1. Towards the end you said basically what you are doing is taking the heat from inside and dumping it where it isn't needed or something to that effect. Couldn't you put another heat exchanger in and dump that heat into a tank in your basement for domestic hot water and practically double the efficiency? Yes, you would need to add a tank in your basement and plumb to it but it would remove more heat from the super heated refrigerant cumming out of the compressor and it would be that much heat that would not be needed from the water heater. Why don't manufacturers do that? the heat exchanger would be under $200
2. Great training , helped me on my  NATE-ICE
3. Great video! Very informative!
4. Thank you so much :)
5. excellent educational video...Thank you Ron
6. Hi,
   The info you have provided has been clear, explicit, interesting and factual. This video has broadened my knowledge of refrigeration.I am a qualified electrical engineer  and repair numerous diverse electrical systems including refrigeration. The video is excellent many thanks
7. thank u very much sir , may,God bless u for this wonderful efforts 
8. Really nice video! I just wished you used Kelvin degrees!
9. Nice work Brother - really nice work!
10. Hello Mr. Walker. Thanks a lot for taking your time making this wonderful video. It is very helpful, and can guide a lot of people like me, who want to become an HVAC tech. It will be even more appreciated if you could make some introductory videos on how to become a tech and some useful material through which you could endorse your services too. Keep the good job and caring for others!
11. well done...best video I have seen. I liked the way you explained stuff....made it really easy, even for a hard head like myself..lol
12. This is a better explanation of refrigeration than you would receive spending 2k to attend a class in Thermodynamics. It wasn't until I was working with ammonia gasses designing a special kind of engine that I fully understood air conditioning (by noticing that ammonia when expanding through a valve causes the vapor in air to freeze on the expansion valve because it's absorbing the heat from the surrounding air.) , I'm nevertheless refreshing my HVAC knowledge in order to hopefully score a job in the industry.
13. Thanks lot sir... It is really useful. 
14. Thank you. My heat pump compressor failed. I watched tech. put new one in unit. Fasinated asking him questions how it worked. He did his best to explain it. Been watching videos for hours trying to understand the workings . THANK YOU VERY MUCH AND GOD BLESS YOU FOR YOU HAVE HELPED ME GREATLY.
15. Thank you Ron, I am currently enroll for a refrigeration class,  for a NYC refrigeration license. Your explanation  made it so much simpler. Thanks again.
16. Awesome video thank u!!!!!!
17. Thanks ron for your time taken to put this video together,i now understand fully,the basic refrigeration circle,pls can you post some video about LATENT HEAT OF VAPORISATION, AND SENSIBLE HEAT,I REALY NEED MORE EXPLANATION ON THAT  THANK YOU
18. excellant explanation
19. Thank you for making this video now I understand my class so much better.
