Aircon Running Cost Calculator
Estimate how much your aircon costs to run each night or month, based on the rooms you actually use, BTU, tick rating, usage hours, and Singapore electricity tariff.
Estimate the running cost
Start with the installed system, then choose how many indoor units are usually running. The estimate is based on active rooms, not the label System 3 or System 4 by itself.
How to use the estimate
The number gives you a baseline for aircon usage. If the estimate is close to your bill increase, the cost is probably usage-driven. If your bill jumped far beyond the estimate, the next step is to check airflow, sizing, outdoor-unit ventilation, and cooling performance rather than guessing.

Bill looks too high?
Send the estimate with your room, usage, and bill jump. We can help separate normal running cost from a cooling-efficiency problem.
