ฝัง
- เผยแพร่เมื่อ 15 มิ.ย. 2024
- A simple explanation of how a home AC ( air conditioner ) works for beginners. An air conditioner video for dummies, meaning it's not a video for technical engineers..This video is lacking in long technical words, the engineering of the AC unit, and does not explain the science of why the air conditioner system does what it does. Just a basic and easy to understand video to help better understand how a central home air conditioner works.

to some Folk that is still confused - You cannot interchange words “heat up” with "temperature rise”, and this is a big dirty secret of HVACing.
You can increase the temperature of any substance by 1) giving it actual heat; 2) by compressing it (rising its pressure). In the later case, you don’t give it any heat at all, by the temperature goes up.
After a house, the freon-gas has low temperature but lots of stored heat in it. Because it is cold it cannot give this heat out to the outside air. You must somehow increase the freon-gas temperature while not giving it any extra heat. This is done by compressing it: pressure is up, and so is the gas temperature. Now, when the freon leaves the compressor, your freon is much hotter that the outside air and it still has all that stored heat, which it got from your house. Because it is hotter that the outside air, it will give this stored heat to the outside air. And it will become liquid with the temperature about that of the outside air. Remember this.
Now, this liquid goes back to your house. But your house is cooler than this liquid because the house temperature (under normal operation of an VAC unit) is less than the temperature of the outside air. So, the liquid cannot take any heat from your house. What do you do? You decompress the liquid, and it will become vapor/gas. You continue to decompress (that is why your have that metering device) and that freon-gas becomes cooler and cooler, and its temperature drops below the house temperature. At this point the house heat can flow into that vapor/gas. So, observe an interesting situation, the gas gets colder because it is decompressed, but because it is cold, the heat from house flows into it (so if a decompression rate is higher than the heat flow rate, your freon will take heat but it will still get cold. Ain’t that fun?). In other words, the freon takes heat from your house and stores it, and … goes back to the compressor. This vicious cycle of heat transfer and pressure drop/rises repeats and repeats. Ho!
Thank you for explaining this cycle so thoroughly 👌🏼
This is hands down the best explanation bro, thank you.
So, you don't change the temperature, you change the pressure. If you want a higher temperature, increase the pressure using a compressor pump. If you want a lower temperature, decrease the pressure using an expansion valve.
@@Roconnell95 this is hands down the worst explanation. It's not even accurate. And it's more confusing than anything.
@@josephherron7671 lol i agree
I have to say this is the best explanation of how air conditioning works put into layman's terms I have ever heard. You truly have an ability that most don't. Thank-you for taking the time to explain this to people. You have undoubtedly helped many. You got my subscription.
Disclaimer: anyone watching this is already in the category of not a dummy. 😊 I added the dummy part to the video title simply to stress that this is not a highly technical video.
You are the best :) Thanks
Anybody who thinks they’re not a dummy hasn’t learned enough yet. The more I learn, the greater the dummy I realize I am. I have a long way to go.
@@oceantiara Thank you RosAnn but actually... YOU are the best! :) Thanks for watching and commenting!
@Schlau Urheber You make a very good point. Thank you for explaining the correct way to look at this!
@@holtrussell Well said Holt! We are all dummies in one thing or another, learning new things every day.
Daily viewer here... Please do more “for dummies” videos.. like a whoooole playlist
Haha glad you liked the video! Thank you! I will keep that in mind going forward :)
Specifically, I am interested in this one: Refrigerator Maintenance. What, if anything, should a person do to maximize functioning/longevity of their fridge? Should you restart every so often? If so, how and how often?
please do a video on heat pumps, thermostats, defrost cycles!
Bro, I'm a 4th year mechanical engineering student and I'm learning more from you than my professors.... I should be paying you for my Advanced Thermo class :)
HVAC student here: well done sir, you really tie in what I learn at school with your videos. Keep up the great work!
U liking it so fare ?
@@larrytheplumber9851 YES. Best decision of my life
Just want to say thanks for all your videos! I'm an electrical engineer but I've used your videos to repair my refrigerator (bad starter relay), my furnace (no inlet pressure on the pressure switches due to cracked hose), and installed a best thermostat. Really goes to show that practical knowledge beats theoretical in the real world!
Great video!! Excellent and thorough explanation.
That's very helpful. I've watched a dozen videos and you explained the best by far. Thanks.
