Energy Saving Tips fpr Air Conditoners

1. Use ceiling or table fan as first line of defence against summer heat, as running cost of using an AC could be 25 times or more than that of a ceiling fan. 

2. Keep windows and doors of air-conditioned rooms closed as often as possible.

3. Avoid outside air intake: Since outdoor air is warmer and contains more heat and moisture than the conditioned air and thus it increases electricity consumption. Keep in mind that natural leakage through windows and doors will generally supply sufficient outdoor air for assuring comfort conditions and minimizing odor.

4. Remove obstructions (e.g., furniture, piled books, etc.) to air passage to the unit. AC operates most efficiently when intake and discharge airflows are free from nearby obstacles.

5. 

   Set AC thermostat settings properly: AC uses 3 to 5 percent less energy for each degree set above 22°C, therefore set AC’s thermostat at a temperature as high as is comfortably possible (25 - 26°C) in the summer. Smaller the difference between the indoor and outdoor temperatures, lower will be the electricity consumption.

6. Consider using an interior ceiling fan in conjunction with your AC to spread the cooled air more effectively within the room. Using fan allows you to set the thermostat temperature higher and thus reduces the energy consumption.

7. Do not set your thermostat at a colder setting than normally needed when you turn on your air conditioner; it does not cool your room any faster and could result in excessive cooling and unnecessary expense.

8. Do not place lamps, televisions or other electric appliances near AC. As these appliances generate heat, and the thermostat senses heat from these appliances causing the air conditioner to run longer than necessary.

9. Plant trees and shrubs to keep the day’s hottest sun off your house, wherever possible. This will reduce energy consumption in AC.

10. Clean the air-conditioner filter regularly: A dirty air filter reduces airflow and may damage the unit. Clean filters enable the unit to cool down quickly and use lesser energy. A filter that slides out easily facilitates easier cleaning. Follow the manual’s instructions for removal and cleaning of filter.

11. Clean outdoor coils when they become dusty. Efficiency of AC degrades in dusty conditions, and especially when layers of dirt and mud are evident.

12. Make sure upon installation and routine maintenance that the unit is well-sealed from the outdoors.

13. Give the annual maintenance contract of AC directly to the manufacturer or its authorized
