Cost Estimator by Thermostat Type

The cost of replacing your thermostat will depend on the type you choose. From basic models to more advanced smart thermostats, here’s a general cost breakdown according to each type:

Thermostat TypeAverage Cost (Thermostat Only)Average Cost (Including Professional Installation)
Manual Thermostat$20 – $40$40 – $150
Digital Thermostat$40 – $150$60 – $350
Wi-Fi Thermostat$60 – $230$120 – $400
Smart Thermostat$140 – $310$150 – $500

Manual Thermostat

A manual thermostat, also known as an analog or non-programmable thermostat, is an affordable option, costing from $40 to $150, including installation. These thermostats are pretty straightforward to install but aren’t too accurate or efficient, so they’re particularly suited for areas that don’t need precise temperature control.

With a manual thermostat, all you need to do is set your desired temperature with the simple twist of a dial or knob, and your HVAC system will do its job. But beware, if you don’t monitor the thermostat, you could end up spending more money than necessary on energy bills.

Digital Thermostat

If you’re looking to save money on your energy bills, upgrading to a digital thermostat is an easy way to do it. Programmable models let you set temperatures without having to adjust things manually every time. According to, a programmable unit can help you save up to 10% on your energy costs, so it’s well worth the investment.

There are two types of digital thermostats, programmable and non-programmable, with the programmable ones being more expensive. On average, the cost of a digital thermostat ranges from $60 to $350 installed, depending on the thermostat features.

If you’re looking for a simpler model, non-programmable digital thermostats are cheaper and come with basic features like temperature control and a digital display. Non-programmable digial thermostats don’t offer many extra features, though, so you may want to think twice before investing in one.

Before installing a digital thermostat, make sure it’s compatible with your system. Consult your HVAC technician for more information.

Smart Thermostats

A smart thermostat is a pricier option for heating and cooling your home, but it comes with loads of unique features so you can keep your house comfortable all the time. From voice control to energy-saving modes, you’ll be able to keep a close eye on your HVAC system even when you’re not around.

Plus, with Wi-Fi capabilities, you’ll be able to monitor your HVAC system no matter how far away you are. The cost of smart thermostat units can range from $150 to $500 in total, depending on the features and brand.

Wi-Fi Thermostats

A Wi-Fi thermostat might be the way to go for those looking for something in between smart thermostats and more basic models. The Wi-Fi thermostat installation cost averages around $120 to $400 in total, though some of the pricier models offer extra features that can be worth the investment.

With a Wi-Fi thermostat, you’ll still get to control your HVAC system from anywhere, track your energy usage, and more. However, a few features, like voice control, are not available with basic Wi-Fi models, so make sure you know what features you’re getting for the price.

Other Factors That Affect Cost

If you’re budgeting for a new thermostat, there are a few things to consider that might change the price tag. From the type of your HVAC system to the labor costs associated with the installation, here’s a breakdown of some common cost factors:

Thermostat Cost by Home Device Type

When it comes to thermostats, complex HVAC units such as boilers and water heaters may require a more costly model that is able to regulate the boiling water accurately. On the other hand, an AC unit thermostat may be more basic and, therefore, less expensive in comparison.

Generally, a boiler thermostat can cost from $200 to $500 in total, while an air conditioning thermostat might only cost from $110 to $450 installed. Here’s a breakdown of thermostat costs for common home devices that require one: 

Device TypeThermostat Average Cost (Thermostat Only)Thermostat Average Cost (Installed)
Air Conditioner$35 – $150$110 – $450
Furnace$45 – $250$150 – $500
Boiler$150 – $250$200 – $500
Dryer$15 – $40$150 – $350
Refrigerator$15 – $45$150 – $400

Thermostat Cost By Brand

The brand of your home thermostat can have a significant impact on the final price. Although the installation fee may not vary much between different models, some brands are pricier because of their extra features. Popular thermostats like Nest, Ecobee, and Honeywell typically come with a heftier price tag, costing up to $500, including installation.

BrandAverage Cost (Installed)
Ecobee$250 – $420
Hive$200 – $400
Honeywell$120 – $420
Lux / Kono$170 – $300
Google Nest$220 – $500
Emerson Sensi$180 – $350

Many of the higher-end brands offer bonus features that make their thermostats well worth the money, such as:

  • Motion sensors to save energy when no one is in the room
  • Geofencing to turn on and off the thermostat based on where you are
  • Advanced air filter monitoring that can alert you when it needs to be replaced

Plus, many of these thermostats will pay for themselves over time due to their energy efficiency.

