Before you purchase a new smart thermostat, there are a few things you'll want to consider. First, look to make sure it is compatible with your heating or cooling units. Determine whether you'll need to purchase a c-wire or other equipment in order to get it connected and up and running.

Frequently Asked Questions

What Should You Set Your Thermostat to in the Winter?

This will depend on your personal preferences. The lower you can set it your thermostat to, the more you will be able to save. Generally, a temperature around 70 degrees, or even a touch lower is recommended. If you have a smart thermostat, you could set it to be even a little colder during the parts of the day that no one will be home in your house.

What Should You Set Your Thermostat to in the Summer?

To help you save money while still staying cool, the United States Department of Energy recommends that you set your thermostat to 78 degrees. If this is too warm for you, you could program your smart thermostat to increase the temperature to 78 degrees when you are away and return it to a lower temperature that is more comfortable when you are home.

Does a Smart Thermostat Really Save You Money?

Simply purchase a smart thermostat won't save you money. What can save you money is programming the thermostat to keep your home at more energy-efficient temperatures during the times you are not home.

For example, if you normally cool your home to 702degrees in the summer, you can use your thermostat to bump the temperature up to 78 during the times you will be gone, and then have it cool it back down before you will return. This can help you use less energy and save some money each month.
