With summer officially around the corner and temperatures edging higher, we've put together a giant list of ways to keep your cool.
 
We'll start with a quick apology to our readers in the Southern Hemisphere: We know you're there. Bookmark this and read it again in six months — but you'll find some general energy tips here which work as well during the winter as they do all summer long.
 
Energy isn't cheap, and it looks as if this year will set some record prices. Power generation means more toxins and greenhouse gases released into the atmosphere. So keep yourself cool while saving money — and the environment!
 
The little things
This set of ideas costs nothing to implement. Most are just a matter of thoughtful energy habits. Since none of these involve capital improvements, they're renter-friendly.
 
• Set your thermostat to 78. Go higher, if the humidity is low enough and you feel comfortable. Turning a thermostat down to cool a room quicker doesn't work, by the way — it makes the A/C run longer, not colder.
• Wear short-sleeved, loose clothing. You dress lightly to go out on a summer day. Do the same indoors. Absorbent, wickable cotton (organic, of course!) is the hot weather classic.
• Drink lots of water. This is good practice, anyway. Cold drinks drop your body's core temperature and cool you down quickly.
• Draw your drapes. Keeping your blinds, shades and curtains closed — particularly on the west side of the house — helps keeps heat from getting inside in the first place.
• Turn off unnecessary heat-producing devices. Incandescent light bulbs are a big heat generator. Shut down electronic gear when you're not using it.
• Use the microwave. Conventional cooking dumps heat in the house, but microwaves cook the food directly.
• Wash and dry clothes when the day is cool. Do laundry early in the day and late at night. Don't forget clotheslines: they generate no heat in the house.
• Skip your dishwasher's dry cycle. Rack your dishes and let them air dry instead.
• Open the bathroom window when showering. Vent heat and humidity outside, rather than back into the house. Obviously, you don't want to put on a show for the neighbors. If you have privacy concerns, open up after dressing. Keep the bathroom door closed.
• Run your air conditioner fan on low. This is particularly helpful in areas with high summer humidity. The low air volume helps your A/C dehumidify.
• Keep heat-producers away from your thermostat. Don't allow a closely located TV or water heater to convince your thermostat that it's hotter than it really is.
• Check your refrigerator settings. The fridge takes heat out of your food and transfers it to your kitchen, so be sure you're running efficiently. The refrigerator is best set between 37 and 40 degrees Fahrenheit. Put the freezer around five degrees.
• Turn off your furnace pilot light. You can always re-light it next autumn.
• Close the fireplace damper. Don't send cool air up the chimney. If your fireplace has a glass door, shut it.
 
Small projects
These are all relatively inexpensive things you can do to keep your cooling costs and summertime energy use down. Most will pay off in savings from season to season.
 
• Install ceiling fans. If you're a mammal, you're surrounded by a small envelope of body heat. Fans move this heat away from you and provide evaporative cooling as you sweat. If you choose fans with lights, look for the kind with dedicated (pin-type) CFLs. It's also smart to have a few portable fans you can move around the house.
• Replace your air conditioning filters. Clean filters in window units. You should do this every month, so keep a stock of filters on hand.
• Buy a dehumidifier. ENERGY STAR says a 40-pint unit will save up to $20 USD a year and last up to a decade. Moderating your home's humidity — in addition to making you feel cooler — will reduce musty smells and the growth of harmful molds.
• Shade your air conditioner. If your A/C is in full sun, it's working harder than it needs to. Don't obstruct the air flow.
• Have your air conditioner serviced. Coolant levels should be checked every year. A professional also will clean and lubricate the system. Without annual service, your air conditioner will lose about five percent efficiency each year — more if the coolant is low. Use Puron or some other non-CFC coolant, rather than environmentally harmful freon.
• Check your weather stripping. Caulk leaky window frames, while you're at it. This also will suppress drafts in the winter. If you have a window-mounted air conditioner, be sure the accordion seal is tight. Add rubber gaskets to wall and light switches to make sure the wall is sealed.
• Insulate interior hot water pipes. No point heating your room air and the water. If it's indoors, wrap your electric hot water heater with an approved insulator. Gas heaters should be insulated by professionals.
 
The big stuff
Here are some big-ticket items appropriate for homeowners committed to long-term energy savings. The more you do, the more you save!
 
