How To Install A Thermostat Without An Electrician
Programmable thermostats are increasing in popularity day by day thanks to the numerous benefits they offer. This handy home addition allows you to customize and regulate the heating and cooling system of your home. In turn, this saves you energy utility costs that would be high otherwise.
A smart or programmable thermostat automatically adjusts your home's temperature based on the occupancy and the time of day. For example, during the cooling season, the house temperature can rise if no one is at home and start cooling based on the time the occupants return home. This ensures that your home is not being heated or cooled down when no one is there.
If you're still not sure if it is time to switch out your old thermostat for a smart programmable model, we will look at some benefits of having a smart thermostat. However, this article will focus on how to install a thermostat, like what tools do you need, how long it will take and so on.
Why Should You Have A Programmable Thermostat?
A programmable or smart thermostat:
- Automatically adjusts your home's heating and cooling system. This ensures that you don't have to get up and adjust the settings. For settings like turning on and off, you need to program beforehand when you would like these times to be.
- Controls home temperature, making it more effective. Regulating your home temperature based on the occupancy helps you save energy and money that would have been used to run the HVAC system in an empty house.
- Improves the lifespan and efficiency of your HVAC. By programming your HVAC into the smart thermostat, you limit its running time, making it more efficient while saving on costs. In addition, if you were planning on switching out the system, you can extend its lifespan this way.
What Do You Need to Know Before Installing A Programmable/Smart Thermostat?
- Ensure that the smart thermostat is compatible with your heating and cooling system. If you are unsure, it is advisable to call your heating and cooling contractor or utility provider.
- Inspect the existing thermostat. By checking the wires running from the furnace to the thermostat, you can determine if the current setup will work well with the new smart thermostat. If not, you may need to buy a new wire. In addition, if you are installing a non-programmable model, this process helps familiarize yourself with the thermostat wiring.
- You need to ensure that the new thermostat has a big enough faceplate to cover the hole left by the existing thermostat. To do this, measure the hole and compare the measurement with the new thermostat.
- It is essential to also check the new thermostat's compatibility with other systems, especially if you have a home security system in place. The two systems need to connect to ensure seamless use and communication. The same is with a voice assistant.
- Lastly, check the manufacturer's recommendation on installation and warranty. Will installing the thermostat on your own jeopardize the warranties? Again, this is vital information to know beforehand.

How To Install A Thermostat
Follow this step-by-step guide to remove your old thermostat and replace it with a new smart thermostat. It is easy and concise.
Step 1: Remove the Old Thermostat
Before removing the old thermostat, you need to turn off the heating and cooling system at the circuit breaker box or the main fuse. Since the old thermostat is turned off, you can proceed to take off the lid. Some thermostats will need you to be unscrewed to remove the faceplate, while others will simply pop off with a bit of pressure. Once the lid is off, leave the wall and the wires connected as they are.
Step 2: Label the Wires
This stage involves labeling the wires from the existing thermostat installation. Take a small masking tape and attach it to each wire, labeling the indicated letter where the wire attaches to the old thermostat. In addition, do not pay much attention to the wire color. This is because it is not always that the letter corresponds with the wire color.
Step 3: Take A Picture for Reference
Taking a picture of the existing thermostat wiring gives you a visual reference for the new thermostat installation.
Step 4: Disconnect the Wires
Using a screwdriver, disconnect the wires to remove the wall plate. This next step is important and will save you unnecessary frustration and aggravation. Next, wrap the existing wires with a clothespin, small screwdriver or tape them to the wall. This ensures that the wires do not retreat to the wall cavity when separated from the old thermostat.
Step 5: Remove Existing Wall Anchors
This step is important if the new thermostat has a different size and shape from the previous one. However, if they're both of equal shape and size, skip this step.
Step 6: Install the New Backplate
If you had removed the old wall anchors, use a level to mark the new drilling holes and then proceed to drill. However, before installing the thermostat mount, it is necessary to confirm the connection. If you can only see two wires connecting to your existing thermostat, the programmable thermostat is likely battery-powered. However, a direct-wired programmable thermostat will have more than two wires.
Having confirmed the wiring, it's time to install the new thermostat's backplate. At this stage, it is important to go over the manufacturer's instructions again. First, fasten the wall plate to the wall using fasteners and then secure the wires, so they do not fall back.
Step 7: Connect the Wires
Ensure to follow the instructions to the letter when connecting wires. Ideally, you will be matching the letters on the labeled wires to the letters on the new thermostat. Once you have inserted the wires into their corresponding terminals, ensure that you tighten the screw terminals. In addition, ensure that you have a C-wire for a new programmable thermostat using WiFi. However, if you have a non-programmable thermostat, this is the part of the thermostat installation where you need to connect the batteries.
Step 8: Install the Faceplate
Having completed the thermostat wiring, it is now time to install the faceplate. Again, ensure to follow instructions as per the given manual.
Step 9: Restore Power
Now turn the circuit breaker on to restore power in your home. This will also restore power to the air conditioning unit and furnace. At this point, set up the new thermostat settings according to your schedule. Most smart thermostats will have an app, so be sure to download it and regulate heating and cooling in your home from anywhere.
