This guy is the best! He explains EVERYTHING. He's the first one I've found that goes through trouble shooting. Glad to have him out there.

You're right! It's not complicated! I just needed it explained clearly! Thank you so much - first time home owner, strapped for cash, and now the master of my HVAC system!

Amazing! I love folks that share their expertise and speak my language!

Wonderful video, in fact the best video. Thank you David for being thorough in your presentation.

He does a good job of explaining the details that many other videos did not share. It is easy to troubleshoot.

Thank you, so much! I changed the thermostat 2 months ago and realized that I hadn’t connected the heat element wire! I took pictures of my old thermostat and the”W” was hidden; I assumed it was the ground a wire that I didn’t need! It’s been cold this week and if it weren’t for your video , I would’ve called a someone to check our unit because the fan was working but no heat! 🙏🏼 thank you! My home is warm and cozy

You are very sincere gentleman. You love to help from bottom of your heart All respect to you!!

Thank you David, your instruction got my gas heat to work, manually, and it is heating my house. I connected the Red, Green and White and the furnace went on, great. Thank you again. I have to replace my 35 years old Programmable Robertshaw analog thermostat (battery operated quartz movement).

I did not even finish the video yet. I had to go leave a comment. This video is what people need. Thank you

David Jones may be a tradesman, but he is being a professional here. Thank you for sharing your knowledge. It really is very simple. I almost hired a service tech for an $85 service call (and that is cheap nationally).

Thank you mr. Jones at this moment I am having problems and I think it's my thermostat. Thank you for helping God bless

David you are amazing, sharing your knowledge and putting out quality vids.

Thank you you saved my butt, Trying to find a HVAC technician on Memorial Day weekend Was impossible or too expensive A little trick to hotwire for cool Save me my family from a hot weekend

Thank you Sir for video. I fixed my thermostat watching this video. Your a great service to your fellow man.

Very helpful Thank you So much was 95 today and very hot in my home After connecting the 3 wires (R, Y, G) the system finally works

Thank you so much its 16 degrees here and my thermostat went out yesterday. Got the heater going thanks to you.!

just to let you know nobody explains it so well as you do. you are a great teacher. thank you so much I'm struggling to understand this wiring.

Very good videos, I have my old thermostat & I don't like to change with the new system Cause if I have a problem I'll do manually. Thank you man

You are a god sent❤️ I understand all of this so much better because of you.

Great, I changed my thermostat very easily referring to this simple guideline, thanks David

I just want to stop by and say thank you. I'm doing a self install on a Goodman 4 ton Package unit with a new wifi thermostat. The control board told me everything was working properly but the fan would not engage. So I followed your direction (testing) and sure enough it was a bad brand new thermostat..Now I get $100 back on the return and paid $27 for a different non wifi thermostat. Once again thank you..

Very helpful. Will watch over and over till its branded in my mind. Thank you sir.

Great Video. It is nice to know that so many viewers picked up on the "Missing Orange Wire" in the cooling section. I take it that most unit's reversing valves come in the "Heat Position." Just trying to learn a little bit about the workings of a heat/cooling pump. FR

Thank you! I’ve been looking for these simple answers for 2 weeks now! So glad someone finally explained how it all works in a way that makes sense to people that are not HVAC trained.

Thanks! for showing the actual part the wire goes to...Very Educational.

Very informative and useful for the homeowners... thank you for parting with your knowledge and know how 👍🏼

Beautiful, crystal clear, very useful explanation, many many thanks and well done

Thank you So much was 102 today and very hot in my home $120.00 for a new Thermostate your video helped me out Thank you for caring to share. Hot California

I was freezing cold in my house trying to get my thermostat to work. This video got my thermostat working again! Thanks for educating me!

One of the best videos on HVAC controls.

Awesome video and explanation Mr. Jones! I'm a routine follower of yours. Thanks for the time and effort to teach the new generation.

Great video! None of Honeywell's documentation explained what letters are what on the back of their thermostat. This video helped me out greatly, thank you.

