Thermostats play an important role in our daily lives, cooling us down during the sweltering summer heat and keeping us warm and cozy during winter. While the average cost to install a thermostat is $175, pricing can vary.

Depending on the type of thermostat you get, these handy devices can even learn your habits and preferences to offer personalized comfort and monthly savings on your energy bills. Here, find out everything you need to know about how much it costs to install a thermostat based on factors like type, features, and installation method. 

How Much Does It Cost to Install a Thermostat?

It typically costs between $113 and $254 to install a thermostat, but the price varies by a few factors. For instance, there are several types of thermostats, including manual and smart thermostats. 

Each of these types features different price ranges, with manual thermostats ranging from $15 to $35 and smart thermostats costing around $200 to $300 or more. 

How Much Does It Cost to Install a Thermostat Yourself?

Since a thermostat connects to your home's electrical system, we recommend hiring a pro to install it to prevent potential electrical problems. This is especially true if you're installing a thermostat in a brand new area rather than simply replacing an old one because you'll need to know how to find and connect the proper wiring. 

Replacing a thermostat is often easier since the wires connecting the old thermostat are readily available and easy to identify. Still, unless you have electrical knowledge and skill, it's probably best to hire a local electrician to install or replace your thermostat.

Cost to Install it Yourself vs Hiring a Contractor

Electricians typically charge $65 to $100 per hour, and most electricians can install a thermostat in under two hours. 

However, some thermostats, like smart thermostats, need to communicate with other systems in your home, which may require additional wiring that takes longer to install and increases your labor costs by an hour or two.

There are several different types of thermostats. The type you buy significantly affects the overall cost to install it. 

Manual Thermostat Cost

Manual thermostats are generally the most budget-friendly thermostats, ranging from $15 to $35 per unit. As the name implies, manual thermostats are set manually by moving a small needle to your desired temperature. 

You also need to turn it on and off manually. These thermostats typically only have basic features, which is why they come at the lowest price point. It's worth noting that many manual thermostats are also being phased out because they contain mercury, which can be harmful to your health.

Non-Programmable Electronic Thermostat Cost

Non-programmable electronic thermostats are similar to manual thermostats except that they have a digital display that makes it easier to set specific temperatures. 

Like manual thermostats, these thermostats also usually only have very basic features, and they must be turned on and off manually, but they're quite affordable at around $20 to $50.

Electronic Programmable Thermostat Cost

Prior to the relatively recent invention of smart thermostats, electronic programmable thermostats were the most advanced thermostats on the market. They feature a digital face that makes it easy to set specific temperatures, and you can use them to program temperatures for various days and times. 

Since you can program them to automatically shut off or adjust the temperature at certain times, they can also help you save money on energy costs. These thermostats typically range from $20 to $150

Smart Thermostat Cost

Smart thermostats are the most expensive thermostats, costing about $130 to $300 or more, but they also have the most features. Not only can you program a smart thermostat, setting various temperatures for specific days and times, but you can do it right from your phone. 

Many smart thermostats can also "learn" your preferences, automatically setting to your desired temperature during a given time or day based on your habits. These added features can result in energy and money savings each month. 

What Factors Influence the Cost to Install a Thermostat?

From the type to the installation location, several factors affect the cost to install a thermostat. It's helpful to give each factor some thought so you can find the right thermostat for your household's needs. 

Thermostat Type

The biggest factor affecting thermostat installation costs is the type of thermostat you get. The most inexpensive options are manual thermostats, which only cost about $15 to $30, while smart thermostats are typically the most expensive, ranging from $130 to $300 or more.

DIY vs. Hire a Pro

Electricians charge about $65 to $100 per hour, and it usually takes them 1 to 2 hours to install a thermostat, so installing a thermostat yourself can save you money on labor costs.

However, because your thermostat is connected to your home's electrical system, we don't recommend taking on this project unless you have some background knowledge in electrical systems. Otherwise, you could run into some costly (and potentially dangerous) electrical problems.

Installing a Brand New Thermostat vs. Replacing a Thermostat

It often costs more to install a thermostat in a brand new location rather than replace an old one in an existing location. That's because your old thermostat is likely already connected to your home's electrical system, which means your electrician won't need to spend time finding and connecting new wires. 

FAQs About Thermostat Installation

Can my thermostat save me money on energy bills?

Depending on the type of thermostat you buy, it can definitely help you save money on your energy bills. Both smart and programmable thermostats make it easy to adjust your home's temperature so that you're not blasting the heat or air conditioning when you don't need it. 

While these thermostat types cost more upfront than manual and non-programmable thermostats, they can save you as much as $180 per year on your energy bills. 

Additionally, some states, like California and Florida, have pilot programs that allow smart thermostats to receive wireless signals from utility companies. These signals allow the thermostat to automatically adjust the temperature according to the price of electricity at various times per day, which can make the long-term savings of smart thermostats worth the initial cost.

How many thermostats do I need?

The number of thermostats you need depends on your home's size and HVAC systems. Very large homes or homes with multiple floors might have separate heating and cooling systems for different spaces or floors, often called "dual- or multi-zoned systems." These systems typically require you to have one thermostat for each zone.
