Energy Saving & Air Conditioner Efficiency Advice – Tips to ensure you get the maximum benefit from your air conditioner.
- Shut windows and external doors when operating your air conditioner. Close curtains on hot summer days and cold winter nights.
- Minimize the area being cooled or heated by shutting doors to unused rooms – and shut off zones not in use
- Clean filters regularly for unobstructed air flow following the manufacturer’s suggested cleaning cycle
- Position the air conditioner outdoor unit in a shady spot – or create shade for it.
- Ensure good airflow around the outdoor unit
- Set the thermostat of a heated room in winter to between 18-21°C. The temperature of a cooled room in summer should be about 23-26°C (remember the humidity indoors will be low, so it will feel cooler). The temperature should be checked after the air conditioner has been operating for 30 minutes.
- When a hot day is expected, turn on the air conditioner early rather than wait till the building becomes hot (it operates more efficiently when the outside air temperature is cooler).
- If the machine has adjustable louvers, adjust them towards the ceiling when cooling, and towards the floor when heating (as cool air falls, hot air rises).
- Reduce the amount of heat entering the building by shading windows and walls, insulating ceilings and walls and sealing any draughts.
- Open windows and external doors if the outside temperature is lower than the inside temperature, instead of using the air conditioner.
When selecting an air conditioner, look for:
- Programmable timer and thermostat controls. Set your air conditioner at the highest temperature setting at which you still feel cool enough, 25ºC is usually adequate. Each 1°C increase of the thermostat setting will save about 10% on your energy usage
- Movement sensors, which reduce power and energy usage when the room is unoccupied
- ‘Sleep’/quiet’ mode & ‘Turbo’ mode that automatically adjust thermostat settings and fan speed (and associated noise levels)
- The EER (Energy Efficiency Rating)
- Economy settings
- Multi-speed fans
- Fans that can ramp down to as low as 17% (Actron only) when only 1 zone is on.
- Compressors which can ramp down to only 10% of capacity when only 1 zone is on (Actron only)
- Adjustable and rotating louvers (split systems)
- Remote thermostats and controls
- Individual room temperature control (Actron ESP Ultima & ESP Ultima Platinum)
- Inverter technology and the new more energy efficient TRU inverter technology
By selecting the right ducted air conditioner it is possible to save as much as 75% of your air conditioner electricity bill! This is based on real energy modeling comparing traditional fixed speed air conditioners to the Actron ESP Ultima air conditioner that is totally unique.