This video is awesome. I never knew exactly how an ac worked until now. I only a vague idea before this video. That, which you spoke of, makes all kinds of sense. Thank you very much. Thank you.
Best explanation i have heard. The A/C concept has always been hard for me to grasp but I think I finally got it. Thank you.
Fantastic vid! I'm HVAC contractor.
Just explained Thermodynamics in less than 9 minutes better than most college courses.
Except that it is over simplified! The functions of the compressor and evaporator are exactly what their names suggest. The compressor compresses the air and with the help of the condenser turns the freon into the liquid form. In this processor heat is dissipated. The fan sucks out this hot air created by the compression from around the compressor because you don't want the compressor to overheat. In the evaporator this liquid absorbs the heat from the surrounding and evaporates thereof creating cold air around the coil.
More videos like this would be greatly appreciated. I like being able to know and identify things, especially when it comes to repairs and knowing the exact function of each part. Thanks, Jay!
You made the process of AC so much more understandable for me...THANKS!
We stumbled upon your channel last month when looking for installation info on a Honeywell thermostat and I was blown away by your content and selfless videos.
Thank you for consistantly helping the masses and explaining everything in terms that all can understand..
Much thanks again👍
That's great to hear, glad that my videos have been helpful! I appreciate the comment!
By the way, that is a pretty sweet username :)
I’ve been binge watching HVAC/R fundamentals/basics to get myself into the HVAC field and know a bit more than I did, I am forever grateful for videos like this, thank you!
This gentleman is absolutely a genius. Highly recommend his content will save you thousands in the long run. Thank you!
Awesome explanation. I like that you started with explaining the basic law of heat transfer. From there, everything started to make sense!
I took some A/C courses at the local JC. I understand the air conditioning process, and how it works, a lot better after watching this video than I did after completing the courses. Nice job!
hey, just want to let you know that i knew nothing about my AC and how it works until i binge watched all of your videos last sunday trying to fix mine.. Traced it to a bad transformer with your help. You a much appreciated. Thanks!
I am in a HVAC class and was struggling to catch on to stuff so started looking for videos just for some extra clarification and this was really helpful!!
You are the man! Seriously you always know the best way to explain things! I can’t tell you how much better of a HVAC Tech I am because of you! Thank you thank you thank you
thanks so much! Good explanation and as simple as can be. Now I understand how theses units work.
im a home inspector in training and this was by far the best from any book I read so far.
in trades school as a millwright, we were taught very basic refrigeration. this definitely helped me wrap my head around it for the tests, thank you!
Spoken in terms I could understand and keep up with. Thanks for sharing.
Finally a good explanation of this! I have watched many videos about this and this is by far the clearest one. If you watch this and the This Old House video about how heat pumps work (there are a couple of them, look for the one that's about 8:30 long), which shows 2 good examples of how pressure can increase or decrease the pressure of a gas, and you will understand this all. I think the key confusing point is, what is the interaction between the air and the refrigerant, which you explain very well. It's also confusing where the compressor and the evaporator are in this process of the refrigerant moving around. Again, you nailed that. Thanks much! (For anyone who actually read this far, the basic concept is the refrigerant stuff is really cold when it's in the house -- that's when you pass air over the pipes the refrigerant is in to make that air cooler -- and really hot when it's outside the house -- that's when you pass air over the pipes to "send" that heat outside. The rest of it is just the mechanical details of how you make the refrigerant really cold and then really hot... as is well explained in this video...)
Excellent explanation, you are a natural coach, trainer.
Great explanation!
Hola, Dummy here. And if I didn't really feel dumb because of my lack of knowledge of the AC system, I certainly feel dumb after the Coin Trick. Good job on the explanation. I at least now can make an educated guess at where my problem is. Thax
Very simply explained. It's always nice to have the mysteries taken out of common appliances. Thank you. GREAT job!
Thank You for explaining how the air conditioner works. Our air conditioner isn’t working very well and I want to be able to understand enough about how it works so I will be able to carry on a conversation with our air conditioning repair tech. This helps me better understand what he’s telling me, and probably makes his day easier as well 👍
Thanks, this is a very good way of explaining this topic. I have searched many times for it but, didn't quite understand the exchange part.
Very good tutorial, simple and to the point. What I was looking for, thanks!
Very good explanation of a somewhat complex system. I liked the additional diagrams you showed in addition to the explanation.
