Which cassette AC is best, and how much area can it cool?
Our real cassette models range from 1.42 to 3.98 TR — sort by ISEER to find the most efficient option at your needed capacity, the same principle as split ACs. For area coverage, treat TR similarly to split AC tonnage: bigger TR covers more area, but the right size depends on your specific room's heat load, not floor area alone.
📐 Calculated estimate
Based on real BEE-certified data — see the exact numbers below.
We don't have a dedicated cassette-specific area calculator the way we do for split ACs (our Tonnage Calculator is calibrated for residential split-AC use, not commercial cassette sizing) — for an accurate commercial capacity recommendation, that's worth confirming with a dealer who can account for occupancy, equipment heat load, and ceiling height specific to your commercial space.
