Smart thermostats allow you to control your home climate from your phone and set schedules according to your daily routine. Certain models can even learn your temperature preferences and adjust accordingly based on your preferences, resulting in effortless temperature control.

Smart thermostats range anywhere from $130 to $300 or more; the long-term benefits in terms of energy efficiency and convenience can make smart thermostats a worthwhile investment for many homeowners.

Labor Costs

HVAC technicians charge an average of $25 per hour, and the total labor cost to install the thermostat can be anywhere from $50 to $100.

However, installing your own thermostat can help you save on installation costs, and you will just have to pay for the thermostat device. In case you decide to opt for professional thermostat installation services, you will incur labor costs. These prices are based on the time these specialists invest and the extent of the installation’s complexity.

Type of HVAC System

Installing a thermostat for heat-only or furnace systems generally incurs lower costs compared to thermostats designed for both heating and cooling systems. This is because the latter demands additional wiring and setup for comprehensive functionality, consequently elevating the overall installation cost.

If you have electric heating systems like baseboard heaters, they use high-voltage thermostats, which electricians install. They often charge a high hourly rate, between $65- $100

Number of Thermostats

The cost of thermostat installation shifts significantly based on the number of units required. In the case of manual and programmable thermostats, multiple units are required for HVAC zoning. This results in higher overall installation expenses, as each thermostat requires dedicated wiring and setup.

In contrast, smart thermostats offer the capability to control temperature variations in different zones using a single thermostat combined with various sensors. This eliminates the need for separate thermostats in each zone, streamlining the installation process and reducing associated costs.

New Wiring

If your existing wiring is compatible with the new thermostat, the installation process will be hassle-free, and you will also save on installation costs. However, if you are installing a thermostat in a newly built house, additional wires are required. Specifically, smart thermostats require a C-wire, and hiring a professional to run a new one can cost between $90 and $135.

Tip: You can opt for a C-wire adapter if installing a C-wire isn’t feasible in your home.

Add-Ons

When installing a thermostat, several additional expenses may arise beyond the basic unit cost.

• Some smart thermostat installations may necessitate a C-wire adapter. This adapter ensures a stable power supply for smart thermostats that rely on continuous power to function optimally. Some companies provide it in the box along with the smart thermostat without any additional costs. In case it doesn’t come with the box, adapters are priced around $20 to $40 each.
• Expenses can also be related to additional enhancements for thermostats, including thermostat lockboxes, ranging from $15 to $30 each.
• Sensors are installed with smart thermostats at various locations around your house for a balanced temperature. They can range from $30 to $40.

Installing a New Thermostat vs. Replacing a Thermostat

The replacement process involves upgrading an existing thermostat, while installation entails setting up a new system from scratch. Wiring is a major factor when it comes to installing a new thermostat or replacing an old one.

Home thermostat replacement is a relatively simple task, especially if you are adding a similar model in an area with the appropriate wiring already in place. It means that you won’t have to cut holes in the wall or deal with any troublesome wiring. This way you can save on labor costs. Even if you decide to hire a technician for home thermostat replacement, it would still cost less than installing a new thermostat.

According to Josh Mitchell, HVAC technician and owner of Air Conditioner Lab, “For a straightforward replacement where the new thermostat is similar to the old, thermostat replacement costs around $50 to $100. However, this can vary based on regional labor rates and the specific technician you hire.”

However, in some cases, you may have to run additional wires. Most older homes lack a C-wire, which is necessary in the case of smart thermostats. “If the new thermostat requires additional wiring or if there are compatibility issues with your existing HVAC system, installation costs can increase significantly. This might require extra labor and materials, potentially bringing the cost to anywhere between $150 and $250,” Mitchell adds.

Relocating a Thermostat

The cost of moving a thermostat varies based on factors such as the type of thermostat, existing location, relocation placement, and type of HVAC unit. It can range from $100 to $500.

Suppose wiring already exists in the new location. In that case, the process is relatively simple and involves patching up the hole at the previous location and installing the thermostat in its new place. Patching up the hole and cutting off drywall can cost $75 to $150.

Older thermostat models may cost more to relocate. New, smart thermostats often come with remote sensors that detect temperature readings throughout the entire house, meaning you don’t need to move the main thermostat at all.

DIY Thermostat Installation vs. Hiring a Technician

If you have previously installed a thermostat or you have experience with electrical wiring, you can DIY thermostat installation and save on labor costs. A standard manual or a programmable thermostat can be easily installed by following the given instructions. Also, most smart thermostats nowadays have a simple installation process. If you don’t have to run additional wires like the C-wire, you can install most models in less than 30 minutes. To install new wires, you will have to consult a technician.

If you have no prior experience handling electric components, it is highly recommended that you seek the assistance of a licensed home thermostat installer or an HVAC pro. It’s best to leave the installation of high-voltage thermostats that deal with 120V or 240V to the professionals.
