  1. Brad Cook, you have a point, however what if the wiring setup was different and the wire colors didn't match the marks on the thermostat or were all one color?  Then marking the wires with what letter they were supposed to go on the thermostat would be really useful.

  2. The most help I've received from Home Depot. I still won't buy a thermostat there after how I was treated on delivery by the manager in Bozeman. They've lost my business, but I'll take their assistance.

  3. Thank you so much for this video! I am by no means a 'handy' person. but this was so easy to follow and I got my new programmable thermostat hooked up in no time 🙂 only thing i didnt have was a drill to make holes, but i still managed 🙂

  4. If the thermostat has already been removed/disconnected, you can open the front cover on your air handler. This is where the blower motor and circuit board is located. There you will find the other end of the control wiring connected to a board. Look at which letter symbol each wire is connected to and replicate at your thermostat…….. Or hire a professional.

  5. What if the wires are already disconnected when you go to change the thermostat? Do they carry enough voltage to damage the new thermostat should they not be matched up to the correct colours?

  6. This is a pretty straightforward and helpful video. One thing that I've noticed in this video and in a similar one from Lowe's, is that they mark the wires with alphabetic tags. Why? The letters correspond to the colors. Y is Yellow, R is Red and so on. I don't see the point of that extra step.

  7. @Dablkwid0w2008 I turned mine down too far, and it snapped right off. I found that by taking the cover off, I can manually turn the dial…but I have no idea what the temperature setting is. Time to switch it per this video. I had the old mechanical dial, and it would be nice to have a programmable one that turns on while I am still comfy cozy under the covers about 10 minutes before getting up for my shower.

  8. Nice video, I happen to have a similar old model. BUT try to find a thermostat made in USA. I didn't at either HD or Lowes. And some had energy star logo & some didn't despite being same models.

  10. last time i tried to install one of these i forgot to mark the wires……long story short….carrier guys came out and installed a new system cause i shorted out something major! old units were 15 years old anyways….live and learn.

  11. I would have left the old thermostat. I have a regular non programmable thermostat. When I get up, I turn the heat up, when I leave, I turn it down. When I get home, I turn it back up, then back down when I go to bed. I am saving money, and saving even more because I am not spending MORE money on a programmable thermostat that is not needed.

  12. Nice, you may want to mention that you don't really need to double-check the wires for voltage (extra safety check) after turning off your AC and Heat….because it's only 24V which won't hurt you…I believe I'm correct on this right? I was going to double-check to make sure the wires were safe with a multimeter but I guess you don't need to in this case (I don't know jack about electricity)

  13. Great video! My wife and I are installing our own programmable thermostat this evening and this really helped.

    Question though. Did you keep the tape, which marked the letter code of the corresponding terminal, attached after installing the new base plate of the programmable thermostat?