Excellent job Jay! It takes a really good understanding of something to frame a very complex and easily confused process such as air conditioning and boil it down into an easy to understand short presentation. Great job on doing just that. It takes a lot of thought to present what you did vs. a 30 plus minute pitch that is highly technical.
Thank you Holt! I appreciate this comment since you are right on. I found myself stopping and scratching my head multiple times during the filming of this video. Turns out it's not that easy to try to simplify the explanation :) Have a great weekend my friend!!
Good job Jay. Solved the puzzle in 1 second.
Oh wow! That is amazing! Most people don't end up solving it at all! (including me heh) Congratulations!! You are on a genius level and are destined for legendary feats :)
simple and clear. Thanks for the explanation and the mind bender at the end..!!
I have a 3.5 years old boy . He’s your fan. Recently I discovered he watched some of your videos. And he just watch over and over. He’s so much into all kinds of electrical appliances, washers, dryers，dishwasher, ac, fans, hairdryers, etc. he wonders how does them work, different part’s name...
often after he watched videos, he tries to tell or ask me or his dad tons stuff. A lot is really beyond me or his dad‘s knowledges. Maybe this boy has some kind of talent . I’m not sure.
We live in Eustis fl. I was looking maybe engineering class for him. Unfortunately so far I didn’t find any yet. He’s too little for all kinds engineering class I have found on line. I post this hope there’s similar kids and maybe I can get more information from their parents.
Sound like me when I was little
Got here by accident- was trying to see if it's OK to run the AC and the heat inside my CAR. Drove quite aways to a friends' house during really cold weather, and my defroster couldn't keep up this time, it was so cold. Have used the AC before to get rid of the fog, but this was actual ICE forming.
Couldn't figure out the proper way to prevent while I was driving, but safely home wanted to look it up. Unfortunately, the explanations I've read so far, were not well-explained as you did here. I now have a better grasp on it, before I had none. NIce video!
This is the best video I've seen explaining how air conditioners work, I think because he mentioned the physics principle that heat always travels to the cold.
So the heat in your room travels to the evaporator, and the heat in the condenser travels to the outside air.
One thing I'm wondering about is how those units that are outside the house are protected from the rain and snow? What stops the rain from destroying the outside units?
Thank you! Your explanation was very easy to understand.
Dude I've been working on my AC unit from a problem first point of view. I should have learned how it works instead of fixing/guessing the problem and praying it would work. Thanks bud.
Even as a former contractor who had to deal with hvac I never had clue as how ac worked. really good job of explanation. I will probably watch it again to to make sure I got all the physics involved
Awesome! Glad to hear that the video was easy to understand and follow. Even though I tried to explain it in a simple way, it is still a bit of a complicated topic..
Really good video my friend thanks for the information now I know 👍👍👍
sometimes the most expert still end up learning from daily life lessons. Glad to see you being 100
I took an A/C class about 10-12 years ago just for fun . and was talking to a friend recently and forgot how it worked . Your explanition brought it back , thank you
You left out one thing Jay.....as temperature goes up....the wife gets meaner!
Hahaha I love it! :) Very true..
tony tran 😂
...oh lord............. 🤣
HA! That's exactly why I'm here!
"Your wife is SUPER HOT!! Better fix the A/C!"
Excellent teacher. Thank you!
Thank you Joe! Glad you liked the video!
Hey! Bonus points to YOU for throwing in a fun twist at the end! 👏🏼👍🏻
I appreciate the bonus points! :) Thank you for watching and leaving a comment!
Your videos have been extremely helpful. We had no idea what was going on when our AC started blowing warm air. Very grateful for your expertise! Thank you
Thanks for taking the time out to explain, I am new in the field and only required to get the universal 608 for a maintenance position at a hospital. But the exam makes less sense if you don't understand the dynamics of a standard A/C unit. Your explanation cleared up quite a bit of questions and I'm grateful.
very good and thorough explanation. good job. much appreciated
Been watching you for 3 years since I started my career and you've helped out a lot thank you for you're helpful videos
Great video for dummies like me. Thanks
Thanks so much for the info.
We live in Florida and this summer has been Brutal!
Your video is very much appreciated!😊
Thank you Jay for explaining it in simple terms.
Very smart guy to explain how A/C system works. Thanks
Young man explains it very well
Thanx. I can listen and listen you forever!
