To get started, prepare your tools. This is a simple DIY project that only requires some tape and screwdriver. You are encouraged to use your favorite screwdriver since it is the tool you are going to use the most. You are also going to need something to label the wires.

Before you begin any home imstallation, stay safety.You must ensure that power is turned off,cut off all your home power.
With your screwdriver, just remove the old thermotat's back plate like Nest or Sensi wall plate. You will unscrew the thermostat's mounting screws. Then, remove the whole thermostat.
The masking tape also comes in handy to help you prevent the wires from falling behind the wall. You might consider taping them to the wall or into the wall cavity.
Now, remove the old thermostat's base by loosening its mounting screws. Next, take your new thermostat and separate the base from its front plate. You are ready to install the base. Ensure that you thread the low-voltage wires through the correct slots on the base.
Some new thermostats are self-leveling. If yours does not do this, use your level to make sure the base is straight and well-aligned. Then, you are ready to mount and screw it into the wall. The low-voltage wires need to be connected to the correct terminals on the base.
If you find that the connections do not match, consult your new thermostat's manual. There will be a diagram in there that provides additional help. Loose wires must be tightened. Double-check that all sheathing is still in good condition.
There are new thermostats that require batteries. If yours is one of them, insert the batteries in the correct slots. Double-check that you have matched them correctly according to their polarity.
Since thermostat wiring is electrical, you do need to be mindful of the current wiring's voltage. Then, you need to take into account the voltage specified by the manufacturer of your new thermostat. For safety reasons, your new thermostat should not exceed your wire's current capacity. Eventually, this can cause damage that could lead to shock and that could easily lead to a fire hazard.
Gently push the excess wires into the wall. The hole should be plugged with material that is fire-resistant. It is important to prevent drafts because they can affect the thermostat's operation. Fiberglass insulation is one recommendation.
Mount the control unit to the base. Secure it with the screws. Tighten as necessary.
Now, you can turn the HVAC's power back on from the main panel. Hit reset on the unit. Next, program your thermostat according to the manufacturer's instructions that were included in the packaging.
Next, test the thermostat and adjust the temperature. Your goal is to make sure that the thermostat and HVAC unit are cycling correctly. If they do not, you can always consult with a professional.
