For a standard, 2,000-square-foot home, the cost of installing or replacing a thermostat averages between $107 and $248, including the price of the unit and professional installation. The national average cost is $163. The thermostat will run between $15 and $300, depending on the type and its features. A licensed electrician can typically set one up in fewer than two hours at a rate of $65 - $85 per hour.
It is possible to save some money by installing or replacing your home, apartment, or business thermostat yourself, but you will need basic electrical knowledge. Potential consequences of improper installation include electric shock, blowing a circuit breaker, damaging the thermostat unit, or even the AC/furnace unit itself.

Prices per Thermostat Unit Type ($15 - $300+)

Gone are the days when your only choice for a new thermostat was a metal box with a little wheel you turned manually to change the temperature. Today we have many more choices with many more features. But with extra features come extra costs. Here are a few factors that will affect the cost of installing a new thermostat.
Thermostats - Prices, Pros & Cons
TypeCostProsCons
Mechanical/ Manual$15-$35 Lowest costNon-programmable, contain mercury
Non-Programmable Electronic$20-$50Relatively low cost, digital readoutManually controlled
Programmable Electronic$100-$150Easy-to-read display, auto-adjustsMore expensive, limited preset programs
Smart$200-$300+Remote management, automatic programs, long-term savingsMost expensive, more difficult to install, requires Wi-Fi

Mechanical/Manual/Non-Programmable ($15 - $35)

For the lowest price, you can still get the old-fashioned, manual style of residential or commercial thermostat that functions entirely by moving a small needle left and right to select the temperature. While these are common, they are being phased out of use because they contain mercury.
This will be your least expensive option, but it will also come with the fewest features. Like a light switch, this must be turned on and off manually. You must also switch it from heating to cooling and vice versa.

Non-Programmable Electronic ($20-$50)

For a slightly higher cost, you can purchase an electronic and programmable thermostat that allows you to set heating and cooling options, but has very few other features. While it must still be turned on and off and switched manually, the digital display can make it easier to select a specific temperature.

Electronic Programmable ($20 - $150)

Until recently, these were the most advanced and expensive option available at a cost of $20 - $150. Features include the ability to set heating and cooling options, and program temperatures according to preset weekday, weekend, and week-long programs. Many of these models can have numerous programs set for days at a time. These components help control homeowners’ HVAC costs.They may illuminate for easy access in the dark. And many of the newest models have touch screens.

Smart/Learning/Communicating ($200 - $300+)

Now that nearly everyone has a smartphone, home and business thermostat technology has been updated to include models that can be operated remotely. These “smart” thermostats are significantly more expensive than other options, costing $200 - $300 or more. New units with additional features are hitting the market regularly and may come with an even higher price tag.
In addition to being smart, some high-end devices can “learn” your preferences. This provides the benefits of a programmable unit without the user having to set it. Functional options are endless and are set up automatically based on how you use it. However, these devices are best suited for homeowners with a consistent schedule, because consistency will ensure programmed temperatures accurately reflect the homeowner’s preferences. Selecting the right smart thermostat for your home will depend on your preferences.
These can also be connected to Wi-Fi to be monitored, set, and/or managed remotely from any internet-enabled device. Most high-end equipment also “communicates” with the heating and cooling systems they are controlling. Wiring for these systems is more advanced, but the added work comes with added benefits like troubleshooting assistance and maintenance warnings.
Because of these features, a smart thermometer can save both energy and money. According to a study by one manufacturer, homeowners can save 10% - 15% ($131 - $145) per year on their heating and cooling costs with a smart unit.

Thermostat Installation or Replacement Costs

Most electricians can install or replace a home, apartment, or business thermostat in two hours or less at a rate of $65 - $85 per hour for a total labor cost of less than $170. Whether you opt for a modern, digital model or a simple, manual one, the installation costs will not differ by be significantly difference. It is still an electrical job no matter which type you choose.
If you need multiple units installed in your home, ask your pro what the price would be to put them in all at once. Although the overall charge may be higher, the per unit rate will almost always be considerably lower if a pro only needs to make one trip to your home.
Because it does involve electricity, this is a job best left to a professional, but it is a moderately simple electrical procedure and should not be very expensive. Homeowners with basic electrical knowledge or experience may choose to install or replace a thermostat themselves. Replacement will be easier than wiring a new one, because the existing wires are already in position and accessible. You should always follow manufacturer’s instructions. Stop work and contact a professional immediately if you do not feel confident in your abilities. Errors could lead to injury, damage, and effects on your home’s resale value.

Replacing

The amount of time this job takes will be the biggest cost factor in replacing a unit. It commonly requires repair or replacement of faulty wiring, cutting into walls, repairing a circuit, or changing the location of the unit. Labor rates will depend on how complex the process ends up being.
The type of model you select could also impact your labor costs. Smart thermostats that communicate with HVAC units sometimes require additional wiring to connect the two, which may take more time and increase labor charges.
New construction installation costs may be less if they are factored into the contract with the rest of the property’s electrical work. You may also see savings if your property is part of a new development where the contractor has more than one job to complete.

Number to be Installed or Replaced

Additional thermostats mean added costs for the units and the installation. Extra units will allow you to control the temperature from multiple locations within your home, apartment, or business, like upstairs and downstairs floors. While convenient, this practice is not recommended, because it can lead to improper heating and cooling.
To set different temperatures for different areas of the home using one HVAC unit, you’ll need a “multi-zoned” system with electronic baffles. On top of the price of the unit(s), you’ll need to factor in material and labor costs. Baffle charges will vary based on your home’s duct sizes. You should also factor in labor for both a licensed HVAC professional and electrical contractor, because this job is too complicated to do yourself.

Energy Cost Savings

Although both digital/programmable and smart models cost more upfront than a manual one, the more expensive version could save a homeowner as much as $180 per year on energy bills. Overall, you will be more comfortable and spend less time adjusting your home or apartment thermostat with a digital model. Program it for your comfort and schedule.
In some areas of the country, like Florida and California, pilot programs exist in which smart models receive wireless signals from the utility company. These units then adjust the temperature according to the price of electricity at different times of the day. At a rate of about 70 cents an hour, reducing air conditioning usage for just an hour per day would save the average homeowner $65 - $110 in just one summer.

Oven, Dryer, & Water Heater Thermostats

Appliances also include thermostats. While these internal units are relatively inexpensive, they can be difficult to install. For example, replacing a thermostat on a water heater costs between $100-$300. Therefore, you should consult a professional for appliance service and installation costs.

DIY or Hire a Pro

Electrical work should be left to a professional to prevent injury or damage. However, those who are mechanically inclined can often install a standard manual or electronic thermostat by simply following the instructions that come with the device.
If you have no skill or experience with electrical tasks, if you are adding a smart thermostat, or if you are dealing with atypical circumstances (multi-zone baffles, whole-home humidifiers, or dual-fuel systems), you should consult a licensed thermostat installation company and/or HVAC professional. While it may cost more upfront, ensuring the job is done right can save you time and money on repairs and damages in the long run.
