Installing a furnace thermostat

Before starting the installation process, turn off the power to the furnace and call an electrician to inspect your wiring.

You can install a new furnace thermostat by accessing the furnace’s control box from the basement or outside your home.

Furnace thermostats are designed to turn the furnace’s heating system on and off as needed. Installing a new thermostat will save money on heating bills and may even reduce your carbon footprint.

Installing a new furnace thermostat is easy and can be done by anyone handy with tools. All you need are a few basic tools, patience, and about an hour to do the job right.

Here are some steps to installing a furnace thermostat.

  1. Inspect the wall where the furnace is and find out if there is any pre-existing wiring for your thermostat. If there is, bypass it and start step two. If not, proceed with step two.
  2. Determine the type of connector you need for your particular thermostat [ex: wire nut, ring terminal set].
  3. Connect the wires in the right order corresponding to your connector type [ex: black wire connects to red terminal]
  4. Ensure that your wires are securely connected by tightening them with pliers
