    According to ENERGY STAR®, which is a joint program of the Department of Energy and the Environmental Protection Agency, the average household spends more than $2,200 a year on energy bills - nearly half of which goes to heating and cooling. They suggest that homeowners could save about $180 a year by properly setting their programmable thermostats and maintaining those settings.

    Of course, the most common thermostats regulate your heating, ventilating, and air conditioning systems. But there are also plug-in thermostats for your portable heater and air conditioner, as well as some models that you can control by phone. In fact, there's a programmable thermostat for almost every lifestyle. See which one is right for you.

Install a Heating and AC Thermostat

If your home has an air conditioner and either a furnace, boiler, or heat pump, you'll want to install a heating and AC thermostat. There's a wide range of choices, and each one is specifically designed for this kind of heating and cooling combination. Whichever one you choose, we recommend that you have it installed by a professional because of the potential dangers of electrical shock.

Install a Heating Thermostat

If your home doesn't have an air conditioner, but does have a furnace, boiler, or electrical heat, you'll want to install a heating thermostat. These models have the same stylish look and digital display as the heating and AC thermostats, but the mechanism is focused on heating only. Whichever one you choose, we recommend that you have it installed by a professional because of the potential dangers of electrical shock.

Install a Telephone Controlled Thermostat

If you have a vacation home or an unpredictable schedule, you might consider a programmable thermostat that works with a telephone controller. This device allows you to adjust your heating and cooling systems by using a touch tone phone. But be sure that your thermostat is equipped to accept a phone connection. The list below shows you your options. As always, whichever one you choose, we recommend that you have it installed by a professional because of the potential dangers of electrical shock.

Install a Plug-In Thermostat

The plug-in thermostat operates the same way as the other programmable thermostats, except that it's specifically designed for window air conditioners and portable space heaters. It comes with two separate programs, so you can control both your heating and cooling. As with all programmable thermostats, we recommend that you have it installed by a professional because of the potential dangers of electrical shock.
