At Elmer’s One Hour Heating and Air Conditioning, every new AC system we install also comes with a programmable thermostat. This helps you save energy and money on your electric bill, as well. When properly programmed, a programmable thermostat allows you to predetermine what temperature you want your home at certain times of the day. If your family is out of the house by 8:30am, you can set the thermostat to 82 at 8:30am Monday – Friday, for example. Likewise, you can set the thermostat to cool down the house about 15-20 minutes before everyone arrives home. Less demand on your AC during the summer and heating during the winter means less demand on your bank account when the monthly energy bill arrives.
