benefit from professional load calculation.
