What about if its partially stuck closed but works devent attached to the liquid line

Bad capacitor damaged the blower!!! Thank you for the info.

why he isolated the water pipe ?

what's the deferens between vacuum gauge and the green tool ?

How important is it for the sensing bulb to be insulated? I seen some manufacturers don’t insulated the sensing bulb and some do

My dog watched this video with me and I think now he wants to be a blogger too🐱

How do you install surge protector do you have link for it ?

Oh that dang condensate trap..Got me one year before I found your channel..Stumbled upon it by guessing..Great vid..Keep 'em coming..

I have a straight cool system with electric heat strips. Which part from the electric heat can create a short in my condenser contactor? Outside condensing contactor was having an electric short and went away when heater was disconnected. This happened during cooling mode. Thanks in advance for your support.

Scam.

So we have to go to that Compressor manufacturer's website to find out the MFD rating? There is no other way to find that out? I mean if we use the Start Capacitor formula with input Electrical load it won’t show appropriate Capacitor rating?

hey ac what advice can you give a 25 year old that is 50% done with a hvac degree but took time off, and is now scared to return? I just feel like im very behind due to the time away and im a bit scared.

Recovery tanks are cute idea. BUT when you're recovering R410a or R454b on a leaking evap changeout. Then when you take you're full tank for exchange, the supplier checks that Freon & Charges you a huge fee to dispose Freon bc it's NOT Pure.

How many amps (at 0.75v) do you think a powerpile will generate? Or, how many ohms do you think it could overcome? Thank you!

I love all your content and frequently share it within my small circle. Do you have a video on your acid burnout procedure? I recently had an extremely acidic system. I did one of the qwik acid tests and I had never seen such an aggressive reaction. I obtained another sample and bench-tested it to be 1.5ph. Near battery acid. I recommend the homeowner do a full change out including lineset but they chose another contractor to repair the system. I fear they will be spending a lot more down the line. I digress; love the content keep it up!

Hot water is coming up thru the return line instead of the supply hot water line out of the boiler?

Craig is there an updated workbook coming out with this? Id really like to be able to purchase the workbook and reference cards with it! thanks for all you do

Can you pack the dough dope to prevent bugs and wasps around compressor covers from getting in

Little mini furnace

42 year old female here 2nd semester starts tomorrow. I need loads of 🙏 prayers! I’m loving HVAC very fascinating. Now for someone to interview me. Give me a job and let me serve the people. Also paying bills is ideal. 😂🤣😂🤪

The majority of hvac schools these days are complete trash. I’m so great-full for people like you who educate newcomers like myself.

Just clean it with sandpaper and wipe it off on your shirt once you’re done

Awesome

If anyone is here with the same problem I had. Honeywell Sv9541 gas valve does control the ignition sequence. If you are having inducer motor not turn on or flame its the gas valve and it may have a solid green light showing. I replaced control board first and it didnt fix issue.

There is literally no reason why a young tech if they enjoy the field and are interested in a career, to not watch videos like this to learn everything they can. I wish tools like KZbin existed when I was in school.

Perfect..exactly what I was looking for..and exactly that same unit.. Perfect explanation..thanks

Might I suggest starting out with a block diagram/ schematic of the system? The logic should be simple to explain but this tends to throw out a bunch of facts and bouncing around different points without connecting the points. At least on old Trane XL90 furnaces, there is no modulating valve to drain the condensate but rather, a simple dip leg partially filled with water to ensure condensate flows to the drain and is not instead being sucked up into the condensing tubes and into the flue/ exhaust line.

the video is only 6 minutes long,but in my case it's about a whole week.

Where do I get/ how do I make the bleed resister you used for the capacitor?

In regions where temperature can soar above 110 degrees fahrenheit, how will you get the compressor to raise vapor pressure and temperature for condensation to occur?

I was trained in 06-07 and this is all they trained us on. We got out in the field and didn’t see old contacts everyday and saw cube relays and button switches, it was like they trained us for the 70-80s and still have no idea why they’re so behind. Hope they got with the times.

Love it!! ¿Cuándo más contenido en español? Gracias por tu labor

can anybody say why he is not turning gas bottle upside down to get gas instead of liquid out of bottle?

Why would you insulate or not insulate that duct? If u were going to insulate, do it on the ground or after it's up?

If doing a video to inform or share info do NOT spit your words out as fast as you can.

Ya know.. while i appreciate this. There are so many units and systems out there and over time have changed... that for us to understand what we are poking at when you explain.. lol... is not quite going to happen. Mine is pretty old too, that i dont know its efficiency or year made, metal nameplate has info for it but no brand. Tho a model number, HG100U3. Im interested in possibly replacing, in case its very old and inefficient. If standard 80% id leave perhaps.. but if not, id change. Either way, i dont know quite how to clean or what im looking at it either. Like i said, so many factors and differences. Mine isnt exactly like that, to follow. How would you suggest understanding it more, where to find a possible manual and also, how much savings between each units? Lets say i had an 80%, so if i got to 90%, is that a 10% savings per month off my bill, would you say? Is it more? How do we understand that too. I know the larger the. Nunber its more efficient etc but what about savings? Lets say its 100$ a month for the 80% and i got 90%, its 1/9 better so does that mean maybe like 9-10% savings, so lets say $90 it would have been? Or am i missing something trying to understanding the savings as well?

Thank you for this. When I went to trade school my instructor used to show me ac service tech videos and here I am now years later starting my first instructor job and I get to teach my own class at a private college in march!

Thank you for all your videos! I'm a long time subscriber. Since the high speed has less resistance would this mean less current and would this also result in using less electricity in the long run? Also what would be the most efficient blower motor available if I were to replace my 20 year old motor on a 3.5 ton Trane? Thanks for all the good info. You are the best!

Keep it up man! Your videos are essential to younger techs and serve as great reminders for the seasoned guys.

In PA where I live these are considered new technology.

You’re the best as always, Craig! We just had a problem the other day with the controls on a hot water heater, and of course you give the best explanation. It is not exactly confirmed what is the problem is. I will check back to review the videos again. And I love the way you have the parts we are talking about taking out of the equipment so we get a better view and understanding of them. Thanks for all your help

They’re cheap. Just install a new one and never have to say you’re sorry again

لطفاً زیر نویس فارسی هم اضافه کنید ممنون از شما دوست عزیز ❤

Remember those from YEARS ago!!
