How to change an old thermostat

Schedule Your Thermostat Replacement

How To change an old thermostat

First, you'll need to shut off power to the thermostat. You can do this by locating your circuit breaker. This is an important step to ensure your safety.

Next, remove the screws that hold your thermostat to the wall. Pull the thermostat away from the wall. You will see a few wires that you need to address. Pay attention to how the old thermostat is wired; you may consider taking a picture.

See where the wires are connected. There should be a cable for the A/C, and also one for the water; which are attached to the thermostat's screws.

Usually, you'll see the screws marked with letters. Before you remove any wires, you'll want to cover up the wiring with masking tape. Write the letter from the screw on top of the tape.

You can use a screwdriver to loosen up the screws. Take the wires out from the screw.

Remove the mounting-plate screws and remove the thermostat from the wall surface.

Placing your New Thermostat

Your new thermostat should come with stickers. Place the stickers onto the wires. You can reference the old thermostat's wiring and check your new manual. You'll then need to loosen the terminal screws.

Place the new base over the wires and make sure it's level.

Next, drill the holes making sure to follow the directions in the manual. Place the plastic inserts into your wall.

You can then use a combination stripper to trim the wires if necessary.

Once it's connected you can activate the power back on.

Checking the Functionality

As soon as you've figured out just how to change out your old analog thermostat with a digital thermostat, you're practically prepared to go. But first, let's check to make sure it is working properly.

You can set the thermostat to your furnace. The AC will come at a different time. Let them have 5 minutes to activate. If it's not working correctly take a look at what you did and make sure no steps were missed.

At times, you may need to reset the thermostat. You should find a button that allows you to reset it.

Once you check to make sure it is functioning, you'll need to program your thermostat. This is where you need to check the manual for specific instructions, depending on your new thermostat.

A programmable thermostat is your best option to save on your electricity bill.

Emanuel came out to inspect why our commode was not flushing properly. After an inspection he describer the options. Since the commode was over 40 years old we picked the option to replace the commode with a new one. He Asked several questions about what we would like and the showed us two options. We picked the one that we liked and he obtained the commode from the ware house and installed it the same afternoon.. He completed the installation and did a great clean up of the area and answered answered all of our questions. I fully recommend Emanuel and 1-800-Plumber of Pearland
