Even smart thermostats occasionally need replacement—because the increased comfort they provide and energy savings make it worthwhile. What are the common steps to take if you need a replacement?

Smart thermostats help homeowners save energy and manage heating and cooling more easily. If you want to upgrade your thermostat or need help with one, this guide will explain the basics and suggest options for getting support.

Benefits of a Smart Thermostat

A smart thermostat makes it easier to save energy and keep your home comfortable. It adjusts to your daily routine, reducing electricity use while maintaining the right temperature. 
You can control it through a smartphone app, whether you’re at work or away from home. It also requires fewer manual changes. With features like scheduling and energy reports, it simplifies managing your home’s heating and cooling.

Smart Thermostat Installation

If you’re ready to replace your old thermostat or set up a new one for the first time, here’s an overview of the installation process:

1. Turn Off the Power to Your HVAC System

Safety is the top priority when working with wiring. Begin by shutting off the power to your heating, ventilation, and air conditioning system at the circuit breaker.

2. Remove the Existing Thermostat

Take off your old thermostat, making sure to label the wires as you disconnect them. This makes connecting the new one easier and avoids confusion about where each wire goes. The necessary tools are no more complicated than those needed for replacing outlets.

3. Confirm Wiring Compatibility

Smart thermostats often require a constant power source, known as a C-wire. If your system doesn’t have one, you might need a C-wire installation or select a thermostat model that works without it. Older systems, like boilers, may also require unique configurations, such as thermostat wiring for boilers or furnaces. 

Tip: if you're unsure about electrical work, it's best to call a professional.

4. Install Your New Thermostat

Follow the specific instructions for your smart thermostat. This typically involves mounting the new base plate, attaching the wiring correctly—whether it’s for a heat pump, furnace, or boiler—and fixing the thermostat securely on the wall. No more complicated than replacing an outlet or a switch.

5. Set Up the Device

After connecting everything, turn the power on and set up your thermostat. Connect it to Wi-Fi and use the app to enable mobile features. Your thermostat is now ready to use.

Need Help?

Wiring and setup can be tricky, especially with advanced HVAC systems. If this feels overwhelming, a thermostat installation service or a skilled handyman can handle the process smoothly.

Why Professional Help Makes a Difference

Some homeowners may handle thermostat wiring on their own, but systems like heat pump wiring or adding a C-wire are best left to professionals. Incorrect wiring can damage your equipment or cause connection issues. Without the right skills, installing a thermostat can also take a lot of time and effort. 

If you’re not comfortable with DIY work, hiring a skilled handyman can ensure the job is done correctly. FixHome+ offers reliable thermostat installation services in Chicago and nearby areas. Our handymen can help with installations, repairs, and upgrades to meet your needs.
