When it comes to saving money on cooling your house, you have plenty of options. Here are 23 to choose from.

  1. Leaving your curtains, drapes and shades open all day allows solar heat to enter your home. Close them whenever possible.

  2. Even better than shades on the inside are awnings on the outside. Install awnings or overhanging shades outside your windows.

  3. Why pay to cool storage spaces or spare bedrooms? Close unused spaces off from the rest of the house.

  4. There's no point getting in the way of your air conditioning vents. Clear any furniture or hanging objects away from the vents so the air can get out.

  5. Some of the best cooling aids are completely natural. Cultivate shade trees and shrubs around your home, especially on the sunny sides.

  6. Holes and leaks can allow warm air to seep into your home. Seal them up tightly.

  7. Vents and pipes that enter your house from outside are sometimes improperly sealed. Check them all and use caulking to correct any problems.

  8. A chimney can let warm air into your house if not tightly sealed. Fill any gaps and holes you find around your chimney.

  9. Ceiling fans let you turn down your air conditioner a few degrees while staying just as cool. Make sure you choose energy efficient ceiling fans, and turn them off when you're not in the room.

  10. Dark colors absorb heat. Paint your roof white or install a “green roof” with vegetation.

  11. A poorly ventilated attic can increase the temperature of your home. Check that you have vents in your eaves, allowing cool air to blow in. You could also consider buying an attic fan.

  12. Windows absorb heat. Put reflective window tint on the glass to minimize this effect.

  13. A window air conditioning unit that is too large for the room uses more energy, costing you more. Choose a unit that's the right size for the space.

  14. Your cooling system may be costing you money if it's not performing well. Hire a professional to perform maintenance once a year.

  15. There's no reason to cool down an empty house while you're at work. Install a thermostat that you can program.

  16. Cooking on your stovetop or using the oven generates heat inside your house. Instead, use an outdoor barbecue grill or cook during the cooler part of the day.

  17. Dishwashers generate heat when they're being used. Run your dishwasher at night to avoid making your house hotter during the day.

  18. Air conditioning condensers don't work as well if they're in bright sunlight or crammed into a small space. Put your condenser in a shady, spacious area.

  19. Ordinary incandescent light bulbs produce heat. Turn off all lights when you're not in the room, or replace them with CFLs.

  20. Laptops, battery chargers, TVs and other electronic items use electricity even when you're not using them. Plus, they generate heat. Unplug them when you're not using them.

  21. Central air conditioning systems are assigned seasonal energy efficiency ratios, also known as SEER numbers. Look for a SEER number of at least 13 when buying an air conditioner.

  22. Room air conditioners are assigned energy efficiency ratios (EERs). The higher the number, the more expensive the unit, but it could save you money in the long term if you live in a very warm climate. Choose an EER that fits your climate and budget.

  23. Air conditioning unit filters work less efficiently after about a month. Change your filters every month when in constant use.
