Do Smart Thermostats Really Save Money on Heating and Cooling?

December 07, 2020

Keeping your Rochester residence cozy can consume a big chunk of change. The usual family spends about $172 on monthly energy costs, according to ENERGY STAR®, or about $2,060 yearly. At least half of that is for heating and cooling.

Most residences use programmable thermostats, but many people don’t bother to set them. The process is bothersome, complicated and only provides you a few options for temperature settings. When your residence stays at an unchanging temperature throughout the day, it consumes utilities and adversely influences your monthly bill.

Smart thermostats learn from your day-to-day activities and adjust the settings to match it. But can using one really conserve money on heating and cooling? Yes, and here’s why.

Studies Show Smart Thermostats Save on Utility Expenses

Independent studies show these devices can lead to large savings.

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

With the typical smart thermostat running 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 installed, you’ll first set it just like your previous thermostat. You’ll turn it up and down, so the thermostat can figure out your needs. Then, it will get to work developing a program that helps you spend less money, whether you’re at home or out and about. Since it geofences with your smartphone, you won’t have to remember to adjust it when you go or return.

Pros and Cons of Using a Smart Thermostat


As we covered before, smart thermostats give many advantages to your home and utility expenses, such as:

  • No need to program—Your smart thermostat will pick up on your schedule, so you won’t be required to waste time adjusting programs or remember to change.
  • Knows when you come and take off—As many smart thermostats geofence with your phone, your residence will be put into an energy-efficient setting when you leave and be comfortable when you get back.
  • Remote temperature management—You’ll be able to watch your house’s temp from virtually any location, due to an app on your phone.
  • Watch heating and cooling use—Most smart thermostats provide in-depth data through their app, such as how long you used heating and cooling on a specific day.
  • Reminders—Some smart thermostats will let you know about important maintenance tasks, like when you need to replace your air filter.
  • Extra savings—Many local energy companies have rebates for smart thermostats, so call with yours for more info.


Having said that, there’s a few things you should consider when thinking about adding a smart thermostat in your home:

  • Compatibility—Subject to the type and age of your heating and cooling system, a smart thermostat might not be compatible. If you don’t know, it’s advisable to check with an HVAC pro like Brogan Heating & AC Inc. We also suggest having it professionally installed. This guarantees that you have the right number of wires and that it’s hooked up right. Some systems don’t have a common wire, which results in compatibility troubles with a smart thermostat. This wire powers your thermostat, so if your house doesn’t have a C-wire, we can install one.
  • Housing situation—If you own your home and plan to live there for years, it’s a wise investment to get a smart thermostat. If you’re planning to move in the next year or rent, we advise waiting unless you plan to take the thermostat with you. If you rent, you’ll often need to get your landlord’s permission first prior to putting in 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 often at the house? If that’s the case, you might not see as many savings, but you’ll have the perks of not being required to program or adjust a thermostat.
