From all these comments, I sure as hell hope you can't become an 'ac technician' in 6 months. A refrigeration mechanic is a years long apprenticeship like other core trades like plumbing and electrician, of which refrigeration/HVAC shares several skills/knowledge basics from.
man... i gota become an ac tech... someone in my family became a tech and worked for the court house and he got the best benefits discounts everywhere he went and is now retired in a big ass house with brand new cars and everything.... he was always an asshole and still is i cant stand him but out of all the jobs out there that are in demand this hvac business doesn't look like its going anywhere soon (cuz almost everyone has an ac its always in demand),,, uploader do you have any advice for me?

Hey i need to run 2 120vac humidifiers on individual humidstats (diy from scratch). I have a 120v 24v transformer but i need a relay that will kick the humidifiers on and off at in a cooling manner. What relay should i use
@willscomputerservice There are a couple of ways you could make this work. You could use a four pin relay with a 24 volt coil to bring on the 120 volts to the humidifier or if you're using a line voltage humidistat then you won't need a relay at all.
Hi i am goin to school in Puerto rico and im stuying rite now a ice maker.i waz seeing your videos and there preatty good. I wanted to see if you would make a video about ice makers HOW THEY WORK,TROUBLE SHOOTING THEM,AND ESPECIALY DIAGRAMAS CUZ THATS WHERE IM REALLY STUCK AT. THANKS HOPE TO HEAR FROM YOU!

Is there any books you can recommened me to study on????? I wish to learn more and i would appreciate all the help i can get thank u!!!!
DrZ, I appreciate your humbleness and your patience in presenting this information. You are very thoughtful in your presentations, and it shows. As we say in Hawaii, much mahalos (thank-you). I am just now learning the trade, and your videos are extremely helpful to not just me, but most of the guys in the class. Keep em coming, .... U da man!!
I was just wanting to know if butt conectors would be a better choice in some applications than wire nuts? I like how butt conectors make it look like a neater job than wire nuts.Thank you for your videos you post.They are a great help I recomended your videos to my classmates in the HVAC classes I attend.
Sir- You have no idea how helpful your videos have been. I'm going to school for HVAC-R and I'm having a hard time understanding diagrams. We have even watched your videos in school. Thanks a million.
@kandypaint64 Being big isn't bad as long as you're doing commercial refrigeration and air conditioning. I think that you'll find it a bit difficult to crawl around residential attics.
DrZarkloff, thantk you for suggestion! I think it would be a great service to us if you do a video showing how to do this. I suggested it when he fist came & didn't find a leak until he said it was leaking through the high pressure line valve, which he changed. But as I mentioned before it leaked freon again. I lost my trust in this technician.
DrZarkloff, thx for educating us w/ your videos. I've spent $500 & my ac is still not working. Per tech guy it's losing freon through evaporator although his leak detector doesn't detect any leak. The evaporator has never been distort and it looks very clean (almost like new), except for some rust on the sides where he thinks it's leaking. Well, since my sys is 14y old his remedy is for me to buy a new unit rather than buying another evap only under the suspicion of a leak. Your 2 cents please.
@KOxDisturbance the only "drop-in" replacement for R12 is R134a. but you must retrofit the system because of the differences in pressures and characteristics between the to refrigerants. exp. you'll need to replace the service ports on your hard lines to R134a type, evaporator, receiver/accumulater dryer etc..
Can you demonstrate how to convert an r-12 unit into a r 414 if compatible? Maybe an r 22 unit into an r 414? Since the EPA has been barring the use of these refrigerants they will need to be converted on old units unless they are just used for scrap when they become a hassle for the owners. Maybe even this new refrigerant mix can be used to replace old r12 or r22 units? Any info? Thanks in advance your videos are excellent learning tools.
@KOxDisturbance R-414b, commonly known as Hot Shot, can be used as a drop in replacement for R-12. Although, R-414b cannot be used in automotive applications because of the butane that is in R-414b. There are a couple of drop in replacements for R-22.
For starters, there's R422a for low and medium temperature applications and there's R-422d for high temperature applications. Then there's NU-22.
@DrZarkloff Thanks. Do you know what if any type of drop ins CAN be used for automotive? Also where can we locate and differentiate between "B" common with "B" energize?
@KOxDisturbance I don't know of any good drop in replacements for automotive R12. Hot Shot has Butane in it so that's out of the question. I'm not really sure about what you mean by B common or B energise.

