Remember that extreme temperatures can build in an attic without proper ventilation, especially with a dark colored roof.
Set your thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
Install tight-fitting, insulating window shades on windows that feel drafty after weatherizing.
Energy Star labeled ceiling fans with lighting attached use 40% less energy than conventional models, keeping you cool for less.
Trees that lose their leaves in the fall (i.e., deciduous) are the most effective at reducing heating and cooling energy costs. When selectively placed around a house, they provide excellent protection from the summer sun but permit winter sunlight to reach and warm your house. The height, growth rate, branch spread, and shape are all factors to consider in choosing a tree.
Programmable thermostats are simple, inexpensive devices that provide better savings than any other energy efficiency measure. Available in several shapes and sizes, they can be added to most modern hvac systems and can pay for themselves in as little as a month.
Back to school time means the home heating season is beginning to kick in. Have your chimneys and vents checked before you fire up the furnace or fireplace to make the most of those cool fall evenings.
The National Fire Protection Association (in NFPA 211) recommends you have your chimney checked at least once a year, and cleaned if needed. Heavy users need more frequent check-ups.
Attic work is hot and tiring. Work in the morning before it gets hot and keep lots of cool liquids handy to avoid over heating.
Set the fan on your central air conditioner to "on" rather than "auto." This will circulate air continuously, keeping the temperature more even throughout the house and aiding in dehumidification.