Thank you for a first rate video! I’ve only just recently learned about the refrigeration cycle, as I have started working in buildings automation control, with most of that automation applying to HVAC. Since I work in controls, and not actual HVAC, I don’t need to know as much as an expert like yourself, but I still need to know the fundamentals. Your video not only clears some things up, but piques my interest and makes me want to learn more about HVAC!
You have quite the knack for explanations and teaching in a learnable way! Thank you for the videos. Do you have a video in regards to how to check a compressor or testing a relay on an exterior unit?
Thank you!! Yes I believe I have a video on both of those topics:

Great job explaining by using only basic science principles. Thank you!
GREAT JOB!!!!!!!!!!!
AWESOME BREAKDOWN!!
MANY BLESSINGS FOR YOU & YOUR FAMILY FOR YOUR TIME THE SHARING KNOWLEDGE
THIS HAS TOTALY HELPED ME UNDERSTAND THE CONCEPT THAT WILL HELP ME & MY FAMILY BRING FRUIT TO OUR HOME THROUGH MY JOURNEY AS AN HVAC TECH!,
THANK YOU!
Awesome job explaining how the Air Conditioner works.
Great video, now I know how it works. Thank you.
Great job. I watch all your videos. Thank you.
So helpful. Thank you! I need to have my AC unit replaced and now I understand how it works.
Thank you for explaining it so that I could understand how the system works.
Great video, very good explanation on how heat transfers, thank you.......
You did a pretty good job of simplifying this technical topic. Well done.
This is a fantastic channel and you are a great teacher. Excellent video, thoroughly explained and visual references made this an easy to understand concept. I appreciate the knowledge you share with the viewers. Thank you!
I came up a nickel short ...You got the best and prettiest camera woman on TH-cam ... Just saying' ... Great little vid ...
As did I... Why thank you! I will have to agree with you on that one! She is pretty amazing indeed! I sometimes wonder how much worse many of my videos would have been without her assistance.
Love it! Thank you so much for the best explanation I've found!
You're definitely one of the best !!
Thank you for your channel !!!
You have made this so easy to understand... thanks👍i always got lost with the more technical explanations..lol
Great job explaining this Jay. “ If you can’t explain it simply, you don’t understand it well enough.” Albert Einstein
I have learned a lot from these tutorial videos. Keep up the great work Jay. 👍
Great information. I now understand what the tech is talking about.
unique video...got the exact working of the air conditioner...
I just had our home A/C unit replaced. Now I understand how the darn thing works, thanks for posting this!
Love the way you make things simple to understand
Thanks for the explanation! Very interesting!!!!
Nice and easy to follow. I had just watched a 4 minute confusing tutorial then found this which was perfect for what I needed,
Thank you for sharing this video explaining in simple terms so that ordinary people can understand.
From a long time teacher - you are a natural teacher. You have the talent and wisdom it takes to explin HOW people need to hear in order to understand. I give you an A+ 4.0 rating for AC education! Sorry - simple puzzle when you are used to thinking outside the box!
Nicely explained. Thx.
thank you so much for your advise this is one of the best video that I never seen . thanks again
Thanks for that beautiful explanation!
Very helpful analogies …thanks!
awesome easy to understand video I am going to an HVAC/R trade school soon and your video is just what I need to give me that edge in the gam thank you so much!
Thank you for the explanation. Definitely helped
Was a well-explained video of how an air conditioner works.
I watched another video with cool graphics and nice editing, but let me tell you your explanation left no dudes in my mind. I even feel like I can explained to others.
Love to hear that was easy to understand! Thank you!
Thank you for this video. I live in an apartment complex and many times in the summer the management likes to BS the tenants about why they cannot fix our broken central AC. Now I have some information that will help me to understand what is going on.
Thank you for breaking it down, I needed to get the basic principles in my mind first before understanding how the system parts work. Wish all my teachers would start out with the basics first, they all seem to be more concerned about showing how smart they are than successfully teaching me something.
You're welcome! Glad I could provide a basic breakdown. I can sympathize with you about the teachers since I remember occasionally having those same thoughts when I was going to school too..
Great job explaining the ac system. 👍
Thank you!! I appreciate you watching and leaving a comment!
good job. you made it pretty understandable without getting too technical
Great explanation good stuff
I love working on ac keep give me good videos about ac love it 😀
Thank you Osvaldo!! Glad to hear you are enjoying the videos!
Great job explaining this. Really helpful. I had to pause a bunch to write down all the terms lol but great and easy to learn.
