  2. Use energy-saving curtains. Get curtains or blinds that block out light and make sure they’re closed at the hottest time of the day. These are also awesome for sleeping since they can really black out a room.
  3. Use ceiling fans, box fans or tower fans. You can learn about the difference of each and the amount of energy they put out here.
  4. Wet towels and freeze them. Place them on the key points on the body, wrists, neck, chest, temples.
  5. Freeze water bottles so you can place them in front of a fan or freeze larger bottles of water to last longer. You can also place these on the key parts of your body, but might need a towel in between or else it could be too cold.
  6. Use an instant pot or slow cooker or eat more salads to limit turning on the stove and oven. Cook outside if possible.
  7. Use cotton sheets and wear cotton clothes. Even better is wearing less clothes.
  8. Get in the habit of turning off lights when you leave a room or when a room is not in use.

What is the Most Energy Efficient Way to use AC

In most cases, understandably, people will still want to use AC and that’s okay too since it’s not realistic to get everyone to not use it. Everything you do will have a carbon footprint so evaluating other areas in your life to make changes can be impactful as well, this article points out the 4 main areas in your life that you can evaluate and make adjustments to help reduce your carbon footprint.

Otherwise, if you still want to use AC, the best thing you can do is optimize it for only when people are home. No need to have it running when the house is empty. Most thermostats have built-in scheduling you can use, but the better way is to use smart technology. Either have it set to automatically run around everyone’s schedule, or control it manually from your phone. This would even be easier when you are out of town or away for longer periods. The same goes for all the electricity in your home too, apply smart technology to lights, fans, etc.! Optimize for use only when people need to actually use it.

Routine Cleaning of HVAC

Set your temperatures to make you comfortable and not overdo it. There’s no reason to set it at 65 degrees daily and end up in long sleeves, long pants, and blankets piled on top of you. Be reasonable. Your body can adapt over time too, so what you’re training your body to do will regulate over time.

The AC unit is the most costly cooling system, so routine maintenance including changing the filter, making sure nothing is blocking the airways, regular cleaning, etc. will ensure it will last a long time.
