Step 1: Start by choosing a good thermostat

The process of installing a good thermostat for your home should start at the departmental store. Here, start by selecting a thermostat that is not just cost friendly and easy to install but also highly efficient if you want it to serve you for a long time.

Step 2: Power the HVAC system off and disconnect the old thermostat

Once you have the right thermostat and the right tools including a screwdriver, drill as well as a level, power off the heating system and start disconnecting the old thermostat. Start by removing the control cover for the existing thermostat to gain access to the wiring plate.

Note that this plate contains two different sets of wires; from the furnace and electric power. Take note of their connection ports; you might want to take a picture of it for reference, before disconnecting them. Then go ahead and label or mark them accordingly.

Step 3: Remove old plate and install new one

Unplug the old thermostat from the wall. Then unscrew the power cables from the thermostat and using a masking tape, stick them on the wall to prevent them from slipping away through the wall cavity. Ensure that you take note of the high voltage power cable to avoid fixing it wrongly with the new thermostat.

Step 4: Level the new thermostat plate against the wall

Before fixing the new plate, consider the strength of the anchors on which the previous thermostat rested. Whatever the result, however, it is only wise that you drill new positions for the thermostat anchors you are to install keeping in mind the length of its mounting screws.

While mounting the plate, use a level to ensure that it is a balanced as possible for maximum efficiency. To reduce the confusion, especially with the mounting of wires, it is critical that you maintain the same position occupied by the old thermostat in fixing the new one.

How To Connect The Wires

Step 5: Connecting the wires 

This is the single most crucial step that the installer should remain conscious of when it comes to installing a thermostat. If wrongly connected, at the very least, the thermostat won’t work. Depending on the type of connection and the thermostat brand, an error in the connection may even end up destroying the device forcing you to incur yet another purchase cost. So how do you avoid a faulty connection?

By strictly following the connection instructions from the manufacturer that accompany the thermostat, however, ensure that you get expert help whenever you are unsure of the process. A seemingly insignificant error in the connection like improperly fixed wires would have long term implications on the efficiency of your thermostat.

Step 6: Attach the control cover and power on

The hardest part of thermostat installation lies in the wire connection and once you are done with that, you are as good as done. You can now fix the control cover on your thermostat as well as fix batteries if the model is battery powered. After switching on power to the furnace, proceed with the last step that involves setting up the installed thermostat according to the manufacturer’s instructions.

These steps not only teach you how to install a thermostat when replacing a new one with an old or inefficient one but they can also be used when installing a thermostat to a new room or building. The only problem in such a case would be identifying the right connection port for the wire cables that would most probably be hanging on the wall.

But if the furnace installers had labeled them well it would also be an easy do it yourself project. Nevertheless, even with such an extensive guide, it is always advisable that you engage a professional in one way or another especially in choosing the right thermostat and conducting an efficiency evaluation. This ensures that you not only install a thermostat that is compatible with your furnace requirements as well as ensuring that works as expected.
