Some HOT Weather Suggestions

Fans and Ceiling Fans

If you’re looking for ways to beat the heat, a ceiling fan can be a great investment for your home. This one appliance can make a room feel 6 or 7 degrees cooler, and even the most power-hungry fan costs less than $10 a month to use if you keep it on for 12 hours a day. Good fans make it possible for you to raise your thermostat setting and save on air-conditioning costs. Fans don’t use much energy, but when air is circulating, it feels much cooler. Ceiling fans are best, but a good portable fan can be very effective as well.

You should remember that even mild air movement of 1 mph can make you feel three or four degrees cooler. Also make sure your ceiling fan is turned for summer – you should feel the air blown downward.

Shades, drapes, or blinds

Install white window shades, drapes, or blinds to reflect heat away from the house. Close blinds, shades and draperies facing the sun (east-facing windows in the morning and west-facing windows in the afternoon) to keep the sun’s heat out and help fans or air conditioners cool more efficiently. Always remember that the best way to keep your home cool is to keep the heat out.

Internal Heat

The most common sources of internal heat gain are; appliances, electronic devices, and lighting. Be aware from where the heat is comming. Now if you have air conditioning, use it wisely. Don’t put lamps, televisions or other heat-generating appliances next to your air-conditioning thermostat, because the heat from these appliances will cause the air conditioner to run longer. The heat they produce will make it think your house is warmer than it really is, and your system will run harder than it needs to.

•Unless you absolutely need them, turn off incandescent lights and heat-generating appliances. Replace incandescent bulbs with compact fluorescents; they produce the same light but use a fifth the energy and heat.

•You should also try to avoid heat-generating activities, such as cooking, on hot days or during the hottest part of the day. If you are cooking, use your range fan to vent the hot air out of your house. By reducing the amount of heat in your home, you will have to use less energy to cool it.

Other things to remember

Humidity makes room air feel warmer, so reduce indoor humidity. Minimize mid-day washing and drying clothes, showering, and cooking. And when you must do these things, turn on ventilating fans to help extract warm, moist air.

Avoid landscaping with lots of unshaded rock, cement, or asphalt on the south or west sides because it increases the temperature around the house and radiates heat to the house after the sun has set.

If the attic isn’t already insulated or is under-insulated, insulate it NOW. Upgrading from 3 inches to 12 inches can cut cooling costs by 10 percent.

Some Summer Tips

Some "tips" to keep cool during these HOT Summer days.

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 dish washing 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.
