You are amazing explaining everything about Hvac way way way much better than our teacher on class. I wish you the best man I wish you would be close to all my partners students. Best I can do is share your channel with everybody. I can thank you so much.
It would be great to see a video on how to check how accurate the thermostat reading on the display is, and whether the built-in offset adjustment needs to be configured.

Another great video, Sir. I now am sure that, I am able to trouble shoot the low voLtage circuit, because of you. i actually was able to understand you fully, because of the thoroughness you provided. I doubt it very much, that any one else out there could have explained this with such clarity. Thanks a million. I am in retirement, and I am now positive that I will be able to make some extra income, because of you. Been on a fix income, and barely making ends meet, I now will be able to service heat pumps for friends and relatives, and make some extra money. I thank you from the bottom of my heart SIR. God bless you.
Thanks for the tutorial, Mike. What would happen if 2 thermostats were spliced together (Rh+Rh/W+W) and connected to a furnace? Would both be able to call for heat independently?
Thank you! Greatly appreciated. I have the same honeywell tstat and the fan comes on in heating and cooling modes. But when trying to turn on in just fan only on or circulation modes, the fan does not come on. How do I test to see if that is a tstat issue? Thank you!
thank you Mike. my hvac unit has a nest tstat but i only have a red wire attached to one of my rc/rh terminals. but i have heat or air hows that possible if i only have one red wire attached to only one r terminal? i may have missed my answer in the video.
Hey again. I wish there was a way to directly message you. I'm still having some issues with my heat, and I need to try to replace the thermostat, or just return it could you please help me figure out how to connect this thermostat from the old mercury one? And potentially do some basic trouble shooting? I'd greatly appreciate it, thanks
That would work if there was 1 wire in the R terminal but here was not. There was 2 wires in 1 terminal then a jumper on top of that from R to Rh. It had no power to ac with only 1 wire in R.
My in-laws a/c system went down. I discovered that the BACKPLATE for the nest shorted out. this caused the contactor coil to burn out , the fan to stay on and the 3-amp fuse to blow. I removed all the wires from the backplate and everything was fine. New backplate.
For the style that completely pulls off the wall and runs on batteries, can't you test the thermostat itself directly by calling for heat or cool and probing the contacts for continuity? Instead of jumpering the wires in the wall.
@JerseyMikeHVAC wouldn't you still have to shut off power if you pull the front piece off to get to the wires behind the wall? After the thermostat is disconnected, it can be tested independently, as long as it is battery powered.
@JerseyMikeHVAC I think you misunderstood. The thermostat needs to be pulled off the wall to access the thermostat wires going to the air handler so you can jump them if that is the plan. Correct? Now once the thermostat main unit is in your hand, you can test it on a table with no regard to a system or line voltage *if it runs on battery power* .Correct? It's just a fancy switch that you can test like any other switch.
@@realSamAndrew If the thermostat is designed for that then sure. I just assume in practicality the thermostat is being tested because something isn't working. Jumpering will tell you right away if it's a system problem or a likely stat problem. But there's no rule it has to be done a certain way. If you want to test the stat on the table then that's fine.
For a beginner like myself, another great video that makes things so simple to understand.. Keep the videos coming professor!
What an amazing and informative video. Thank you sir.

Thank you! You're very welcome.
🔥💯 OUTSTANDING video and demonstration 💯🔥 Thanks for showing the step by step of this. 🔥 Keep these videos coming. 💯
Very well explained. Good teacher
Thank you.
Awesome video very thorough and detailed. Thank you.
You're welcome.
Great video Mike. Thank you for the knowledge.
You're welcome

This is the best video I’ve ever seen regarding of thermostat testing you answered all my questions .. thank you 😊
You are welcome!
Thanks Mike keep up the great work brother 👍🫡
Great teaching on thermostat👍🏼😎
Awesome!!!
Great info. Thanks Mike.
Excelente video. Thank you.
Thanks for the tutorial, Mike. What would happen if 2 thermostats were spliced together (Rh+Rh/W+W) and connected to a furnace? Would both be able to call for heat independently?
Yes they would, but either one calling will heat the entire house and not just the vicinity of each individual thermostat.
Great Video 👍
That's fantastic
Thank you! Greatly appreciated. I have the same honeywell tstat and the fan comes on in heating and cooling modes. But when trying to turn on in just fan only on or circulation modes, the fan does not come on. How do I test to see if that is a tstat issue? Thank you!
Jumper R to G. If the fan comes on that way but not in the ON position without the jumper, it's the thermostat.
thank you Mike. my hvac unit has a nest tstat but i only have a red wire attached to one of my rc/rh terminals. but i have heat or air hows that possible if i only have one red wire attached to only one r terminal? i may have missed my answer in the video.
Smart thermostats have an internal jumper, so can power heating or cooling mode from a single low voltage power source.

Is there a video for install nest when there are 2 wires in R spot & then a jumper wire from R to Rc?
If there is a jumper from R to Rc then both R terminals are treated like a single R terminal.
That would work if there was 1 wire in the R terminal but here was not. There was 2 wires in 1 terminal then a jumper on top of that from R to Rh. It had no power to ac with only 1 wire in R.

Yes, you can do that too, but that requires shutting the power off.

@@realSamAndrew No, you still have power on the wires and terminals. Battery just operates the switching.
