Do Smart Thermostats Really Save Money on Energy?

December 07, 2020

Keeping your Plainfield house comfortable can eat up a good amount of money. A typical homeowner spends about $172 on monthly energy bills, according to ENERGY STAR®, or around $2,060 each year. At least half of that goes to heating and cooling.

The majority of houses use programmable thermostats, but many people don’t take the trouble to program them. The process is annoying, involved and only provides you a couple of options for desired temperatures. When your residence stays at the same temperature throughout the day, it wastes utilities and negatively impacts your monthly bill.

Smart thermostats pick up on your day-to-day activities and change the temperatures to match it. But can using one really conserve money on heating and cooling? Yes, and here’s why.

Studies Show Smart Thermostats Decrease on Heating and Cooling Costs

Independent studies have determined these devices can result in major savings.

These studies used home energy expenses in 41 states before and after adding a Nest smart thermostat. Nest said the study determined its thermostats can save up to 12% on heating and 15% on cooling, resulting in an average savings of $131 to $145 yearly.

With the average smart thermostat costing between $100–$250, those savings can help it pay for itself. And many local energy companies have rebates for smart thermostats as they’re ENERGY STAR® certified.

How Does a Smart Thermostat Work?

After your smart thermostat is installed, you’ll at first program it just like any other thermostat. You’ll set it up and down, so the thermostat can determine your wants. Then, it will get to work developing a program that helps you save money, whether you’re at your house or away. Since it geofences with your smartphone, you won’t have to think about adjusting it when you exit or get back.

Pros and Cons of Using a Smart Thermostat


As we talked about prior, smart thermostats offer lots of advantages to your house and utility costs, such as:

  • No need to set—Your smart thermostat will learn your activities, so you won’t be required to use up time using programs or remember to change.
  • Knows when you arrive and leave—Because a lot of smart thermostats geofence with your phone, your house will move into an energy-efficient setting when you take off and be comfy when you arrive.
  • Remote temperature management—You’ll be able to watch your house’s temp from virtually any location, because of an app on your phone.
  • Monitor heating and cooling use—The majority of smart thermostats offer detailed data through their app, like how long you used heating and cooling on a certain day.
  • Reminders—Select smart thermostats will let you know about essential maintenance tasks, including when you need to replace your air filter.
  • Additional savings—Most local energy companies offer rebates for smart thermostats, so call with yours for more information.


However, there’s several areas you should contemplate regarding adding a smart thermostat in your home:

  • Compatibility—Based on the type and age of your heating and cooling system, a smart thermostat might not be compatible. If you’re unsure, it’s best to contact an HVAC specialist like PWA Heating & Cooling Inc. We also suggest having it professionally installed. This confirms that you have the correct number of wires and that it’s connected right. Some systems don’t come with a common wire, which leads to compatibility issues with a smart thermostat. This wire runs your thermostat, so if your residence doesn’t have a C-wire, we can add one.
  • Housing situation—If you own your home and are planning to live there for many years, it’s a good investment to get a smart thermostat. If you plan to move soon or rent, we recommend delaying unless you plan to take the thermostat with you. If you rent, you’ll often need to get your landlord’s permission first ahead of putting in a new thermostat.
  • Cost—Smart thermostats are pricier than programmable thermostats, and we suggest having yours professionally installed. However, the energy savings over its lifetime can help pay for itself.
  • Lifestyle—Does a family member work from home, or is someone frequently at the house? If that’s the case, you might not see as large of savings, but you’ll get the convenience of not being required to program or adjust a thermostat.
