Close all doors and windows – This will stop non-air conditioned air, whether hot or cold, from flowing into the room, as well as stop your air conditioner from running for longer.

Keep the area you’re cooling or heating to a minimum – You can do this by closing the doors of other rooms that don’t require cooling or heating. You can also make sure that vents and thermostats in unused areas are sectioned off.

Check the difference between the indoor and outdoor temperatures – Whatever the temperature is outside, don’t cool down the room’s temperature to less than 8°C below it. Also, the smaller the difference between the inside and outside temperatures, the lower your cooling costs will be. Do this by setting your thermostat at a high, comfortable temperature in summer and ensuring humidity control if required.

Adjust the temperature depending on the season – Set your thermostat between 24-26°C in summer and 18-20°C in winter. For rooms that are used infrequently (e.g. toilets and storerooms), the temperature should be 16°C in winter.

Don’t set your thermostat at a colder temperature than normal – Your home will not cool down any faster and can result in overcooling.

Use the economy mode – This will reduce energy usage by maintaining moderate temperatures in the right conditions.

If you have a central cooling system, use the zoning options – This will allow air to flow to only certain areas of the house.

If you have a central air system, have the fan shut off together with the compressor – Set the ‘auto’ mode on the fan setting to do this and use fans in individual rooms instead.

Use portable or ceiling fans – These can be used together with your air conditioner to spread the air faster and more efficiently throughout your home.

Ventilate at night or early in the morning – Close the windows during the day and open them at night or in the early morning to let in some fresh air.

Turn it off when the temperature outside drops – You can then let the cool air inside by opening the doors and windows.

Turn off other internal heat sources – These include lights, computers, printers and ovens. They can add to the heating load, so turn them off when not in use.

We Use energy-efficient lighting and office equipment – They will not emit as much heat as less-efficient products. For lighting, use compact fluorescent light bulbs.

Only use it when needed – Your air conditioner should only run when you’re using the room. For commercial buildings, it should be turned off at the end of the business day and on the weekends.

Use timers – You can reduce the number of hours the air conditioning system runs for by using timers. The system will switch on when someone enters the room and switch off when they leave the room.

Use a programmable thermostat – This is great for commercial buildings, as it’ll turn on the air conditioning system 30 minutes before people arrive and turn it off 30 minutes before they leave at the end of the day.

Ensure good air circulation around the inside and outside units – Remove curtains, furniture or plants that may be blocking the inside unit, and also clean the filter. For the outside unit, remove dust that may be blocking the heat exchanger, as well as plants that are obstructing the airflow.

Cover the outside unit from the sun – Use an awning or a shade mesh to ensure that the unit doesn’t overheat.

Don’t confuse the temperature sensors and thermostat – If there are other heat sources near the air conditioner, such as a lamp or TV, place them somewhere else so as not to influence the sensors on the wall or unit, as well as the thermostat.

Don’t do things that will increase the room’s humidity – Don’t have a long hot shower, mop the floor or dry the clothes. Only do these things in the evening when it’s cooler.

Make sure ducting is free of air leaks – Cool air that escapes will cool the inside of your roof rather than the inside of your home.
