Plano Homes : Tips to keep your home cool this summer
Well it looks like the God’s of summer have blessed us with yet another 100 degree day in the Lone Star state. They say after living in Texas for a while that you get used to the heat, and while that may be true, I don’t know that I will ever learn to actually LIKE the heat. And with these high temperatures comes the unfortunate reality of rising electric bills. When I hear my AC running at home all I am really hearing is money leaving my wallet and heading down the street to the big energy company. However there are some tips you can folllow that can not only keep your house cooler this summer but can also save you some real money in the process. I found these tips on a website called Care2.com so I want to make sure I give them the proper credit. Make sure you check their website for some other great articles about healthy and green living.
TIPS TO KEEP YOUR HOME COOL :
1. Reduce the cooling load by employing cost-effective conservation measures. Provide effective shade for east and west windows. When possible, delay heat-generating activities such as dishwashing until evening on hot days.
2. Over most of the cooling season, keep the house closed tight during the day. Don’t let in unwanted heat and humidity. Ventilate at night either naturally or with fans.
3. You can help get rid of unwanted heat through ventilation if the temperature of the incoming air is 77 F or lower. (This strategy works most effectively at night and on cooler days.) Window fans for ventilation are a good option if used properly. They should be located on the downwind side of the house facing out. A window should be open in each room. Interior doors must remain open to allow air flow.
4. Use ceiling fans to increase comfort levels at higher thermostat settings. The standard human comfort range for light clothing in the summer is between 72 F and 78 F. To extend the comfort range to 82 F, you need a breeze of about 2.5 ft/sec or 1.7 mph. A sow-turning ceiling-mounted paddle fan can easily provide this air flow.
5. In hot climates, plant shade trees around the house. Don’t plant trees on the South if you want to benefit from passive solar heating in the winter.
6. If you have an older central air conditioner, consider replacing the outdoor compressor with a modern, high-efficiency unit. Make sure that it is properly matched to the indoor unit.
7. If buying a new air conditioner, be sure that it is properly sized. Get assistance from an energy auditor or air conditioning contractor.
8. Buy a high-efficiency air conditioner: for room air conditioners, the energy efficiency ratio (EER) rating should be above 10; for central air conditioners, look for a seasonal energy efficiency ratio (SEER) rating above 12.
9. In hot, humid climates, make sure that the air conditioner you buy will adequately get rid of high humidity. Models with variable or multi-speed blowers are generally best. Try to keep moisture sources out of the house.
10. Try not to use a dehumidifier at the same time your air conditioner is operating. The dehumidifier will increase the cooling load and force the air conditioner to work harder.
11. Seal all air conditioner ducts, and insulate ducts that run through unheated basements, crawl spaces, and attics.
12. Keep the thermostat set at 78 degrees F or higher if using ceiling fans. Don’t air-condition unused rooms.
13. Maintain your air conditioners properly to maximize efficiency.

Warm Weather Window Solutions
14. Install white window shades or mini-blinds. Mini-blinds can reduce solar heat gain by 40-50 percent.
15. Close south and west-facing curtains during the day for any window that gets direct sunlight. Keep these windows closed, too.
16. Install awnings on south-facing windows, where there’s insufficient roof overhang to provide shade.
17. Hang tightly woven screens or bamboo shades outside the window during the summer to stop 60 to 80 percent of the sun’s heat from getting to the windows.
18. Apply low-e films.
19. Consider exotic infills in your windows, a new technology that fills the space between panes with krypton or argon, gasses that have lower conductivity than air, and which boost R-values.
Tips for your A/C
19. Provide shade for your room A/C, or the outside half of your central A/C if at all possible. This will increase the unit’s efficiency by 5 percent to 10 percent.
20. Clean your A/C’s air filter every month during cooling season. Normal dust build-up can reduce air flow by 1 percent per week.
22. Turn off your A/C when you leave for more than an hour.
23. Several studies have found that most central air conditioning systems are oversized by 50 percent or more.
