Keeping Cool This Summer



1. Open Your Windows

When the outside air is cooler than the inside, it’s foolish to keep using electricity for something nature can do for you instead.

Nothing is more satisfying than getting a breeze of fresh air after having your home closed up all day.

2. Turn On the Ceiling Fans

While a ceiling fan won’t make your room cooler, it will definitely make it feel cooler by speeding sweat evaporation and fans cost far less to run than your air conditioner. Ceiling fans are relatively easy to install if you do not have them. Once your fans are in, make sure the fan is set to spin in the correct direction: You want the air blowing down in summer and up in winter.

3. Put In an Attic Fan

An attic fan gives you the combined benefits of moving air (like a ceiling fan) and pulling in the cooler air from outside. Of course you need to open your windows to pull in the cooler air so it is best to wait until after dusk to open your windows and then set the timer to run at least until after you’re deep asleep. It’s an investment that can easily pay for itself in a couple of years. Solar powered attic fans are also available.

4. Shut the Blinds

On hot summer days, the sun is your worst enemy. The last thing you want to do is have your air conditioner running full blast to offset the increase heat from the sunlight pouring in your windows. By closing the blinds, you’ll still let in enough light to see by, but you’ll reflect back the rest.

5. Run Your Furnace Fan

Many thermostats will allow you to tell the fan to run without initiating the furnace or air conditioner. By turning on your furnace fan, you cause the air to be circulated throughout the house, balancing out any cold or hot spots so that you whole house feels more comfortable. An added benefit is that it will trap any potential allergens that have been introduced by opening your windows - just make sure to regularly check the furnace filter and replace it when it’s dark enough to block light passing through.

6. Install a Programmable Thermostat

It doesn’t make much sense to cool your home while you’re gone, but it’s hard to remember to tweak your thermostat every day before you leave for work. Program your thermostat to go up by five degrees about 30 minutes or so before you leave and have it come back to your “normal” temperature a half-hour before you return. For added savings, program it to also raise the thermostat by two or three degrees through the night - you’re unlikely to notice the change in your sleep.



7. Turn Up The Thermostat A Degree Or Two

It’s recommended that you set your thermostat at 78 degrees during the summer if you have central air conditioning. It’s a pleasant temperature, but isn’t necessarily the cheapest setting. If you can handle it, raise your thermostat by one or two degrees and realize a savings of about six to seven percent for each degree above 78.

8. Close Unused Vents

If you’re not going to be in a particular room very much or very often, consider closing the vent in that room so you’re not cooling dead space. That will cause more air to come out of the other open vents, potentially allowing you to add some cooling to a room that wasn’t getting it otherwise.

9. Turn Off the Lights

The light filtering in through your closed blinds should be sufficient to get you around the house during the day. When night falls, turn on only the lights you need only when you need them. Not only will you save electricity, but you’ll also do your air conditioner a favor. All light bulbs generate heat as a byproduct of producing light. Use Compact Fluorescent Light bulbs (CFLs) inside. CFLs use 75% less energy and produce 75% less heat than incandescent light bulbs which saves on cooling costs.

10. Hold Off On Cooking

During the summer, do what you can to avoid turning on the stove and, if you must turn it on, turn it on in the late evening and after you’ve opened the windows for the night.

11. Leave Laundry Until Nighttime

Your clothes dryer puts out a decent amount of heat. Much of that heat will be vented outside, but some will still leak into your house. The later you wait to turn it on, the better chance you have of not working against your air conditioner as much. If you live somewhere that has time-based metering of electricity, try to wait until the lower evening rate kicks in.

Of course, nothing beats line-drying in terms of electricity usage, but if your subdivision bans outdoor clothes lines, running your dryer at night is the next best option.

12. Use Your Lowest Level

If you have a basement, don’t hesitate to take advantage of its stable temperatures all year – The higher you go in your house the higher the temperature.

13. Unplug/Switch Off Unused Electronics

Not only are unused electronics eating electricity when they’re not in use, they’re also converting some of that power into heat. By unplugging everything you can and putting the rest on switchable surge protectors, you can potentially save yourself a lot of money and unnecessary heat.