• Upgrade your attic insulation. Most experts recommend 10-17 inches of R38. You have a lot of options in this area, so it pays to consult with a professional.
• Improve attic ventilation. It can get up to 140 degrees in your attic during the summer. Adding an electric fan or wind turbines will move some of this unwanted heat away from your living space.
• Plant deciduous trees on the west side of your home. You're looking for fast-growing shade trees to keep the hottest part of your house cool during the summer months. They'll lose their leaves each autumn, letting sunshine through once it turns cool. Opt for lightweight trees in areas prone to hurricanes and winter ice storms.
• Replace gas appliances with efficient electric units. Pilot lights contribute to indoor heating, and electric prices are generally more stable than natural gas.
• Replace older windows with new, energy-efficient units. The U.S. Department of Energy says this is the best bet for improving year-round home energy efficiency. Modern units feature advanced coatings to keep cooling and heat where you want it. If you're on a tight budget, consider interior or exterior storm windows to beef-up your current installation.
• Upgrade older air conditioners. Another expensive item, but cooling can account for half of your summer energy bill. You're looking for a unit with a Seasonal Energy Efficiency Ration (SEER) of 13 or more. The best deals are obviously found off-season, but this is one investment which will immediately return savings.
 
Now it's your turn. Got any tips on staying cool through the summer months? Big or small, please share them in our comments section!

OOPS on vinyl windows



I meant to say, most vinyl windows off gas rather than NO vinyl windows off gas.

Don't assume new windows are greener



No vinyl windows off gas. Old wood ones don't. Trashing old painted windows generates lead dust when you remove them if your house is older than 1978. Reglazed and weatherstripped old windows especially with wooden storm windows can be as efficient as new ones. Consider the waste fill of old windows. Now that's not green. If you end up deciding to do so, donate them to Habitat for Humanity or a Recycle/Rebuild facility.

Where the Mother Are You?



Well most of these suggestions are useless to me. I don't have an air conditioner nor a pilot light nor a dish washer, thermostat, fireplace,, clothes dryer,

Aircon vs ventilation



If you live in a dry-heat environment consider evaporative air conditioning as it is much less energy intensive than the usual refrigerated models (which are excellent for humid heat) and they can be very effective. They are very popular in Australia for instance.

Also, pay close attention to the outside temps. When they drop below the indoor temp, don't be afraid to open your windows a bit even if the aircon is on as it will help the appliance by letting some of the heat out. This is,.... More

Cool Customer



All grammar aside, I'd like to see MNN investigate the gas appliances vs. electric appliances issue. Perhaps another post would be good. I've found gas appliances to be more energy efficient than electric, even with a pilot light and the potential price changes for natural gas.
I must agree with the window advice. In our old Victorian home, window replacement was worth every penny. We bought custom windows for our old Victorian home, and the insulation value is tremendous all year. .... More

Another good idea



Dry ice works well as a cool media.

Take anti-freeze in a bucket, add the dry ice, place inside a milk crate, and put a box fan on top of the milk crate blowing down. The Carbon Dioxide won't have time to build up to harmful levels, and your house will stay cooler.

Use a fan with your AC



I live in Bangkok, Thailand where is is hot and humid every day. The Thai people think that I am crazy because I use a portable fan even when I open my AC. But there is a method to my madness. First of all the trick to staying cool is air movement. And the fan in your AC is not designed to move air efficiently. It is much too small. So I use a fan to move the air in my apartment. As a consequence I never ever set my A|C lower than 28 degrees Centigrade. The AC does its job by taking the.... More

It's all that about idiots or about staying cool in Summer?



Please concentrate and comment on the subject and stop insulting people who have a diferent oppinion as your's. That's democracy

we were learning about what?



I thought this was about cooling down in the summer, not grammar lessons...

Really!



You shouldn't go around calling people idiots. We try to keep our home as cool as possible but we cant afford a high monthly bill. I'd love to keep my house at 76 but we keep it at 85. We also use fans. You get used to it and its actually not that bad unless you've been at the mall where the air is freezing! We also have a baby and it's not healthy to keep the house too cold or too hot. Everyone's body temp is different and some people can deal with a little hotter weather than others but it.... More

help stay cool



In the summer. I put window tent on all windows, on the west side of my house. This helps alot.Then in the Fall take it off. Roll it up, for next year. put away. It doesn't cost much money to do this. .... I have a window unit. and it is in the wall on the west side. What can I do to shade it, without costing much?

