Upgrading to a smart thermostat can significantly enhance your home’s comfort and reduce your energy bills. This guide will give you information on how professionals set it up, giving you complete control over your home’s climate from anywhere.
Smart Thermostat Installation: Before You Get Started
Learning what a smart thermostat is is exciting, but before you dive right into the installation process, there are a few things you need to have in order. Before thinking about DIY, there are risks to consider, such as damaging your equipment, short-circuiting your whole HVAC system, or experiencing electrical shock. It is always best to enlist a professional for this kind of work to avoid any possible hazards.
Professionals work to ensure that your smart thermostat works with your AC unit and existing wiring. Some smart thermostats will not work with two-stage heat pump systems, so confirm that yours is compatible and does not need additional wiring like a C-terminal.
The “C-terminal” or common wire provides continuous power to your new device. If your older home doesn’t have one, you might need an adapter kit to make things function smoothly. Checking your system’s manual right now will save you a massive headache later on.
Step 1: Turn Off Your AC Unit
The first step to installing your new smart thermostat involves shutting off your AC unit.
- Turn the AC Off at the Breaker Panel: Turn your AC off at the breaker panel, so that there is no risk that you will accidentally short the electrical components of the system.
- Turn the System Off at the Thermostat: Turn the system off at the thermostat as well and listen to be sure that your system is not actually running.
If your breaker box isn’t clearly labeled, look for the main switch that controls your heavy HVAC equipment. Safety is always the absolute top priority when dealing with household electricity, especially if you’re unfamiliar with what a smart thermostat is or looks like. You want complete silence from your vents before moving forward.
Step 2: Remove The Faceplate And Backplate
Next, we’ll get a look at the wiring underneath.
- Remove the Faceplate: Remove the faceplate from your old thermostat. With a bit of effort, this should pop right off the wall, but don’t force it since there may be some hidden screws holding it in place! Gently wiggle the plastic cover to see where the resistance is coming from so you do not accidentally snap any fragile clips.
- Take a Photo of the Wiring: Once you have removed the faceplate, take a photo of the wiring so you know which wires connect to which terminals on the thermostat. Having that quick picture saved on your phone is the ultimate cheat code for remembering exactly where everything goes.
- Place Wire Labels: If your new Bluetooth thermostat came with wire labels, be sure to use them before you disconnect the wires.
- Remove the Backplate: Now you must remove the backplate, which typically requires a screwdriver to remove the screws holding it in place.
- (Optional) Add a C-Wire: At this point, you may need to add a C-wire if your system does not already have one, since it is generally required to provide power to your smart thermostat.
- Use Tape to Secure the Wires: When you pull the backplate away, grab a piece of tape to gently secure the dangling wires to your wall. You definitely do not want those tiny cords slipping backward into the dark drywall cavity!
Step 3: Install The New Backplate And Reconnect The Wires
The third step is to secure the new thermostat’s backplate onto the wall.
- Pull the Wires Through the Backplate: Pull the wires through the new backplate before you screw it into the wall! It really helps to use a small bubble level during this step to make sure the plate is perfectly straight. A crooked digital screen hanging on your living room wall will drive you crazy every time you walk past it.
- Connect the Wires: After it has been securely attached, connect the wires to the new terminals on the smart thermostat. Use the photo you took for guidance, or the labels you attached in step number 2. Push the exposed wire ends gently into their correct slots until you feel them click securely into place.
Step 4: Set Up The New Faceplate And Connect To Wi-Fi
The last step in how to install a smart thermostat is to set up the new faceplate and connect it to Wi-Fi.
- Replace the Faceplate: Now that the wiring is connected, you should be able to simply snap the new faceplate onto the wall. Be careful to tuck the wires back into the wall before forcing the faceplate on.
- Turn on the HVAC Breaker: As soon as the faceplate is in place, you can turn on your HVAC breaker. This should kick the power back on and allow the smart thermostat to boot up.
- Follow the On-Screen Prompts: Turning the system on will likely lead you to a series of prompts that will walk you through connecting to Wi-Fi and setting up the app on your smartphone. These steps will vary depending on the type of smart thermostat you chose, so be sure to follow those instructions accordingly.
- Set Up Your Schedules: Once the companion app is finally downloaded, you can set your heating and cooling schedules right from the couch.
The Risks Of DIY Thermostat Installation
Taking the DIY route can be fun, but electrical projects always carry certain hidden dangers. If you feel hesitant at any point during the installation, stopping is the absolute smartest choice you can make. Knowing your limits is a huge part of being a safe and responsible homeowner. Here are a few major risks to keep in mind as you learn about what a smart thermostat is and smart thermostat installation.
Serious Electrical Damage
Your home’s wiring is highly sensitive. Crossing the wrong colored wires can easily fry the delicate internal components of your brand-new digital gadget.
Miswiring Can Damage HVAC Systems
A single misplaced connection might continuously run your heat pump or burn out your AC compressor. That minor setup mistake can quickly turn into a massive, unexpected equipment replacement bill.
Shock and Fire Hazards
Working with live electricity is never a joke. Failing to properly shut off the correct breaker switch creates a severe risk of painful electrocution or electrical fires sparking inside your walls.
