Set Your Thermostat Right to Save Money and Energy

In 2019, large parts of the country witnessed harsh temperatures that lasted throughout the summer months. Many areas saw the mercury close up to the 50 degree Celsius mark, with Delhi at 48-degree celsius, Banda in Uttar Pradesh at 49.2-degree celsius, and Churu in Rajasthan at 50-degree celsius.

In order to combat this heat, one of the most effective solutions is to use an air-conditioner. However, it is important to understand that the incessant use of air-conditioners will have an impact on the monthly electricity bills. While using the AC is unavoidable in some circumstances, garnering a big bill is not. Read on to know more about how the right temperature setting on your thermostat can save both money and energy. 

How it Works

An air conditioner works by pulling in the warm air in the room and passing it through the evaporator-coil. The now-cooled air is then passed out into the room. This process is repeated until the room achieves the desired temperature. 

The compressor works throughout the cooling process. In a non-inverter AC, once the desired temperature is achieved, it switches off, leaving only the AC fan running to maintain circulation. When the temperature begins rising again, the compressor too begins working to bring it back to the desired level. 

Now, assuming the average outside temperature on a given summer day is about 38-degree Celsius, the amount of work done by the AC compressor will depend on the desired temperature. If the desired temperature is 25-degree Celsius, the AC will have to expend less energy to cover that gap. If the room is required to be at 18-degree celsius, the AC will have to work that much longer and harder to, both, achieve and maintain that lower temperature. 

This means that the lower the temperature requirement, the more the energy usage by the AC. Concurrently, more the electricity bill garnered at the end of the month. 

What to do

Having ambient temperature in the room and preventing a high electricity bill are not necessarily inimical to one another. By setting the thermostat to the right level, optimal and economical cooling can be achieved. The right thermostat settings would, of course, differ depending on the season. 

For the summer months, the ideal temperature for the thermostat would be at approximately 25.5-degree Celsius. This is the ideal temperature because not only does it ensure that the room is cool and comfortable for its occupants, it is also not so low as to require the AC compressor to work harder to achieve and maintain that temperature. Setting your thermostat a tad higher won’t make much of a difference to you. However, that difference will definitely be reflected in your electricity bill. 

In addition, following simple practices like turning on the fan to increase circulation, drawing the curtains to prevent the heat from entering through the windows, and taking an afternoon shower can go a long way in facilitating faster and more efficient cooling. 

Conclusion

Setting the thermostat at the right level helps ensure both efficient cooling and money-saving. In fact, off-setting the window AC price or the split AC price can also be achieved by setting the thermostat to the right level, thus saving on electricity over time.
