Great video. I have both the blue and green wire connected to the C on my old iComfort thermostat. Trying to upgrade to the Nest 4th gen thermostat , can I connect green and blue wire to the C slot in the Nest thermostat or do I separate them? Thanks for your input.
Great video! I have my green and blue wire connected together in the C on my old iComfort thermostat. I’m upgrading to the Nest 4th gen thermostat, do I keep the blue and green wire connected the C slot or should I separate it? Thanks for any input .

this was very informative but I dont have an extra wire so I was going to move G to C, as explained. However, you say change it to C at the HVAC system. I have a split system so are we changing it at the heater, condensor, or both?
Excellent video in every respect. Only one situation NOT covered. How can a person install a C wire to an OLD SYSTEM NOT HAVING A MAIN MODERN MOTHERBOARD ON THE FURNACE???
Thanks a lot for the great video. I have AC (cold/hot) and there are 3 wires only. The existing thermostat has a digital screen but no back light even. Any suggestion on how can I install a smart thermostat? The AC is a split unit where there is an external unit and ceiling mounted internal unit.
When a disconnected C Wire is found at the thermostat, do you assume it’s connected at the HVAC Unit? Is there a way to determine this at the thermostat?
I'm not a professional, but I wouldn't be comfortable getting rid of my ground for any wiring (even low voltage) running through my walls. That just seems like asking for trouble.
G doesn’t mean ground in this case. There’s no “ground wire” for the thermostat - actually the C wire is closer to the typical function of a ground wire than any of the others (it’s an unloaded negative path).
@@nekkrist He was talking about the common wire. Which is the other side of 24v transformer. Common at the thermostat was not needed in old analog thermostats . They are nothing more than a set of switches switch. Hot and common to a switch goes boom. Fork in the light socket experiment proves this! Then came digital thermostats. Rather have a new wire ran a battery was enough to power the display. Now that we have fancy thermostats with wifi we need power and common or it will not be able to operate

This is the only video that answered each of my questions and explained everything so well.
Great to hear! Thanks for watching!
Thank you for the explanation, it took a long time to find out what C actually was.
Best video explaining C-Wire that I've found. Tks.

Super simple to follow thank you
Thanks for being a subscriber! I appreciate the support!
Very clear explanation. Thanks for sharing

exactly, I dislike that for that reason

Thank you, even somebody as dumb as me understood this. Very helpful!
Thanks now I know what the C wire is.
I had to log in just to like n subscribe, Great explanation, thank you so much!
Hi ,can i used first generation nest with a heat pump sistem??? If so do you have a video explaining how to install
The wires
I vaguely recall.... After moving G wire to C, don't you need a jumper wire between G terminal and Y terminal ?
excellent explanation
This was ridiculously informative, tysm
Thank you!
In case if it helps someone, if there's no C terminal on the thermostat, don't attack the blue wire to anything. Tape it and put away.
Great explanation, TY
When a disconnected C Wire is found at the thermostat, do you assume it’s connected at the HVAC Unit? Is there a way to determine this at the thermostat?
Great video, thanks.
Thank yu for the info
great video!
I would double like this video if I could
Is the C wire always blue?
Perfect explaining 🫡
C wire is like finding the G spot. 😂
My C wire is black is that okay?
