If you have one of those old school spring coil style thermostats, it’s probably time to upgrade. Consider installing a programmable thermostat – setting a program to turn down the heating or air conditioning a few degrees while you sleep and while you’re away will save you up to 20% on your yearly heating and cooling bills.
Replacing a thermostat is a quick, simple task. Flip the breakers to turn off the power to your furnace and air conditioner unit before you get started – even though thermostats run on low voltage wiring, you don’t want to repeatedly cycle your system on and off during installation.
Remove the cover of your existing unit, and to avoid confusion take a digital picture of the wiring, or mark each wire with the appropriate letter on the terminal where it’s connected.
Disconnect the wires and remove the unit, being careful not to allow the wire to fall inside the wall – wrapping the wires around a pencil until you’ve connected the new thermostat will help.
Remove the cover from the new unit, attach it to the wall and connect the wiring (read the instructions, most wiring is colour coded and connects to the corresponding letter).
Once you’ve replaced the cover, turn the breakers back on and follow the instructions to program the system based on your needs. Your thermostat should be on an inside wall, about 5 feet off the floor, out of direct sunlight and away from large plants and drafty areas.
Now you just have to set it, and forget it!