However, if you’re looking for a budget-friendly option, there are still some great options. Basic models from brands like Sensi can be found for under $180, including installation. While most entry-level thermostats don’t offer the fancy features of the pricier models, you can still control and monitor your temperature and efficiency levels. Additionally, many of these brands also offer Wi-Fi-compatible models that you connect to an app on your phone or device.

Labor Costs

When it comes to labor costs, the installation of a new thermostat usually ranges from $100 to $250. However, this price can be higher depending on the job’s complexity. If you have an existing thermostat, the installation should go quickly and smoothly, but if your home has old wiring or no wiring at all, the cost may be higher. It can take up to three hours for a technician to install the thermostat, and you may need to pay extra for their labor.

HVAC professionals typically charge between $70 and $150 per hour, but an electrician can be a more budget-friendly option. Electricians usually charge around $50 to $110 per hour, though you should make sure they have the knowledge to install your particular thermostat.

Thermostat Wire Installation Cost

If you don’t already have wiring or need to upgrade your wiring, that can add an extra $100 to $150 on top of the thermostat installation fee. Some types of thermostats require a dedicated “C-wire” to work properly. These wires usually need to be run through the walls and connected directly to the breaker box. This process can take up to an extra hour, so factor this into the installation cost.

Number of Thermostat Units

The number of thermostat units you need to be installed can also affect the total cost. If your home has multiple zones or requires more than one thermostat, you may need to pay for additional units. Depending on the specific unit and brand, each thermostat can cost from $65 to $180 without installation.

If you decide to purchase multiple units, you may be able to get a discount from the manufacturer or installer.

Thermostat Accessories Cost

In addition to the basic thermostat, you may need to purchase extra accessories depending on your setup. For example, a thermostat cover or wall mounting plate can cost up to $45. Other accessories, like sensors, can range from $30 to $150, depending on the type.

ProductAverage Cost
Wall Plate$6 – $25
Thermostat Cover$15 – $45
Temperature Sensors$30 – $150

In addition to the thermostat, you may need additional HVAC services, such as duct cleaning or repair, system maintenance, or even energy efficiency testing. These services can add an extra cost to your overall installation fee.

Thermostat Repair Cost

If you already have a thermostat but it’s not functioning properly, a technician may be able to repair it for around $100 to $330. Depending on the complexity of the repair, it could be more or less expensive. In most cases, a repair job can be completed in about an hour or two.

If the room temperature is constantly fluctuating, it could be a problem with your HVAC system. In this instance, you will likely need to bring in a professional HVAC technician to assess the situation. Basic HVAC repairs costs range from $180 to $580.

HVAC Maintenance

The HVAC maintenance process will involve a technician inspecting the system for any potential issues, as well as checking the accuracy of your thermostat. Generally, the thermostat service fee is included in the HVAC maintenance cost. On average, HVAC maintenance ranges from $85 to $170 per visit.

Drywall Repair

If replacing the thermostat requires cutting into walls, you may need to hire a professional drywaller to patch up any holes. The drywall repair cost will depend on the size of the damage, but an expert usually charges between $70 and $120 per hour. The average patch job takes about an hour to complete.

Thermostat Replacement Cost by Location

The price tag for replacing a thermostat can be heavily influenced by location. In crowded cities and big metropolitan areas, the labor cost for installation is usually more expensive than in smaller towns due to overall higher living costs. Additionally, some locations can have increased labor charges due to high demand.

To find out typical thermostat replacement costs in your area, reach out to a local HVAC technician.  

FAQ About Thermostat Installation

Can I install a thermostat myself?

The installation of a thermostat can involve wiring and electrical work, so it’s typically best to leave it to a professional. Additionally, DIY attempts at a thermostat installation without proper experience and training could damage the thermostat and may void its warranty.

When should I replace my thermostat?

It could be time to upgrade if you have an outdated thermostat model. The new models are more energy-efficient and can help you save on utility bills. Similarly, if you have a faulty thermostat that’s not functioning right, it usually makes more sense financially to purchase a new one than attempt to repair it.

What is the ideal temperature setting for my thermostat?

The best setting for your thermostat depends on several factors, such as the time of year. Generally speaking, it’s recommended to set the temperature between 68 degrees and 78 degrees Fahrenheit. This should provide an energy-efficient balance between comfort and cost.

Where is the best place to put a thermostat in the house?

The ideal location of the thermostat depends on the size and layout of your home. Usually, it’s best to place the thermostat in an area that is away from direct sunlight, drafts, and electronics. The thermostat should also be at a central location in the home to provide an accurate temperature reading.
