How Does a Smart Thermostat Save Money on Energy Bills?

December 07, 2020

Keeping your McMurray residence comfortable can eat up a big chunk of change. The usual family spends about $172 on monthly heating and cooling bills, according to ENERGY STAR®, or approximately $2,060 annually. At least half of that is for heating and cooling.

The majority of houses use programmable thermostats, but the majority of people don’t take the trouble to set them. The process is bothersome, complicated and only offers you a couple of options for temperature changes. When your residence stays at an unchanging temp throughout the day, it wastes gas and electricity and adversely affects your monthly expenses.

Smart thermostats pick up on your schedule and change the settings to coordinate it. But can installing one really save you money on heating and cooling? Yes, and here’s why.

Studies Show Smart Thermostats Save on Utility Expenses

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

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

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

How Does a Smart Thermostat Work?

After your smart thermostat is ready to go, you’ll at first set it just like any other thermostat. You’ll set it up and down, so the thermostat can figure out your needs. Then, it will start creating a program that helps you spend less money, whether you’re at your house or gone. As it geofences with your smartphone, you won’t have to remember to adjust it when you go or get back.

Pros and Cons of Having a Smart Thermostat


As we mentioned before, smart thermostats provide lots of perks to your house and heating and cooling expenses, including:

  • No need to adjust—Your smart thermostat will adjust to your routine, so you won’t be required to spend time setting programs or remember to adjust it.
  • Knows when you get home and take off—Since lots of smart thermostats geofence with your phone, your house will move into an energy-efficient setting when you go and be cozy when you get back.
  • Remote temperature management—You’ll be able to watch your home’s temp from just about any location, thanks to an app on your phone.
  • Supervise heating and cooling use—The majority of smart thermostats provide great data through their app, such as how long you needed heating and cooling on a particular day.
  • Reminders—Certain smart thermostats will alert you to critical maintenance tasks, such as when you’re due to put in a new air filter.
  • Added savings—The majority of local energy companies provide rebates for smart thermostats, so contact with yours for more information.


Having said that, there’s several areas you should consider when thinking about adding a smart thermostat in your residence:

  • Compatibility—Depending on the type and age of your heating and cooling system, a smart thermostat might not work. If you’re not sure, it’s recommended to check with an HVAC professional like Kowalski Heating, Cooling & Plumbing. We also advise having it professionally installed. This ensures that you have the proper number of wires and that it’s connected accurately. Some systems don’t have a common wire, which leads to compatibility problems with a smart thermostat. This wire runs your thermostat, so if your residence doesn’t have a C-wire, we can install one.
  • Housing situation—If you own your home and are planning to reside there for years, it’s a good investment to get a smart thermostat. If you plan to move shortly or rent, we advise holding back unless you will take the thermostat with you. If you rent, you’ll usually need to secure your landlord’s permission first prior to installing a new thermostat.
  • Cost—Smart thermostats cost more than programmable thermostats, and we advise having yours professionally installed. However, the energy savings over the years can help pay for itself.
  • Lifestyle—Does a family member work from home, or is someone frequently at the house? If so, you might not see as big of savings, but you’ll enjoy the perks of not needing to program or adjust a thermostat.
