In one of my earlier posts, I mentioned adjusting your thermostat in your home. My husband and I set our A/C at a higher temperature in the summer when we are not home. In the winter, we set the heater at a lower temperature while we are away. Now, wouldn't it be easier if you had a programmable thermostat that did all the remembering for you?
You can buy a programmable thermostat at most any home improvement store. They vary in price, but I have found some as little as $40. Plus, you could get it much cheaper on ebay or Amazon.com.
You don't even need a handyman to install it. Read the instructions and use videos on youtube.om for guidance.
