As summer approaches, many have already started using air conditioners (ACs) to beat the heat. However, the rising electricity bills at the end of the month often leave people worried. The size of the room plays a crucial role in determining which AC to buy. Experts recommend purchasing a 1.5-ton AC for larger rooms. But how much will it cost if you run a 1.5-ton AC for 10 hours daily? Let’s break it down.

Modern inverter ACs are designed to cool rooms quickly and then adjust their compressor speed to save energy. For instance, a 1.5-ton inverter AC typically consumes around 700 watts in the first hour, 500 watts over the next four hours, and about 200 watts for the remaining hours. Assuming an average usage of 10 hours per day for 30 days, the monthly consumption could be approximately 99 units. At a rate of 7.50 taka per unit, the bill would come to around 742.50 taka. However, this can vary depending on external temperatures and usage patterns.

On the other hand, older non-inverter ACs consume significantly more power, ranging from 2,000 to 2,500 watts per hour. Running such an AC for 10 hours daily could result in a monthly bill of 4,500 to 5,500 taka. To save costs, experts suggest opting for inverter ACs, maintaining a temperature of 24-26°C, and regularly cleaning the filters. Keeping doors and windows closed while reducing nighttime usage can also help lower electricity bills. By choosing the right technology and adopting energy-saving habits, you can enjoy comfort without breaking the bank.
