Especially welcome:
- Model number corrections — if the decoder misreads your unit, send the model number, brand and the tonnage from the data plate.
- Tariff and rating updates — BEE star bands and electricity tariffs change; pointers to current official tables help keep estimates honest.
- Calculation disputes — if a result looks wrong, include your inputs so it can be reproduced.
This is an independent site; we don't sell, install or recommend specific AC brands, and we don't answer purchase-advice emails individually — the guides cover the honest tradeoffs.