Great instructions, this helped and got me back running. Thanks

Thank you David, very easy to understand and straight forward videos. I am trying to troubleshoot Goodman heat pump. Now I am equipped with some good first troubleshooting steps for my handyman to execute. You right it’s not rocket science, but many folks struggle to understand it all, simply because there are so many components in a heat pump. I think you simplified them quiet a bit for sure. There are other things as well such as pressure switches etc, but overall I think this video is solid. I like it... tomorrow I will be doing some pressure testing along with evacuation procedure and some thermostat troubleshooting. Note I am just home owner not HVAC tech. I was thinking now that I run my whole house on solar, maybe I will also install heat strip.... or maybe my 2nd stage heat... or should I say 3rd.... I have radiators in my house heating up my house with tankless water heater.... I wonder if I can hook up my thermostat to all 3 things.... heat strip.... and my tankless water heater..... I want to achieve the following.... by default heat pump heating my house with forced air... then if it gets cold... heat strip comes on.... then if it gets super cold.... my tankless water heater turns on.... Note my tankless water heater uses gas which is cheaper than electricity ....however I got solar panels now... so I don’t care about electricity usage anymore.... hence by default I want to use heat pump forced air.... and only have tankless gas water heater heated radiators to come on only if it’s a lot colder below 32 degrees for example.... So do I just hook up my tankless water heater as the second stage to w2 wire? I am a bit confused... I don’t want my heat boiler to work when my heat pump is working, and want it to turn on automatically.... when it’s colder than 32 degrees.... I kind of like strip heat since it gives immediate satisfaction as well.... when it comes to forced air.... but I don’t want to operate on it for a long time.... Only initially just to give me initial quick heating satisfaction in my 1500 square foot home.... but then have itself turn off automatically when it gets warmer and boiler used instead.... Is it even possible to do? Or am I way overboard here? Maybe I should use if this then that automation with Alexa integrated feature to program tankless water heater to turn on while having heat pump turned off.... I haven’t wrapped my mind around all of this yet.... if you have any suggestions let me know. Thank You so much.

Thank you so much for making it so clear for us DIY guy.

I am 3 months in to the a.c trade learning to become better at my job thank you so much I will learn and apply this thank you Mr jones

I’m trying to join the hvac industry and this helps a lot simply put together for me to understand without trying to go crazy into hvac terms thanks I agree picture save you also looking up what the wire & letter means cause it might not be the same color wire thanks

Thank you for sharing.Great help.God bless you,

The way you explain is so awesome. Love all the pieces to the pie being shown

Best straight forward video I have seen to date. Thank you sir

Best vid I have seen. Wish you had mentioned Rheem and Ruud and where to connect reversing valve wire (normally orange) since their reversing valve works backwards from other mfg. In other mfg heat pumps it energizes the reversing valve in the cooling mode but with Rheem and Ruud it energizes the reversing valve in the heating mode.

Great job of explaining everything. Easy to follow your instructions

Great video. The only 1 I could find that explained the orange wire and the "O" on the mounting plate. Thanks

Excellent troubleshooting skills and examples on how to do it thanks so much I really enjoyed it

Excellent work and would say very detailed explanation for DIY home owners. Can see real honesty..... David thanks for saving us from crook technician s

Couldn't figure out what my S wires are for but you did help troubleshoot my heat pump issue! lol Thanks for the video!

Buddy excellent.... video you explain things very well,👍👏

Saved my butt big time! Thank you so much for this video

Thanks for the diagram. I am pretty knowledgeable in remodeling and some light troubleshooting with furnaces. My house has a heat pump system with a thermostat that could be used on the Starship Enterprise. (To technical) so I changed it, nothing.. changed it back per your video. BOOM. it works again. I guess I'll leave the Star Trek thermostat hooked up for now.

An excellent video. it was so informative!

When you gain experience over the years you becomes the godfather in what you doing,this is what the video said beside the wiring. thanks and thumbs up..

One of the best and most helpful video i have seen..thank you so much to make such video....Good job sir🖒
