Why Your Electric Bill Might Be Too High
Do you feel like your electric bill is too high every month? You’re not alone. Many people don’t know that an old thermostat can waste a lot of money.
A thermostat is the small box on your wall that controls how hot or cold your home gets. If yours is old, it might be wasting energy and costing you extra money.
So, can a new thermostat save money? Yes! In this guide, you’ll learn exactly how much money you can save and how it works.
How Does a Thermostat Save Money?
Let’s look at the smart ways a new thermostat helps you save.

It Keeps the Perfect Temperature
Old thermostats are not very smart. When you turn them up, they make your home too hot. When you turn them down, it gets too cold. This wastes energy.
New smart thermostats are different. They learn what temperature you like. They keep your home at just the right temperature. No more wasting energy by making it too hot or too cold.
It Changes Temperature When You’re Away
Think about this: Why heat or cool your home when nobody is there?
Smart thermostats learn your daily routine. They know when you leave for work or school. They know when you go to bed. They automatically turn the heat or AC down when you’re not home. This saves a lot of money.
You don’t have to remember to change anything. The thermostat does it all by itself.
It Knows When You Leave Home
This feature is really cool. A new thermostat can connect to your phone. It uses your phone’s GPS to know where you are.
When you leave home, it automatically switches to energy-saving mode. When you’re coming back, it starts warming or cooling your home again. Your house feels comfortable when you walk in, but you didn’t waste energy while you were gone.
You Can Control It From Anywhere
Did you ever forget to turn down the heat before leaving for a trip? With a smart thermostat, no problem!
You can use an app on your phone to change the temperature from anywhere. At work, on vacation, or at a friend’s house – you can always control your home’s temperature. This stops you from wasting money when you forget.
It Reminds You to Do Important Things
Smart thermostats help you take care of your heating and cooling system. They remind you when to change the air filter.
Why does this matter? When air filters get dirty and clogged, your system has to work harder. That uses more energy and costs more money.
Some fancy thermostats can even find small problems before they become big, expensive problems. This can save you hundreds of dollars in repair costs.
How Much Money Can You Actually Save?
Let’s talk about real numbers. Can a new thermostat save money? Here’s what you can expect.
Average Savings
Most people save between 8% and 20% on their heating and cooling bills.
Let’s say your electric bill is $150 every month. If you save 15%, that’s $22.50 each month. Over a whole year, that’s $270 in savings!
The Simple Trick That Saves 10%
Here’s an easy tip: Turn your thermostat down 7 to 10 degrees for 8 hours each day. This could save you 10% every year.
A smart thermostat does this for you automatically. It turns down the temperature when you sleep or when you’re at work. You save money without thinking about it.
Will It Pay for Itself?
Smart thermostats usually cost between $100 and $250. But remember, you’re saving money every single month.
If you save $20 per month, your thermostat will pay for itself in about 5 to 12 months. After that, it’s pure savings in your pocket. Year after year, you keep saving money.
Who Saves the Most Money?
Some people save even more money with a smart thermostat. Let’s see who benefits the most.

People in Very Hot or Very Cold Places
Do you live somewhere that gets really hot in summer? Or really cold in winter? Then you’re in luck!
Places like Lafayette see very hot summers and need lots of AC. In these areas, your heating and cooling system runs a lot. That means a smart thermostat can save you even more money. You might save 15% to 20% instead of just 8%.
Vacation Homes
Do you have a vacation home or cabin? A smart thermostat is perfect for you.
You can keep the heat or AC on a low setting when nobody is there. Then, before you arrive, you can turn it up from your phone. This saves tons of money because you’re not heating or cooling an empty house all the time.
Homes with Zone Control
Some homes can control the temperature in different rooms separately. This is called a zone system.
If you have this, a smart thermostat gives you even more control. You can keep bedrooms cool at night but save energy in the living room. This means you only heat or cool the rooms you’re actually using.
Important Things You Should Know
Before you buy a new thermostat, here are some helpful tips.
Old Thermostats Don’t Work Well
Some people have old programmable thermostats. These can save money, but there’s a problem.
Studies show that almost 50% of people don’t set them up right. Or they forget to adjust them when seasons change. If you don’t use it correctly, you won’t save money.
Smart thermostats fix this problem. They do everything automatically. You don’t have to remember anything. That’s why they work so much better.
Special Note for Heat Pumps
Do you have a heat pump instead of a regular heater? Pay attention to this part.
If you turn down a heat pump manually in winter, it can actually waste money instead of saving it. That’s because it turns on backup electric heat, which costs more.
But don’t worry! Newer smart thermostats are made to work with heat pumps. They have special settings that save you money the right way.
Put It in the Right Spot
Where you put your thermostat matters a lot.
It should go on an inside wall, away from windows. Don’t put it near doors where cold air comes in. Keep it away from sunny spots.
If your current thermostat is in a bad spot, replacing it and moving it to a better location will help it work much better. This means more savings for you.
Replace Old Thermostats
Is your thermostat 10 years old or older? It’s time for a new one.
Technology has improved so much in the last 10 years. A new thermostat will save you way more money than that old one ever could.
How to Pick the Right Thermostat
Not all thermostats are the same. Here’s how to choose a good one.
Think About Your Budget
Smart thermostats come in different price ranges:
- Basic models cost around $100 to $150
- Mid-range models cost $150 to $200
- Premium models cost $200 to $250 or more
Even the basic models will save you money. You don’t need the most expensive one to see savings.
