How to Get the Best Cooling From Your AC While Keeping Power Bills Down | 12 Expert Tips
As climate change continues to push temperatures higher, summers are becoming increasingly unbearable. This year, thermometers are already hitting 40°C, leaving many of us reliant on air conditioners for relief. However, ACs can be power-hungry and inconsistent in their cooling performance. The good news? You don’t need to call in expensive professionals to improve your AC’s efficiency. Here are 12 simple, DIY tips to help your air conditioner cool better while saving electricity.
1. Clean the Outdoor Unit
Dusty conditions can clog the cooling fins of your outdoor unit, reducing its heat exchange capacity. Use low-pressure water to clean the fins, but avoid spraying electrical parts or damaging the fins. Always disconnect the unit from the mains before cleaning.
2. Clean the Indoor Unit
Use an AC cleaning spray to remove dust from the indoor unit’s cooling fins. Wash the dust filters under running water, and use an old toothbrush for stubborn dirt. Avoid using water directly on the indoor unit.
3. Ensure Proper Ventilation for the Outdoor Unit
Place your outdoor unit in a well-ventilated area. If it can’t dissipate heat effectively, its cooling efficiency will drop significantly.
4. Set the Optimal Temperature
Aim for a temperature setting between 22°C and 24°C. This range ensures comfort without overworking your AC. Avoid setting the temperature below 22°C.
5. Avoid Frequent On/Off Cycling
ACs aren’t designed to be turned on and off like fans. Frequent cycling strains the system. If you’ll be back in the room within an hour, leave the AC running.
6. Precool the Room
During peak summer, let your AC run continuously for the first 24 hours to cool everything in the room—walls, furniture, and more. Once the room is cooled, maintaining the temperature requires far less power.
7. Use a Ceiling Fan
Pair your AC with a ceiling fan set to low speed. This helps distribute cool air evenly, reducing the load on your AC.
8. Block Sunlight with Curtains
Sunlight streaming through windows heats up the room. Use heavy curtains to keep the heat out and maintain a cooler indoor environment.
9. Check for Air Leaks
Inspect windows and doors for gaps. Cold air escaping through leaks reduces your AC’s effectiveness. Seal any gaps immediately.
10. Install a Door Closer
A door closer ensures the room door doesn’t accidentally stay open, preventing cool air from escaping.
11. Avoid Heat-Generating Appliances
Steer clear of using hot appliances like toasters, ovens, or refrigerators in an air-conditioned room. They generate residual heat, making your AC work harder.
12. Limit Electronic Devices
Turn off TVs, computers, and other electronics when not in use. They produce heat, which can increase the room’s temperature.
By following these tips, you can enjoy better cooling performance from your AC while keeping your electricity bills in check. Stay cool and comfortable this summer!