I have a WW geotherm heat pump on which the 240 volt L2 connector is completely burnt. The unit was NOT mounted on a vibration pad nor were the compressor mounting bolts lossened as per instructions. Can loose wires or possibly just vibration cause overheating??
its very generous of you to take time to show everyone this stuff. I am not so sure most people are going to get what you are talking about but with a little training this is helpful
Could I just get a copy of your brain instead, j/k. Excellent video, Good Introduction to wiring diagrams. Sadly I only understood half of it, the real world part. 5 stars
What is the music that is playing at the beginning of your video, i went to check out the Champagne site and the music here was not on their play list.
I am a student at a Career Center in Lakeland, Florida I take the Hvac course I have only about semester & a few weeks left before I graduate, I have been learning how to wire electric boards with switches, wires, relay terminals & lightbulbs as my loads, I am now working with 4 pole double throw Ice cube relays, when I complete my program do you think I could apply for an Hvac job with that knowledge or do you think I should look in to another electric class?
Dr., i was wondering if you could do a Video or possibly give me a walkthrough on Tieing in a thermostat to the condensing unit WITHOUT a wiring Diagram, my Instructor has somewhat left me behind and i have too install a Rudd heatpump by the end of simester. and i have NO CLUE on Thermostats
hello DR.Z my furnace run on heat and thermostat is satisfy but fan keeps running checked fan relay ok,checked circuitboard and its ok,can you help me out thanx. Its a carrier
The wiring diagram is usually located on the back side of the control panel. If it's been destroyed or lost, you could probably find it at the manufacturers web site. If all else fails then try calling the manufacturer.
wow very informative, even for an electrical engineer!! I am currently working on a giant project that requires the system to externally bypass the AC unit, and I've been watching you're videos to get familiar with the terminology. I think I might have blown the 24VAC Xformer, we are going to pry open the air condenser tomorrow to check, "rheem coreter 2 ??", anyways, I was wondering if you knew if the transformer is typically protected with a fuse. Thanks!!
Thanks for watching. Most 75 VA transformers have a built-in breaker. Although 40 VA transformers usually are not protected unless precautions were taken in the field.
when hooking up a 3 ton package unit, will you need to run 240 volt line for the heat strip and a 240 volt line for the air conditioner ,one for each? or just one line for both. I see the Heat strip has a place for a 240 v line to be run to it. Thanks
It all depends on the manufacturers requirements. Most residential systems will only require 240 volts to be run to the main disconnect then whipped into the package cabinet onto a single power block. I have seen many commercial applications of the same tonnage to require separate breakers and separate leads going to separate power blocks.
so, i want don't have to run a 240 wire to the heat strip. The one 240 v line runs the Heat pump ,the air condition and the heat strip .All i have to do is, just plug the heat strip into the plug in that's by the heat strip panel, rite? Thanks great info Dr.
This video tells me that Engineers design things NOT in the 'Real World' or in 'Reality'. Hmmmm...

I am a student at a Career Center in Lakeland, Florida I take the Hvac course I have only about semester & a few weeks left before I graduate, I have been learning how to wire electric boards with switches, wires, relay terminals & lightbulbs as my loads, I am now working with 4 pole double throw Ice cube relays, when I complete my program do you think I could apply for an Hvac job with that knowledge or do you think I should look in to another electric class?

I wish you all the best. Even after you get a job, you need to continue to take HVAC classes. You can't know too much in this field.

Dr., i was wondering if you could do a Video or possibly give me a walkthrough on Tieing in a thermostat to the condensing unit WITHOUT a wiring Diagram, my Instructor has somewhat left me behind and i have too install a Rudd heatpump by the end of simester. and i have NO CLUE on Thermostats
raptorman120 2 years ago
That sounds like some great practice. A residential heat pump condensing unit will usually have as many as five control wires connected to it.
R 24 vac
C common
Y1 Compressor
O/B reversing valve
E emergency heat when defrosting.

hello DR.Z my furnace run on heat and thermostat is satisfy but fan keeps running checked fan relay ok,checked circuitboard and its ok,can you help me out thanx. Its a carrier
Danny1073 2 years ago
You might want to check out how the thermostat is setup in the heat mode. The fan will cycle only if the fan is set at the auto position.

Where can I find the wiring diagram for my particular system?
alanaldapierce 2 years ago
The wiring diagram is usually located on the back side of the control panel. If it's been destroyed or lost, you could probably find it at the manufacturers web site. If all else fails then try calling the manufacturer.

wow very informative, even for an electrical engineer!! I am currently working on a giant project that requires the system to externally bypass the AC unit, and I've been watching you're videos to get familiar with the terminology. I think I might have blown the 24VAC Xformer, we are going to pry open the air condenser tomorrow to check, "rheem coreter 2 ??", anyways, I was wondering if you knew if the transformer is typically protected with a fuse. Thanks!!
kdarrah123 2 years ago
Thanks for watching. Most 75 VA transformers have a built-in breaker. Although 40 VA transformers usually are not protected unless precautions were taken in the field.

there was a blown 3A fuse on a circuit board... replaced it and now works
kdarrah123 2 years ago
Good going. I wish the board manufactures would replace those fuses with breakers.

when hooking up a 3 ton package unit, will you need to run 240 volt line for the heat strip and a 240 volt line for the air conditioner ,one for each? or just one line for both. I see the Heat strip has a place for a 240 v line to be run to it. Thanks
fredboy1968 2 years ago
It all depends on the manufacturers requirements. Most residential systems will only require 240 volts to be run to the main disconnect then whipped into the package cabinet onto a single power block. I have seen many commercial applications of the same tonnage to require separate breakers and separate leads going to separate power blocks.
DrZarkloff 2 years ago
so, i want don't have to run a 240 wire to the heat strip. The one 240 v line runs the Heat pump ,the air condition and the heat strip .All i have to do is, just plug the heat strip into the plug in that's by the heat strip panel, rite? Thanks great info Dr.
