Tips and Tricks to reduce your AC’s power consumption

Air conditioners are likely one of the biggest consumers of power at your home or office. What follows below are some easy to follow tips that will help reduce your power consumption while using an AC.

Type of AC: If you are planning to cool 3 or more rooms simultaneously in your home or office, it makes sense in investing in a central air conditioner versus individual window units for each room as central cooling could be more energy efficient. Central air conditioners also do a better job of lowering your room’s humidity if you live in a hot and humid place.

Right Size: Buy an air conditioner that is powerful enough to cool the room that you will install it in. Bigger the room greater the AC tonnage required. The AC size needed also depends on the number of people normally in the room and heat generating sources including sunlight and gadgets affecting the temperature in the room. An AC that is not capable of cooling your room will require a lot more power than a ‘right sized’ air conditioner as it will need to work overtime while attempting to cool the room . However that does not mean that you should over pay for a higher tonnage AC when it’s not needed as it will use more electricity

Energy Efficient models: AC’s are graded by the Indian Bureau of Energy Efficiency using a rating called the BEE rating . A model with a 5 star rating is highly energy efficient and consumes less power than a 4 star model which in turn is better than a 3 star graded unit and so on. Therefore it is advisable to buy an air conditioner with a 5 star rating and thereby save on electricity.

Use Fans along with AC’s: An AC consumes as much as 25 times or more electricity than a ceiling or a table fan will ever consume! Make use of a fan as much as possible to beat the summer heat. This will help in circulating cooled air more efficiently inside the room enabling you to set the thermostat temperature at a higher degree thereby lowering your electricity consumption considerably. If you have a long narrow room with an AC at one end, a table fan can help push the cool air further into the room.

Maintenance of AC filter: Dust and dirt collected in the filter will hamper the free flow of air, possibly even damage the unit. Clean or replace filters regularly . This will not only help the unit to cool down faster but also reduce energy consumption. A sliding filter is easier to clean. The instruction manual accompanying the AC will provide recommendations and guidance on filter maintenance and cleanliness.

Maintenance of outdoor coils: Outdoor coils are constantly exposed to dust . Coils coated with layers of dust and mud will reduce the efficiency of the AC . Keep them clean.

Preventing outside air: Always take extra care to keep the doors and windows of an AC room closed as much as possible. Carefully avoid moist and warmer outside air from entering the air conditioned room since this would result in an increase in electricity consumed by your AC. Remember that the natural air coming through normal leakages in the windows and doors will sufficiently ensure comfort conditions and minimize any unwanted odor in the air conditioned room. Take care to see that the unit is well sealed from the outdoors during installation and routine maintenance .

Maintain an ideal AC thermostat setting: For each degree set above 22 degrees c the AC uses 3 to 4 percent less power. The thermostat set at a temperature of 25-26 degrees c during summer should be comfortable. Lesser the difference between outdoor and indoor temperature lower would be the energy consumed by the AC. When you turn on your AC avoid setting the thermostat at a lower temperature than required. This will result in unnecessary extra power consumption as it will only cool your room to an undesirable lower temperature but not any faster!

Ensure free flow of air: Any objects between the AC and it’s air passage will only hinder its efficiency . Remove any such objects.

Heat generating objects: Electrical gadgets like TV, lamps, computers, modems etc generate heat. Avoid placing them near the AC. The thermostat being sensitive to heat will require the AC to unnecessarily run longer.

Natural cooling techniques: Most of the heat enters your home through the roof. Consider applying a reflective paint coating on the roof to reduce solar absorption. Also consider painting the exterior walls with lighter colors that reflect sunlight. Surrounding your home with trees and shrubs as much as possible is another good natural cooling technique. This will keep your home cooler and therefore reduce the consumption of power by the AC.

Annual maintenance contract: Make use of services provided by a well trained and qualified staff directly from the manufacturers or it’s authorized company. See to it that the technician measures in amperes the total energy drawn by the AC. This will indicate the current used up by the unit. Higher the value greater will be the power consumed.

Replacement of AC: A much older AC that requires major repairs will probably become less efficient . It is then time to replace it with a new energy efficient unit.
