Do Smart Thermostats Really Save Money on Energy?

December 07, 2020

Keeping your Anchorage residence cozy can require a lot of money. A typical household spends about $172 on monthly heating and cooling expenses, according to ENERGY STAR®, or approximately $2,060 each year. At least half of that is consumed by heating and cooling.

Many residences use programmable thermostats, but most people don’t take the time to set them. The process is time-consuming, involved and only provides you limited options for desired temperatures. When your house remains at the same temperature throughout the day, it requires gas and electricity and adversely influences your monthly expenses.

Smart thermostats pick up on your routine and modify the temp to accompany it. But can getting one really help you spend less money on heating and cooling? Yes, and here’s why.

Studies Show Smart Thermostats Decrease on Utility Bills

Independent studies show these devices can result in major savings.

These studies included home heating and cooling costs in 41 states before and after putting in 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 each year.

With the average smart thermostat priced 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 first use it just like any other thermostat. You’ll switch it up and down, so the thermostat can learn about your needs. Then, it will start creating a program that helps you conserve more money, whether you’re at home or gone. As it geofences with your smartphone, you won’t have to think about adjusting it when you exit or return.

Pros and Cons of Having a Smart Thermostat


As we talked about prior, smart thermostats offer many perks to your residence and heating and cooling expenses, including:

  • No need to set—Your smart thermostat will learn your activities, so you won’t need to spend time adjusting programs or remember to change.
  • Knows when you come and go—Because lots of smart thermostats geofence with your phone, your home will be put into an energy-efficient setting when you leave and be comfy when you arrive.
  • Remote temperature supervision—You’ll be able to see your house’s temp from virtually any location, on account of an app on your phone.
  • Supervise heating and cooling use—Most smart thermostats offer detailed data through their app, including how long you required heating and cooling on a certain day.
  • Reminders—Certain smart thermostats will alert you to crucial maintenance tasks, like when you’re due to put in a new air filter.
  • Extra savings—The majority of local energy companies have rebates for smart thermostats, so call with yours for details.


However, there’s a couple of things you should consider regarding getting a smart thermostat in your house:

  • Compatibility—Subject to the type and age of your heating and cooling system, a smart thermostat might not be compatible. If you’re unsure, it’s advisable to check with an HVAC professional like Discount Mechanical Heating & Plumbing Services. We also recommend having it professionally installed. This confirms that you have the proper number of wires and that it’s hooked up correctly. Some systems don’t come with a common wire, which leads to compatibility troubles with a smart thermostat. This wire energizes your thermostat, so if your residence doesn’t have a C-wire, we can add one.
  • Housing situation—If you own your residence and are planning to be there for years, it’s a smart investment to install a smart thermostat. If you’re thinking about moving shortly or rent, we recommend waiting unless you want to take the thermostat with you. If you rent, you’ll typically need to get your landlord’s permission first prior to getting a new thermostat.
  • Cost—Smart thermostats are more expensive than programmable thermostats, and we suggest having yours professionally installed. However, the energy savings over time 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 large of savings, but you’ll enjoy the convenience of not being required to program or adjust a thermostat.
