10 ways to cut your cooling costs

Temperatures are on the rise, and so are electricity and fuel costs, making it harder to keep our cool. That doesn't mean your home has to become unbearably hot, though. Here are 10 ways to reduce your cooling costs this summer.

  1. Use a programmable thermostat to adjust the temperature automatically when you're not home. According to the folks at Energy Star, the average U.S. household spends about $1,100 heating and cooling costs. A properly set programmable thermostat can save about $180 a year. (Not sure how to set yours? Here are some guidelines.)
  2. Set the air conditioning to kick in at 80 degrees instead of 78 degrees (or even higher, if you can stand it). That tiny two-degree difference can shave 2 to 6 percent off of your electricity bill, depending on the size of your home and how long you keep the AC on.
  3. Seal off AC ducts in unused rooms so you don't spend money cooling them. Why keep the guest room at a comfy 80 degrees -- I mean 78 degrees -- if no one's there?
  4. Don't use the AC at all. Fans use less energy than air conditioning units; they keep you cool by moving the air around, though they don't actually change the temperature in the room. If you can't bear to live without air conditioning, consider using a fan at the same time so you'll feel comfortable even with the AC set at a higher temperature.
  5. Draw the curtains and blinds on your south, east, and west windows to keep sunlight from warming the rooms during the day. If you still want the light, but are worried about the heat, try applying heat-control window film to the glass -- it blocks UV rays and reflects back much of the heat.
  6. Wash clothes in cold water. If you're still worried about germs, use warm water for the wash and switch the rinse water to cold -- you'll save up to 4 percent on your energy bill, and your clothes will be just as clean. If you have the space and the time, try hanging your clothes up to dry instead of using the drier -- it'll lop another 5 percent or so off your bill.
  7. Cook outdoors on the grill (or opt for salads and don't cook at all) to keep the heat out of the kitchen. Can't cook outside? Cook in the microwave; it uses about 65 percent less energy than your stove. (Still not sure what to make? Here are a few easy summer recipes that won't leave your roasting in the kitchen.)
  8. Upgrade to more-efficient appliances. It costs more now, but you'll save money over time.
  9. Plant trees to shade your house (and your AC unit). According to researchers at Colorado State University, a tree in full leaf can block 70 to 90 percent of solar radiation. You can also plant trees and shrubs to create a wind-tunnel effect, channeling breezes into your house.
  10. Take a shower using a minty body wash (Dr. Bronner's Peppermint Liquid Soap is a classic) to make warm air feel like a cool breeze on your skin. OK, fine, you can't necessarily jump in the shower several times a day. Try holding an ice pack to the back of your neck; it lowers your body temperature by cooling the blood as it pumps through your carotid arteries.

    Here's a trick I discovered in my pitiful grad school days, when I survived Chicago heat waves with NO AC! It was awful, but I found combing plenty of water through my hair every so often really cooled me down. Your hair can hold a LOT more cooling water and takes much longer to evaporate than water on your bare skin.

    sitting a bowl of ice in front of a fan makes it feel like air conditioning!

    I have 1205 sq ft in a mobil home in Texas. I keep the thermostat at 85 degrees. I don't use two rooms and have the vents blocked, ceiling fans are non stop, floor fans also move air around. I make sure the a/c is at 90 when I leave for the day, with the fans blowing it isn't half bad. July bill $127.00.

    What I do is turn my furnace fan on for about 10 or 15 min.to drawl out the cool air from the basement just before I go to bed.

    I put a fan on during the morning hours and the a.c. is for late afternoon depending on how "hot" it gets and during sleep hours. Where I live on a top floor windows facing direct sunlight from 2:00pm till 8:00pm it becomes sweltering. I draw my shades and curtains in the afternoon hours when the sun starts to pour in. It does help as well as do all my chores in the morning hours.

    Milton~ Lol, many of us are unemployed living on a single income not by choice btw... Those fortunate to be working need to watch their spending because nothing is secure at this point in time. Conserving doesn't mean - we can't or choose to roast and find alternative ways to keep cool. For me and I believe others it means saving money - no one knows for certain what tomorrow might bring. I'd rather be comfortable knowing I have some money saved for other more important necessities (like shelter and food.) Btw... If our ancestors did it so can we.

    Well, well, well...sometimes it's hot, sometimes it's not. I just try to do what I can every day to be comfortable. Join "The King of Glory Movement" as we seek to evangelize the world, one soul at a time. It could be eternally hot when you have no salvation in Jesus Christ.

    78 is comfortable? No way. Our AC stays at 69 when we are home, and I set it to 80 when we are at work and leave our fans on.

    I live in a place that gets to 110 on summer days. SO, on days when event the AC isn't enough, I fill the tub with cold water, put my feet in (my whole body is too much!), and dip my wrists in too and it works like a charm to cool me down. if you cool off your pressure points, it cools your whole body.