Shade



You could try installing an awning above the window unit. We live in East-Cental Alabama where it stays hot and humid during the Summer. A couple of year ago, we put awnings on all of the windows...could not believe how much that helped.

P.S. To "People who live in glass.....".



To Jamie:
In addition, you misquote your quote. It should have a quotation mark and an ellipsis after "You're...." and also before "You" in "You are an idiot." The "or" in the sentence should not be within the quotation marks because it is NOT part of the quote.

Get it?

showers



ive noticed when i take a hotter shower in the hot months, (i know, sounds icky) my body produces less heat and im cooler the rest of the day. i work in retail and everyone else has a fan running. when i take a colder shower, i need that fan on. just something to consider.

I'll pay xtra to stal cool



I have done most of these things on the list, but i will not set the temp at 78. I like it between 68-70. I work hard for a living and don't mind paying the extra to stay cool. If you think about it most people have their house at this temp in the winter & it's ok. So that's my year around temp. Just adding my two cents:-)

correction



i meant to say I'll pay xtra to stay cool...oops

Awsome!!!!!!!!!



I love this, it is so cool, and speaking of cool, yeah, it is cool!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

be care about trees



I did plant quick growing deciduous trees/bamboo on the west side of my home and they were really taking off especially the one that was unknowingly planted over my sewer line. This hybrid poplar grew over 20 feet in less than 18 months but obviously I had to get rid of it or risk the roots getting into the sewer line. So warning..before planting fast growing deciduous trees notorious for invasive roots check and make sure your familiar with the septic/sewer lines. I don't know what a safe.... More

cheap air conditioning



When I have an oven on or the air conditioner just isn't working for the hot and cranky kids. I will turn a fan on with a bowl of ice in front of it and the kids feel cool as cucumbers.

your an idiot!!!!!



You are one of the people that are like my buddy who is half mexican and can be comfortable in 80 degree weather even sleeping under covers.... I will tell you this, even when the humidity is low and its cool outside I still have to have the air on 72 degrees so that its even nice to be under cover and not sweating to death... If you are cold natured then you are on coumadin or a blood thinner or just getting old with thin blood and this isn't natural and it should concern you!!! You can put.... More

Jesus Christ



Jamie, not everyone who is cold natured are old or on blood thinners. My children are 1 and 2 and are cold natured. Explain that one to me. I don't give them aspirin because it's a blood thinner. They're certainly not old. Another thing, keeping the air set higher lowers the electric bill. Yes, I'm a little warmer than I would like to be but I can at least afford to pay my light bill, even on a limited income. Get over yourself. Some people have different temperature tolerance than others do..... More

Grammar



You're*

Your??



Try "You're or You are an idiot" You look like an idiot that doesn't know proper grammer

"You're an idiot"



To Jamie: "People who live in glass houses shouldn't throw stones".
1. "an idiot THAT doesn't ...." The correct relative pronoun is 'who' since you are speaking about a human being who is an idiot. Also, 'who' is preferable because "know" is only an action that a human can take.

2. GrammER should be grammAR.

You're living in a glass house.

That's correct...



It would be "you're an idiot." Haha, you idiot! :)

:)



You made my day :)

GeoThermal



I built a home in 2006 and installed geothermal heating/cooling. WOW, was that ever the right thing to do! It's GREEN, quiet, and my monthly bills are quite low year round! I don't have a noisy outdoor unit that needs to be shaded from the sun or protected from damage.

I also used foam insulation in addition to fiberglass batting. When it's windy outdoors, I can't even tell. It provides quiet and more savings every month in my heating and cooling bills.

Why have a jacuzzi or.... More

geothermal installation



Hello Geothermal. Who does this geothermal installation? can this system be installed in an older home? Thanks.

Older Homes w/ Geothermal



I own my family homestead (140 yrs old) & my parents installed geothermal back in the mid 90's. It works quite well in an older home. To make it more efficient, be sure to upgrade your insulation & check for draft areas.

Many larger towns have geothermal installers listed in the phone book. You can also look online to see if there is one near you. I'm thrilled my parents did this & I think you could enjoy it as well.
